WHAT I'D BUY

What I'd recommend and why.

Most clinical trials test ingredients, not brands. I use that evidence to decide which formulations are worth recommending — then I tell you why this one and not that one.

When I recommend a product, I'm making two judgment calls: does the ingredient have strong comparative evidence, and is this a sensible formulation that delivers it at the right concentration?

These recommendations are educational, not medical advice. Some links are affiliate links — marked clearly. I recommend these whether or not there's a link.

SkinCeuticals C E Ferulic

15% L-ascorbic acid + 1% tocopherol + 0.5% ferulic acid

Why this one: 15% L-ascorbic acid is the most-tested concentration for photoaging, and this formulation matches what the strongest trials actually used. It's expensive — but the specific combination of vitamin C, vitamin E, and ferulic acid has more direct evidence behind it than cheaper alternatives I've seen.

La Roche-Posay Retinol B3

Retinol 0.3% + niacinamide 2%

Why this one: 0.3% retinol is a reasonable starting point — strong enough to show results in trials but gentle enough to not wreck your barrier. The niacinamide at 2% may help with tolerability. If you're new to retinol, this is where I'd start.

EltaMD UV Clear SPF 46

Zinc oxide 9% + niacinamide 2%

Why this one: zinc oxide is the best-studied mineral UV filter. This formulation adds niacinamide at 2% — within the range the research supports for oil control. Cosmetically elegant for a mineral sunscreen, which matters because the best sunscreen is the one you'll actually wear.

Evidence first. Then recommendations.

I rank ingredients by comparative evidence before I recommend any product. If I can't find a formulation worth recommending, I don't list anything — an empty shelf is more honest than a padded one.
