Rant about "Sephora kids"

why are some people hating on 10 year olds with skincare??? like I get it if the kid is using anti-aging products and hasn't hit puberty, (even then its unacceptable, like ur bullying a kid go get a life babe) but me and my sister hit puberty at eight and nine years old and broke out like crazyyyy and needed to use skincare because omg it was BAD, not as bad for me, but my sister had cystic acne (is that how u spell it??) and we needed it bad because sometimes those pimples HURT. and it makes me so sad seeing people hate on kids with skincare.
