For these of us who get hyperpigmentation like melasma or darkish spots from scars and pimples, daylight is the enemy. It could possibly make the discoloration deeper and tougher to do away with. Whereas utilizing SPF, usually, is crucial for managing hyperpigmentation, Elizabeth Kream, MD, a dermatologist based mostly in Chicago, says it is particularly helpful to search for mineral sunscreens that embrace iron oxide.
“In case you are susceptible to hyperpigmentation, and particularly for these with pores and skin of shade, please use a bodily sunscreen, notably one with iron oxide,” says Dr. Kream, who’s at the moment in her third yr of residency on the College of Illinois at Chicago. “Go for a bodily sunscreen with a tint. The tint sometimes implies that the energetic ingredient iron oxide can be on board, and this ingredient additionally supplies seen mild safety along with UV safety. Seen mild is what we see—it is what goes by home windows and is a identified exacerbator of melasma and photo-aging.”
A 2020 research, which examined the efficacy of sunscreens with iron oxide on pores and skin of shade, confirms that these formulation must be the highest decide for anybody coping with hyperpigmentation. It discovered that iron-oxide-containing formulations “considerably protected in opposition to visible-light-induced pigmentation in comparison with untreated pores and skin or mineral SPF 50+ sunscreen in Fitzpatrick IV people,” or individuals with darker pores and skin tones. What’s extra, “these outcomes spotlight that iron-oxide-containing formulation in a basis format have twin features and may present extra advantages in sufferers’ every day routine by masking present pigmentation and stopping the event of pigmentation triggered by daylight publicity, extending safety past the UV spectrum.”

Normally, mineral sunscreens are a better option than their chemical counterparts for anybody coping with melasma or darkish spots, as a result of chemical formulation can inadvertently set off hyperpigmentation. “The mechanism of motion of chemical sunscreens is that they soak up the photo voltaic radiation and rework it into warmth. These particles then grow to be excited, and after they revert again to their un-excited floor state, they may launch warmth onto our pores and skin, and warmth is a identified set off of melasma,” says Dr. Kream. “In contrast to chemical sunscreens, bodily sunscreens don’t soak up UV radiation and dissipate warmth; slightly they may simply replicate the UV radiation.”
Although iron oxide is a mineral blocker, it is not usually used as a stand-alone sunscreen like zinc oxide or titanium dioxide. So whilst you’ll possible see one (or each) of these listed as energetic substances, iron oxides are sometimes listed within the inactive ingredient part.
