Tretinoin
Tretinoin (Retin-A) is a prescription-strength retinoid that's more potent than over-the-counter retinol. It's the most studied anti-aging ingredient with decades of research backing its effectiveness.

How It Works
Unlike retinol, tretinoin doesn't need to convert—it's already in the active retinoic acid form. This makes it more potent and effective, but also more likely to cause irritation initially.
