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.

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.

Uses in Skincare & Cosmetics

Used in sunscreens to treat mineral filters, and in foundations, BB creams, and lipsticks to improve texture and color uniformity.

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.
