The theory of fruit acid freckle removal
The effect of fruit acid on the skin has been much explored by the world, especially its freckle removal ability, which has attracted much attention.

Those with freckles are often born on the face, light brown in color, and numb in star cloth, which is annoying to all kinds of beautiful people. Among fruit acids, glycolic acid (Glycolic Acid) is a commonly used category. It is mild in nature and has a unique effect.

The freckle removal of glycolic acid is covered because it can promote the metabolism of the stratum corneum. The stratum corneum of the skin, like the tiles of a house, is stacked on top of each other. Over time, old cuticles accumulate, and the color of freckles may appear darker. Glycolic acid can loosen the connection between keratinocytes, making the old stratum corneum easy to fall off, and the new skin gradually exposed. This new skin has a uniform color, and the color of freckles may be reduced.

And glycolic acid can stimulate the collagen hyperplasia of the dermis. The dermis layer, the foundation of the skin, is rich in collagen, the skin is full and elastic. The appearance of freckles may also be due to the uneven structure and color of the local skin. Glycolic acid promotes collagen production, which can improve the microstructure of the skin and make the texture of the skin more uniform.

Use glycolic acid to remove freckles, but also need to be cautious. The skin is different, and those who are sensitive may feel uncomfortable using it. For the first time, it is recommended to try it on a small scale to observe the application of the skin. And the concentration and frequency of use should be moderate. If the concentration is high and the frequency of use is high, it may cause the skin to redness, tingle, and damage the skin.

In general, glycolic acid has a certain effect on freckle removal. However, those who use it should follow their own skin nature and be cautious. Only then can they obtain its benefits and avoid its harm, and achieve the beauty of smooth skin.
