What is Microneedling and What Is it Used For?

Microneedling , also known as collagen induction therapy, is a multifunctional, noninvasive, cosmetic procedure that utilizes numerous tiny “micro” needles, for precise and controlled puncturing of the skin to regenerate and rejuvenate the skin. Microneedling enhances the overall appearance of the skin, and can help with fine lines, texture, and discoloration. Its global rejuvenation effects are similar to a milder form of Fraxel, or fractional nonablative laser resurfacing. When specific settings are applied with the correct equipment, it can even be used to treat surgical or traumatic scars, or depressed acne scars, similar to a fractional nonablative laser. The intensity of each microneedling session can easily be controlled by altering the device settings and hardware.

How does Microneedling Work?

Precisely patterned micro punctures of the skin created by sterile, high powered microneedles induce the skin to produce more collagen in an attempt to fill in the controlled micropuncture wounds. When applied over a localized or generalized surface area, the entire treated area is stimulated to regenerate itself, creating skin that has smoother texture, more even coloration, and increased thickness.

How is Medical Microneedling different from Home Devices?

Medical Grade Microneedling is performed using sterile equipment that is much more powerful and effective than at-home devices. When performed by a dermatologist, the appropriate numbing medication is applied prior to treatment, proper sterile techniques are utilized to reduce infection, appropriate postoperative instructions are given, and the procedure is performed with a level of expertise that is beyond that of routine consumers. This results better outcomes (with less adverse events) when compared to the pretreatment baseline.

What is the Recovery Time with Microneedling?

Recovery time can range from 3-6 days depending on how aggressive the treatment is. This in turn, depends on the cosmetic concern that is being addressed. The face is usually pink and swollen in the first 2 days, and this effect fades over the next several days. Sun exposure is strictly prohibited for 2 weeks. Specific skin care instructions are given to patients after the microneedling session.

How many Treatments of Microneedling do I need?

Treatment number depends on cosmetic goals. In general, multiple microneedling sessions are needed for optimal outcomes. Scar treatments for example, require an average of 6 treatments for satisfactory improvement.

Is Microneedling Painful?

No, when the skin is appropriately numbed, the microneedling procedure should be a pain-free experience. There may be mild discomfort in the first few days after the procedure, akin to a mild sunburn.

Am I a Candidate for Microneedling?

Set up a consultation with Dr. Tzu to discuss whether microneedling is the right procedure for your specific concern. Certain medical conditions may preclude the ability to safely perform microneedling on the skin, so it is important that you inform your physician of all of your medical conditions. Microneedling is only one of many cosmetic treatments that can be performed to enhance the appearance of the skin. During your consultation, Dr. Tzu may discuss other procedural options should microneedling not be the most suitable procedure for your cosmetic goals.
