Fractional laser** acne scars and acne pits are an effective method. Fractional lasers, especially CO2 fractional lasers, can precisely target acne pits and acne scars, stimulate collagen regeneration within the acne scars, thereby improving the appearance of acne scars.
*The exact number of times varies depending on the individual** condition and the severity of the acne scars, but generally requires 3 to 5 times**, with an interval of about 3 months** between each time. This is because it takes a certain amount of time for collagen regeneration within the body, about 3 to 6 months. For non-ablative fractional lasers, the interval may be shorter, but this needs to be determined based on your doctor's recommendations.
The cost of fractional laser is generally calculated according to the specific operating area (square centimeters), and the cost of a single laser is 1000 yuan to 8000 yuan. The cost will also be affected by the region, the hospital, and the type of instrument used (e.g., domestic, imported, peeling, non-peeling, etc.).
Overall, fractional laser acne scar pits are a safe and effective method, but the exact number of times and cost need to be determined on an individual basis. In order to achieve better results, it is recommended to seek help from a professional doctor in a regular hospital.
