Differentiation of Glycolic Acid and Retinol
Fuglycolic acid and retinol are both commonly used ingredients in skin care, but their properties and effects are very different.

Glycolic acid belongs to the fruit acid family, with small molecules, which can run smoothly through the skin, dissolve the bond between the cuticles, make the old cuticles fall off, and the skin is tender and smooth. And it can promote collagen hyperplasia in the dermis, lighten lines and rejuvenate, and increase skin hydration, making the skin radiant and radiant. Its effect is rapid, but those with sensitive skin may feel uncomfortable for the first time, such as tingling and redness.

Retinol is a derivative of vitamin A. It can regulate keratin metabolism, prevent hair follicle blockage, and has healing power for acne. It can also stimulate cell renewal, promote collagen regeneration, reduce wrinkles and resist aging. Its effect is gradual, and it needs to be slowly adapted to the skin. Early use often causes peeling, dryness, and is sensitive to light. Strict sun protection is required for daytime use.

Glycolic acid is water-soluble, has a shallow effect, and quickly reveals skin luster; retinol is lipid-soluble, can enter the deep layers of the skin, and has a long-term anti-aging effect. In comparison, glycolic acid should be used for those with thick keratin and oily skin for quick-acting; retinol is suitable for those with mature age and dry skin for long-lasting anti-aging.

When using it, it must depend on its own skin nature. Try it on a small scale first, no discomfort, and then gradually expand it. And from less to more, slowly increase the frequency, so as to keep the skin safe and receive the effect of skin care. Be careful, so that the beautiful skin can be permanent.
