Accutane for Acne Scars: Effective Only for Acne Vulgaris Scarring, Not Other Types

Isotretinoin (Accutane) is a potent retinoid for severe nodulocystic acne. Its effect on scars is often misunderstood.

What It Treats

• Active acne vulgaris: Reduces sebum, normalizes keratinization, shrinks sebaceous glands, anti-inflammatory.
• Post-inflammatory erythema (PIE) & hyperpigmentation (PIH): Indirectly, by preventing new lesions and reducing inflammation.
• Shallow atrophic scars: Mild improvement via collagen remodeling during treatment.

What It Does NOT Improve

• Deep atrophic scars (icepick, boxcar, rolling).
• Surgical scars, trauma scars, burn scars.
• Keloid/hypertrophic scars.
• Stretch marks (striae).

Effective Scar Treatments

• Microneedling, fractional laser (CO₂, erbium), subcision, TCA CROSS, fillers, PRP.
• Surgical excision for isolated deep scars.
• Silicone gel/sheets for hypertrophic/keloid scars.

Isotretinoin must be completed before ablative procedures (wait 6–12 months post-course) due to impaired wound healing risk.
