What it's good for
Key actives from our research database. Click any to read the full evidence 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
A traditional Japanese brightener with built-in antioxidants. Softens, hydrates, and adds glow.
Good for: Brightening, Antioxidant
A natural acne spot-treatment that kills the bacteria behind red, painful pimples. Slower than benzoyl peroxide but with fewer side effects when used at 5%.
Good for: Anti-acne, Anti-inflammatory
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
A heavy-duty hydrator that also reduces irritation. Often called "better than hyaluronic acid" for sensitive skin.
Good for: Hydrating, Anti-inflammatory
Another cica (centella) compound. This one specifically pushes collagen production, so the benefit is more about firmness than calming.
Good for: Anti-aging, Anti-inflammatory
