How Much Blush Is Too Much?

Jennie Suk, 27, has gotten really into wearing blush in recent months, inspired by videos from TikTok influencers and celebrities, like the singer Sabrina Carpenter, whose dewy, flushed cheeks have become her calling card.

Drawing from her personal arsenal of about 25 blushes, Ms. Suk says she enjoys experimenting with layers of different creams and powders for a rosy glow.

“A couple years ago, I probably only had one or two blushes — I would rarely use it,” said Ms. Suk, who lives in Houston and works in social media for a veterinary services company. “Now I can’t leave the house without blush on.”

She found herself using more and more products, until someone finally pointed out that she might be using a bit too much. On social media, this affliction — not being able to tell, empirically, how rosy is too rosy — has jokingly become known as “blush blindness.”

“I first realized that I kind of had blush blindness when I walked into my sister’s house and she was like, ‘Oh, did you get a facial? Because your face is so red,’” she recalled.

Being called out for having blush blindness has women like Ms. Suk reconsidering how much of the product they are wearing. (It is a spinoff of another TikTok trend, eyebrow blindness, in which users post self-deprecating photos of their old eyebrow styles.)
