Use of Salicylic Acid in Lotion
Salicylic acid is widely used in the field of dermatology. An ingredient in many skin care products sold both over the counter and by prescription, salicylic acid is effective in treating a variety of skin conditions when applied topically. Salicylic acid is derived from the bark of willow trees, and has a chemical make-up similar to aspirin, explaining its historical use as a pain reliever and fever reducer. Its role in skin care lotions is more recent and increasingly popular. Does this Spark an idea?

About Salicylic Acid
-
Salicylic acid is a colorless, crystallized beta hydroxy acid (BHA) that works as a plant hormone. It is derivative of salicin metabolism. Chemically, it is similar to acetylsalicylic acid, the main component of aspirin. In the cosmetics market, the term BHA is often used interchangeably with salicylic acid.
How Salicylic Acid Works in Skin Care
-
Salicylic acid expedites the natural skin process of exfoliation, triggering old cells to shed off of the skin's surface. It is able to deeply penetrate into the skin pores and dissolve build-up and oil around hair follicles. It also prevents the pores from clogging up, and prevents bacteria build-up, which subsequently halts potential redness and blemishes that can arise from excess dirt and oil. Salicylic acid also makes excess, unusable skin cells removable by breaking down the skin protein keratin.

Uses in Skin Care
-
In skin care products, salicylic acid is used in varying strengths that range from 0.5 percent to 30 percent. The highest concentrations are used to treat calluses and warts. Lower concentrations are used to treat acne, since the acid prevents bacteria build-up and clears out excessive dirt and oil in skin blemishes. It's also used to decease the inflammation of whiteheads and blackheads. Because of its exfoliating properties, salicylic acid is used in anti-aging skin care products. It is most widely used in lotions (and other forms of topical application) that aim to correct problematic skin, and in lotions that are designed to reduce and combat the visible signs of aging.
Side Effects
-
It is important to consult with a dermatologist before incorporating salicylic acid lotion into a skin care regimen, since skin reactions to active ingredients vary, and allergic reactions to any new ingredient are always possible. The most common side effect is dry skin, and in extreme cases, scaling skin. Stinging may occur on the treated area. Peeling may also occur. After treatment, the skin may also experience redness. If these effects persist beyond a week, consult your dermatologist.
Precautions and Warnings
-
Again, consult a dermatologist, not only to consider skin reaction, but also to share information on other active ingredients in the skin care regimen, which will not always work well with salicylic acid. Abrasive cleansers, products with high alcohol or sulfur concentration, products with benzoyl peroxide or Retin-A, could irritate the skin intensely when used in conjunction with salicylic acid. The dermatologist will also consider a patient's diet, medication, and vitamin supplements, when determining whether salicylic acid is necessary and in what quantity. It should not be used on patients who have or have had liver or kidney disease; nor should it be used on children or teens with the flu or the chicken pox.
