Rihanna called out an Instagram commenter's 'ignorance' after they poked fun at a photo of her wearing sunscreen indoors

• Rihanna posted a selfie on Sunday that showed her wearing a pink bra, Yankees bucket hat, and sunscreen from Fenty Skin.
• When an Instagram commenter implied that she didn't need the skin-care product now that summer is over, Rihanna replied and pointed out their "ignorance."
• She also said they would develop wrinkles if they "think SPF is seasonal."
• Dermatologists often advise people to wear sunscreen every day, even when it's cloudy or you stay indoors.

As the founder of Fenty Skin, Rihanna knows a thing or two about skin care — so you probably shouldn't question her personal routine.

On Sunday, the makeup mogul took to Instagram with a photo of herself wearing a pink lace bra and Yankees bucket hat. The latter accessory was so oversized that its rim hung over her eyes and above her cheeks, where she wore two streaks of her brand's Hydra Vizor Invisible Moisturizer with Broad Spectrum SPF 30.

In the caption of her Instagram post, Rihanna tagged Fenty Skin and wrote: "just protecting my melanin while they try to eradicate it!"

But when an Instagram commenter poked fun at the fact that she was wearing sunscreen, Rihanna was quick to respond.

"It's winter now," an Instagram user wrote, seemingly saying that Rihanna doesn't need sunscreen now that summer is over.

Rihanna replied to their message, saying: "It's the ignorance for me! You gon have wrinkles if you think SPF is seasonal! But continue."

Though Rihanna's Instagram comment was likely written in jest, the musician is smart to wear sunscreen throughout every season.

According to dermatologists, wearing sunscreen when you go outside year-round is important because things like driving and taking certain medications such as retinol can put you at higher risk of getting sunburned, even on cloudy days.

Dermatologist Marisa Garshick previously told Insider that it's important to reapply sunscreen multiple times each day — even if you're staying indoors.

"I always tell my patients that even on a normal routine day, it is important to be reapplying, every day, every two hours, even if somebody is just in the office or going for a walk," Garshick said.
