How Glycolic Acid Works
Glycolic acid has attracted a lot of attention in the field of skin care. Its mechanism of action is quite unique and complex.

Bearing the brunt, glycolic acid has excellent exfoliation effect. The outer layer of the skin is the stratum corneum, which is formed by stacking multiple layers of keratinocytes. With the passage of time and the influence of external factors, the metabolism of keratinocytes slows down, and it is easy to accumulate, making the skin rough and dull. Glycolic acid, with its small molecular structure, can penetrate into the gap between stratum corneum cells, weaken the connection between cells, and promote the natural shedding of old keratinocytes. This process is like a spring breeze, gentle and orderly, helping the skin regain a smooth and delicate texture, such as peeling off old cocoons and revealing new skin.

Furthermore, glycolic acid can stimulate the production of collagen. Collagen is a key element for the skin to maintain elasticity and firmness. With age, the ability of collagen synthesis in the skin decreases, resulting in problems such as relaxation and wrinkles. Glycolic acid acts on the deep layers of the skin and activates fibroblasts, which are the main force for collagen synthesis. Stimulated by glycolic acid, the vitality of fibroblasts is enhanced, accelerating the synthesis and secretion of collagen. It is like injecting vitality into the skin, supporting the structure of the skin, so that the skin regains elasticity, wrinkles become lighter, and looks young and plump.

In addition, glycolic acid has the power to improve the skin's moisturizing ability. Its molecular structure contains hydroxyl groups, which are highly hydrophilic. On the surface of the skin, glycolic acid can combine with water molecules to form a moisturizing film to prevent excessive loss of skin moisture. At the same time, it can also promote the synthesis and release of the skin's own natural moisturizing factors, further strengthening the skin's moisturizing function. In this way, the skin is always hydrated, as if it were in a warm and moist environment, radiating a healthy glow.

In summary, glycolic acid in the field of skin care brings all-round care and improvement to the skin through the synergistic effect of exfoliation, stimulating collagen production and improving moisturizing ability, achieving skin rejuvenation and radiance.
