Ice Pick Scars:
- Deep pits (usually less than 2mm across).

Mechanism of Action:
- Mechanically breaks down scar tissue.
- Activates cellular enzymes known as matrix metalloproteinases, or MMPs.
- Remodels scar tissue through the proper deposition of collagen and elastin.
- Addresses the red and purple discoloration associated with acne scars by increasing blood flow.
- Addresses the brown discolorations, or post inflammatory hyperpigmentation (PIH), associated with acne scars by stimulating the skin’s natural growth factors.
