Katherine Daniels is a British skin care range which has been developed by Kirsti Shuba and Donna Tait, who impressively have over 60 years of beauty therapy experience between them. I have previously tried out their Essential Exfoliating Gel which was great (super gentle and used kind of like a mask), so I jumped at the chance to try out this product, the Urban Shield Concentrate* - which is a favourite of Courtney Cox's, which gave me complete faith it in straight away - if it's good enough for her, it's good enough for me! (And her skin is amazing!).
