What is Dermarolling?/Facial Collagen Induction Therapy
Dermarolling (CIT) remolds the skin by creating thousands of microscopic channels through the skin, increasing the formation of new tissue by activating the body’s wound healing cascade (hemostasis-inflammation-proliferation-tissue remodeling). The micro-channeling causes the release of growth factors that promote scar-less healing and the deposition of normal woven collagen rather than scar collagen. The fibroblasts are responsible for collagen production. The exact mechanism how this happens is complex and not yet completely understood. New collagen and elastin forms. In one study, twenty blinded biopsies taken from 10 different patients from various parts of their body demonstrated an average increase in new fibers of 206%, in one biopsy a 1000% increase was recorded
There are not alot of ways to rejuvenate the skin. Perhaps the best method is to cause mild skin injury. The body will immediately start repairing that injury by replacing the injured skin with new skin. That is the main principle of microneedling (“dermarolling”)(CIT). Injuring the skin forces the body to renew it. The injury has to be just serious enough to trigger the healing processes, but not serious enough to permanently damage the skin. Microneedling is the ideal mechanism for that.The same principle is behind most laser rejuvenation treatments, acid peels and other invasive skin rejuvenating methods. The laser either evaporates the top layer(s) of the skin entirely or it evaporates only fractions of the skin (“Fraxel laser”)A dermaroller creates microinjuries (tiny vertical channels in the dermis) mechanically, while fractional laser treatment makes them thermically. But the principle is the same. The resulting collagen production will slowly  progress even months after the treatment.When you sting yourself with a needle, you mechanically damage some skin cells. Those cells are too damaged to function properly and our body will immediately start removing those cells. These cells are then being replaced by new cells.So based on this principle, dermarolling speeds up the turnover of the skin and thus speeds up the diminishing of pigmentations, post-acne spots, age spots etc.     
How dermarolling and needling in general works on stretch marks and scars:Scar tissue, whether raised, flat or indented is usually abundant in collagen but the scar collagen is thick and typically woven in a different pattern than in the normal skin.Scar tissue isn’t really too different from normal skin, it’s only the thickness and patterns of the fibers that differ.Crushing the scar tissue will crush the scar pattern of the fibers and the body will often remodel the scar into a smoother, better looking, softer scar.     Our body does not expend effort on fixing things it does not consider “broken”. Scar tissue is just a cosmetic problem, it is not perceived as an issue worthy of fixing further by the body. Dermaneedling is a strategy to force the body to remodel the scar. The trick is that making tiny pricks is not sufficient damage to cause a scar but it is enough for the body to consider needled skin as “broken”. Dermaneedling triggers healing processes. Unfortunately, our body usually does not bother replacing the scar tissue completely with normal skin – especially when the scar is deep – but it often replaces it with a mixture of scar- and normal tissue, producing a better looking scar.So dermarolling triggers healing processes and the body tends to heal the area in a way – at least partially – as normal skin should look like. Indented scars fill in and raised scars flatten. It does not work in all cases, but in most people it does work.     Acne scars don’t contain much scar tissue but they are atrophied (missing tissue). The scar will slowly or partially fill in with collagen triggered by a dermaroller, dermastamp or single needle. Wrinkles will also partially fill in.In addition, needling a hypopigmented scar will facilitate the migration of melanocytes (skin-pigment producing cells)  from the surrounding skin into the scar and improve its color.     Dermarolling does not remove any skin layers. It only makes pricks into the skin. That is why the skin heals rapidly from dermarolling comparing to methods that remove skin layers. Dermarolling is for that reason also much less prone to infection or healing complication and it has a very short downtime.
Dermarollers can be used for fine line and wrinkles, acne scars, facial cosmetic scars, body scars, keloid scars, stretch marks and hyperpigmentation.You will see a difference in just a few treatments.Depending on the depth of the treatment will depend on the time between the next appointment. I usually make appointments for 3-4 weeks between dermarolling procedures.Down time is minimal as you are red for about 24 hours with some possible blood spots under the skin. No makeup or moisturizes are recommended until 48 hours after dermarolling procedure. You will come to your appointment with a clean face, we will use a topical lidocaine to numb the area being treated. This is a great procedure to help the skin and with little down time its perfect for the person on the go!
