The transmission rate of keratin in 222nm deep ultraviolet light is only 0.01%, and it cannot penetrate the skin cuticle, so it does not cause skin aging or skin cancer.
However, conventional 254nm uv penetrates the upper epidermis, 300nm uv penetrates the all-important basal layer of the epidermis and causes DNA mutations, and 340nm, 360nm and 400nm uv penetrates the dermis.
The transmission rate of 222nm uv rays to the cornea is only 0.01%, and it does not penetrate the tear layer of the eye, so it does not cause keratitis or cataracts.
Whereas conventional uv at 254nm penetrates through the epithelial and stromal layers and even penetrates into endothelial cells, uv at 300nm penetrates through the lens, reaching the germinal layer of the lens and causing DNA mutations.
