On the application of glycolic acid before laser hair removal

In recent times, laser hair removal has become more and more popular, and there are many people who seek beauty. However, there are many taboos before surgery, which are related to effectiveness and safety, and cannot be ignored. Glycolic acid is a commonly used acid in skin care, and its application before laser hair removal is quite noteworthy.

Glycolic acid has unique properties, can exfoliate, smooth pores, and promote skin metabolism. However, it is used before laser hair removal, with both advantages and disadvantages.

If glycolic acid is used before surgery, it can loosen and shed the keratin on the surface of the skin, making the skin texture more delicate and smooth. And it can improve the smoothness of the hair follicle opening, make the laser energy more accessible to the hair follicle, enhance the damage effect on the hair follicle, and theoretically improve the effect of laser hair removal.

However, glycolic acid is also irritating. If used improperly before surgery, it will cause excessive exfoliation of the skin, thinning of the stratum corneum, and reduced skin defense. At this time, laser hair removal will make the skin more susceptible to laser heat damage, causing adverse reactions such as erythema, swelling, blisters, and even the risk of pigmentation or scarring. Therefore, the use of glycolic acid before surgery must be done with caution.

The operator should carefully observe the skin type of the surgeon. If it is a tolerant skin, glycolic acid can be used moderately before surgery, but the concentration and frequency should be strictly controlled. For example, use low-concentration glycolic acid preparations once to twice a week for a period of several weeks to make the skin gradually comfortable. And after each use, you need to take care of the skin to prevent it from drying and damage.

If it is sensitive skin, use glycolic acid with caution. Or try it before a small area of skin to see if there is any discomfort. If there is no abnormality, use it in a small range and at a low frequency. In case of tingling, itching, redness, etc., stop using it immediately.

In general, glycolic acid can be used as a sharp tool or a blunt blade before laser hair removal. Only by choosing carefully and using it scientifically according to individual skin type can we avoid harm and achieve safe and satisfactory hair removal results.
