  • Vc
    Vitamin C
    Strong · 13 studies

    Brightens dull skin and helps fade dark spots. Also defends against everyday UV and pollution damage when worn under sunscreen.

  • Re
    Retinol
    Strong · 12 studies

    Speeds up how fast your skin renews itself so old, dull cells shed faster and fresher skin shows through. Builds collagen over time, smoothing fine lines.

  • Ni
    Niacinamide
    Strong · 8 studies

    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.

  • Eg
    EGCG (Green Tea)
    Strong · 7 studies

    A polyphenol from green tea that calms UV-triggered redness and reinforces your sunscreen as a second line of antioxidant defense.

  • Ce
    Ceramides
    Strong · 6 studies

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

  • Pe
    Petrolatum
    Strong · 6 studies

    The gold-standard occlusive moisturiser. Locks water into damaged or compromised skin better than anything else, accelerates barrier repair, and (in newer research) actively boosts your skin's own antimicrobial defences. Cheap, non-allergenic, dermatologist-recommended for eczema, post-procedure care, and slugging.

  • Tr
    Tretinoin
    Strong · 5 studies

    The prescription-strength version of retinol. Same goals (smoother, more even skin), but works faster and is more irritating. Needs a doctor.

  • Om
    Colloidal Oatmeal
    Strong · 5 studies

    A pharmacy-grade skin protectant proven to calm itch, redness, and dryness in eczema and other irritated skin. FDA recognised it as a Category I skin protectant in 2003, and 1% creams beat vehicle in mild-to-moderate atopic dermatitis trials.

  • Dm
    Dimethicone
    Strong · 5 studies

    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.

  • Ch
    Cholesterol
    Strong · 5 studies

    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.

  • Ur
    Urea
    Strong · 4 studies

    A small molecule your skin already makes. Low concentrations deeply hydrate dry skin; higher concentrations soften thick, scaly patches. A workhorse for eczema and ichthyosis.

  • Gs
    Panax Ginseng
    Strong · 3 studies

    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.
