Step-by-step instructions

1. Cleanse your face: Start with a clean and dry face. 
2. Apply the serum: Take a few drops of the serum onto your fingertips. Avoid the eye area. 
3. Dab and massage: Gently dab the serum onto your cheeks, forehead, chin, and neck. Then, use upward, circular motions to massage the serum into your skin until it is fully absorbed. 
4. Follow up: For morning use, follow with a sunscreen to protect your skin from sun damage. For both morning and evening, you can follow with your regular moisturizer. 
5. Frequency: Use the serum once or twice a day, as needed, to start. 

Important tips

• Patch test: Before using any new product, it is recommended to perform a patch test to check for any adverse reactions, especially since the serum contains glycolic acid. 
• Sun protection: Glycolic acid can make your skin more sensitive to the sun. It is crucial to use a sunscreen during the day to protect your skin.
