Guidelines for using glycolic acid 7% toner
Preparations
If you want to use glycolic acid 7% toner, you must first cleanse your skin, cleanse your face with water or a mild cleanser, and wipe dry. Make sure your skin is dry and free of dirt and oil before applying this toner, which can help it penetrate better and play an effective role.

Frequency of use
For beginners, it is appropriate to use it every two days. When the skin adapts, it can be gradually increased to once a day. Do not rush for success and use it frequently. If the skin is sensitive, it should be more cautious. You can try it before a small piece of skin, observe its reaction, and then determine the frequency of use.

Specific Usage
Take an appropriate amount of toner on a cotton pad or palm. After dipping the cotton pad in moisture, gently wipe it from the center of the face outward and from bottom to top. The action should be slow, and pay attention to avoid the delicate skin around the eyes and lips. If applying in the palm of your hand, pat it on the face and neck until fully absorbed.

Follow-up care
With a toner, you should apply a moisturizing lotion or cream in a timely manner to lock in the skin's moisture and strengthen the skin's barrier. After daytime use, be sure to apply sunscreen. Because glycolic acid can make the skin more sensitive to ultraviolet rays, sun protection is indispensable to protect the skin from damage.

Precautions
If the skin has tingling, redness, swelling, itching and other discomfort during use, it should be stopped immediately and washed off with water. If the symptoms do not slow down or worsen, seek medical attention immediately. And this toner is for external use only, do not enter the mouth or eyes. If you do not enter it carefully, rinse with plenty of water immediately. When storing, place it in a cool and dry place away from direct sunlight and high temperature to ensure its quality and efficacy.
