No fungal-acne, pore-clogging, fragrance or drying-alcohol flags for Titanium Dioxide in our reference data.
Titanium dioxide is an inorganic mineral compound used primarily as a physical (mineral) sunscreen agent that reflects and scatters UV radiation, and also serves as a white pigment and opacifier in cosmetic formulations. It is broadly photostable and considered gentle, making it common in products for sensitive and pediatric skin.
| Reported effect | How often | Notes |
|---|---|---|
White cast on skin | Common | Cosmetic effect, more pronounced on deeper skin tones and with non-micronized grades. |
Skin dryness or mild irritation | Uncommon | Usually related to the overall formulation rather than the ingredient itself. |
Contact dermatitis or allergic reaction | Rare | Titanium dioxide is a recognized low-sensitizing ingredient; reactions are infrequent. |
Comedogenicity / clogged pores | Rare | Can occur in some individuals depending on coating and formulation base. |
Inhalation-related respiratory concern | Very rare | Relevant only to loose powder/spray forms via inhalation, not topical leave-on use. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
