The Science Behind Microneedling

Microneedling, also known as collagen induction therapy, is a minimally invasive skin rejuvenation procedure that has gained popularity for improving the appearance of scars, wrinkles, and stretch marks and enhancing skin texture and firmness. The science behind microneedling demonstrates its potential as an effective treatment to improve skin health and appearance by harnessing the body’s natural regenerative capabilities. The science behind microneedling revolves around the body’s natural wound-healing processes and involves several key biological mechanisms. Some of them are:

Creation of Micro-Injuries:

Microneedles devices are equipped with fine needles to create thousands of tiny, controlled punctures (micro-injuries) on the skin’s surface. These micro-injuries are superficial and typically only penetrate the uppermost layers of the skin (epidermis and superficial dermis).

Activation of the Healing Response:

The creation of micro-injuries triggers the body’s natural wound-healing processes. Three main phases characterize this response:

  • Inflammation: This initial phase involves recruiting immune cells to remove debris and bacteria from the injury site. This is crucial for preventing infection and setting the stage for the healing process.
  • Proliferation: During this phase, the body generates new granulation tissue, which is rich in collagen and elastin fibers, to replace the damaged skin tissue. Additionally, new blood vessels form to improve blood supply to the area, promoting the healing process.
  • Remodeling: In the final phase, the newly formed tissue is remodeled into stronger, more organized structures. The collagen produced in the earlier phase is now matured and cross-linked, resulting in firmer and more resilient skin.

Safety and Efficacy:

While microneedling is considered safe for most skin types, it is essential to have the procedure performed by a qualified and experienced professional to minimize risks and ensure optimal results. Post-treatment care is also crucial to support the healing process and protect the skin from sun exposure and other potential irritants.

At Universal Laser Center, we perform collagen induction therapy, the other name for the microneedling technique, using different devices. When we use a microneedle device, we combine it with other elements like cosmetic products and platelet-rich plasma or combine microneedling with other procedures like laser nonablative or near-infrared light, among others. We also have a treatment protocol for radiofrequency use with microneedles.

Benefits You Can Reap from Microneedling

One of the most significant outcomes when using microneedle devices is stimulating collagen and elastin production. Collagen and elastin are critical components of the skin’s structural matrix, providing firmness, elasticity, and strength. The increased production of these proteins helps to reduce the appearance of fine lines, wrinkles, and scars and improves overall skin texture and firmness.

Diminished fine lines and wrinkles are a common goal for many individuals seeking to maintain a youthful appearance. Various factors, including sun exposure, genetic predisposition, lifestyle choices, and natural aging processes, can cause these signs of aging. The skin becomes thinner, less elastic, and more fragile over time, primarily due to the breakdown of collagen and elastin—two key proteins that provide the skin’s structure and elasticity. As collagen and elastin decrease, the skin is less able to retain moisture, forming fine lines and wrinkles.

Enhanced skin texture and tone are desirable outcomes for anyone looking to improve their skin’s appearance, contributing to a more youthful, radiant, and healthy look. Skin texture refers to the skin’s surface condition, ideally smooth and soft, without significant bumps, rough patches, or scaly areas. Skin tone, on the other hand, concerns the skin’s evenness in color, free from discoloration, redness, or hyperpigmentation.

At Universal Laser Center, through the microneedle application skin care protocol, aestheticians create microchannels in the skin, and microneedling can enhance the absorption and efficacy of topical skin care products. The same technique is applied when platelet-rich plasma treatment is combined with PRP. 

Scar reduction through facial microneedling is an increasingly popular technique due to its effectiveness and minimally invasive nature. Microneedling helps reduce scars by promoting the skin’s natural healing processes, including collagen and elastin production, which are crucial for healthy, resilient skin.

How Microneedling Helps in Scar Reduction

  • Collagen Production: The procedure stimulates collagen production through the body’s wound-healing response to the micro-injuries caused by the needles. Increased collagen can help fill in and smooth out scars.
  • Improving Skin Texture: By promoting the regeneration of skin cells, microneedling can improve the texture and appearance of scarred skin, making scars less noticeable.
  • Breaking Down Scar Tissue: Regular microneedling sessions can break down old scar tissue and promote the synthesis of new, healthy skin tissue.

Types of Scars Addressed

  • Atrophic Scars are indentations left in the skin from acne or chickenpox. Microneedling can raise the depression, making the scars less pronounced.
  • Hypertrophic Scars: These raised scars can also benefit from microneedling, as it can help to flatten and smooth them over time.
  • Post-Surgical Scars: Scars from surgeries can be softened and less visible with microneedling.
