What it's good for

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

  • 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

  • Citric AcidModerate evidenceFull dossier ↗

    A fruit-derived AHA that exfoliates and antioxidizes. It shares the same basic mechanism as glycolic and lactic acid but is weaker gram-for-gram; in practice you'll see it doing dual duty (a little exfoliation plus pH stabilisation) in multi-acid toners and serums. When it appears low on an ingredient list, it's adjusting pH; higher up, it's contributing real exfoliation.

    Good for: Exfoliating, Antioxidant

  • 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

  • Lactobacillus FermentAnecdotal evidenceFull dossier ↗

    A "postbiotic" (dead probiotic bits) that talks to your skin microbiome without adding live bugs. Patches up a leaky barrier and is friendly even on very reactive skin.

    Good for: Barrier repair, Hydrating

  • MugwortAnecdotal evidenceFull dossier ↗

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

    Good for: Anti-inflammatory

New to this? Patch test on your inner arm for 24 to 48 hours before applying to your face. If you have sensitive skin or rosacea, start 2 to 3 times per week and build up slowly.
