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
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
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
A polyphenol from green tea that calms UV-triggered redness and reinforces your sunscreen as a second line of antioxidant defense.
Good for: Antioxidant, Anti-inflammatory, Sun protection
A workhorse hydrator that pulls water into your skin. In nearly every good moisturizer for a reason.
Good for: Hydrating
A pure hydrator that holds water in your skin. Makes skin look plumper and smoother almost immediately.
Good for: Hydrating
Pro-vitamin B5. Deeply hydrates and helps repair the skin barrier, calming dry or compromised skin.
Good for: Hydrating, Barrier repair
The mildest exfoliating acid. Refines texture and hydrates at the same time, and it's sensitive-skin friendly.
Good for: Exfoliating, Hydrating
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
