Whether glycolic acid can dilute dark spots
There are skin care methods in the world, and glycolic acid is often used. However, there are different opinions on its effect on diluting dark spots.

Or glycolic acid has the power to dilute dark spots. Glycolic acid is a fruit acid, its molecules are tiny and can quickly penetrate the surface of the skin. It can promote the renewal of the stratum corneum, make the aging keratin shed, and make the skin new. The formation of dark spots is often due to the accumulation of keratin and pigmentation. Glycolic acid not only promotes the renewal of the keratin, but also reduces the accumulation of pigment on the surface, so the color of dark spots gradually fades. And it can stimulate the synthesis of collagen, make the skin firmer, and restore luster, and the dark spots will not appear.

There is also doubt. For those with sensitive skin, use glycolic acid for fear of discomfort. Because it is irritating, or causes skin redness, itching, and even allergies. The causes of dark spots are complex, or due to genetics, endocrine, sun exposure, etc. Glycolic acid alone is difficult to remove the root cause. If you do not avoid sun exposure, adjust work and rest, and manage endocrine, use glycolic acid, dark spots or return, the effect of fading is difficult to last.

In summary, glycolic acid is used to dilute dark spots, or has its effect, but your mileage may vary. Those who use it should review their own skin conditions, weigh the pros and cons, or match other methods to achieve the best effect and protect the beauty of the skin.
