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

  • ArgirelineModerate evidenceFull dossier ↗

    Sometimes called "topical Botox," it's a peptide that subtly reduces the depth of expression lines around the eyes and forehead when used daily over months. Mild effect, but real.

    Good for: Anti-aging

  • BeeswaxModerate evidenceFull dossier ↗

    A wax film former that quietly does what petrolatum does (slows water loss and shields chapped skin) without feeling slick. Most evidence comes from honey/beeswax/olive-oil cerates that have shown improvement in dry, irritation-prone skin in controlled trials. CIR-affirmed safe.

    Good for: Barrier repair, Hydrating

  • 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

  • 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

  • MugwortAnecdotal evidenceFull dossier ↗

    A Korean botanical that calms angry, reactive skin. Especially soothing during flare-ups.

    Good for: Anti-inflammatory

  • 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

  • Panax GinsengStrong evidenceFull dossier ↗

    A staple in Hanbang (traditional Korean medicine) skincare. It's packed with antioxidants and ginsenosides that help firm the skin, boost circulation, and defend against environmental aging.

    Good for: Anti-aging, Antioxidant, Barrier repair

  • Reishi MushroomAnecdotal evidenceFull dossier ↗

    An "adaptogen" mushroom that helps skin cells handle stress at the gene level. Early-stage evidence but mechanistically interesting for anti-aging routines layered with vitamin C or peptides.

    Good for: Antioxidant, Anti-aging

  • 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
