Hi the Beauty brains,
I know you guys are expert in dermatologists. I know from your podcast that the best moisturizing ingredients are petroleum, mineral oils. But only using petroleum as moisturizer is too greasy. What do we need to take into account besides the moisturizing agents? And I heard of some information that young adults are encouraged to use anti aging products. Is it true to better use anti aging moisturizer, for example containing retinoid and vitamin C? Thank you!
