Cooling agents for bruises: gels and ointments

A soft tissue contusion occurs when a blow or fall damages small blood vessels in the skin and underlying tissue, resulting in hemorrhage, swelling, and pain. Initially, the body initiates a normal inflammatory response, which helps remove damaged cells and restore tissue. Cold is used in this situation not to suppress inflammation, but primarily to reduce pain and excessive swelling. [1]

The classic approach to first aid for soft tissue trauma has long been described as "rest, ice, compression, and elevation." Modern reviews show that ice and other local cooling options do reduce pain and can limit excess swelling, but there is little convincing evidence that they accelerate healing. Therefore, cold is now viewed primarily as a symptom control method rather than a universal recovery "accelerator." [2]

New concepts in sports medicine offer a more gentle and individualized approach. Recommendations such as "PEACE and LOVE" shift the emphasis to protecting the injured area, moderate movement, patient education, and gradual loading. Ice and strong inflammation suppression are considered cautiously, so as not to interfere with the natural healing process. This does not mean that cold is no longer necessary, but it should be used judiciously and briefly. [3]

Cooling ointments and gels emerged as an attempt to combine the "cold" effect with ease of use: they can be applied quickly, don't require ice or special compresses, don't spread, and deliver a cooling sensation at the desired point. Moreover, they work through the skin's nerve endings and subjective sensations rather than through deep, physical "freezing" of the tissue, like ice. [4]

It's important to understand the limits of your options right away. A cooling ointment can help reduce pain and discomfort, make the first few days after an injury more bearable, and sometimes slightly reduce swelling. However, it cannot replace an examination if you suspect a fracture, ligament tear, significant intramuscular hemorrhage, or infection. Any severe or unusual pain is a reason to see a doctor, not just look for a more powerful ointment. [5]

Table 1. Cold for bruises: ice, cooling ointment, and no cooling

Approach	The main goal	Pros	Disadvantages and limitations
Physical ice	Reduction of pain and swelling	Rapid, pronounced cooling	Requires conditions, risk of skin hypothermia
Cooling ointment or gel	Pain relief, comfort	Convenient, can be applied anywhere, no drips	The sensation of cold is often superficial, and the effect on healing is limited.
No cooling, just rest	The natural course of inflammation	There is no risk of hypothermia	Pain and swelling may be more severe

What are cooling ointments and gels?

Cooling ointments and gels for bruises most often contain a combination of substances that produce a cooling sensation, distract from pain, and slightly improve local circulation. Key components include menthol, camphor, alcohol base, essential oils, and sometimes menthyl lactate, borneol, and other substances. These are so-called "counterirritants": they create a strong but relatively safe signal in the nervous system, reducing the perception of primary pain. [6]

Menthol is the most studied component of cooling agents. It activates special TRPM8 ion channels on the skin's sensory nerve endings, which respond to cold. As a result, the brain receives a signal that the skin has been exposed to a lower temperature, even if the actual cooling is minimal. Menthol also participates in complex cascades, influencing other ion channels and pain-inhibiting systems in the central nervous system, which explains its analgesic effect. [7]

Interestingly, studies show that menthol-based cooling gels don't always significantly reduce skin temperature, but patients clearly feel coolness and pain relief. In a number of studies, menthol gel provided comparable or even greater muscle pain relief than traditional ice. This confirms that the key factor here isn't physical tissue cooling, but rather changes in pain perception and thermal sensations. [8]

In addition to menthol, cooling ointments may contain camphor, methyl salicylate, and borneol. Camphor has a mild analgesic and distracting effect, while methyl salicylate simultaneously acts as a local "relative" of nonsteroidal anti-inflammatory drugs and can enhance the analgesic effect. Borneol, according to some studies, can also reduce pain. However, the more active ingredients, the higher the risk of skin reactions and allergies, especially in people with sensitive skin. [9]

The base of the preparation is worth mentioning separately. A water- or alcohol-based gel dries faster and creates a more pronounced cooling sensation due to the evaporation of the liquid. An ointment base is more oily and stays on the skin longer, but the cooling effect may be less pronounced. The choice depends on the goals and preferences: for quick relief in the first hours after an injury, many patients prefer a gel, while for a more lasting effect on a small area, an ointment is sometimes more convenient. [10]

Table 2. Main components of cooling ointments and their effects

Component	Main action	Features and limitations
Menthol	Cold sensation, pain relief via TRPM8	At high concentrations, painful sensitivity to cold may occur.
Camphor	Mild pain relief and distracting effect	May cause skin irritation in sensitive individuals.
Methyl salicylate	A local "analgesic" related to salicylates	For large application areas, there is a risk of systemic absorption.
Borneol	Additional analgesic effect	Data is limited, allergic reactions are possible
Essential oils	Weak anti-inflammatory and distracting effect	Often provoke allergies and dermatitis
Alcohol or gel base	Rapid evaporation and surface cooling	Dry and sensitive skin may experience dryness and irritation.

When is cooling ointment appropriate for bruises and when is it not?

Cooling ointments and gels are most appropriate for mild to moderate soft tissue contusions, where there is moderate pain and a small to medium-sized hematoma, but movement is preserved, support is possible, and there is no severe deformity. In this situation, the goal is to reduce pain and make the first few days more comfortable while the body heals the injury. Cooling gel can complement physical cold, elastic bandaging, and gentle exercise. [11]

If the injury is recent, simple physical measures remain the priority during the first few hours: protection, limited weight-bearing, cold, compression, and elevation of the limb. These protocols help limit initial swelling and hemorrhage. Cooling ointment can be used as an aid at this time, but should not replace ice and injury assessment. It is especially important not to mask severe pain and joint instability with a "pleasant coolness" applied to the skin alone. [12]

Avoid relying on a cooling agent if you suspect a fracture, muscle or ligament tear, massive hematoma, severe deformity, or inability to bear weight on the limb or move the joint. In such cases, the ointment may temporarily reduce pain, but it won't solve the problem and will only delay seeking medical attention. The patient's priority is to see a traumatologist as soon as possible, not seek out the strongest gel. [13]

Large hematomas require caution, especially in people taking anticoagulants or medications that affect blood clotting. For them, even a minor blow can cause significant bleeding. In such a situation, a cooling ointment with active ingredients is far from the primary measure. First, it's necessary to rule out dangerous bleeding, evaluate the blood tests, and only then decide whether any topical treatment is necessary. [14]

Open wounds, abrasions, and areas with signs of infection are particularly restricted. No cooling ointments should be applied to damaged skin, especially those containing menthol, camphor, or salicylates: these increase irritation, increase the risk of components entering the bloodstream, and complicate healing. If skin damage occurs, the wound should first be treated and, if necessary, medical attention should be sought. Local anesthetic gels should be applied only around, not directly to, the wound. [15]

Table 3. Examples of situations and the role of cooling ointments

Situation	What's happening	Can I use cooling ointment?	What is most important
Minor bruise of the shin without loss of support	Local pain and bruising	Yes, in combination with cold and peace	Protection, elastic bandage, observation
Moderate hip contusion, pain with movement	Moderate hematoma, edema	Yes, after ruling out a fracture.	Physician's assessment, functional treatment
I can't step on my foot, there's severe pain.	Suspected fracture or ligament rupture	No, diagnostics first	See a traumatologist immediately
Large hematoma in a patient on anticoagulants	High risk of ongoing bleeding	Only by doctor's decision	Monitoring of tests and the source of bleeding
Bruise with skin abrasions and scrapes	Open injury	No, do not apply the ointment to the wound.	Wound treatment, surgeon if necessary

The effectiveness of cooling gels and ointments: what research has shown

Clinical studies of cooling gels for soft tissue injuries show that such treatments can indeed reduce pain and improve function faster than placebo. In one randomized trial, a cooling gel containing menthol and other ingredients provided faster pain relief and decreased motion limitation compared to an inactive gel in patients with acute sports injuries. [16]

Studies comparing menthol gels with traditional ice have yielded interesting results. In several studies, menthol gel provided comparable or greater reductions in pain and muscle tension in cases of muscle soreness and localized muscle pain. The reduction in actual skin temperature was moderate, with the primary effect being changes in pain perception via the cold receptor system. [17]

However, when analyzing the impact on the rate of healing of soft tissue injuries, the picture is more muted. Reviews of cryotherapy show that the evidence for accelerating recovery with ice or other cooling methods is limited and inconclusive. Many studies document a good analgesic effect but find no clear benefit in terms of return to activity or reduced risk of complications. It is logical to assume that the situation is similar for cooling ointments: they help to cope with the injury, but do not turbocharge recovery. [18]

For comparison, it's useful to look at data on topical nonsteroidal anti-inflammatory drugs. Large reviews show that gels containing diclofenac, ketoprofen, and other nonsteroidal anti-inflammatory drugs (NSAIDs) for acute sprains and bruises provide significant pain relief and swelling reduction comparable to tablet formulations, but with a lower risk of systemic side effects. Therefore, many clinical guidelines consider these gels first-line treatments for soft tissue pain, while purely cooling formulations remain adjunctive. [19]

Thus, cooling ointments are logically considered a symptomatic treatment tool that can be combined with other methods. They are particularly useful when the patient does not tolerate ice well, is unable to regularly apply cold, or requires rapid local pain relief before short-term activity. However, the mainstay of treatment remains protection of the injured area, functional restoration, and, if necessary, medications with proven anti-inflammatory action. [20]

Table 4. Data on the effectiveness of cooling gels and alternatives

Means	The main result in the research	Conclusion
Cooling gel with menthol	Reduced pain and limitation of motion faster than placebo	Useful for symptom control
Menthol ice gel	Comparable or better pain reduction for DOMS	Suitable as an alternative to ice in some cases
Physical ice	Good pain-relieving effect	The effect on healing is controversial.
Topical nonsteroidal anti-inflammatory drugs	Severe pain relief and reduction of swelling	First-line treatments for many injuries
Combination gels	Moderate reduction of pain and swelling	The effect depends on the composition, the data is heterogeneous

Safety and side effects of cooling ointments

When used correctly, cooling ointments and gels are generally well-tolerated. Most common adverse reactions are limited to the skin: redness, itching, dryness, a burning sensation, and sometimes urticaria-like rashes. The risk is higher in people with sensitive skin, atopic dermatitis, or allergies to essential oils or specific components of the product. If severe irritation occurs, wash off the ointment and discontinue use without consulting a doctor. [21]

Menthol in high concentrations can cause a paradoxical increase in sensitivity to cold and even a painful reaction to cool stimuli. Some studies describe the phenomenon of "cold allodynia" with excessive exposure to menthol, where even slight cooling is perceived as painful. Therefore, it is important to adhere to the recommended frequency of application and not apply too thick a layer. [22]

Methyl salicylate and other salicylates found in some cooling agents require special attention. When applied to large areas, especially under dressings and for prolonged periods, significant absorption and the risk of systemic effects similar to those of salicylates are possible. Cases of toxicity in children and adolescents have been reported with overuse of such creams. Therefore, individuals with bleeding disorders, peptic ulcers, or severe renal or hepatic impairment should use such medications with extreme caution and, if possible, choose salicylate-free options. [23]

It is not recommended to apply cooling gels to large areas of the body, under occlusive dressings, or immediately after a hot shower, when skin vessels are dilated and absorption of active ingredients may be enhanced. Combination with other topical agents, especially nonsteroidal anti-inflammatory drugs or heparin, increases stress on the skin and may theoretically increase the risk of irritation and bleeding. The optimal approach is to use one product at a time, and if a combination regimen is necessary, discuss it with your doctor. [24]

People with bronchial asthma, polyvalent allergies, and sensitivity to aromatic substances require special attention. Essential oils and strong-smelling components in ointments can provoke not only skin reactions but also respiratory symptoms. In such cases, it is preferable to choose products with a minimal number of components and without a strong odor. If you have a severe allergic reaction, avoid such products entirely in favor of simple ice and functional therapy. [25]

Table 5. Main risks and how to minimize them

Risk	What causes it?	How to reduce the likelihood
Skin irritation and redness	High concentrations of menthol, camphor, essential oils	Choose moderate concentrations, apply in a thin layer
Burning and painful sensitivity to cold	Excessive amount of menthol	Follow the instructions, do not exceed the recommended dosage.
Systemic action of salicylates	Large areas of application of preparations containing methyl salicylate	Use such products locally and for a short time.
Allergic reaction	Individual intolerance to components	Do a test application on a small area of skin
Enhanced absorption under dressing	Occlusive dressings and hot showers	Do not apply tight dressings or immediately after a bath.

Special groups: children, pregnant women, elderly patients and athletes

Children have thinner skin and a larger surface area relative to their body weight. This means that any topical medications, including cooling ointments, may be absorbed more effectively. For small children with minor bruises, a cold compress, rest, and time are usually sufficient. Gels containing menthol, camphor, or salicylates should only be used on the advice of a pediatrician and should be applied to limited areas of the bruised area. [26]

For pregnant and breastfeeding women, the choice of any medication, including topical ones, is more cautious. Most components of cooling ointments have not been studied in clinical trials specifically in the context of pregnancy and lactation, so official instructions often recommend their use only when clearly necessary and after assessing the risks and benefits. For minor bruises during this period, it is wiser to limit the application to physical cold, a gentle regimen, and observation, and consider cooling gels as an additional option only after consulting with a doctor. [27]

Elderly patients often take multiple medications simultaneously, including anticoagulants, antiplatelet agents, and medications for chronic pain. They are at higher risk of side effects from any topical pain relievers than younger, healthier individuals. For this group, short-term use of cooling ointments on small areas is advisable, with the attending physician being informed of all medications used, even if they are "for topical use only." [28]

Athletes and physically active individuals are particularly prone to using cooling ointments and gels. It's important for them to understand that such products shouldn't mask serious injuries or encourage a premature return to activity. Professional sports also adhere to anti-doping regulations, although most menthol and camphor gels are permitted, and restrictions primarily apply to systemic medications and glucocorticoids. The optimal strategy for athletes is to coordinate the selection of products with a sports medicine physician and physiotherapist. [29]

For people with chronic skin conditions such as eczema or psoriasis, any new topical treatment can trigger a flare-up. For these individuals, choosing a cooling ointment should be especially careful: it's best to choose products with minimal fragrances and potential allergens, and if in doubt, consult a dermatologist. [30]

Table 6. Special patient groups and approach to cooling ointments

Group	Key Features	Recommendations for use
Children	Increased absorption, sensitive skin	Only as prescribed by a doctor, in small areas
Pregnant and lactating women	Limited safety data	If possible, avoid using ointments; if necessary, consult with your doctor.
Elderly patients	Polypharmacy, chronic diseases	Short courses, small area of application, inform the doctor
Athletes	High loads, risk of masking injuries	Use as a complement to, not a replacement for, diagnosis and rehabilitation
Patients with dermatoses	Tendency to exacerbation of skin diseases	Selecting products with a minimum number of components, consultation with a dermatologist

A practical guide to choosing and using a cooling ointment for a bruise

The first step is to assess the severity of the injury. If the injury causes severe pain, inability to put weight on the foot or use the hand, or if there is limb deformity, severe joint instability, or unusual swelling, the priority is to immediately take the injury to a doctor. In this scenario, ointments and gels are of secondary importance until a fracture, ligament tear, or other dangerous conditions are ruled out. [31]

If the injury is mild or moderate and shows no signs of danger, a simple approach is most effective in the first few hours: protect the injured area, reduce stress, apply cold through a cloth, elevate the limb, and apply an elastic bandage if necessary. This approach reduces excessive swelling and alleviates pain. Cooling ointment can be used in addition during this period, but it is important not to apply it under a bandage or to use it as the sole treatment. [32]

From the second day, if the condition is stable and there are no signs of deterioration, the focus can shift to comfort and functional restoration. A cooling gel or ointment is applied in a thin layer to the injured area one or several times a day according to the instructions, gently, without harsh massage. At the same time, begin gentle joint movements, light exercises to maintain mobility, and, if necessary, add gels containing nonsteroidal anti-inflammatory drugs as recommended by a doctor. [33]

After a few days, if the process is normal, the bruise changes color, swelling decreases, pain gradually subsides, and the need for cooling ointments diminishes. These can be gradually discontinued, with the emphasis remaining on physical therapy and normal activity, gradually increasing the load. If, however, after 5-7 days, the pain remains significant, swelling persists, or new symptoms appear (fever, redness, throbbing pain), a follow-up examination by a specialist is necessary. [34]

It's helpful to think of cooling ointment not as a "primary cure for a bruise," but as an additional tool that helps you get through the first few days of an injury and facilitates exercise. The foundation of safe recovery is an adequate injury assessment, reasonable load limitation, gradual activation, and the use of proven pain-relieving and anti-inflammatory agents when needed. [35]

Frequently asked questions about cooling ointments for bruises

Does a cooling ointment help a bruise disappear faster?
Cooling agents primarily reduce pain and create a feeling of coolness. Actual improvement in hematoma absorption is more often associated with the natural progression of the process and the effectiveness of mechanical measures and, if necessary, other medications. Some gels may combine cooling components with substances that improve microcirculation, but don't expect the bruise to "disappear overnight." [36]

Can ice be replaced with a cooling ointment alone?
For pain control, a cooling gel is sometimes comparable in effectiveness to ice, especially if ice is difficult to apply. However, for limiting initial swelling after a serious injury, physical cold remains a more predictable tool. Ideally, they are used together, with the ointment considered a convenient supplement rather than a complete replacement. [37]

Can I apply a cooling ointment under an elastic bandage?
A small amount of gel under a loose bandage is sometimes acceptable, but a tight seal and thick layer can increase absorption and skin irritation. Unless recommended by a doctor, it's best to apply the ointment to clean, dry skin, allow it to absorb, and then apply a separate bandage if needed. [38]

How does a cooling ointment differ from a gel containing nonsteroidal anti-inflammatory drugs (NSAIDs)?
A cooling ointment primarily acts on the nerve endings of the skin and subjective sensations, creating a cooling effect and distracting from pain. A gel containing an NSAID additionally reduces local inflammation and swelling in muscles and ligaments. Therefore, for severe pain and functional limitations, doctors often recommend NSAIDs, leaving cooling solutions as a supplement. [39]
