These cells are densely packed with eleiden, a clear protein rich in lipids, derived from keratohyalin, which gives these cells their transparent (i. e., lucid) appearance and provides a barrier to water. This thin layer of cells is found only in the thick skin of the palms, soles, and digits.
Exposure to the UV rays of the sun or a tanning salon causes melanin to be manufactured and built up in keratinocytes, as sun exposure stimulates keratinocytes to secrete chemicals that stimulate melanocytes. Individuals with albinism tend to need more protection from UV radiation, as they are more prone to sunburns and skin cancer.
