On the effect of glycolic acid on underarm whitening
The underarm skin tone of the husband is dull, and everyone often suffers. Today, the use of glycolic acid in underarm whitening is quite a concern of the world.

Glycolic acid has unique properties. Its molecules are tiny and can quickly penetrate the surface of the skin and penetrate deep into the stratum corneum. The stratum corneum is also the barrier of the skin, but it accumulates aging keratin for a long time, often causing uneven skin tone, especially under the armpits. Glycolic acid can loosen the connection between them, causing the aging keratin to fall off naturally, making the skin surface renewed and initially shiny.

Furthermore, glycolic acid can start the process of skin metabolism. Metabolist, the key to skin vitality. When the metabolism is smooth, melanin produced by melanocytes can be transported and decomposed in time. In the armpits, if melanin accumulates, it will be dark; after glycolic acid promotes metabolism, melanin is difficult to gather, and the skin tone will gradually brighten.

And glycolic acid can increase skin hydration. Water is the spirit of the skin, and hydration makes the skin full and bright. Underarm skin is hydrated, with good light reflection, and it is also visually fair.

When using glycolic acid in the armpits, you also need to be cautious. Underarm skin is delicate, and glycolic acid is irritating to a certain extent. When using for the first time, it is appropriate to apply a small amount of low-concentration products to observe the skin's reaction. If there is any discomfort, such as tingling or redness, stop using it immediately.

In summary, glycolic acid is indeed useful for underarm whitening. However, it must be used according to the characteristics of the skin and with caution, in order to obtain its benefits and avoid its harm, and achieve the wish of underarm whitening.
