Worst cosmetics

My worst cosmetic is the Dermaphilia Control Solution Spot Serum.

I'm the type of person who gets frequent breakouts when stressed, so I bought this to soothe my acne, but I didn't see any effect at all.

I tried using it on pimples that were popping up and on scars left after squeezing them, but I couldn't really tell the difference before and after use...

It's good that it's gentle, but since the effects of the functional cosmetic were ambiguous, it didn't feel appealing.

It's hard for a trouble-care product nomad to settle down.
