what are primary lesions?
early stage of development, flat, non-palpable changes in skin color or elevation with fluid.

immediately after an injury. vasoconstriction happens for few minutes, which gets the bleeding under control, followed by couple days of vasodilation that allows to buildup of cells needed to repair the deeper wounds.
what are tertiary lesions?
vascular, involving blood or circulatory system

hypo: albinism, vitiligo, leukoderma
what is the % of the skin cancers caused by sun exposure?
over 90%
what is a final phase of wound healing and when does it happen?
maturation phase or remodeling, between 3-6 weeks to a year after the injury
what is dermatoheliosis?
long term damage to the skin cause by UV light
