Tartaric Acid: Are there beneficial combinations of active ingredients?

Also known by the names oftartaric acid and 2,3-dihydroxysuccinic acid, thetartaric acid appears as a white and crystalline powder. As its name suggests, it comes from "acidic" fruits such as grapes and tamarinds. This dicarboxylic acid is derived from succinic acid. In the 18th century, it was first isolated from grapes by Carl Wilhem SCHEEL, a Swedish apothecary.

It has a brightening effect and enhances the skin's luminosity. It acts on accelerating cell renewal as well as stimulating the synthesis of collagen and elastin. Thanks to its astringent and keratolytic virtues, the tartaric acid is commonly used in skincare.

• To the other exfoliating AHAs.

  Tartaric acid is typically used at concentrations ranging from 1 to 10%, often in conjunction with other alpha-hydroxy acids (citric, lactic, glycolic, malic...) within the same product. It can also be beneficial to apply several treatments each containing a single type of AHA. As a reminder, AHAs are keratin modulators. In other words, they normalise keratinisation by accelerating the formation of new cells, while promoting desquamation (synonymous with exfoliation). The combination of tartaric acid with these other AHAs allows for the following benefits:

  • Atténuer l’apparence des rides et des ridules ;

  • Favoriser l’hydratation de la peau ;

  • Éclaircir le teint ;

  • Diminuer l’intensité des taches pigmentaires.

  Therefore, combining AHA's together allows for a complementary action and greater effectiveness. However, be cautious, these combinations of different AHA's are not suitable for all skin types.They are strongly discouraged for sensitive skin and/or skin with conditions such as psoriasis or eczema.

• Regarding certain hydrating active ingredients.

  Alpha-hydroxy acids (AHA), such as tartaric acid, serve to exfoliate the skin to unclog pores, remove dead cells and restore radiance. However, they can slightly dehydrate the epidermis. Therefore, it is recommended to use a treatment based onhyaluronic acid or even polyglutamic acid to keep the skin well hydrated.
