What it's good for

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

  • BisabololModerate evidenceFull dossier ↗

    The "calm-down" molecule in many sensitive-skin formulas. Reduces redness and stinging without bleaching your barrier, and plays nicely on top of retinoids or exfoliating acids.

    Good for: Anti-inflammatory

  • DimethiconeStrong evidenceFull dossier ↗

    A silicone that sits on your skin as an invisible, non-greasy shield. Reduces water loss, protects against irritants (think soap, friction, incontinence), and is FDA-recognised as a skin protectant from 1-30%. The reason your favourite primer feels silky and your barrier cream actually works under makeup.

    Good for: Barrier repair, Hydrating

  • GlycerinModerate evidenceFull dossier ↗

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

    Good for: Hydrating

  • Linoleic AcidModerate evidenceFull dossier ↗

    An essential fatty acid your sebum runs short on if you're acne-prone, and topping it up topically literally shrinks clogged pores. Also rebuilds the lipid mortar between skin cells. Found concentrated in safflower, hemp, and rosehip oils.

    Good for: Barrier repair, Anti-acne

  • Snow MushroomAnecdotal evidenceFull dossier ↗

    Often pitched as the gentler cousin of hyaluronic acid. It holds water in the skin, fades less quickly in dry air, and quietly buffers against UV oxidative stress.

    Good for: Hydrating, Antioxidant, Barrier repair

  • Vitamin EModerate evidenceFull dossier ↗

    A workhorse antioxidant that defends your skin from daily oxidative damage. Pairs especially well with vitamin C, and it's in nearly every good moisturizer for a reason.

    Good for: Antioxidant
