The Science Behind Micro Needling
The theory behind microneedling is that by making these tiny holes spaced apart in a given area of your skin (aka creating a controlled skin injury), your body will respond by sending collagen and elastin to heal the whole area.
In other words the collagen and elastin will not only heal the damaged area but also the areas around it, eventually smoothing out minor scars, flattening out fine lines and wrinkles, as well as promoting elasticity in the skin.
Additionally, if a product is introduced to the skin during micro needling, that product will be more effective since it penetrates deeper layers of the skin.
