It’s one of the easiest things to skip, especially at night.


After a long day at work, running the kids here and there and everywhere, cooking dinner and shovelling it down, and then off again, the only thing you want to do is fall in your nice, comfortable, warm bed and regenerate. The last thing you want to do is your nightly skin care routine. Furthermore, your morning skin care routine may be cut short as well, skipped when you hit the snooze button 10 times instead.


MDPen, a leader in microneedling devices and provider of microneedling equipment to practitioners, is here to tell you not to make that mistake. Skin care needs to be a priority, similar to all other aspects of your health and wellness such as exercise and diet and nutrition. MDPen’s offers proprietary skin care products that include our Cellular Renewal Serum. All of our skin care products are vegan formulations containing organic ingredients that are paraben, petrochemical and SLS/SLE free, and are never tested on animals.




The human body contains about 10 trillion individual cells. The cells in our bodies are constantly dividing, regenerating, and dying, but each cell’s life cycle is different. Some renew themselves often like skin cells and blood cells. However, some don’t renew either at all or very, very slowly such as brain cells.

Like everything with age, cellular turnover slows, dividing and replacing themselves less quickly and less efficiently. Eventually the rate of dying cells outpaces the rate of new cells being produced. Our epidermal skin cells (the outside layer of skin we touch every day) renews itself every 10-30 days (which should explain why you have to dust constantly).


You may be asking: if my cells are dying anyways, why rejuvenate them or renew them? To make a very complicated process simple, MDPen is going to break down the difference. There are two types of cell death processes in our bodies:


  1. Apoptosis–these are the cells that are meant to die. Otherwise known as programmed cell death, these cells die because they are harmful, were injured, or it takes more energy to maintain them than to kill them.
  2. Senescence–these cells are static and result from constant exposure to stress and other toxins such as from the environment. These cells can build up, become toxic, and induce inflammation in the body, which can cause diseases such as autoimmune diseases and conditions such as arthritis. It is these cells that MDPen’s Cellular Renewal Serum target–both for preventing cell build up and for healing the damaged cells. Also, Cellular Renewal Serum targets healthy cells to keep them healthy.


In essence, Cellular Renewal Serum targets all cells to keep them healthy and enhance their appearance. Remember, the skin cells that die are in the outer layer of skin, the epidermis. Collagen and elastin are produced in the layer beneath that, the dermis. This layer does not die as quickly as the epidermis.




The name says it all here: cellular renewal serums aim to renew cells. MDPen’s Cellular Renewal Serum contains natural botanical extracts of knotgrass to enhance skin firmness and elasticity, while reducing the appearance of wrinkles and fine lines. The active ingredient of knotgrass visibly plumps out the skin and reduces lines and wrinkles in the process. This serum delivers powerful antioxidative moisture directly to deeper layers of the skin to give the skin a firmer, smoother texture, make pores smaller, and increase moisture levels. Our serum will combat free radicals, and reduce the appearance of damaged skin from the sun or age.


MDPen recommends Cellular Renewal Serum be used daily by patients who are being treated for acne, cellulite, stretch marks, scar revision, and uneven textures of the skin to rejuvenate the cells. Use this serum after a microneedling device session as well. One possible use is overnight treatment which penetrates deeply and gives the serum time to work its magic. Apply to freshly cleansed skin by massaging gently.


Skin cells are resilient; they stand up to pollution, harsh weather, and the effects of aging. MDPen’s Cellular Renewal serum uses knotgrass along with other ingredients to organically promote the normal functioning of the skin and serves as a catalyst for collagen and elastin production. Regular use of this serum will repair the structure of skin cells and increase skin’s radiance, smoothness, and suppleness. After a microneedling device, your skin will feel amazing as this Cellular Renewal Serum soothes the skin. Shop MD Pen online today!
