- How does the dermis of our skin relate to its functions of protection, temperature control, waste removal, water conservation, radiation protection, vitamin production, and environmental responsiveness?How does melanin get into the skin? melanocytes are found in the most superficial layer of skin and are full of melanin giving pigmentation keratinocytes absorb surrounding melanocytes as they rise up from the basal layer to the surface melanocytes form in the basal membrane and as they ascend to the surface they change into keratinocytes while maintaining the original amount of melanin they produced melanocytes in the basal layer produce melanin and inject it into surrounding keratinocytes via the dendritesBriefly describe how melanin provides protection for our skin and describe what physiological and anatomical changes occur to your skin when you have excessive sun exposure.
