On the use of glycolic acid before and after shaving
Shaving is a matter of face cleanliness and is a daily practice for many people. The use of glycolic acid before and after shaving is quite elegant.

The use of glycolic acid before shaving has significant benefits. Glycolic acid has a gentle exfoliating effect and gently peels off the aging keratinocytes on the surface of the skin. In this way, the skin surface is smoother and the beard is easier to shave. When the stratum corneum of the skin is regular, the contact between the shaving tool and the skin is smoother, reducing the pulling and friction caused by rough beard and uneven skin, thereby reducing the risk of skin injury and scratches during shaving. For example, if there is a thick accumulation of keratin on the surface of the skin, the blade will easily get stuck during shaving, causing tingling; and after glycolic acid pretreatment, this situation will be greatly reduced.

However, you should also pay attention to using glycolic acid before shaving. Glycolic acid is acidic to a certain extent. If the skin is more sensitive, direct use may cause discomfort. Therefore, for sensitive skin, you need to try it on a small piece of skin first to observe whether there are any adverse reactions such as redness and itching. And the concentration should not be too high when using, and low-concentration products are appropriate to avoid excessive irritation of the skin and damage to the skin barrier.

As for the use of glycolic acid after shaving, it also has its advantages. The shaving process can cause more or less minor damage to the skin. At this time, glycolic acid can exert its functions of antibacterial and promoting skin metabolism. It can inhibit the growth of bacteria and prevent infections caused by minor wounds in the skin after shaving. At the same time, it can accelerate the renewal of skin cells and promote the rapid repair of damaged skin. For example, some people are prone to small red spots on the skin after shaving. After using glycolic acid, these small red spots often subside quickly.

But there are also points to pay attention to when using glycolic acid after shaving. Since the skin is in a relatively fragile state after shaving, if high concentrations of glycolic acid are used immediately, it may exacerbate the tingling sensation of the skin and even lead to aggravation of skin inflammation. Therefore, the skin should be slightly soothed, usually about half an hour after shaving, and the product should be gently applied with a lower concentration, and follow-up moisturizing work should be done to maintain the balance of water and oil in the skin.

In short, glycolic acid has advantages and disadvantages before and after shaving. Users should carefully choose the timing and concentration of the product according to their skin condition, so as to maximize the effect of glycolic acid and take care of skin health.
