Our take
Is Selenium a Good Ingredient?
Fair, because the antioxidant potential is plausible, but human data for topical skincare are limited, so results may be modest. Certain forms can also irritate or be unsuitable at higher levels, so the benefit depends heavily on form and concentration.
What it does
Skin Benefits
May aid in neutralizing free radicals and supporting a product's antioxidant system, though evidence for visible skin changes from topical use is limited.
Where you'll find it
Uses in Skincare & Cosmetics
Found in antioxidant-focused serums and moisturizers, often paired with vitamins C or E.
Before you use it
Safety
Generally used at low levels but may cause irritation in some users. Some selenium compounds, such as selenium sulfide, are restricted to specific uses and concentrations, mainly in rinse-off anti-dandruff products. Discontinue if irritation occurs.
