Figures & data

Table 1 Old-Age Pathophysiology of the Skin

Anatomical Changes	Clinical Picture
Reducing keratinocyte proliferation	Epidermis thinning
Melanocyte reduction	Decrease tanning capacity and bleaching the hair
Reduction of fibroblasts-collagen atrophy	Vascular Reduction Atrophy-slowing of healing
Reduction of nerve endings	Reduction of sensation
Reduction of sebaceous glands	Reduction of sweat glands
	Risk of heat stroke
Hair loss	Alopecia
Reduction of the fat	Low tolerance to cold- thinning of the face
Delayed growth of nails	Nail diseases
