On the feasibility of using glycolic acid twice a day

Those who use glycolic acid twice a day have attracted much attention in the field of skin care. However, the feasibility of using it twice a day needs to be explored in detail.

The state of the skin is different. Those with delicate, smooth and strong tolerance may try the method of using glycolic acid twice a day. The skin is solid and can be affected by the effect of glycolic acid without discomfort. However, those with delicate and sensitive skin may use it twice a day rashly for fear of erythema, itching, and tingling. The skin barrier of this generation is fragile, and the stimulation of glycolic acid can easily cause skin injuries, such as the collapse of the city wall, to defend against discomfort.

And the effect of glycolic acid is exfoliating and promoting skin metabolism. However, if it is done too much, twice a day, exfoliation is too much, the protective barrier of the skin is damaged, moisture is lost, the skin is prone to dryness and tightness, and many skin diseases are caused. It is necessary to use glycolic acid step by step. At the beginning, you can use it every day to observe the reaction of the skin. If the skin adapts well and there is no adverse appearance, you can increase the frequency as appropriate.

Furthermore, when using glycolic acid, protection is also essential. Special attention should be paid to sun protection during the day, because glycolic acid makes the skin more sensitive to ultraviolet rays. Without protection, it is easy to cause sunburn, tanning, or even accelerate skin aging.

In short, the use of glycolic acid twice a day is not always feasible. It should be done with caution and comprehensive protection according to personal skin characteristics to achieve the effect of skin care and avoid skin damage.
