oxygen species (ROS) created by UV rays. Vitamin C, vitamin E, silymarin, and green tea polyphenols have all been utilized in sun protective products,3,19 as have botanical extracts which function as anti-inflammatories in sunscreen products such as licorice, aloe, and chamomile.14 While some of these antiinflammatories may decrease skin redness by targeting ROS, they have no impact on the amount of UV radiation hitting the skin, and we should make patients aware of this.
CONCLUSIONS
In conclusion, American sunscreens remain effective at
minimizing sunburn but are more limited in their protection
against UVA mediated skin disorders such as photoaging and
non-melanoma skin cancers compared to certain international
products. Fortunately, mineral blockers which protect against
both UVA and UVB are becoming more widely used as
formulations have been improved. The time has come in this
complex, confusing, and competitive sunscreen market for
dermatologists to take the lead in providing a framework by
which our patients can make informed choices. We provide this
summary as an aid to ensure that we provide our patients with
clear, concise, and helpful information regarding sun protection.
