Microneedling : The Basics

Microneedling, also referred to as collagen induction therapy, can have really impressive results to improve acne scars, tissue paper like wrinkling of the skin, and persistent fine lines.
Essentially, multiple pin pricks are introduced to the skin to trigger collagen production below the surface. Small ‘microchannels’ are introduced into the skin to allow for the delivery of skin care products as well such as Hyaluronic acid and alpha hydroxy acids and platelet rich peptide (PRP also known as the vampire facial). 
The key to real results is how deep the needles penetrate the skin to really stimulate collagen. Collagen producing cells are in the dermis- this is the layer of the skin that is vascular. When we do microneedling in the office we use needles that actually go 1.5 to 2.5 or 3 mm deep. We use a power device to really get the same depth each time we puncture the skin. In spite of topical numbing, it can be very uncomfortable! It’s also a little messy during the procedure but shockingly little down time. The results are amazing. 
Microneedling outside of dermatologists office may only puncture the skin maybe 0.5 mm deep. This simply isn’t deep enough to get impressive results. I have seen ads for places that show before and after photos from medical studies that use needles that penetrate 2-3 mm deep to draw in customers however those spas only use shallow needles. Technically if there is no bleeding then your treatment may not have good results.
Dermarollers are an attempt to bring microneedling home but also used in spas. Again, these use shallow needles. The only other issue is the ‘drag’ of the needle rolling on the skin which can tear the skin easily- especially older skin.
