In skincare, 'minerals' refers to inorganic compounds such as zinc oxide, titanium dioxide, iron oxides, and mica used for sun protection, pigmentation, and oil absorption. They are generally well tolerated and considered relatively inert on the skin.
| Reported effect | How often | Notes |
|---|---|---|
White cast or visible residue on skin | Common | Particularly with non-nano zinc oxide and titanium dioxide in sunscreens. |
Skin dryness or tightness | Uncommon | Absorbent minerals can reduce surface oils, occasionally causing dryness. |
Mild irritation or clogged pores | Uncommon | More likely with heavy mineral makeup or occlusive formulations. |
Contact allergy or sensitivity reaction | Rare | Mineral filters are among the least sensitizing; reactions are uncommon and often tied to other formulation components. |
Concern over inhalation of loose mineral powders | Rare | Relevant mainly to aerosolized or loose-powder products, not topical application. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
