Acne scars treatments

Date: 10 Jan 2024

Treatment for depressed (sunk-in) acne scars: These scars may be treated with a procedure, acne scar surgery, or medication applied to the skin. Your dermatologist may use multiple treatments to give you the best results.

Treatment for depressed scars includes the following:  

  • Chemical peel: Applying a chemical peel to the skin helps the body produce more collagen and elastin. When the skin has more of both, depressed acne scars tend to be less noticeable.
  • Fillers: This treatment adds volume to depressed scars. Fillers can also help your body produce more collagen and elastin to fill in the scars. Dermatologists use different fillers, which last for varying amounts of time. Most fillers give temporary results, ranging from 3 months to 2 years.
  • Laser treatment: Dermatologists use lasers to resurface skin with acne scars. As your skin heals after laser resurfacing, it produces collagen and elastin, which can diminish the appearance of scars. Your dermatologist may also use a laser to contour skin around acne scars, which can diminish the appearance of scarring.
  • Microneedling: During this procedure, your dermatologist uses tiny needles to puncture the skin with acne scars. Puncturing the skin causes the body to produce new collagen and elastin. Also called “collagen induction therapy,” the new collagen helps diminish acne scars.
  • Platelet-rich plasma (PRP): Your dermatologist may use this treatment to enhance the results of another treatment like microneedling. PRP involves having a small amount of your blood drawn. This blood is placed into a machine that separates the blood so that your dermatologist can use your platelets.
  • Radiofrequency: This procedure uses radiofrequency waves to help your skin produce collagen and elastin. When your skin has more of these, acne scars are less noticeable.
  • Collagen stimulator: The new generation of acne scar treatments like PDLLA. The physician injects collagen stimulators into the scar to stimulate collagen and elastin production. Atrophic scars are less noticeable after one-time treatment.
