What it's good for
Key actives from our research database. Click any to read the full evidence dossier.
Calms irritation and adds light hydration. The classic for sunburned or reactive skin.
Good for: Anti-inflammatory, Hydrating
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 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.
Good for: Barrier repair, Hydrating
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
Exfoliates the surface of your skin to smooth rough texture and fade dullness. The strongest of the AHAs, so start slow.
Good for: Exfoliating
The mildest exfoliating acid. Refines texture and hydrates at the same time, and it's sensitive-skin friendly.
Good for: Exfoliating, Hydrating
A lightweight oil that mimics what your skin already makes. Softens and seals in hydration without feeling greasy.
Good for: Barrier repair, Hydrating
A workhorse antioxidant that defends your skin from daily oxidative damage. Pairs especially well with vitamin C, and it's in nearly every good moisturizer for a reason.
Good for: Antioxidant
