People often doubt the use of ordinary glycolic acid on the face. Glycolic acid is a type of fruit acid, which has the power of rejuvenating the skin, can exfoliate, promote the metabolism of the skin, make the skin smooth and tender, and have a uniform color.

However, its nature is strong, and it must be used with caution when applying it to the face. If the skin is sensitive and weak, or those who use fruit acids for the first time, use it rashly, for fear of skin discomfort, such as redness, itching, desquamation, etc.

Therefore, if you want to use ordinary glycolic acid on the face, you should first judge your own skin. Those with thick, tough skin and strong tolerance may try. When starting to use, it is advisable to apply a small amount of thin coating at a low concentration to observe the reaction of the skin. And it should not be used frequently. Use it at the beginning or every other day, until the skin gets used to it, and then increase the frequency.

When using it, you should also pay attention to protection. After daytime use, you must especially take strict sun protection. Because glycolic acid makes the skin more sensitive to light, it is easy to cause sunburn and pigmentation. If the skin is obviously uncomfortable during use, stop using it immediately and seek medical consultation if necessary. In short, using ordinary glycolic acid on the face, with prudence as the foundation, can reap its benefits and avoid its harm.
