All Typology skincare products containing glycolic acid.

The primary actions of glycolic acid.

Often referred to as fruit acid, glycolic acid is a potent active ingredient that is found in many beauty products: from peels to masks, through serums or targeted night creams such as purifying treatments for oily skin, brightening or even anti-wrinkle, body care, shampoos and conditioners, and even toners and cleansing lotions.
Being part of the family of alpha-hydroxy acids (A.H.A.), glycolic acid is derived from fruit sugars (beet, grape, sugarcane, pineapple, etc...). Its low molecular weight (M = 76.05 g/mol) gives it a great ability to penetrate into the deep layers of the skin. On the market, the percentages of A.H.A. in individual products fluctuate between 4% and 10%. Therefore, it is suitable for all skin types, provided that a product suitable for one's skin is chosen. Beyond that, the treatment should be performed by a doctor.

This molecule is particularly valued for its exfoliating virtues. Indeed, glycolic acid reacts by simple contact and without friction with the stratum corneum by weakening the lipid bonds that connect the corneocytes to each other, causing an acceleration of the natural desquamation process and the effective removal of impurities, thus revealing a smoother, more toned, and younger skin underneath. Indeed, this results in a significant improvement in the texture and appearance of the epidermis, due to a stimulation of cellular regeneration and cutaneous microcirculation. The complexion is smoothed and brightened, the skin is purified (regulation of sebum secretion), the size of the pores is refined, and skin irregularities are diminished (acne scars, etc...).

Other effects are also documented: this acid also helps to reduce pigmentation spots by inhibiting the overproduction of melanin, as well as to restore firmness and hydration to the skin, and diminish the appearance of wrinkles and fine lines by stimulating the synthesis of collagen and elastin, which are responsible for skin tone, and hyaluronic acid. These benefits most often depend on the dosages and other active ingredients found in combination in cosmetic products.

When should glycolic acid be used?

Most skin types can benefit from the use of a glycolic acid-based skincare product. It is particularly suitable for dry, normal, combination to oily skin, skin prone to imperfections (enlarged pores, pimples, blackheads), dull, hyperpigmented, rough, and mature skin. However, glycolic acid may not be favorable for some individuals. If you have sensitive skin, these treatments are probably not for you. We strongly advise you to consult a dermatologist before trying it. Indeed, it can trigger allergic reactions as well as irritations. Similarly, individuals with darker skin may have a risk of pigmentation with the use of glycolic acid.

Glycolic acid seamlessly integrates into formulas designed for combination to oily skin as a seborrhea regulator, thus preventing new acne outbreaks, pore blockage, and the formation of blackheads. For dry skin, this ingredient is recommended to increase skin hydration by contributing to the synthesis of hyaluronic acid. Glycolic acid can even help skin with a lot of pigmentation (sunspots, melasma, acne marks), by making them less visible and evening out the complexion. It is also reputed to help skin that appears tired and dull look more radiant, fresher, brighter, and younger. On mature skin, treatments containing glycolic acid are appreciated for their brightening properties, their tightening effect, and their ability to reduce the appearance of wrinkles and fine lines. Moreover, by removing the outer layer of dead cells and promoting cell renewal, it facilitates the absorption of other skincare products into the skin.

How to incorporate glycolic acid into a skincare routine?

Although glycolic acid possesses a moisturizing property, cosmetic products containing this active ingredient are primarily exfoliants. Therefore, it's crucial to hydrate your skin when using fruit acids. Indeed, as an exfoliant, glycolic acid poses a risk of drying out the skin. To combat this effect, apply a moisturizing cream suitable for your skin type after using such treatments.

Little Extra : Our exfoliating serum with 10% glycolic acid also contains ingredients with soothing, anti-irritating, anti-inflammatory, and repairing properties, such as bisabolol and chamomile extract. Our exfoliating toner with 8% glycolic acid contains vegetable glycerin, known for its moisturizing properties, thus potentially reducing the occurrence of skin inflammation and irritation, just like our exfoliating shower gel.

Furthermore, by exfoliating, you thin the stratum corneum. The skin then becomes more exposed, more vulnerable, and more sensitive. Therefore, the application of glycolic acid cosmetic products in the evening is recommended. This gives the skin ample time to regenerate during sleep. Indeed, it is during this period that the peak of skin regeneration is at its highest. Additionally, it is advised to protect the skin from UV rays, regardless of the season, with a sunscreen (minimum SPF 30) during the day and, if possible, to avoid prolonged exposure for a few weeks. If not protected, the skin will redden more quickly and the risk of sunburn will be greater.

To achieve smoother, healthier, and more radiant skin, start by removing your makeup and then cleanse your face. Also, ensure your skin is properly dried: applying on wet skin will be less effective and less well-tolerated, as the presence of water makes the acid more irritating. If you choose our glycolic acid face exfoliating serum , spread between 3 and 4 drops (the equivalent of a small pea) on your face during your evening beauty routine. Gently massage for a few moments to allow the active ingredients to penetrate deep into the skin. This treatment does not need to be rinsed off. When applying, be sure to avoid the eye contour! The same goes for our peeling mask. It combines the action of four A.H.A.s and one P.H.A. to work at different depths of the epidermis and eliminate dead cells. This gel mask can be used once or twice a week, in the evening only.

Regarding the exfoliating toner with glycolic acid, it can be used daily in the evening only, after your makeup removal. To do this, soak a reusable cotton pad with the exfoliating lotion, then apply it to the entire face, carefully avoiding the eye contour. There is also no need to rinse. You can then complete your skincare ritual by applying a serum and a night cream. We have developed an exfoliating night cream, based on glycolic acid. Offering a deep-cleansing action, it helps day after day to fight against the dilation of pores and the appearance of blackheads.

You will also find a exfoliating shower gel with 6% glycolic acid at Typology. Only in the evening, apply a dollop of the product to your entire body, which should be damp beforehand. There's no need to use a large amount to wash effectively. After your shower, it is recommended to apply a moisturizing treatment to complete your routine. Finally, for hair care, for example a glycolic acid shampoo, apply the product to wet hair, then massage for a few minutes before rinsing.
