I find his acceptance and normalization of cosmetic surgeries and using photo editing like facetune to completely alter the structure of your body is the most damaging to his young audience. 

Not saying he shouldn't do what he wants, but it will probably damage some of  his viewers image of themselves and their idea of normal beauty. I can't imagine being a teen girl in this age of Instagram models and "influencers". 

Do what makes you happy, but lip filler will not fix your relationships and shitty personality.
