"On the Prohibition of the Use of Glycolic Acid Toner (The Ordinary) "

Glycolic acid toner, the product of "The Ordinary", has significant effect, and it is also advisable to use it. Now list the things that cannot be used with it, for your reference.

First, alkali substances must not be used with glycolic acid toner. For glycolic acid, when it encounters alkali, it will cause a neutralizing reaction, which will not only damage the effect of the toner, but also hurt the skin. The skin is delicate, and the balance of acid and alkali is very important. Using the two together, such as using water to replenish fire, will only increase the worry.

Second, high-concentration vitamin C products should also be avoided. Glycolic acid and high-concentration vitamin C are applied to the skin together, or cause skin irritation to intensify. Both have certain activity. When used in combination, the force is too strong, the skin is unbearable, and the light cases are redness and itching, and severe cases may cause inflammation.

Third, matte products should not be used with glycolic acid toner at the same time. Glycolic acid has the ability to exfoliate, and matte products also have this effect. When used in the same way, excessive exfoliation, skin barrier damage, and resistance to external forces are greatly reduced. It is easy to be invaded by external evil, such as dryness and allergies, which follow one after another.

Fourth, strong whitening products should also be staggered with glycolic acid toner. Powerful whitening products contain many special ingredients, which are used in combination with glycolic acid, or interfere with the normal metabolism of the skin, affect the health of the skin, and fail to whiten, resulting in skin problems.

Use glycolic acid toner, when it is known that it cannot be used in combination with alkalis, high-concentration vitamin C products, scrubs and strong whitening products. In this way, it is beneficial to avoid harm, so that the skin can be protected and radiated. When you use it, be careful.
