Tartaric Acid: How to use it?

There are several types of treatments containing tartaric acid in their composition (cream, serum, mask, shampoo, hair serum...). It is most often incorporated at concentrations between 1 and 10%, alone or in combination with other alpha-hydroxy acids. It has a pH between 3.5 and 4. The use of care products containing this active ingredient should be reasonable and limited.

• It is advisable to use this active ingredient during the evening daily routine to minimise any risk of photosensitivity. Indeed, tartaric acid increases the skin's sensitivity to the sun, thus the risk of sunburn. We also recommend consistently applying a SPF cream every morning and to limit or even avoid prolonged sun exposure, as long as you are using a product containing tartaric acid and up to a week after its last application.

• In the same vein, it is preferable to apply products containing tartaric acid in autumn/winter, rather than in the summer period. However, it is still possible to start or continue applying tartaric acid solutions during sunny spells (spring and summer), provided of course that it is combined with a minimum SPF30 sun protection and as much as possible, sun exposure is avoided.

• The frequency of use depends on your skin type, skin tolerance level, as well as your needs and expectations. We advise you to start atspaced intervals, such as every other night or even every three nights, then increase the frequency after one to two weeks if your skin tolerates this active ingredient well. It is normal to temporarily feel a slight sensation of warmth, some tingling or a slight dryness of the skin during the first few days. If your skin is naturally dry or if you are applying a tartaric acid treatment for the first time, start with a treatment with a low concentration so that your skin can adjust (around 5%).

• It is recommended to apply a tartaric acid treatment onlyonce a day, at most, in order to avoid all the side effects mentioned above.

• For tartaric acid to function effectively on the skin, it is often combined with other acids such as glycolic acid, lactic acid, malic acid, citric acid, or mandelic acid. Therefore, it is not uncommon for several of these ingredients to be found in the same formulation. However, it is advised against pairing tartaric acid with another ingredient with a dermabrasive action like salicylic acid. Using two exfoliating treatments at the same time can affect the overall health of the skin. Therefore, it is important to check the composition of all treatments used during a beauty routine.

It should be noted that there are also hair care products containing tartaric acid, whose effect on the scalp is identical to that of tartaric acid on the skin. Therefore, the precautions for use are the same for hair products as they are for skin care treatments.
