5 Common Misconceptions about Salicylic Acid.

Thesalicylic acid is a acid beta-hydroxy (B.H.A.), which derives its name from the bark of the willow tree. This organic element is also found in certain fruits and vegetables such as cherries, cucumbers, tomatoes, and spinach.

Salicylic acid has been used since ancient times for its pain-relieving properties and its ability to inhibit the growth of bacteria. The well-known aspirin is a synthetic derivative of salicylic acid: it is acetylsalicylic acid. It was first manufactured in 1853 by the chemist C.F. GERHARDT.

In skincare, salicylic acid can be of synthetic or natural origin. According to Regulation (EC) No 1223/2009 on cosmetic products, its incorporation rate must not exceed 2% in non-rinse products. It is recognized for its keratolytic abilities. Indeed, salicylic acid helps to eliminate dead cells on the skin's surface that clog pores and give a dull complexion.

In higher concentrations, salicylic acid is considered a medicinal active ingredient capable of effectively treating targeted issues, such as acne, psoriasis, and even warts.

Moreover, salicylic acid is a cosmetic ingredient authorized in organic products.

   Note : The European regulation on cosmetics has banned the use of salicylic acid in hygiene products for children under 3 years old, as it can cause eye irritation if it comes into contact with the eyes.

2. Salicylic acid is used exclusively on the face.
