Dr. Sukran has been my anti-aging specialist for a few years now. I go to her for regular Botox injections and had fillers all over my face. She's the best! she's professional, talented and the sweetest doctor you can ask her. She would not let you get any treatment unless it's necessary, even for esthetic purposes. It's not easy to find a doctor like that in this field.
If you use a Dermapen suitable for use at home, you can. This will increase the absorption of the product, hence the effectiveness. However you should be more careful using sun block. Also do not use your Dermapen more than once or twice a week to prevent irritation (which may cause pigmentation) in summer.
