Constant regeneration of the skin is achieved due to stem cell differentiation within the epidermis and the hair follicle; thus, skin may serve as an excellent source of stem cells. This is of paramount importance in the treatment of chronic skin wounds and burns.
In order to make collagen, you need vitamin C. Eating foods with vitamin C can promote skin healing by stimulating new skin cells to grow in the damaged area. In addition to this, vitamin C can also help the healing process by building new protein for the skin, scar tissue, tendons, ligaments and blood vessels.
Ageing and Skin Renewal Process
In babies, the skin renews itself every 14 days. In teenagers, this process takes about 28 days. In adults, it takes between 28 and 42 days. In those age 50 and older, the skin renewal process can take up to 84 days.
The epidermis constantly renews itself: New cells are made in the lower layers of the epidermis. These move to the surface within four weeks. This constant renewal serves to replace the cells that are lost and fall to the ground as tiny flakes of skin when the skin is rubbed.
If you're average, your skin weighs about six pounds. It's job is crucial: to protect you from infections and germs. Throughout your life, your skin will change constantly, for better or worse. In fact, your skin will regenerate itself approximately every 27 days.
Vitamin C, also known as ascorbic acid, is required for the synthesis of collagen. It is also a highly effective antioxidant protecting cells from damage by free radicals. Studies have shown that the vitamin can help speed the healing process of wounds.
Vitamin A, vitamin C and zinc help your body to repair tissue damage, fight infections, and keep your skin healthy. Try to eat foods from the lists below. Vitamin A is found in animal foods and some brightly coloured vegetables and fruits. Many vegetables and fruits are high in vitamin C.
The cells in the superficial or upper layers of skin, known as the epidermis, are constantly replacing themselves. This process of renewal is basically exfoliation (shedding) of the epidermis. But the deeper layers of skin, called the dermis, do not go through this cellular turnover and so do not replace themselves.
Home remedies. First, gently clean the skin tear with a sterile water or isotonic saline solution. If it's a smaller and more superficial tear, a gentle soap and water may be used. Then fully cover the tear, but don't use an adhesive bandage directly on the wound.
Zinc, a cofactor in the production of collagen, plays a vital role in collagen synthesis. This mineral is essential to cell repair and helps protect collagen in the body from damage. Zinc deficiency can reduce the amount of collagen produced, therefore getting adequate amounts is important!
So caffeine is a collagen killer and we should steer clear? Not exactly. "It's worth remembering that coffee doesn't destroy collagen, it inhibits its production," says nutritional therapist at the Pulse Light Clinic, Lisa Borg.
“And free radicals are the big culprits that destroy collagen, and therefore, lead to the appearance of lines and wrinkles.” For an antioxidant serum adored by AW – and dermatologists, for that matter – try SkinCeuticals CE Ferulic.
Just like aloe can heal your skin after hours in the sun, it can also heal your skin in other ways. "It contains anti-inflammatory chemical compounds — which reduce swelling — called anthraquinones. These chemical compounds promote healing and alleviate pain when applied to your skin.
Fruit Juice
Drinks like orange and tomato juice are an excellent source of vitamin C, which can work in tandem with collagen to revitalize your skin. If you're worried about these juices' higher acidity eroding your tooth enamel or causing heartburn or acid reflux, it's best to consume them in moderation.
Consuming omega-3, green tea antioxidants, and turmeric can also help prevent dry skin.
