Instead of using rel="nofollow" you should use rel="me" if you're linking to your own social media pages. This allows you to explicitly tell Google that you're not just linking to those pages, but you actually control them.
By placing ‘rel=me’ attributes on all your links to your social media profiles (from your own website), it will help search engines like Google understand and have confidence that your social profiles are actually your brand.
