Fine lines & wrinkles
Fine lines and wrinkles form as skin loses collagen over time, mostly from sun exposure. Retinoids have the strongest evidence, and a dermatologist can discuss prescription tretinoin or in-office options.
Actives that work
Retinol / retinoids
strong evidence Typical: 0.25-1% retinol
Retinoids bind skin receptors that boost collagen and speed cell turnover. Trials show visible fine-wrinkle improvement, with prescription tretinoin strongest and over-the-counter retinol milder.
Bakuchiol
emerging evidence Typical: 0.5-1%
A plant-derived retinol alternative that acts on some of the same skin pathways with less irritation. One small head-to-head trial found it comparable to retinol, so the evidence is early.
Vitamin C (L-ascorbic acid)
moderate evidence Typical: 10-20%
An antioxidant that supports collagen production and helps neutralize UV-generated free radicals. Small trials show improved photoaging scores, and it works best at low pH.
Niacinamide
moderate evidence Typical: 2-5%
Supports the skin barrier and affects pigment and surface texture. A 12-week split-face trial showed fewer wrinkles and spots.

Paula's Choice / 1 oz / $43.87
A 1% retinol with peptides and antioxidants for people who have tolerated lower strengths. Trial data on 0.4-0.5% retinol suggests higher isn't required, so ramp up slowly.

Medik8 / 1 oz / ~$55
Retinaldehyde converts to retinoic acid in one step, so it is a gentler step toward prescription-style effects. Direct trial evidence for this product is limited; the class evidence is strong.
