What it's good for

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

  • AdenosineModerate evidenceFull dossier ↗

    A Korean-approved anti-wrinkle ingredient that encourages collagen production for a smoother, firmer look.

    Good for: Anti-aging

  • Bifida Ferment LysateModerate evidenceFull dossier ↗

    A probiotic-based ingredient that strengthens your skin's defenses against irritation and environmental stress.

    Good for: Barrier repair, Anti-inflammatory

  • Centella AsiaticaModerate evidenceFull dossier ↗

    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

  • CeramidesStrong evidenceFull dossier ↗

    Refills the natural barrier between your skin cells. Locks moisture in, keeps irritants out, calms dry or damaged skin.

    Good for: Barrier repair

  • CholesterolStrong evidenceFull dossier ↗

    The third (and most often missing) lipid in the skin barrier triumvirate. Without it, even ceramide-heavy creams underperform. Topping it up is what lets compromised, aged, or eczema-prone skin actually rebuild its waterproof layer.

    Good for: Barrier repair

  • Coenzyme Q10Moderate evidenceFull dossier ↗

    A naturally-occurring antioxidant your skin loses as you age. Topical CoQ10 restores some of what time depletes, supporting energy production in skin cells and softening wrinkle depth.

    Good for: Antioxidant, Anti-aging

  • 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

  • Hyaluronic AcidStrong evidenceFull dossier ↗

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

    Good for: Hydrating

  • IdebenoneAnecdotal evidenceFull dossier ↗

    A lab-engineered version of CoQ10 that gets deeper into skin cells. Modest visible improvements over months. Comparison studies place it below vitamin-C-plus-ferulic combos, but it's useful when C is poorly tolerated.

    Good for: Antioxidant, Anti-aging

  • Jojoba OilModerate evidenceFull dossier ↗

    Technically a wax that masquerades as oil, molecularly closer to your own sebum than any other plant oil. Hydrates without clogging pores, calms inflammation, and plays well in acne-prone and sensitive routines.

    Good for: Hydrating, Barrier repair, Anti-inflammatory

  • Matrixyl PeptidesModerate evidenceFull dossier ↗

    Signals your skin to make more collagen. Quiet but real support for firmness and fine lines with consistent daily use.

    Good for: Brightening, Barrier repair, Anti-inflammatory

  • PanthenolModerate evidenceFull dossier ↗

    Pro-vitamin B5. Deeply hydrates and helps repair the skin barrier, calming dry or compromised skin.

    Good for: Hydrating, Barrier repair

  • Shea ButterModerate evidenceFull dossier ↗

    A rich, naturally occlusive plant butter from the African karite tree. Soothes dry, irritation-prone skin, refills the lipid barrier, and was well tolerated enough in randomized trials that most participants used it comfortably as a daily emollient.

    Good for: Barrier repair, Hydrating, Anti-inflammatory

  • 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.
