Has anyone heard doom-and-gloom stories about the potential health dangers of teeny nano particles in their sunscreen? Well I have been concerned about that too so have been keeping my eye on a study by Environmental Working Group. Their latest report says that they expected to find some nasty issues with sunscreens containing nano ingredients BUT.. they actually find that nano products are much safer than any other sunscreen, and in fact they recommend sunscreens containing nano ingredients. As well as containing less harmful ingredients, they give 20% more protection from UVA than any other sunscreen.



SunSCREEN vs SunBLOCK – different..

It is a shockingly widespread belief that sun cream gives you a super-human sun barrier. NOT TRUE!  It is an extremely important part of our skincare routine but certainly not a license to hang out in the sun all day long under the false assumption that we are safe inside an invincible shield

Basic things to know about sun creams:

*Sunscreen and sunblock works differently. Sunscreen contains chemicals which absorb UV. Some people may have an allergic reaction to these chemical absorbers. Sunblock is a physical sun barrier which deflects the sun’s rays. Active mineral ingredients in Sunblock are titanium dioxide and/or zinc oxide.

*SPF (Sunburn Protection Factor). The number on the label is basically a guide to the amount of protection you should have from sunburn. For example. If it takes your skin three minutes to develop a sunburn, and you apply SPF 15 (15×3=45) it will generally take you 45 minutes to develop a sunburn. Needless to say, the effectiveness of a sun cream is relative to your skin’s own natural sun tolerance, HOW MUCH YOU APPLY and to the intensity of the sun (time of day and distance from the equator).

*SPF is a measure for UVB radiation only. There is now a labeling system for the level of UVA radiation protection. Look for the stars on the label. The UK is currently using a FIVE star rating and the US is proposing to upgrade labels to include a FOUR star UVA protection rating alongside the SPF.

*Don’t skimp on the application!-The SPF coverage depends on how much of the cream is applied. Apply a liberal amount to the skin In order to achieve the effectiveness of the SPF on the label.
