Facts and Myths About Salicylic Acid Products.

Salicylic acid is a beta-hydroxy acid (BHA), which gets its name from the willow bark. This organic element is also found in certain fruits and vegetables such as cherries, cucumbers, tomatoes, and spinach.

Salicylic acid has been used since antiquity for its analgesic properties and its ability to limit the growth of bacteria. The famous aspirin is a synthetic derivative of salicylic acid: it is acetylsalicylic acid. It was first manufactured in 1853 by the chemist C.F. Gerhard.

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

In higher concentrations, salicylic acid is considered a medicinal active ingredient

capable of effectively treating targeted problems such as acne, psoriasis, and even warts.

Salicylic acid products are used more and more today, but every so often the ingredient is controversial. We help you to sort out the truth from the fake:

1. Salicylic acid, as a cosmetic ingredient, can be dangerous for your health.

   Myth: The European regulation on cosmetic products limits the concentration of salicylic acid to 2% in non-rinse-off products, 3% in rinse-off products and 0.5% when introduced as a preservative. In 2018, the Scientific Committee on Consumer Safety (SCCS) issued a positive opinion on the use of salicylic acid: it is considered safe in cosmetic products at the concentrations at which it is limited. In addition, salicylic acid is an authorized organic cosmetic ingredient.

   Note: Because it can cause eye irritation if it comes into contact with the eyes, the European Cosmetics Regulation has banned the use of salicylic acid in personal care products for children under 3 years of age.

2. Salicylic acid is only used on the face.

   Myth. Indeed, it is present in facial care products in the form of a salicylic acid serum, lotion, night cream, etc. But it is also used in body care products and exfoliating creams for the feet. Some shampoos, conditioners, and hair lotions also contain this BHA. It effectively fights dandruff and cleanses the scalp.

3. Salicylic acid helps clear blemishes.

   Fact. Salicylic acid is a great ally for oily, blemish-prone and acne-prone skin. It prevents the growth and proliferation of fungi, viruses and bacteria, such as Cutibacterium acnes, the microorganism that causes inflammatory reactions in acne. Thanks to its keratolytic action, it helps to unclog pores, thus limiting the appearance of blackheads and pimples.

4. Salicylic acid restores the skin's radiance.

   Fact. Salicylic acid has astringent properties. It tightens pores and smoothes skin texture. Its exfoliating properties help remove dead skin from the stratum corneum that dulls the complexion. Moreover, it contributes to limit the excess of sebum which tends to make the skin shiny.
   

5. Salicylic acid is a photosensitizing substance.

   Fact. Salicylic acid skincare products can actually cause skin reactions when exposed to UV rays. For this reason, it's best to keep it to your evening routine and use a broad-spectrum sunscreen the next day and the days after.
