Wrinkles & aging
The best-proven category in skincare — but also the most oversold. A few ingredients genuinely remodel skin; most 'anti-aging' claims ride on them.
What has evidence, ranked
Real trial support — almost all of it industry-funded
19 trials/reviews indexed · one or two solid randomized trials

11 trials/reviews indexed · one or two solid randomized trials
Consistent small trials show smoother, firmer skin
26 trials/reviews indexed · one or two solid randomized trials
A classic double-blind trial showed clear improvement at 8%

Small but measurable fine-line improvement at 5%
10 trials/reviews indexed · one or two solid randomized trials
12% improved firmness and fine wrinkling in controlled testing
27 trials/reviews indexed · one or two solid randomized trials
Several controlled trials show small but real wrinkle improvement
2 trials/reviews indexed · one or two solid randomized trials
Matched retinol in one 44-person trial — promising, unreplicated
4 trials/reviews indexed · a small trial, or mostly lab data so far
Softens the look of lines by hydration, not structure
64 trials/reviews indexed · a small trial, or mostly lab data so far
Industry-funded trials show small improvements; independent data scarce
An antioxidant bodyguard — the trial wins belong to C+E together
4 trials/reviews indexed · a small trial, or mostly lab data so far
Retinoid logic, minimal direct trial proof

Honest note: the best anti-ager is boring
Daily sunscreen has the single strongest evidence for preventing visible aging (randomized-trial proof). Collagen in a cream can't reach where collagen matters — the molecule is too large; it's a moisturizer with good marketing. Peptides remain 'promising, unproven'.
