What is “Aged” or “Photo-Aged” Skin?
What is Aged or Photo-Aged Skin?
Here are some of the characteristics of aged skin on a scientific level:
- Aged skin differs from youthful skin both in appearance and function
- Aged skin is thinner (both the epidermis and dermis) and lacks as many keratinocytes
- Aged skin has slower epidermal turnover (reduced by 50%) and impair the skin’s barrier function
- Aged skin has slower wound healing
- Overall, aged skin appears thin, wrinkled, bruised and rough
- The dermis in aged skin produces less collagen, elastin and GAGs (Glycosaminoglycans)
- The aged dermis lacks elasticity, strength, remodelling abilities and ground substance (the matrix surrounding skin cells)
- Melanocytes decrease by 8-20% per decade (less protection against harmful UV rays)
- Stem Cells are still present in aged skin, but it appears they do not function as they once did in our youth – they are les “active”
- To slow down the aging process and delay the need for Laser/surgical Intervention
- Promote thicker, more refined skin by stimulating the formation of collagen, elastin and GAGs in the skin
- Increase the number of “Activated” stem cells in the skin as opposed to “Dormant” Stem Cells
