What's one skincare myth clients still believe that drives you crazy?

I feel like skincare misinformation is everywhere now, especially on TikTok and Instagram.

For those of you who work with clients regularly, what's the one myth you find yourself correcting over and over again?

Could be about acne, sunscreen, exfoliation, anti-aging, facials, or anything else.

I'm curious which misconceptions just never seem to go away.
