Its ability and quality of protection does not degrade over time in the presence of sunlight, so it can help mitigate the breakdown of other UVB isolators in sunscreen to some extent. The product is fresh and non-greasy, and can also convert ingested ultraviolet radiation into less harmful infrared radiation and heat. |
