There are various opinions on the effect of glycolic acid skin change when
glycolic acid skin change takes effect, and the time of effect also varies according to many conditions.
Looking at the concentration of glycolic acid used, if the concentration is quite low, about 20%, such a mild agent may need to be applied multiple times to see its effect. At the beginning of use, the skin only feels a slight change, or the roughness of the skin surface gradually slows down, and the color is slightly uniform. Such subtle signs, or after several uses, can be observed after two or three weeks.
However, if the concentration of glycolic acid is increased to 50% or even higher, the effect will be rapid. After one application, the skin often experiences a short-term red heat, which is the appearance of the medicinal power stimulating the surface. After three to five days, it can be seen that the old keratin is gradually exfoliating, the skin is rejuvenated, the fine lines are light, and the skin tone is bright and moist. This is because high concentrations of glycolic acid can quickly loosen the connection between the keratin and promote its metabolism.
Furthermore, people's skin types are different, which is also related to the time of effect. Dry skin, its texture is delicate, and its tolerance to glycolic acid is slightly weaker, so the onset is slow, and it needs to be gradual, starting from low concentration and recuperating after menstruation to get good effect; oily skin, thick sebum, strong tolerance, high concentration glycolic acid is applied, or the effect of oil convergence and pores shrinking will be seen within a week.
And daily maintenance and life habits, also affect the effect of glycolic acid skin change. If you take care of your skin after a skin change, avoid sun exposure, often moisturize it with moisturizing products, eat a light diet, and work and rest in an orderly manner, the effect will be fast and good; on the contrary, if you are exposed to the hot sun, indulge in alcohol, work and rest are impermanent, skin repair is blocked, and the effect will be delayed.
In short, when glycolic acid skin change takes effect, it cannot be generalized. It is necessary to consider various factors such as concentration, skin type, and maintenance, and be careful to achieve the beauty of skin rejuvenation.
