On the efficacy of glycolic acid
Glycolic acid has outstanding functions in the field of skin care. Its first achievement is to rejuvenate the skin. Glycolic acid can loosen the adhesion between keratinocytes, promote the orderly shedding of the old stratum corneum, and then allow new skin cells to appear on the surface. This process is like spring and everything is renewed. The surface of the skin is purified, showing a delicate and smooth state, and it is radiant, like a pearl wiped back after being dusty, shining as before.

Furthermore, the improvement of glycolic acid on the texture of the skin is quite effective. As the years pass, the texture of the skin may gradually become rough and disordered for various reasons. Glycolic acid can stimulate the production of collagen in the skin due to its unique chemical properties. Collagen is the "steel" structure of the skin, and its content is abundant or not, which affects the firmness and elasticity of the skin. Glycolic acid helps collagen regenerate, like building a more solid support system for the skin, so that the skin texture can be reshaped, becoming firmer and smoother, and fine lines and wrinkles will also be lightened, just like the traces of time have been quietly smoothed.

In addition, glycolic acid also has excellent performance on the moisturizing level of the skin. Its molecular structure is special, hydrophilic, and can absorb and retain skin moisture. It is like creating a miniature "reservoir" for the skin, so that the skin is always in a state of hydration and fullness. In this way, the skin not only feels soft to the touch, but also has a smoother metabolism due to sufficient moisture, and many skin problems can be easily solved.

Glycolic acid can also play a role in the regulation of skin pigmentation. It can inhibit the activity of tyrosinase, which plays a key role in the production of melanin. The inhibition of its activity by glycolic acid is like strangling the throat of melanin production, reducing the synthesis and deposition of melanin. Over time, the skin's pigmentation and dullness can be improved, and the skin tone tends to be even and shiny, just like the warm sun in spring to dispel the haze, and the skin regains its white luster.

To sum up, glycolic acid is a multi-pronged approach to skin care, from rejuvenation and firming to moisturizing and fading spots. It is a good agent for skin care. For those who pursue skin beauty, it opens a door to bright skin.
