I'm 44 and have crepey skin around the top of my cheeks and perioral lines that I'm thinking of having treated with dermaroller or esthelis or other similar hydrating filler. I have very fine skin and had crows feet from 18 years of age and been having botox for the past 18 years. I finished chemo for breast cancer about 3 months ago. I tried having my hair coloured and it went a crazy, unpredictable colour. So I'm worried my skin may also respond to treatment in an unpredictable way.
