She kept stealing my skincare, so I let her glow up the hard way

My sister in law was staying with us for a bit and decided my bathroom was her personal Sephora. Every morning, I’d notice my skincare products getting lighter, but she’d always deny using them like I’m blind and dumb. So I swapped out the label on a nearly serum bottle with a similar looking one I use for my keratosis, super strong, smells fine, burns like hell if misused.

Next morning, she’s blotchy, orange tinted, and low key panicking in the mirror. I hit her with the innocent “oh no, did you try something new?”, she said “what? No! I mean… I might’ve used that a little bottle, but I thought it was like… for everyone?” *nervous laugh, and “ohh… yeah no. That’s prescription. Definitely not a for everyone kinda thing. Maybe next time just ask?” I says. Then I walked out and let her sit with that.

After that, she never touched my stuff again and suddenly respects the concept of personal property.
