In London, Ontario, effective acne scar treatments include: microneedling (often with PRP) to stimulate collagen; fractional and ablative lasers (CO₂, erbium) for deeper scars; chemical peels like TCA and PRX‑T33 to resurface skin; subcision and dermal fillers for depressed (atrophic) scars; and consistent medical‑grade skincare. https://penzu.com/public/da272fe34a3373dc
