The Science Behind Using Derma Rollers for Effective Scar Healing
There have been a number of methods developed over the years for treating different types of scars. One of the newest and most promising is the use of derma rollers.
Covering us literally from head to toe, our skin—comprising the epidermis, basement membrane, and dermis—is the largest organ of the human body. As it is one of the few organs we (and others) can actually see with the naked eye, naturally we want it to look as youthful and attractive as possible. It’s kind of like an advertising billboard signaling our general healthiness to other people. Beauty may be only skin-deep, as they say; but as far as beauty goes, we’ll take what we can.
Among its many functions, skin also serves as our body’s first line of defense in the ongoing battle against microorganisms, ultraviolet rays, physical injury, and the myriad other “slings and arrows” of the outrageous external world. Unfortunately, over time (from the day we are born, actually) the visible outward effects of that battle accumulate on our skin in numerous ways: from old wound scars, to the acne scars of puberty, to postpartum stretch marks, to the wrinkles of old age. No one wants scars and wrinkles; but is there anything one can do about them? As it turns out, the answer is yes: with derma rolling.
To understand the science behind derma rolling and why it is proving so effective in treating various skin conditions, one must first understand a little how the skin works and, more particularly, the nature of scars.
