Dark skin gives seven to eightfold protection against DNA damage, but even the darkest skin colour cannot protect against all damage to DNA. Dark skin offers great protection against UVR because of its eumelanin content, the UVR-absorbing capabilities of large melanosomes, and because eumelanin can be mobilized faster and brought to the surface of the skin from the depths of the epidermis. For the same body region, light- and dark-skinned individuals have similar numbers of melanocytes (there is considerable variation between different body regions), but pigment-containing organelles, called melanosomes, are larger and more numerous in dark-skinned individuals.

Baumann Skin Types form of post-inflammatory hyperpigmentation (PIH). Most pigment changes can be prevented and corrected through the use of proper skincare ingredients. Age, ethnicity and lifestyle habits influence whether skin is wrinkle-prone or tight. There is still a genetic component to this parameter, but external factors that contribute to an aged appearance are controllable. Sun exposure is the primary cause of skin aging, destroying skin proteins like collagen and elastin. Each parameter is associated with particular skin conditions and challenges, and the specific combinations also experience particular tendencies. For example, DRPW types often have a history of sun exposure manifested by wrinkles
