I understand that and I know that problem skin can as a teenager can last into adulthood, regardless of what products are used. My issue with her is that I have seen her showing off how amazing the Kiehl's products are for a swipe up when she's clearly not showing her true skin, it's either with makeup on or filtered.
So essentially she's using makeup and filters to demonstrate how good the Kiehl's stuff is but then showing her true skin as a "before" to demonstrate the YSL product that is amazing on covering up her problem skin!
The Kiehl's stuff is expensive and it's not giving her the complexion that she sometimes claims it is.
But then again, she's not transparent at all with anything- look at how she became an ambassador for Skinny Coffee when she actually lost her weight with SW
