Chemical sunscreen ingredients also mainly work by absorbing the UV rays. [8] Over the years, some organic UV absorbers have been heavily scrutinised to assess their toxicity [9] and a few of them have been banned in places such as Hawaii [10] and Thailand [11] for their impact on aquatic life and the environment.
Ultraviolet radiation is known to suppress the immune system and reduce inflammatory responses. Light therapy for skin conditions like psoriasis usually use 313 nanometer UVB though it may use UVA (315–400 nm wavelength) or a broader spectrum UVB (280–315 nm wavelength). UVA combined with psoralen, a drug taken orally, is known as PUVA ...
Sunscreens are utilized to secure the skin from the destructive impacts of ultraviolet radiation from the sun. UVB (290-320 nm) together with UVA-2 (320–340 nm) and UVA-1 (340–400 nm) cause organic and metabolic reactions in the skin.
