On the appropriate frequency of weekly use of glycolic acid
Those who use glycolic acid have a lot of merit in skin care. However, the frequency of its use is related to the effect and skin comfort, and should not be careless.

For those who use glycolic acid for the first time, the skin is not used to it, so it should be slowed down. In the first week, it is appropriate to use it every three days, that is, about twice a week. When it is necessary to cover the skin, it should be used to deal with this new product. If it is used frequently, it may cause discomfort, such as redness and itching.

When the skin is gradually adapted, it can be increased to once every two days from the next week, up to three times a week. This frequency allows glycolic acid to gradually develop its ability, revitalize the skin, exfoliate, promote metabolism, and make the skin delicate and shiny.

If the skin is well tolerated and there are no adverse reactions after use, it is not necessary to use glycolic acid four times a week. Even so, you should pay close attention to the state of the skin.

As for extremely dry or sensitive skin, you should be especially cautious when using glycolic acid. At the beginning, once a week, check the skin's response. If there is no abnormality, you can increase the frequency slightly, but it should not be too dense to prevent skin damage.

In general, glycolic acid is used frequently every week, and your mileage may vary. When based on the tolerance of the skin, step by step, you can take the benefits of skin care and avoid its harm.
