What it's good for
Key actives from our research database. Click any to read the full evidence dossier.
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
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 modern broad-spectrum filter that covers both UVA and UVB and stays stable in sunlight. It is one reason many Korean and European sunscreens can combine high protection with a lighter feel.
Good for: Sun protection
A modern broad-spectrum filter known as Tinosorb M. It adds stable UVA and UVB coverage; because it is particulate, some formulas may show a slight cast depending on filter size and the rest of the base.
Good for: Sun protection
A polymeric UVB filter used to build lightweight, silky sunscreen textures. It supports SPF while its silicone backbone helps the formula spread into an even protective film.
Good for: Sun protection
A modern UVA filter common in Korean and European sunscreens. It fills the long-wave UVA gap that UVB-focused filters cannot cover and is valued for remaining stable during sun exposure.
Good for: Sun protection
A pure hydrator that holds water in your skin. Makes skin look plumper and smoother almost immediately.
Good for: Hydrating
Pro-vitamin B5. Deeply hydrates and helps repair the skin barrier, calming dry or compromised skin.
Good for: Hydrating, Barrier repair
A gentle smoother and skin-soother. Reduces flakiness and helps the surface look more even.
Good for: Anti-inflammatory, Hydrating
