My favourite sunscreen this year is from Elta MD.  Sunscreens improve every year it seems, as technology advances.  I love it because my clients are now compliant with wearing sunscreen and it offers great protection from both UVA and UVB rays.  The UVA rays are the rays that can pass through clouds, glass, smog, etc.  These are the aging rays and require a physical block such as zinc oxide or titanium dioxide.  Elta MD has formulated a micronized 9% zinc oxide, which is not heavy in the feel or look or smell.  The SPF ranges from 40 to 50 and this is excellent UVB protection.
 
The Elta MD UV Daily is great for normal to combination skin and has anti-aging hyaluronic acid and is also paraben-free.  Elta MD UV Shield is great for oily and acne-prone skin.  Elta MD sunscreens are 20% off this month at Glow Medi Spa.
