- Skin is the body’s largest organ that has multiple layers.
- It protects the underlying organs, prevents water loss, plays role in temperature regulation, absorption, sensation and synthesis of Vitamin D.
- Skin is composed of 3 layers: epidermis, dermis, hypodermis or fatty tissue
- The epidermis contains 4 main cell types: keratinocytes (barrier against environment), melanocytes (skin color cells), Langerhans cells (protect skin against bacteria) and Merkels cells (sensation cells).
- The dermis is important in developing sensation and cushions the body against external stresses. Structural components of the dermis include lymphatic and blood vessels, collagen (provides strengths), elastic fibers (make skin stretchable), nerve ending, hair follicles, sweat glands and (oil production) glands.
- The hypodermis layer mainly plays role in fat storage. The main cells of the hypodermis are adipose (fatty) cells, fibroblasts (make cologen and heal wounds) and macrophages (protect skin against infection).
Understand Skin Aging
Ageing is a natural process that involves complex interaction between the environment, lifestyle and the genes.
Skin changes caused by ageing include:
- Thinning the cell turn over slows down.
- Sagging – as less of elastin and collagen is produced the skin becomes more vulnerable to effects of gravity.
- Wrinkles – reduced elastin and collagen and the thinning of skin…..
- Pigmentation – the pigment cells (melanocytes) tend to increase in number and cluster in certain areas in areas that are exposed to the sun.
- Dryness – older skin has fewer sweat glands and oil glands.
- Broken blood vessels – as the skin gets thinner the blood vessels tend to break and bruise more easily.
Ways to slow down the skin ageing
- Limit sun exposure and use sunscreen, at least SPF30.
- Don’t smoke as smoking causes cell damage and earlier wrinkling of the skin.
- Use good skin care regime. Well-balanced skin stays young for longer.
- Eat well, drink plenty of water, drink sensibly and stay active to slow down the aging.
