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 penetrate 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.
There are no major contraindications for Collagen Induction Therapy. As with all cosmetic treatments, the ideal candidate should have realistic expectations and be in generally good health. The treatment is suitable for all skin types, unlike some laser or chemical peels procedures. If you have any of the following concerns, you may be a suitable candidate for Collagen Induction Therapy: • Premature ageing
• Skin Laxity
• Lines and wrinkles
• Scarring from acne, chicken pox, injuries or surgery
After Collagen Induction Therapy Treatment, your skin will be a bit red or pink. You may also get some bleeding and bruising, however this should be minimal and will depend on the length of the needle used during your treatment. The downtime with this treatment is very quick and you should have recovered between 24-72 hours.
Because the results of this treatment rely on kick-starting your body’s own collagen production, it can take between four to eight weeks before you start to fully see the benefits. A series of between three and five treatments is usually recommended to achieve maximum results.
