On the method of combining glycolic acid toner with lactic acid
for skin care, glycolic acid toner and lactic acid have attracted much attention in recent years. Both belong to fruit acids, but their properties and uses are quite interesting.
Glycolic acid has tiny molecules, penetrates the skin quickly and strongly. It can penetrate deep into the stratum corneum, loosen the adhesion between them, make old keratin fall off, rejuvenate the skin, make the skin smooth and shiny, and also has an effect on improving dull complexion and light spots.
Compared with lactic acid, the molecule is slightly larger and the effect is mild. In addition to promoting keratin renewal, it has more moisturizing power, can increase the moisture content of the skin, and make the skin soft.
As to whether the two can be used together, it is necessary to be cautious. If the skin tolerates well, the combination of the two may have a synergistic effect. Glycolic acid first starts exfoliation, followed by moisturizing and further gentle metabolism of lactic acid, which may be of great benefit to improving skin quality.
However, for those with sensitive skin, the combination is easy to cause irritation. The strong penetration of glycolic acid and lactic acid superimpose, or make the skin reddish, itchy, and tingling. Therefore, before using it together, do a local skin test. Take a little mixture and apply it behind the ear or on the inside of the forearm. When used together, the concentration should be gradually increased. For the first use, choose low-concentration glycolic acid toner and lactic acid products. When the skin adapts, increase the concentration. At the same time, pay attention to the frequency. Start once or twice a week, then gradually increase, but not too often, so as not to damage the skin barrier.
In short, when glycolic acid toner is used in combination with lactic acid, opportunities and challenges coexist. According to the characteristics of the skin, if you follow it, you are expected to get good skin care results.
