The answers below are a result of my own research and my own experience as a long time, pleased, foreskin restorer. Some information is an excerpt from a university biology instructor that is also a FS restorer.

Q: How does un-circumcision actually come about?

A: Skin cells replace themselves every 24 - 36 hours. After a cell divides, the original cell dies off. When skin is stretched for any period of time, the skin cells react by accelerating their rate of division. The increase in the division rate is due to the cells rushing to fill the gaps between them when the skin is stretched. Soft skin, such as eyelids or the skin on a penis, is more receptive to actually expanding and staying in the stretched position.

Here is a numeric example of the acceleration rate of skin when stretched. The numbers here are not exact and are used only to make a point. Let us say that there are 1,000 cells per square inch of skin. In 24 hours these cells would have started and finished reproducing themselves. When we stretch the skin and create gaps between them, the cells react. They are used to a certain density and now that has changed. Each of those cells starts to divide again right away.

Since we started with 1,000 and assumed that they were already in the division cycle, we now have 2,000 in that same square inch. These cells are preparing to fill in the gaps at an accelerated rated actually giving us 4,000 living cells per square inch over the next 24 hours. However, since the original 1,000 cells have died off we end up with 3,000 new cells. These numbers are fictitious. We all know that there are many more cells in every square inch.

What happens to those 3,000 new cells? They live on and start to reproduce themselves as normal. Since they used to have a certain amount of space between them, they push and shove and make more room for themselves by expanding the skin.

Tissue expansion only happens at an accelerated rate when the cells are put under tension. They would be happy going on and reproducing at their normal rate. As foreskin restorers, we are trying to gain more skin. By not putting new or more tension on the skin cells every 24 hours, we are actually doing ourselves a disservice. Think about it, the cells rush to fill the gaps, once the gaps are filled there is no reason for them to reproduce at an accelerated rate. Also, if you stretched your skin for 4 hours, all of those new cells have been produced and will continue to live whether or not they are still stretched.

Skin, like most organs, is 3-dimensional and therefore not just a single layer. Most importantly, not all layers of skin cells divide. In fact, only a small percentage actually have that capability. Skin (I'll focus on the outer FS for now) is actually made of two distinct layers: 1) epidermis and 2) dermis. The epidermis (even in relatively thin skin such as the outer FS) has its own layers of cells in various stages of development. I'll mention only the outermost and innermost here. The outermost epidermal layer consists of 20-30 layers of DEAD cells which clearly don't divide. Down deep (in reality just a few mm from the surface) is a thin layer of epidermal "stem cells", whose soul purpose is divide and create new "skin" cells. These cell offspring gradually work their way upward to replace the dead surface cells that are worn away.

My point is that skin expansion through stretching does not simply induce all skin cells to divide and fill in a 2-dimensional space, but rather causes a minority of deep "stem cells" to divide to begin filling the voids. Seen in this view, it's perhaps easier to understand why the process takes so long. Filling a 3-dimensional space takes much more time and materials (cells) than a 2-dimensional space.

This also raises the issue of how long should the stretch be? If the skin is stretched only long enough to induce the "stem cell" to divide and then allowed to return to its normal position, where do the new "offspring" cells go as they try to make their normal journey upward? This perhaps explains why prolonged (but moderate) stretching is the optimal method for skin expansion.

I have learned to tape for 7 - 8 hours a day giving the cells plenty of time to fill the gaps. Guys wanting to tape for 24/7 should at least re-tape 24/1 or find a way to increase the stretching so that the cells will feel the need to accelerate their division again.

Q: How long will it take to un-circumcise myself?

A: That depends on your goals. Some men do it for looser skin on their penis to relieve friction during erections and sexual activity. Some want to cover their glans to restore it to its original condition, not callused from rubbing on their clothing.

The benefit of having loose skin on your penis during intercourse or masturbation is the "gliding" feeling restored men talk about (yep that's me in 2000). Many men say that the extra skin reduces the friction during intercourse, allowing them to last longer (not ejaculate too soon), which of course allows their partner to reach her plateau.

Many men develop looser skin within 3 - 4 months of constant stretching. Constant stretching means daily, not 24 hours a day 7 days a week. Complete coverage can take 2 - 3 years. The motivation to continue on to complete coverage is driven by the pleasure experienced after the first few months.

Q: Am I really restoring my foreskin or just stretching skin?

A: You cannot restore your foreskin to manufacturer’s specifications. You will notice that when comparing pictures of un-cut males and restored males, the un-cut skin is thin and clings to the glans. The restored foreskin is a little puffy and may be a little baggy around the frenulum.

The puffiness comes from not being able to completely control the direction in which the skin is expanded. The bagginess can be controlled by focusing on stretching inner foreskin. Focusing on the inner skin will help the expanded skin cling to the glans.

Though many nerves are cut away by circumcision, many are stretched with the skin as it starts covering the glans. My restored foreskin certainly has nerves. The lack of nerves would mean no sensitivity in the skin. When I pinch my foreskin I get real sensation like pinching any other skin on my body. Is my foreskin original? No. Is it functional? Yes.

Q: What is inner foreskin?

A: Inner foreskin is the skin that comes in contact with the glans as the foreskin covers it. The dark band of skin around penis is the circumcision scar. On circumcised men, the inner foreskin is the lighter colored skin between the circ scar and corona. Some men can actually see their circ scar. Under close examination, I can see some of my scar. It looks like a thin line about the size of fishing line.

Q: So what kind of technique should I use to restore my foreskin?

A: As you can see by this picture, blood vessels and other tissues are involved with tissue expansion. Any device that compresses skin between hard surfaces should be avoided. The blood vessels, nerves and other tissues are compressed, limiting the growth of these cells and tissue. This could cause scar tissue to develop. Think about it, you are cutting off blood flow to crushed blood vessels and reliant tissue.

I usually attach my devices with a tape-ring (t-tape would serve the same purpose). I do wear a cone that sandwiches the skin against a hard surface, but only for a couple of hours at a time between longer term tapping methods and going to the gym or marital affairs.

Q: When I remove the tape from my shaft skin I have soreness and abrasions. What’s going on?

A: Try "peeling" the skin away from the tape as opposed to "pulling" the tape away from the skin. Many men take the tape off in the shower since one of the most used tapes in 3M Micropore and it is not waterproof.
