Initial Glycolic Acid Use Guide
Glycolic acid has unique ability in the way of skin care, but those who are new to it should use it wisely and carefully.

1. Initial Glycolic Acid
Glycolic acid is a kind of fruit acid, with small molecules and strong power to penetrate the skin. It can loosen the connection between keratinocytes, allowing old waste keratin to fall, making the skin surface smooth and delicate, and rejuvenating the clear appearance. And it can promote collagen production, reduce fine lines, and restore the skin to a firming state.

2. Prepare before use
For those with sensitive skin, be sure to apply a small amount of glycolic acid-containing products to the local skin, such as behind the ear or inside the forearm, before use, and wait for 24 hours. If there are no abnormalities, such as redness, itching, tingling, etc., it can be used on the face. At the same time, prepare a gentle cleansing product, moisturizing lotion and sunscreen to protect the skin.

3. How to use
When using for the first time, the frequency should be slow, preferably once to twice a week. After cleansing, wait for the face to be slightly dry, take an appropriate amount of glycolic acid-containing products, and apply gently to the face to avoid the delicate parts of the hairline, eye area and lips. After applying, you can wait for a few minutes, wait for it to dry slightly, and then apply a moisturizing lotion to lock in the water. As the skin adapts, the frequency of use can be gradually increased, but it should not exceed four times a week.

4. Precautions
After using glycolic acid during the day, be sure to strictly protect against the sun. Because it makes the skin more sensitive to ultraviolet rays, if there is no protection, it is easy to cause sunburn, tanning, and even accelerate skin aging. Furthermore, during use, do not use with other irritating products, such as high-concentration salicylic acid, retinoic acid, etc., to prevent skin intolerance and discomfort. If the skin feels uncomfortable during use, stop immediately, rinse with water, and seek medical treatment if necessary.

The initial use of glycolic acid, following this, can avoid the risk of skin damage, enjoy the benefits of its maintenance, and make the skin gradually better.
