Dark marks: most should be gone
Deeper color can take longer. Ask a dermatologist about treatment if marks persist.
General timelines, not medical advice. Stop and get advice if you have burning, swelling, or a rash.
How this tool works
- Timelines come from the American Academy of Dermatology and, for adapalene, its prescribing information.
- The "judge it" date is when you should compare progress photos and decide whether to keep going, not when acne should be gone.
- Dark marks run on a separate, longer clock: a few shades darker than your skin usually fades within 6 to 12 months.
- Dates stay in your browser. The calendar file is created on your device.
