What causes a sunscreen rash?

Sunscreen rashes are a type of contact allergy. In keeping with NYC board-certified dermatologist Hadley King, MD-FAAD, two issues could cause sunscreen-related breakouts: occlusion of the pores by comedogenic supplies or a sensitivity response to chemical UV-blocking components. “And take into account that breakouts can come from any of the components within the product, not solely from the lively sunscreen components,” she says. “Breakouts can generally be attributable to different emollients, fragrances, preservatives, or different components.” Due to this, she says that the easiest way to keep away from growing a breakout or rash from sunscreen is to search for formulation labeled as non-comedogenic. Typically talking, she says that zinc oxide and titanium dioxide (each of that are mineral sunscreens) are each non-comedogenic.

The difficulty with sunscreen rashes is that they don’t all the time current instantly, which might make it tough to establish the true complexion perpetrator. “It’s a delayed pores and skin response that sometimes develops 12 to 72 hours after publicity,” King says.

What does a sunscreen rash appear like?

Sunscreen rashes can tackle a few varieties. On one hand, they’ll seem as tiny white pustule breakouts because of pore-clogging components within the SPF; on the opposite, they’ll appear like conventional infected rashes. (FYI: Should you develop full-on solar blisters, the solar itself is extra more likely to be the trigger than your SPF.)

“More often than not [true sunscreen rashes] will seem as a pink to purple rash composed of small bumps coalescing into bigger bumps,” says Schweiger Dermatology Group board-certified dermatologist Nava Greenfield, MD.

Most significantly, sunscreen rashes will solely seem when sunscreen was really utilized. So should you solely utilized SPF in your physique however your face is breaking out, the sunscreen isn’t responsible.

“As with most varieties of contact dermatitis, an allergy from sunscreen ought to have a pointy line of demarcation,” says board-certified dermatologist Dustin Portela, DO, FAAD. “This implies it’s usually very clear the place you utilized it and the place you missed making use of it by the abrupt geographic sample of the rash.”

What must you do should you get a rash from sunscreen?

Should you decide that the breakout or rash you’re experiencing is from the sunscreen you used, cease utilizing it instantly.

Earlier than tossing the rash-causing components, although, Portela suggests scouring the label. “You will need to test the label and decide what sort of sunscreen you’re utilizing,” he says. “Though sunscreens are protected, there are a small proportion of people that might have an allergic response to a number of the components.”

Typically, he says that chemical sunscreens are typically extra triggering than bodily ones. “The lively components in a chemical sunscreen are sometimes issues like octinoxate, homosalate, octocrylene, oxybenzone, and avobenzone,” he says. “In case you are utilizing a chemical sunscreen and develop a rash, I like to recommend switching to a bodily sunscreen with lively components like zinc oxide and titanium dioxide.” These bodily (and reef-friendly!) components are typically gentler, which is why they’re usually present in child sunscreens.

Whereas sunscreen rashes are most frequently linked to the UV-protecting components, King says that an opposed response to SPF may also happen if the product is expired. “If the sunscreen has expired or the components have been uncovered to direct daylight and excessive temperatures, then the warmth and solar can break down the chemical substances and render them ineffective and doubtlessly irritating to the pores and skin,” she says. That’s why most sunscreen bottles and tubes explicitly say to maintain them out of direct daylight and saved in a cool, dry place.

How lengthy does it take for a sunscreen rash to go away?

Sunscreen rashes can disappear inside days to a few weeks. To supply your infected pores and skin some reduction within the interim, King says to scrub your face and/or physique and observe up with an emollient to assist assist the pores and skin barrier. In case your pores and skin is especially itchy, she says to succeed in for OTC hydrocortisone. (When you might really feel inclined to attempt Benadryl to alleviate your signs, Portela says it received’t do a lot to deal with the underlying reason for the rash, although it may make falling asleep with an itchy pores and skin concern a bit simpler.)

If after two weeks you’re nonetheless experiencing redness and/or itchiness in areas the place you had utilized sunscreen, seek the advice of your physician for finest subsequent steps.

keep away from growing a rash from sunscreen

When you have notably reactive pores and skin, you might wish to skip out on one class of SPF general. As we talked about above, chemical sunscreens are typically extra triggering than bodily UV blockers. Right here’s why: “Chemical sunscreen components are absorbed into the pores and skin whereas mineral bodily blockers sit on prime of the pores and skin,” King says. “I believe that is one purpose the chemical components usually tend to trigger reactions.”

Of the assorted chemical sunscreen components in the marketplace, King says that oxybenzone is among the most problematic. “It has been linked to irritation, sensitization, and allergy symptoms,” she reveals. (Because of this many chemical sunscreens, just like the Shiseido Clear Sunscreen Stick SPF 50+ ($30), particularly market themselves as “oxybenzone-free.”)

Particular chemical components apart, Greenfield says that chemical SPF components usually are sometimes paired with extra preservatives to make the general components extra secure. The draw back is that these preservatives could cause opposed pores and skin reactions, which might present up within the type of a rash from sunscreen.

Due to this, you might wish to solely go for mineral sunscreens. Nonetheless, based on Portela, that’s actually not essential—except you’ll be able to unequivocally decide that the chemical components are the difficulty. It’s very potential that your pores and skin merely doesn’t jive with the opposite components within the general components. As such, your finest guess is to search for top-rated SPFs and to all the time carry out a swatch check on a small space of pores and skin earlier than making use of the product to your face or throughout your physique.

The excellent news is that there are such a lot of dermatologist-approved sunscreen formulation to select from for face and physique. You may even discover SPF in make-up and skin-care merchandise.
