The main concern is getting the correct concentration of UVA / UVB sunscreen on your skin.
Many combined products don't have enough sunscreen to be effective.
To achieve the advertised level of SPF you need to use two milligrams of sunscreen per square centimeter of skin - which is quite a generous amount of product.
Most commercially available High St or department store combined moisturisers with spf (sun protection factor) just don't contain enough sunscreen to be effective without you using so much product that you'd look like you'd had a custard pie in your face!
So if you do want to use a combined product you need a clinical or cosmeceutical grade product. You are looking for Zinc Oxide and Titanium Dioxide which are physical sunscreens. They are minerals which act like reflectors on the skin rather than chemicals which can penetrate the skin and can cause irritation.
Ranges by Medik8, Heliocare Cream, Circadia by Dr Pugliese and Image - for example, do offer excellent products with the correct concentration of physical suncreen for an elegant aesthetic.
World leaders in skin health protection - Skinceuticals - don't offer a combined product as they promote the layering system of penetrating serums, protecting hydrators and elegant physical suncreens on top.
It's down to personal choice BUT do choose a clinical or cosmeceutical grade product range with evidence based documentation to support them.
My personal favourites are:
* Image Daily Defense range SPF 30 & 35 - combined
* Medik8 Hydr8 SPF 25 - combined
* Circadia Light Day Cream SPF 30 - combined
* Heliocare Cream SPF 50 & 90 - combined
* Skinceuticals Sheer Mineral Defense SPF 50 - excellent, soothing, sheer, silky, sits beautifully over any moisturiser and makes an excellent base for make up
If you choose a combined Sunscreen and moisturiser you really should use a different cream at night -
Lastly - don't think of sunscreen just as a defense from the hot sun............they should be called LIGHTSCREEN or UV Screen because all light is potentially damaging and ageing to the skin....................even our dull days here in Manchester.
UVA light - A for Ageing......passes through glass too.
Britain has a VERY high incidence of skin cancer which could be reduced just by regular use of sunscreen (and antioxidant serums) !
