On whether it is appropriate to use glycolic acid during the day
The method of modern skin care, glycolic acid has attracted much attention. However, many people have doubts, can glycolic acid be used during the day?

Glycolic acid belongs to the fruit acid category and has the function of rejuvenating the skin. It can exfoliate, make the skin smooth and delicate, and promote collagen regeneration, help reduce fine lines and brighten the complexion.

However, there are real concerns about its use during the day. Glycolic acid thins the stratum corneum of the skin, causing the skin to weaken its defense against ultraviolet rays. The ultraviolet rays are strong in the daytime sun. After using glycolic acid, the skin is more prone to sunburn, tanning, or even photoaging, increasing the risk of pigmentation and wrinkles.

Therefore, if glycolic acid is used during the day, protection is indispensable. A high multiple sunscreen must be applied to block ultraviolet rays. And when going out, it is advisable to hold an umbrella, wear a hat, wear long-sleeved clothing, etc., for multiple protections.

Even with protection, it is still difficult to avoid risks. Therefore, if the skin is sensitive, or the environment where the sun is strong, it is not a good strategy to use glycolic acid during the day. It can be used during skin care at night. There is no worry about ultraviolet rays at night. Glycolic acid can better exert its effect and repair the skin during sleep.

In short, whether glycolic acid can be used during the day depends on the individual skin type and the environment. Do not use it rashly, causing skin damage.
