Skin tissue can be regenerated in vivo or in vitro. Other organs and body parts that have been procured to regenerate include: penis, fats, vagina, brain tissue, thymus, and a scaled down human heart. One goal of scientists is to induce full regeneration in more human organs. There are various techniques that can induce regeneration.
In the event of an injury that damages the skin's protective barrier, the body triggers a response called wound healing. After hemostasis, inflammation white blood cells, including phagocytic macrophages arrive at the injury site. Once the invading microorganisms have been brought under control, the skin proceeds to heal itself.
Human skin pigmentation varies substantially between populations; this has led to the classification of people(s) on the basis of skin colour. [ 3 ] In terms of surface area, the skin is the second largest organ in the human body (the inside of the small intestine is 15 to 20 times larger).
“Dry skin can start premature aging, so keeping the skin hydrated with a moisturizer is key,” says Dr. Engelman. She adds that skin regenerates mostly between 10 p.m. and 2 a.m., as we sleep.
Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. [1] Every species is capable of regeneration, from bacteria to humans.
The use of fish skin with its natural constituent of omega 3, has been developed by an Icelandic company Kereceis. [50] Omega 3 is a natural anti-inflammatory, and the fish skin material acts as a scaffold for cell regeneration. [51] [52] In 2016 their product Omega3 Wound was approved by the FDA for the treatment of chronic wounds and burns. [51]
Both Dr. Chaudhry and Holdorf recommend PCA Skin's anti-aging serums to target several of the most common signs of mature skin: dryness, sensitivity, wrinkles, fine lines, age spots and thinning skin.
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
