Retinaldehyde for post-acne marks — what it is, how it works and how to add it to your routine without irritation.
Retinaldehyde is increasingly recommended for exactly this — and for good reason.
Retinaldehyde (retinal) acts faster than retinol but is gentler than prescription retinoic acid.
Post-acne refers to lingering marks and unevenness left after breakouts. This is exactly where Retinaldehyde shines: retinaldehyde (retinal) acts faster than retinol but is gentler than prescription retinoic acid. As a result, used consistently, it gently improves the skin for post-acne marks.
A good compromise between potency and tolerance for experienced users. Don't pick at breakouts — that's the main cause of marks and scars.
First changes are usually visible after 4–8 weeks of consistent use; lasting results take 2–3 months.
Start 2–3 times a week and build up based on how your skin responds. Don't pick at breakouts — that's the main cause of marks and scars.
A good compromise between potency and tolerance for experienced users. If in doubt, consult a cosmetologist or dermatologist.
