Red pimple marks: Red pimple marks are usually post-acne light red spots, which are still scar tissue histologically. Medications such as retinoic acid cream can be used in moderation, which can promote collagen synthesis and improve skin texture and elasticity. Physical treatments such as intense pulsed light and non-ablative fractional laser can also be used to stimulate the rearrangement of scar tissue. 2.

Intense pulsed light can also gradually eliminate dark brown acne marks. 3. Scarring acne marks: Scarring acne marks are usually obvious scars left after acne. For this kind of scar, peeling fractional laser treatment is more effective, and it usually takes several treatments to achieve the ideal goal. For some larger depressed scars, you can choose hyaluronic acid filler or surgical excision, etc..
