Sun protection.
Mineral and chemical UV filters that block or absorb radiation before it reaches the cell. The single highest-impact category for preventing photoaging and pigmentation, and the only one regulated as a 'drug active' in most countries.

- EGCG (Green Tea)Strong evidence
A polyphenol from green tea that calms UV-triggered redness and reinforces your sunscreen as a second line of antioxidant defense.
- Titanium DioxideStrong evidence
Another physical sunscreen that blocks UV. Often paired with zinc oxide for full sun protection.
- AvobenzoneModerate evidence
The most widely used chemical UVA filter in Western sunscreens, critical for blocking the longer wavelengths that drive photoaging, pigmentation, and deeper DNA damage. Always look for it paired with a photostabiliser such as octocrylene so it doesn't degrade and leave you unprotected mid-day.
- OctinoxateModerate evidence
The UVB workhorse behind most chemical sunscreens: effective, well-tolerated, and found in over 90% of chemical-filter formulas in the US. Important caveat: it covers UVB only, so it always needs a UVA partner (typically avobenzone). Also banned in Hawaii and reef-sensitive areas due to coral toxicity, so check the label if environmental impact matters to you.
- Polypodium LeucotomosModerate evidence
A supplement (and topical) that adds an internal layer of sun protection on top of your sunscreen, popular for melasma and easily-burned skin. Not a sunscreen replacement, but a real adjunct.
- TocotrienolModerate evidence
Vitamin E's more potent cousin, better at chasing down free radicals and shielding skin from UV-driven aging. A systematic review concluded it protects against inflammation, UV damage, and pigmentation; pairs naturally with vitamin C.
- Zinc OxideModerate evidence
A physical sunscreen that sits on top of your skin and blocks UV. Broad-spectrum and gentle enough for sensitive or rosacea-prone skin.
