Salicylic acid gel is a topical beta hydroxy acid that comes from the bark of the willow tree. It is available by prescription and over the counter to clear and prevent acne. It is also used to treat skin conditions such as psoriasis, dandruff, corns, calluses, and warts on the hands or feet (plantar warts). Common OTC sources for this gel include products from Clearasil, Compound W, Neutrogena, Noxzema, Oxy Balance and others. Prescription-strength brands include DioPlant Gel and Trans-Ver-Sal.
Function
Salicylic acid is a keratolytic, or an agent that causes the outer layer of the skin to loosen and shed away in a process called exfoliation, which helps keep the skin pores clean and thus prevents acne. When the gel is applied to the affected area of the skin, it makes the skin swell slightly, soften and peel over time. The peeling effect is helpful for treating whiteheads and blackheads from acne. It is the only oil-soluble hydroxy acid, and it can penetrate clogged skin pores.
Effects
The main effect of applying salicylic acid to the skin is dryness, slight irritation, or flaking. This is how the drug works especially upon first use. These side effects are mild but sometimes the skin can also feel stinging or burning sensations. Apply small amounts until your skin adapts to the medicine. Talk to the doctor and carefully read the package information. A good deterrent for dryness is using a mild daily moisturizer.
Considerations
Do not use other gels or creams on the treatment area unless the doctor recommends it. Your skin may get more irritated or dry if you use other products that contain the same ingredient. Do not expect overnight results because it takes time for the gel to clear debris from the skin pores. Acne breakouts should diminish if you use the gel consistently, but do not apply it to large areas of the body. Also, do not use a bandage to cover a skim blemish that you are treating unless your doctor tells you to do so.
Misconceptions
Regarding acne, salicylic acid gel helps remove excess oils on the skin but it does not treat the underlying condition. Regarding warts on the soles of the feet (plantar warts), salicylic acid gel provides a temporary but effective treatment when applied three times daily, for about three weeks, until the wart shrinks or falls off the foot. However, the gel does not eliminate the virus that cause such warts, human papilloma virus (HPV).
Warning
Do not use salicylic acid gel for warts on other parts of the body such as the face, because it is only recommended for plantar warts. If you are treating acne, be careful when applying the gel around your eyes, nose, and mouth--it should not touch these areas. If it does, immediately wash the affected area with water. People with diabetes, blood pressure problems, or kidney or liver problems should not use this medicine. This gel can be harmful if swallowed--keep it away from children. Pregnant women or women who are nursing should talk to a doctor before using this product.
