TIPS: Before or during the application of the face patch, use the small strip to test the sensitivity of the skin in the inconspicuous area according to the instructions. For dry or sensitive skin, apply moisturizer for 30 minutes before using the anti-wrinkle patch and let it absorb before using it. Precautions: All first-time users: Test allergy by sticking a small strip on the back of the hand to reduce adhesion. And wear it for 20 minutes. If there is no redness, you can start using the face sticker, which can be removed after two hours of wearing it. It needs to be unlocked slowly when taking it off. Everyone's skin is different. It is normal if the redness disappears after 2 minutes.
