What it's good for
Key actives from our research database. Click any to read the full evidence dossier.
A gentle smoother and skin-soother. Reduces flakiness and helps the surface look more even.
Good for: Anti-inflammatory, Hydrating
Refills the natural barrier between your skin cells. Locks moisture in, keeps irritants out, calms dry or damaged skin.
Good for: Barrier repair
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
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
An FDA-recognised skin protectant that helps soothe the feeling of itch, redness, and dryness on irritated skin. FDA recognised it as a Category I skin protectant in 2003, and 1% creams showed improvement over their base formula for dry, irritation-prone skin in controlled trials.
Good for: Barrier repair, Anti-inflammatory, Hydrating
A workhorse hydrator that pulls water into your skin. In nearly every good moisturizer for a reason.
Good for: Hydrating
Exfoliates the surface of your skin to smooth rough texture and fade dullness. The strongest of the AHAs, so start slow.
Good for: Exfoliating
A pure hydrator that holds water in your skin. Makes skin look plumper and smoother almost immediately.
Good for: Hydrating
A "next-gen AHA" that exfoliates and hydrates at the same time, with much less stinging than glycolic. Sensitive-skin or rosacea-prone users tolerate it where stronger acids fail.
Good for: Exfoliating, Hydrating, Antioxidant
Goes into your pores and dissolves the oil and dead skin clogging them. Best for blackheads, whiteheads, and oily, acne-prone skin.
Good for: Anti-acne, Exfoliating
A gentler grape-derived AHA that exfoliates and helps multi-acid formulas stay at the right pH to work. Less studied than glycolic or lactic acid as a standalone, but well-tolerated in combination peels, and the antioxidant side effect is a genuine bonus.
Good for: Exfoliating, Antioxidant
A botanical astringent backed by real anti-inflammatory evidence. Extracts genuinely calm acne-related inflammation by blocking the same NF-κB pathway that redness-causing cytokines depend on. Honest caveat: most shelf-ready witch hazel toners are distilled water with trace tannin; look for "Hamamelis virginiana extract" rather than "hamamelis water" on the label if you want the active fraction.
Good for: Anti-inflammatory, Anti-acne
