"Scars" are areas of fibrous tissue that form during wound healing and are not a skincare ingredient; they are a skin condition that various actives (e.g., silicone, retinoids, vitamin C, alpha hydroxy acids) may be used to treat or improve.
| Reported effect | How often | Notes |
|---|---|---|
| Not applicable — scars are a tissue/condition, not a topical agent | Very rare | No side-effect profile exists because this is not an applied substance; any adverse effects would relate to the treatments used on scars, not to scars themselves. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
