Scar is an imported silicone produced in the United States. It is mainly used to treat and prevent scars, burns or acne left after surgery. The application method is 1 time in the morning and evening, and it is applied locally to the affected area when getting up in the morning and before going to bed at night. If there is cleaning, washing your face or sweating a lot in the middle, you can touch it up. Generally speaking, it is best to use it 3 days after suture removal after operation. The sooner the better, the principle is to avoid direct application of wounds and pinholes. It should be used continuously for at least 3 months or even longer.
