On the use of glycolic acid on the feet
Nowadays, some people doubt whether glycolic acid can be applied to the feet? Glycolic acid belongs to the class of fruit acids and has many wonders. It can exfoliate, make the old stratum corneum of the foot skin gradually detach, and make the skin rejuvenated. If it is pristine, it will regain its luster. And it can promote collagen production, making the foot skin firm and elastic, as if it were new.

It is also necessary to pay attention when applying it to the feet. The skin on the feet may be thick or rough, which is different from others. When using it for the first time, it is necessary to check the response of the skin. You can first take a little glycolic acid products and apply them to the small part of the skin of the foot. After a few hours, observe whether it has redness, itching, tingling and other discomfort. If so, it is not advisable to use it because the skin is sensitive to it.

And glycolic acid has a certain irritation, and the concentration should not be high. Glycolic acid products in different concentrations in the market should be selected with caution. If the concentration is too high, although it seems to be effective for a while, it is easy to hurt the skin, cause redness, swelling, molting, and even ulceration, and regret it is too late.

The frequency of use should also be controlled. Do not seek quick effect and use it frequently. It is often advisable to use it once or twice a week, and it can be increased slightly when the skin adapts. After using it again, it is necessary to protect against the sun. Because the skin has weak resistance to ultraviolet rays after the action of glycolic acid, if exposed to the sun, it is easy to cause pigmentation and damage the appearance of the skin.

In short, using glycolic acid on the feet is like holding a double-edged sword. Use it properly, can make the skin of the feet beautiful and healthy; use it improperly, it will harm the skin. Users should observe the condition of the skin and follow the law to get its benefits and avoid its harm.
