"On the Comparison between Glycolic Acid and Lactic Acid"

There are skin care diacids, called glycolic acid and lactic acid, which are all good products for rejuvenating the skin. However, their properties and uses have similarities and differences, which cannot be ignored.

Glycolic acid has small molecules and strong penetrating ability. It can quickly enter the deep layers of the skin, exfoliate adhesions, promote exfoliation and renewal, and remove the old and new texture on the surface of the skin, so it can significantly brighten the complexion and smooth the skin. For beginners, or the skin feels slightly prickly, this is a sign of its powerful effect, and sensitive skin should be especially careful.

Lactic acid is slightly milder in nature and slightly larger in molecule. It is quite good at moisturizing, it can attract water into the skin and make the skin moist. At the same time, it can also slow down the metabolism of keratin and improve roughness, but its effect is slower than that of glycolic acid. The beauty of lactic acid is that sensitive skin can also receive it, although the effect is slow and stable.

If you want quick-acting brightening and strong skin tolerance, glycolic acid is the best choice; if the skin is delicate, you want to moisturize and slow down the keratin, lactic acid is more suitable. Those who use it should review their own skin type and measure its advantages and disadvantages in order to obtain the good effect of skin care and get the skin's transformation.
