It is encouraging to see fewer sunscreen allergy side effects due to an increasing number of effective sunscreens being developed. However, these are few, amidst the vast array of sunscreens available today and so it pays to be diligent when it comes to understanding the possible causes of sunscreen allergy. Research over the last decade or so has revealed the importance of protecting against UVA rays and not just UVB. Alongside this, it has become evident that the chemical sunscreen filters used to obtain high SPF (UVB spectrum mainly) do not offer high protection for UVA rays. Also, the one chemical sunscreen that does offer high UVA protection photo-degrades after a mere 8 minutes exposure to the sunlight. - See more at: http://www.natural-organic-sunscreen.com/sunscreen-allergy.html#sthash.RCLSxyJp.dpuf
