I didn't tell my husband when I first got it just because I was curious if he would notice anything's different or if he would find me strange looking. I figured if he never notices it then there's no chance anyone else will as he spends the most time with me.I'm intrigued why he doesn't know?
He never noticed, however one morning when we woke up and were still in bed he did comment that I look really cute and "youthful" (in our language it sounded cute not creepy hahaha). So I guess it was working.
Now I just tell anyone I talk to about skin / skincare.
