Tretinoin Guide: Start, Purge, and Thrive
Tretinoin is the gold standard for anti-aging and acne. This comprehensive guide covers how to start, survive the purge, and get the best results from prescription retinoids.
What is Tretinoin?
Tretinoin (Retin-A) is a prescription retinoid—the most studied and effective topical anti-aging ingredient. It increases cell turnover, boosts collagen, and treats acne at the source.
How to Start Tretinoin
Start with the lowest strength (0.025%) 2-3 times per week. Apply a pea-sized amount to dry skin. Use the 'sandwich' or 'buffer' method if irritated: moisturizer, tretinoin, moisturizer.
Surviving the Purge
The purge is a temporary increase in breakouts as tretinoin accelerates cell turnover. It typically lasts 4-8 weeks. Push through—it's a sign the product is working.
Long-Term Use and Results
Real results take 3-6 months. After a year, you'll see significant improvements in fine lines, texture, and tone. Tretinoin is a long-term commitment, not a quick fix.
