BHA peel
BHA peel is applied to the skin and removed after a certain time. It can help reduce acne and pigmentation spots and make the skin look smoother and more even.
Such a scrub is particularly good for people with oily and acne-prone skin, but it can also be used for other skin types.
It is important to note that it is always advisable to consult a dermatologist or dermatologist before exfoliating, especially if you have sensitive skin.
What is the main active ingredient in a BHA peel?
Salicylic acid, or 2-hydroxybenzoic acid, is found in the form of its ester in essential oils and as a plant hormone in the leaves, flowers and roots of various plants. It has a great importance in the defence againstpathogenic substances.
Salicylic acid got its name because it used to be obtained mainly through the oxidative processing of salicin, which was found in the bark of various willows.
It is also called spiric acid. It got this name because it can also be extracted from the sap of the spirea. The salts of salicylic acid are called salicylates.
Salicylic acid belongs to the aromatic compounds because of the benzene ring it contains. However, since it also contains both a carboxy and a hydroxy group, it belongs to the hydroxycarboxylic acids. Because of its beta-stability, it is also called ß-hydroxycarboxylic acid.
The hydroxy group is directly attached to the benzene ring, so that salicylic acid also belongs to the phenols.
Salicylic acid is used in the production of dyes and perfumes, and preparations which are used as analgesic, anti-inflammatory and blood thinning drugs.
Salicylic acid in cosmetics
In a concentration of up to 2%, salicylic acid is a common ingredient in cosmetics. In this concentration, it is found in the typical BHA peels, BHA serums or as a BHA exfoliant. From a 5% solution, it shows a keratolytic and thus also comedolytic effect that is sufficient for acne therapy.
From a 10% solution, it is mainly used for the treatment of corns and warts.
Due to irritating effects, BHA peels should not get into the eyes or mucous membranes and use should be avoided in case of hypersensitive skin.
BHA products have become standard products for cosmetic brands and should not be missing from any facial line.
What other BHA acids are there?
The most commonly used BHA acid is salicylic acid. However, there are other BHA acids such as β-hydroxybutyric acid and mevalonic acid. Salicylic acid is often used in higher concentrations and is a stronger exfoliating agent than the other BHA acids. The other BHA acids are of no importance in cosmetics.

BHA peel – the classic for impure skin
The BHA peel with 2% salicylic acid is the standard product for impure skin. For blemished skin or skin prone to acne, salicylic acid is very effective and can rid the skin of dead skin cells and shrink pores. It can help reduce acne and pigmentation spots and make the skin look smoother and more even. Such a BHA peel serum can also increase the skin’s moisture and promote circulation. It is especially good for people with oily and acne-prone skin.
