On the feasibility of using glycolic acid overnight
For those with glycolic acid, many people doubt whether it can be retained on the skin overnight in the way of skin care. The nature of covering the skin varies, and this question is related to the user's immediate experience and effect.

Those with delicate and delicate skin have thin stratum corneum and weak tolerance. Glycolic acid has the ability to exfoliate and rejuvenate the skin. However, if such skin rashly uses glycolic acid overnight, the skin may be overwhelmed by its strength, causing redness, tingling, and itching. For example, if it is a delicate flower in spring, it will be damaged by the wind and rain.

For those with rough skin, thick stratum corneum and strong tolerance, glycolic acid overnight may be a beneficial move. It can penetrate the skin deeply, smooth its pores, remove its old keratin, and make the skin glow. It is like a jade that has been covered in dust for a long time. After wiping, it will reproduce a warm and radiant luster.

However, even those with good tolerance should be careful when using glycolic acid for the first time. You can try it on a small scale first, such as behind the ear, in the jaw and other hidden places, to see if the skin is uncomfortable. If there is no abnormality, then gradually expand the scope and duration of use. And the frequency of use should gradually increase, not overnight.

Glycolic acid is easy to decompose when exposed to light, and when used overnight, the skin will be exposed to it for a long time, or the risk of irritation will increase. Therefore, when using at night, make sure that the lying area is clean and free of excessive dust debris, and when you wake up the next morning, be sure to wash with gentle cleansing products, then follow the order of daily skin care, and apply sunscreen to prevent the skin from becoming more sensitive to light due to the action of glycolic acid.

To sum up, whether glycolic acid can be used overnight depends on the characteristics of the individual skin and the method of use. If you act prudently, you can achieve the effect of skin improvement; if you act rashly, you may risk skin damage. Users should carefully observe their own skin and use it with discretion.
