Sleeping tone-up cream...is it effective?

Sleeping tone-up cream... A tone-up cream you apply before going to sleep...

I found that out recently while watching TV..

I saw a brief clip on a beauty channel?? where celebrities practically advertise it, and it was fascinating.

I looked it up and found there are a lot of products and comments, and people say they are effective...

I'm curious to hear from those who have actually used it..

♧ I wonder if it really has a whitening effect...

♧ If I apply it before bed... how should I wash it off? (I should probably use a facial cleanser the next morning, right?)

I heard it has a variety of benefits, so I'm curious about that too.. (Skin texture improvement, skin barrier strengthening, soothing, moisturizing, etc.)

It's a sleeping tone-up cream, but I'm wondering if it's okay to use it for everyday life...

♧ Please also recommend some sleeping tone-up creams~~
