Please fill out this form and we will contact you to schedule your consultation for a Microneedling or other aesthetic procedure.


At Knott Street, we now offer SkinPen treatments as it is the first microneedling device cleared by the U.S. Food and Drug Administration, clinically proven to safely and effectively treat facial acne scars.

Microneedling can also be used to treat fine lines and improve skin’s texture, tone and pigment. During this treatment, tiny needles are utilized to create micro-injuries or channels into the skin in order to produce collagen and elastin. The skin’s repair process results in a thicker dermis, improved fine lines and wrinkles, and overall skin texture. This treatment can be paired with PRP to further enhance results.
