Microneedling, also known as Percutaneous Collagen Induction (PCI), is a non-surgical treatment offered at Liu Plastic Surgery for facial and skin rejuvenation. Microneedling can reduce the appearance of wrinkles, fine lines, acne scars, and other skin concerns.
Stimulate Collagen & Renew Your Skin with Microneedling
Our skilled San Jose plastic surgeons, Dr. Jerome Liu and Dr. Tom Liu, can customize and direct treatments, adjusting the needle depth based on your individual needs and delicate facial features. All treatments are performed by the aesthetic plastic surgery nurse practitioner, Michelle. The micro-perforations created by the microneedling device stimulate the body’s natural healing process and collagen production, leading to smoother, tighter, revitalized skin.

Benefits of Microneedling
While most patients choose to focus collagen induction treatment on facial rejuvenation, the treatment can be applied to any area of the body. Microneedling can also be used on all skin types and colors to treat a multitude of concerns, including acne scars and wrinkles. Furthermore, this procedure and technology can be used to treat stretch marks.
The unique design of microneedling devices allows for vertical micro-perforations during treatment, as opposed to the rolling technique often used in other needling treatments. This leads to more precise needling, less damage to the epidermis, improved patient comfort, and more rapid recovery

What to Expect
During treatment, the provider will carefully move the device over the desired treatment area, creating tiny punctures in the skin. The needle depth can be adjusted throughout treatment to accommodate various needs. Treatment typically takes less than an hour, but can vary depending on the desired treatment area. Temporary discomfort, similar to that of a mild sunburn, can occur afterwards. Recovery usually does not take long; most patients notice their skin has completely healed in as little as three days.
