how does skin regenerate?

The cells undergo a process known as mitosis. This is when the chromosomes will duplicate themselves and then split into two cells. Hormones often tell cells when to begin mitosis. Your skin grows in 3 layers. The cells towards the inside will multiply and push older skin cells towards the 2nd, and 3rd layer until they die and fall off. This means that your skin in constantly renewing itself.

sandblaster, it really digs out those dead cells\nI always thought eating and exercising better would give you good skin.\nand avoid picking at it or constant squeezing

Its definately the skin. C'mon ppl, Biology 101.

Interestingly enough, when you cut pubic hair, arm or armpit hair or shave legs, the hair grows back to exactly the same length as it was before!\n\nHair follicles in those areas are programmed and have on and off activation.

Grafting is a surgical procedure where a thin layer of skin (autograft) is taken from an unburned part of the body and placed on a burn wound. This helps regenerate a burned area.\n\nPlastic surgery is reconfiguration of the anatomical structure for cosmetic purposes.

It contains small grains which scrub the skin so as to get rid of the dead skin cells. That makes the skin smooth

it is actually depends on which cell we are looking at. most of your body cells except brian cells keep multiplying until a human reach the age of approx 18-19. your upper layer skin cells must be the first one to die approx. 24 hrs or so . your body shed the dead cells and new layers are keep coming from beneath.

Melanocytes (cells in our skin) upon receiving signals of damage to DNA (due to UV radiation) begin producing melanin in large amounts.\nMelanin is a polymer that captures UV and thus protects cells from DNA damage.\nHair doesn't have melanocytes. It is made of keratin (protein) and minerals. So typical reaction will be - no change or in constant exposure to sun rays- damage to keratin and bleaching.

It may never grow back.  Probably won't actually.  If it does start to grow back, it will take several months before it is completely grown out again.

You got it backwards, Vitamin D helps the formation of the skin.

Our skin is the largest organ of our body. Skin serves several functions: it guards the underlying organs and muscles, it regulates our body temperature, it provides our sense of touch and it synthesizes vitamins D and B.\n\nThe skin includes parts like our hair and nails. In addition, there are several layers to skin, e.g., the epidermis and the dermis. Skin accounts for 15% of our body weight so you can see why it's called the largest organ in our body.\n\nThe above is basic information and you can already see how complex skin is. So there's lets to research and talk about when you're talking about skin.\n\nHope this helps.

Superhydrating....Skin has 3 layers. The bottom/lowest/innermost layer is attached to subcutaneous tissues and does not absorb water. The outermost layer absorbs water and when it "prunes" it swells causing the outermost layer to enlarge and wrinkle, while the innermost layer stays the same.

Hair is not repaired after being broken, but if removed it will regenerate, assuming that the folicle hasnt been damanged. The entire hair is composed of dead cells.

How it works\n\nPolysporin* Scar Solution* uses clinically proven silicone sheet technology, the same technology used for years by plastic surgeons and burn centres, to help make old and new scars a more natural colour and reduce their size by mimicking the natural barrier function of normal, healthy skin.\n\ni used to market earlier , it really helps..

No.  Dead stuff doesn't grow.  Instead, what is perceived as "growth" is acually the surrounding tissues receding, or shrinking, as a result of moisture loss from the once living surrounding tissue.  Hair and nails are mostly protein (keratin) and contain very little moisture (in comparison to skin cells) and thus don't shrink.

ES cells have the potential to self-renew, or keep dividing without differentiating into a specific cell type. that means you can coax them to become any kind of cell and keep some going to maintain the pool of stem cells.\n\nso in theory you can make skin for people with burns, new livers, hearts, lungs for people waiting on transplant lists, etc.\n\nthere are adult stem cells you can use as well, but they are hard to get and hard to maintain with current techniques.
