Did you know that your skin cells are constantly being lost and replaced? Old skin cells die off and fall off all the time. A lot of them come off when you take a shower, and many more fall off throughout the day. Not all of them will be lost at once, but bit by bit the cells fall off and then get replaced by new ones. 

How quickly does your entire layer of skin regenerate itself? This happens about once every 27 days, though that number can vary for different people based on different health factors. The skin cell turnover means that we basically get a new layer of skin almost every month. That’s pretty amazing, but there’s more to know about it than just these basic facts. Your skin cell turnover plays an important role in how your skin feels and how healthy it is.

You can improve skin cell turnover

How quickly your skin cells regenerate after they fall off depends on your health and the nutrients your skin is receiving. How can healthy cells replace the old dead ones if there’s no nutrients for them to grow from? Just like a baby needs plenty of milk to grow big and strong, your skin cells will need nutrients in order to regenerate like they should. If the supply of nutrients is very slow getting to the skin cells, then the cells will regenerate slowly.

So, if your skin feels really rough and dry all the time regardless of the weather, you may not be getting enough nutrients to the skin. You can use whitening creams and เซรั่ม in order to nourish your skin cells and provide them with the nutrients that they’re supposed to have. Various serums offer vitamins and minerals that are very healthy for your skin. They can speed up the regeneration process and help ensure that your skin regenerates when it should.

Why doesn’t skin shell regeneration eliminate scars?

If your skin cells are constantly falling off rand then regenerating themselves, then that should get rid of scars, scabs, other imperfections in the skin, shouldn’t it? That might make sense from one viewpoint, but once you realize that your skin’s regeneration uses different building blocks then what scars are made out of, you’ll see why this doesn’t happen.

When your skin cells regenerate, they produce collagen that come from fibroblast cells. This collagen is different from the scar collagen that’s created whenever your skin is damaged. Some of that scar collagen is replaced with regular skin collagen, but sometimes some of the scar collagen sticks around. That’s what leaves scars over time on the skin. Even though new skin cells are being created, they’re having to work around the scar collagen and won’t really interfere with it. 

Damage to the skin often leaves scar tissue behind, and the only time of life that doesn’t happen is during the fetal stage.

In order to remove scars, you may need to use skin whitening serums or undergo a treatment process that removes the skin cells (like micro abrasion). Various treatments can be effective at removing scar tissue or minimizing the appearance of scars to make them less pronounced.

Why do tattoos stick around?

Tattoos work on a different concept than scar tissue. The ink particles used to make tattoos are quite large, and the white blood cells that move through your body and take contaminants away from the skin can’t handle the ink particles. They are simply too big, and the only way to get rid of the ink particles is to use a laser that destroys the ink into particles tiny enough so that white blood cells can do their job.

Your skin cells are an amazing part of your body and its largest organ. The regeneration process is what helps keep skin looking healthy and vibrant even after the skin cells have undergone a lot of abuse. This is why your skin can look great after experiencing rough weather, damage, and other issues. It’s pretty incredible what your body can do on its own without any input from you.
