Precautions:
1. During the treatment, do not use hot water for rinsing within the last week, and do not apply any medication or ointment by yourself.
2. After the surgery, direct sunlight exposure is strictly prohibited. Pay attention to hydration and repair.
3. During the treatment, avoid infrared therapy and saunas.
4. During the treatment, refrain from eating spicy, stimulating foods, and allergenic foods (beef, lamb, seafood, peppers).
5. After the treatment, facial spots may temporarily darken and form a crust. Note: Do not manually peel off the pigment crust; let it fall off naturally. It will typically fall off on its own in about 7-10 days.
