It appears in sunscreens, primers, and light textures. Pregnancy safety. It evaporates quickly after application, systemic absorption is low, and there is no evidence of harm. It can be used during pregnancy and lactation. Tolerance. Irritation and allergen potential are low, and it is non-comedogenic.
