On the Usage of 70% Glycolic Acid
70% Fuglycolic Acid is strong and effective. It needs to be used cautiously in the way of skin recuperation.

At the beginning, when the skin tolerates it, take a little 70% glycolic acid solution, apply it to the skin in the wrist or behind the ear, and wait for a while. If the skin does not experience redness, swelling, itching, tingling and other discomfort, it can be used later.

When using it, it must be diluted. Because of its high concentration, apply it directly to the skin, and it may cause damage. Use distilled water or a suitable diluent, according to the appropriate ratio, slowly stir and smooth. It is safe to reduce the concentration of glycolic acid to a level acceptable to the skin.

When applying to the surface, first clean the surface and wipe it lightly with a dry towel. Then, use a cotton ball or a soft brush, dip it in the diluted glycolic acid solution, and gently apply to the surface. Avoid sensitive areas such as eyes, lips, and mouth. After applying, wait for a moment and watch the skin's reaction. If you feel too irritated, rinse with water as soon as possible.

And the frequency of use also needs to be controlled. For beginners, it is recommended to apply it every day. When the skin adapts, the frequency can be gradually increased. However, it should not be too frequent to prevent skin damage.

After using it, skin protection is especially important. Avoid direct sunlight and apply suitable sunscreen to prevent the skin from being irritated and photosensitized. In this way, only by using the method carefully can the 70% effect of glycolic acid nourish the beauty of the skin.
