건강힘별이
저도궁금하네요 보관방법 잘몰랏어요
While searching online, I saw a post saying that retinol products need to be refrigerated. I had just been leaving it on my vanity, but oh no... I've used about half of it. Should I put it in the refrigerator now?
Do you all keep your retinol-based cosmetics refrigerated?
Was I the only one using it at room temperature in this sweltering heat?
