Can glycolic acid dry out the skin?

Often used in peels, glycolic acid is a fruit acid known for its exfoliating virtues. Indeed, it has the ability to detach dead skin on the surface and thus stimulate the renewal of epidermal cells. Glycolic acid is present in many cosmetic product formulas at a concentration between 4 and 10%: serum, cream, tonic lotion, shower gel, etc...

However, glycolic acid can sometimes be poorly tolerated, particularly on atopic and/or very dry skin. Indeed, it stands out from other A.H.A.s such as lactic acid due to its powerful keratolytic activity and its small size which allows it to penetrate the skin deeply.

As it penetrates deeply into the various layers of the skin and stimulates cellular renewal, glycolic acid often dries out the skin.

Nevertheless, it is important to clarify that the effects of this active ingredient are highly variable and depend on its concentration, the pH of the product, and the application time. That's why it is crucial to always thoroughly read the instructions before any application.

Thus, it is likely and normal to experience slight tingling and a mild warming sensation, and to see redness appear following the application of cosmetics containing glycolic acid and/or some flaking (peeling skin). However, depending on your skin's tolerance level, these symptoms may intensify and may even be accompanied by erythema, burning sensations, tightness, itching, and facial swelling, and hyperpigmentation. In rare cases, hypopigmentation, persistent erythema, and a breakout of spots have been reported. Upon the onset of such side effects, immediately cease using the product and consider thoroughly rinsing your face with water.

At Typology, we advise against its use onvery dry, sensitive and reactive skin, as well as for individuals suffering from an inflammatory skin condition (eczema, rosacea, herpes, etc…). It is also recommended to avoid using it in pregnant women. Indeed, it is responsible for vascular disorders related to hormonal changes, resulting in congestive flare-ups on the face: the skin reddens more easily and becomes more sensitive.

Applying a product rich in hydrating active ingredients (hyaluronic acid, aloe vera, polyglutamic acid...) is an excellent way to limit skin dryness following the application of glycolic acid treatments.

We advise you to apply the moisturising treatment after the one with glycolic acid, preferably in the evening as glycolic acid is a photosensitising substance (it increases the skin's sensitivity to the sun's UV rays).

For instance, during your evening beauty routine,night, for a smooth and even complexion, apply 3 to 4 drops of ourglycolic acid serum to the face. Wait a few minutes then apply ourplumping serumwith hyaluronic acid and/or ourface moisturising cream minimalist with 9 ingredients to rehydrate your skin.
