Hydrated magnesium silicate, commonly known as talc, is a naturally occurring mineral used in cosmetics and skincare as an absorbent, anti-caking, bulking, and texture-enhancing agent. It helps absorb moisture and oil, improves slip, and provides a smooth, mattifying feel in powders and creams.
| Reported effect | How often | Notes |
|---|---|---|
Skin dryness from oil absorption | Uncommon | May occur with frequent use on already dry skin due to its absorbent properties. |
Mild skin or eye irritation | Rare | Loose powder particles can cause transient irritation, particularly around the eyes. |
Respiratory irritation from inhalation of powder | Uncommon | Inhaling airborne particles during application of loose powders can irritate the respiratory tract. |
Contact dermatitis or allergic reaction | Very rare | Rarely reported; cosmetic-grade talc is generally well tolerated on intact skin. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
