On the stimulating effect of glycolic acid on collagen

The beauty of a husband's skin depends on firmness and elasticity. The key to this is collagen. In recent years, glycolic acid has emerged in the way of skin care, and its stimulating effect on collagen has attracted much attention.

Glycolic acid is a type of fruit acid, with tiny molecules that can travel unimpeded and penetrate into the deep layers of the skin. Its primary function is to accelerate the metabolism of stratum corneum cells. For stratum corneum, such as the outer screen of the skin, if the old cells accumulate too thick, the skin will be dull and rough. Glycolic acid promotes the rapid renewal of keratinocytes, making the surface of the skin look brand new, and laying a smooth path for subsequent nutrient absorption.

As for its stimulation of collagen, the mechanism is subtle. In the skin, fibroblasts are the main force for the synthesis of collagen. Glycolic acid can activate fibroblasts, increase their vitality, and then synthesize more collagen. Another study has shown that glycolic acid can up-regulate the expression of related genes, which are like the book of instructions, guiding fibroblasts to synthesize collagen. In this way, the production of collagen can be increased, the support structure of the skin can be strengthened, wrinkles will gradually disappear, slack will improve, and it will look firmer and younger.

However, the use of glycolic acid should also be cautious. Because of its certain acidity, high concentration or improper use, it is easy to cause skin discomfort, such as tingling, redness, etc. Therefore, when using it for the first time, it is recommended to start with a low concentration, step by step, and do a good job of skin moisturizing and sun protection.

In summary, glycolic acid does have a good effect on stimulating collagen production and improving skin condition, but if it can be used reasonably, it can achieve twice the result with half the effort and achieve the beauty of the skin.
