What are the benefits of tartaric acid on the skin?

Thetartaric acid goes by several names, including dihydroxybutanedioic acid (its chemical name), L-tartaric acid, and names that describe its derivatives/salts. It is sometimes simply referred to as cream of tartar, Rochelle salt (potassium and sodium tartrate, which is a mild laxative), and emetic tartar (potassium tartrate). Its discovery is credited to the Swedish apothecary Carl Wilhelm SCHEEL and dates back to the 18th century.

Tartaric acid naturally occurs in a variety of plants, particularly in fruits that are rich in antioxidants. Among the richest sources are tamarinds, grapes, apricots, bananas, citrus fruits, dandelions, sugar beets, and apples. Today, it is typically derived from grapes or a byproduct of winemaking. In fact, it is this molecule that gives wine its characteristic tart taste. In winemaking, it helps to prevent deterioration due to bacterial growth and thus acts as a preservative. It is naturally present in wine after fermentation.

Furthermore, it is added to foods and even some medications and supplements due to its antioxidant and preservative effects, as well as its sour and tangy flavor. You will find it in foods/beverages such as carbonated drinks, fruit pastes, gelatin, ice cream, and baking powder. It can be used to enhance the taste of oral medications, and some of its derivatives, like antimony potassium tartrate, can be found in cough syrups and expectorants.

1. It's a gentle exfoliant

   Tartaric acid belongs to the family of alpha-hydroxy acids (AHA), which also includes theglycolic acid and thelactic acid. AHAs are keratolytic agents: they boost the skin's radiance by removing the often dull layer of dead cells that can cover it.

   Tartaric acid is "larger" than glycolic acid and therefore penetrates the skin less deeply. As a result, it is less irritating than glycolic acid and serves as a good alternative for individuals who wish to "renew their skin" but cannot tolerate glycolic acid. There is always a risk of allergic reaction or skin irritation, but tartaric acid is generally well tolerated.

2. It protects the skin from free radicals.

   Free radicals are reactive oxygen species naturally produced by the body. However, when cells are faced with a stress, they produce them excessively . single electron. They tend to react with other molecules to form a pair of electrons, and then cause damage to cells, DNA, and proteins in the body. Aging is thus accelerated and wrinkles appear on the skin surface.

   Because it is derived from fruits rich in antioxidants, tartaric acid is an excellent source of antioxidants for your skin. This is the same reason why the antioxidant properties of the grape content in wine are praised. Antioxidants help to protect your skin from damage caused by free radicals and environmental aggressors such as UV rays, pollution, etc. They help to prevent and reduce signs of aging caused by free radicals.

3. It enhances the absorption of other active ingredients.

   If you suffer from skin conditions such as keratosis pilaris, or if your skin simply needs soothing, tartaric acid can help. It has keratolytic properties, which means it helps to dissolve scales or tougher layers of skin. This enhances the effectiveness of other treatments by allowing them to be better absorbed by the skin's surface.

4. Tartaric acid also has moisturizing properties.

   Tartaric acid is broken down into tartaramides when it penetrates the epidermis. These molecules mimic the ceramides found naturally in the skin that help maintain skin hydration. Tartaramides are believed to help protect the skin's lipid matrix and bind moisture to your skin, which can reduce dryness and sensitivity.

Our peeling mask (88% natural origin ingredients)is composed of an exfoliating complex (4 AHA + 1 PHA). This concentrated gel mask eliminates dead cells to unclog pores and refine skin texture. It is applied twice a week, in the evening only. This exfoliating treatment is recommended for tightening pores and evening out skin tone. It contains tartaric acid derived from tamarind, glycolic acid, mandelic acid, and gluconolactone (10%). The high concentration of AHA + PHA in this mask promotes the renewal of the skin surface. The skin is softer, smoother, and brighter. Over the long term, the presence of blackheads is reduced and the diameter of the pores is diminished.
