Is Aluminum Hydroxide a Good Ingredient?
Good: An inert, insoluble mineral that stabilizes and coats pigments, improving texture with low likelihood of irritation. Benefits are consistent across many formats, though it is not an active skin treatment.
What it does
Skin Benefits
Creates a smoother look by diffusing light and helping pigments apply more evenly. Helps shield sensitive ingredients so shades remain stable during wear.
Where you'll find it
Uses in Skincare & Cosmetics
Used in sunscreens to treat mineral filters, and in foundations, BB creams, and lipsticks to improve texture and color uniformity.
Before you use it
Safety
Low irritation potential and minimal skin penetration due to its insolubility. Rare sensitization can occur; avoid inhaling loose powders and keep away from broken skin.
