On the efficacy of 5% glycolic acid
Fuglycolic acid has attracted much attention in the way of skin care. This article focuses on 5% concentration of glycolic acid to explore its efficacy.

5% glycolic acid has unique chemical properties. Its molecules are small and can easily penetrate into the surface of the skin. Under this concentration, the main function is gentle exfoliation. On the surface of the skin, the old waste exfoliation that has accumulated for a long time hinders the skin's respiration and nutrient absorption. 5% glycolic acid can loosen the connection between keratinocytes, causing the old waste exfoliation to naturally fall off, making the skin smooth and delicate again. It feels like a new silk to the touch, and it also shines when viewed, just like a pearl being wiped back after being dusted.

Furthermore, it also has a significant effect on promoting skin metabolism. Metabolism is the key to skin vitality. 5% glycolic acid can stimulate the renewal of basal cells and accelerate the replacement rate of skin cells. Just like an endless stream of water, new cells continue to pour out, replacing senescent cells, and the overall state of the skin is improved. During this process, the skin's self-repair ability is also enhanced. Minor blemishes and dullness are gradually corrected, and the skin tone becomes uniform.

And 5% glycolic acid also helps moisturize the skin. After the stratum corneum is regularized, the skin's barrier function is optimized. It can help the skin retain moisture, just like building an embankment to store water. If there is sufficient moisture, the skin is full and elastic, and the fine lines are also reduced, just like a dry land regaining its moist and vitality.

However, with 5% glycolic acid, caution is also required. Because of its certain acidity, those with sensitive skin may feel uncomfortable for the first time. Therefore, when using it for the first time, a small amount and low frequency should be used to make the skin gradually adapt. And when using it during the day, you need to pay attention to sun protection to prevent the skin from becoming more sensitive to ultraviolet rays due to accelerated metabolism.

In summary, 5% glycolic acid is effective in improving skin texture, promoting metabolism, and enhancing moisturization. However, those who use it should use it reasonably according to their own skin conditions in order to enjoy its benefits, avoid its possible harm, and achieve the ideal skin care purpose.
