Signs of Ageing & Photodamage
Skin ageing is a result of biological changes in the epidermis, dermis and hypodermis, extending right down to muscular and skeletal components as natural degradation occurs. In the epidermis, barrier function is reduced causing an increase in transepidermal water loss (TEWL). TEWL is the diffusion of water from the dermis and epidermis which eventually evaporates from the skin, causing dehydration and sensitivities. Skin cell turnover slows, causing rough, uneven texture and pigment production changes, exacerbated by the sun’s harmful UV rays.
