Tretinoin is widely considered the gold standard of anti-aging and acne treatments. However, its potency means that improper use can lead to irritation and the dreaded “tretinoin purge.”
The Tretinoin Purge Timeline
- Weeks 1-2: Initial dryness and possible irritation. Start slow (2-3 nights per week).
- Weeks 3-6: Peak purging (new breakouts as skin turnover increases).
- Weeks 8-12: Improvement in texture and reduction in new acne.
The “Sandwich Method” for Irritation
If you have sensitive skin, try applying moisturizer before AND after tretinoin:
- Wash face with a gentle cleanser.
- Apply a thin layer of moisturizer.
- Wait 15 minutes.
- Apply a pea-sized amount of tretinoin.
- Apply another layer of moisturizer.
