What it's good for

Key actives from our research database. Click any to read the full evidence dossier.

  • DHHBModerate evidenceFull dossier ↗

    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

  • Ethylhexyl TriazoneModerate evidenceFull dossier ↗

    A high-efficiency UVB filter behind many elegant high-SPF Korean and European formulas. It contributes strong burn protection without requiring the heavier filter load of less efficient UVB absorbers.

    Good for: Sun protection

  • NiacinamideStrong evidenceFull dossier ↗

    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

  • Beta-GlucanModerate evidenceFull dossier ↗

    A heavy-duty hydrator that also reduces irritation. Often called "better than hyaluronic acid" for sensitive skin.
