What it's good for

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

  • PolydeoxyribonucleotideAnecdotal evidenceFull dossier ↗

    The "salmon DNA" trending in K-beauty and Korean clinics. Strong wound-healing pedigree translated into anti-aging. Speeds repair after lasers/microneedling, smooths fine lines, and brightens. Often layered with vitamin C and niacinamide. Worth knowing: salmon- or trout-derived PDRN has much stronger clinical evidence than plant ("phyto") PDRN, and the dose matters more than the marketing. Favor products that list a real PDRN concentration (roughly 1,000+ ppm) over big headline numbers on plant-derived versions.

    Good for: Barrier repair, Anti-aging

  • GlutathioneModerate evidenceFull dossier ↗

    A "master antioxidant" your body already makes. In skincare it gently lightens overall tone and helps fade pigmentation when used consistently over months.

    Good for: Brightening, Antioxidant

  • 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

  • AdenosineModerate evidenceFull dossier ↗

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

    Good for: Anti-aging

  • Hydrolyzed CollagenModerate evidenceFull dossier ↗

    The protein your skin loses with age, broken down small enough to absorb. Multiple meta-analyses of RCTs show measurable wins in wrinkles, elasticity, and hydration after ~12 weeks. Most evidence is oral, but topical helps surface hydration too.

    Good for: Anti-aging, 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
