On the effect of underarm dullness and glycolic acid toner
Husband's underarm dullness has plagued everyone for a long time. Looking at today's skin care techniques, glycolic acid toner may have a miraculous effect on underarm dullness.

Glycolic acid has unique properties. It can gently exfoliate the underarm skin, causing the old exfoliation of the underarm skin to fall off and regenerate. When the stratum corneum is gone, the surface of the skin is flat and the color is gradually uniform. And glycolic acid can promote the metabolism of the skin and speed up the rate of cell renewal. The original dull cells are replaced faster, and the new cells have a brighter state, and the underarm dullness is improved.

And glycolic acid toner is also beneficial for moisturizing the skin. It can adjust the balance of water and oil in the skin, avoid clogging pores due to unbalanced oil secretion, and then exacerbate dullness. Moderate moisturizing makes the skin hydrated and full, with self-generated luster, and the appearance of underarm dullness is also reduced.

When using glycolic acid toner, it should be based on the characteristics of the skin. If the skin is sensitive, it is recommended to try it before a small area of skin to see if it is uncomfortable. And the frequency of use should also be moderate and not excessive, so as not to damage the skin barrier.

In conclusion, the improvement of glycolic acid toner in underarm dullness can be done. However, those who use it should be cautious, according to their own skin conditions, and use it reasonably to achieve the desired effect, and also to moisturize and shine the underarm skin.
