Dermaquest Sheer Zinc SPF 30, Tan 56.7g

Who it's for 
Very dark, type III or IV skin types. Tan is ideal for dark skin tones where paler sunblocks will be visible with a bluish sheen. Also suitable for oily, breakout prone skin as it is very light and the finish is matte. Particularly useful for topping up over make up. 

Dr Coleman's review
This fantastic block contains 18.6% Zinc Oxide with added Iron Oxide to give the colour and this provides further protection against visible light and pigmentation. This Dermaquest range is my hero sunblock, especially for people prone to pigmentation. Zinc oxide blocks UVA and UVB rays and antioxidant-enriched vitamin E banishes free radicals for complete protection from environmental aggravators. Ferric (iron) oxide blocks visible light. The sheer tinted formula is absorbed easily, infusing skin with moisture for a comfortable wear and lovely smooth finish. Make up sits nicely over it.

However, remember that it isn't a moisturiser so for added protection, apply over your moisturiser containing at least SPF 30 eg Revision Multiprotection SPF50 (now known as Intellishade Clear) or Skinceuticals ultra facial defence.

How to use
Apply to the face, neck, and décolleté as desired throughout the day.
