1. What does it mean?
쌩얼 is a colloquial spelling used for 생얼, a face without makeup. It appears in casual conversation, selfies, and entertainment captions when someone is describing going out or appearing on camera without their usual cosmetics.
Also written or said as 생얼, ssaengeol
2. The nuance
A photo labeled 쌩얼 does not prove the absence of filters, editing, or every cosmetic product. It is a description, not a measure of beauty or honesty.
3. Examples
“편의점에 잠깐 가는 거라 쌩얼로 나왔어.”
I was only going to the convenience store, so I went out without makeup.
“쌩얼 사진을 올릴지는 내가 정할게.”
I'll decide whether to post a bare-face photo.
