What it's good for

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

  • Hyaluronic AcidStrong evidenceFull dossier ↗

    A pure hydrator that holds water in your skin. Makes skin look plumper and smoother almost immediately.

    Good for: Hydrating

  • 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

  • GlycerinModerate evidenceFull dossier ↗

    A workhorse hydrator that pulls water into your skin. In nearly every good moisturizer for a reason.

    Good for: Hydrating

  • AvobenzoneModerate evidenceFull dossier ↗

    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

  • HomosalateModerate evidenceFull dossier ↗

    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

  • OctisalateModerate evidenceFull 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

  • OctocryleneModerate evidenceFull dossier ↗

    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
