If sunscreens were regulated as cosmetics, we would have had by now an efficient set of safe and effective ultraviolet filters that would have afforded our consumers much better protection particularly from the now well-documented harmful UVA radiation. That decision, apparently, is not forthcoming soon and, unfortunately, the FDA is reluctant to allow the reclassification of sunscreens as "cosmetics" even though they are mandated to enforce cosmetic regulations.
UVA radiation can penetrate glass so suncream should be applied before long car journeys or sitting by sunny windows.
The stars range from 0-5 and indicate the percentage of UVA radiation absorbed by the sunscreen in comparison to UVB.
The UVA (320-400 nm) and UVB (290-320 nm) wavelengths that act in the skin cause effects such as photoaging, photosensitivity (DNA damage), appearance of wrinkles, and a series of cellular alterations involving fibroblasts and melanocytes due to UVA radiation, which possesses a greater power to penetrate the skin.
(6,25) While this helps prevent sunburn, it does nothing to block the UVA radiation that makes up 95% of ultraviolet radiation and causes much greater damage.

UVA radiation is penetrative and reaches targets well below the skin surface, acting on the basal layer of the epidermis, where proliferating keratinocytes reside [3].

The UVA radiation in its chamber at the surface of patient's skin was 4 mW/cm2 and for UVB the radiation was 1.25 mW/cm2.
To conduct the study, researchers measured outside ambient UVA radiation as well as UVA radiation behind the front windshield and behind the driver's side window in 29 vehicles from 15 manufacturers.
