Hidrotelial Nourishing Repairing Hand Cream 75ml

Glycolic acid is an alpha hydroxy acid (AHA) obtained from sugar cane. Its molecules are so small that they penetrate the deeper layers of the skin, stimulating collagen synthesis and moisturising substances such as hyaluronic acid. But it is mainly known for its action to improve skin micro-relief (skin texture and luminosity), as it can exfoliate at a more superficial level (on the stratum corneum).

In cosmetic products, depending on the concentration, as well as the combination with other ingredients, a moisturising effect may predominate (the lower the concentration of glycolic acid) or exfoliating effect (at higher concentrations). This concentration range can go from 4% to 20%. Choosing a type of cosmetic formula with glycolic acid will depend on the desired objective and skin sensitivity. For example, higher concentrations are usually found in intensive products for weekly application: with a deeper effect, in treatments to combat hyperpigmentation, wrinkles and/or comedones. They will release more superficial corneocytes (cells), which will be eliminated and promote skin renewal.

When starting to use it or looking for better tolerance, daily use products with a lower concentration will provide renewal, brightness and hydration to the skin. In addition to all these properties, it can also improve acne lesions, blackheads and blemishes.

As in any routine, but especially when using this type of renewing ingredients, daily sun protection is essential. I do not recommend starting to use glycolic acid with other acidic or irritating ingredients. After application, a slight stinging sensation may appear, which quickly subsides and will subside progressively. If the discomfort persists, it means that the product is not suitable or that your skin cannot tolerate it. It is important to receive good dermo-cosmetic advice to find a routine adapted to your skin type and your needs.
