1. Scar patches should be used at least 12 hours a day, preferably 24 hours a day, and continuously for 2-4 months
2. To avoid skin allergies, a gradual application method can be used to gradually adapt the skin
3. Each scar patch can be reused for 14-28 days. When the scar patch becomes difficult to clean or stick, another new scar patch needs to be replaced
Tip: Apply for 4 hours a day for the first two days, then 8 hours a day for the next two days, and increase by 2 hours a day until it can be applied 24 hours a day
