Collagen Induction Therapy (CIT)—also known as micro-needling—is a procedure that improves the appearance of wrinkles, acne scars and stretch marks by stimulating your skin’s natural ability to repair itself. Collagen Induction Therapy uses tiny, sharp needles to create hundreds of micro-channels in the superficial layers of the skin. In response to these micro-injuries, your body releases growth factors and cytokines, which trigger the wound-healing process. During this process, the body produces more collagen—a fibrous protein that contributes to the structural integrity of the skin—resulting in thicker more youthful-appearing skin.
The micro-channels allow topical skincare products to pe*****te your skin more deeply, so the products work better. CIT doesn’t damage the epidermis, and it can be repeated safely. CIT can also be used on regions that may not be suitable for laser resurfacing or peels such as eyes, mouth, hands and chest.
There are three phases to the process:
Phase I: Inflammation. Piercing the skin triggers your immune system to disinfect the wounds, remove debris, increase blood flow and begin to create new tissue.
Phase II: Proliferation. The wound is re-built with new granulation cells, as well as a temporary (type III) collagen and elastin, which are part of the extracellular matrix. Additionally, a new network of blood vessels develops.
Phase III: Remodeling. The wound has been replaced with new dermal tissues and blood vessels. The type III collagen in the newly formed tissue is replaced with stronger type I collagen, which can contract to create a tightening or "shrink wrap" effect on the skin.
How Is Micro-Needling Performed?
Micro-needling can be performed using SkinPen—a medical-grade, state-of-the-art micro-needling tool available only through medical professionals. SkinPen is used to treat small facial areas or large body surfaces. The treatment typically takes about 30 minutes, depending on the size and number of areas treated and the degree of treatment requested by the patient.
The SkinPen needle depth adjusts from .25 mm up to 2 mm, allowing the provider to tailor the treatments to the patient’s particular anatomy (skin thickness) as well as his or her needs. SkinPen’s variable needle depth makes it more versatile than traditional rollers, and it can be used efficiently on many parts of the body, including face, neck, décolletage, arms, hands, legs, abdomen and back. This makes it particularly useful for aiding in the reduction of fine lines, wrinkles, scars (acne, trauma, surgical) and stretch marks.
Does It Hurt?
A topical anesthetic is typically applied prior to a SkinPen treatment. This allows for a comfortable experience for the patient.
Is There Downtime?
The patient will typically leave the office with mild to moderate redness and slight swelling in the treated area. This usually resolves by the following morning.
