On the Usage of Glycolic Acid
Fuglycolic Acid is quite beneficial in the way of skin care, but it also needs to be used.

To start using it, it is recommended to take a small amount first, such as the glycolic acid products produced in "The Ordinary", and apply it lightly to the skin on the wrist to see how the skin should respond. If the skin is free of itching and redness, it can be used on the face.

When applying the surface, clean the surface first and wait for it to dry. Take an appropriate amount of glycolic acid solution and apply it evenly to the surface with the pulp of your fingers to avoid the skin around the eyes, lips and mouth. For the first time, you can apply it every day to make the skin gradually comfortable. If the skin has strong tolerance, it can be increased to one use a day.

When using, pay attention to the feeling of the skin. If you feel too much tingling, wash off with water as soon as possible and suspend use. When the skin is calm, use it from a small amount or a few times. And after using glycolic acid, you must take care of the skin during the day, avoid direct sunlight, and use sunscreen products to avoid skin damage from ultraviolet rays.

When using glycolic acid, you should also pay attention to skin hydration. Because it can cause rapid renewal of the stratum corneum of the skin, or dry the skin. Therefore, after cleansing in the morning and evening, it is advisable to use a moisturizing water milk to maintain the hydrated state of the skin. In this way, the benefits of glycolic acid for skin maintenance can be obtained, and its harm can be avoided.
