Glycolic Acid

It is advised against for individuals with sensitive and reactive skin, as well as those suffering from an inflammatory skin condition (such as eczema, rosacea, herpes, etc.) to use glycolic acid. Depending on the concentrations, pregnant women should also exercise caution.

In some individuals, the glycolic acid can cause a temporary phase of worsening pimples. However, in the long run, it generally helps to reduce blemishes.

In general, glycolic acid can be combined with any active ingredient. However, for sensitive skin, it is preferable to use both skincare products containing glycolic acid and products based on retinoids, benzoyl peroxide, or other exfoliating acids.

In cosmetics, glycolic acid is typically incorporated at rates between 4 and 10%. In professional settings or with dermatologists, it can be used at higher concentrations, maximizing its effectiveness but also its potential for irritation.

Daily use of glycolic acid is possible for some individuals, but it is recommended to start with an application every 2 - 3 days to avoid irritation, then adjust according to the tolerance of one's skin.

The glycolic acid operates on several levels to reduce various pigmentation spots, including sun spots.
