The Anti-Aging Timeline

What to prioritize at each stage:

• Teens, twenties: daily sunscreen, gentle cleanser, simple moisturizer
• Late twenties, thirties: add a nightly retinoid and morning vitamin C
• Thirties, forties: stronger retinoid, peptides, maybe a professional peel
• Forties and beyond: keep the retinoid, richer moisturizer, consider prescription options

The core never changes: sunscreen, retinoid, hydration. The strength goes up with age; the foundation stays the same.
