What it's good for
Key actives from our research database. Click any to read the full evidence dossier.
The protein your skin loses with age, broken down small enough to absorb. Multiple meta-analyses of RCTs show measurable wins in wrinkles, elasticity, and hydration after ~12 weeks. Most evidence is oral, but topical helps surface hydration too.
Good for: Anti-aging, Hydrating
Also called "cica," it calms redness, repairs the skin barrier, and speeds up recovery. The go-to for irritated or reactive skin.
Good for: Anti-inflammatory, Barrier repair
A multitasker that calms redness, evens out skin tone, and helps oily skin balance out. One of the safest do-a-little-of-everything ingredients.
Good for: Brightening, Barrier repair, Anti-inflammatory
Refills the natural barrier between your skin cells. Locks moisture in, keeps irritants out, calms dry or damaged skin.
Good for: Barrier repair
A supporting UVB filter in many lightweight chemical sunscreens. It helps a formula reach its labeled SPF, but it needs UVA partners such as avobenzone for broad-spectrum coverage.
Good for: Sun protection
A UVB filter and formula stabilizer commonly paired with avobenzone. It helps broad-spectrum sunscreen keep working in sunlight, though people with a history of sunscreen photoallergy may prefer an alternative filter system.
Good for: Sun protection
A supporting UVB filter that improves both protection and formula feel. It is rarely the star of a sunscreen, but it helps the complete filter blend deliver the SPF printed on the bottle.
Good for: Sun protection
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.
Good for: Sun protection
