Guidelines for using glycolic acid 7% toner
1. Preparations
Before using this product, you need to clean your face to ensure that your skin is clean and free of dirt. You can choose mild cleansing products, wash with warm water, gently wipe dry the facial moisture, and prepare for subsequent use of toner.

2. First trial
1. ** Local test **: When using glycolic acid 7% toner for the first time, you should try it on a small area of skin such as behind the ear or chin. Take an appropriate amount of toner on a cotton pad, gently wipe the selected area, and observe for 12-24 hours. If there is no discomfort such as redness, swelling, tingling, and itching, you can continue to use it.
2. ** Frequency of use **: In the early stage, it is recommended to use it every 2-3 days. After the skin gradually adapts, increase the frequency of use according to its own condition.

3. Normal use method
1. ** Dosage **: Take an appropriate amount of glycolic acid 7% toner on a cotton pad or palm. If using a cotton pad, soak the toner evenly on the cotton pad; if using the palm directly, pat the toner evenly on the face and neck. Be careful to avoid sensitive areas such as eye area and lips.
2. ** Wipe and pat **: When using a cotton pad, gently wipe from the center of the face outward. The action should be gentle to promote the absorption of the toner and achieve the secondary cleansing effect at the same time. When pat with the palm of your hand, gently press the toner on the skin to help it penetrate.
3. ** Follow-up skin care **: After the toner is fully absorbed, follow-up skin care steps, such as using serum, lotion or cream, etc., to lock in the skin moisture and nutrients.
