The Science Behind Microneedling: How It Works and Its Benefits

Share Post

In the realm of skincare, microneedling has emerged as a revolutionary treatment for those seeking to rejuvenate their skin. This minimally invasive procedure promises to improve skin texture, reduce the appearance of scars, and promote a youthful complexion. But what exactly is microneedling, and how does it work? In this blog, we’ll delve into the science behind microneedling and explore its numerous benefits.

What Is Microneedling?

Microneedling, also known as collagen induction therapy, involves using fine needles to create tiny, controlled punctures in the skin’s surface. These micro-injuries trigger the body’s natural healing process, stimulating the production of collagen and elastin—two proteins essential for maintaining firm, smooth, and youthful skin.

How Does Microneedling Work?

The process of microneedling can be broken down into several key stages:

  1. Preparation: Before the procedure, your skin is thoroughly cleansed, and a topical anaesthetic is applied to ensure comfort during the treatment.
  2. Microneedling Procedure: A device with fine needles, either a dermaroller or a dermapen, is gently moved across the treatment area. The needles create micro-injuries, which are tiny punctures in the skin.
  3. Healing Response: The body responds to these micro-injuries by initiating the healing process. This involves the production of new collagen and elastin, which helps to repair and rejuvenate the skin.
  4. Recovery: After the procedure, the skin may appear slightly red and feel sensitive, similar to a mild sunburn. This typically subsides within a few days, and post-treatment care, including the use of soothing products and sun protection, is essential.

The Benefits of Microneedling

  1. Improved Skin Texture and Tone: Microneedling helps to smooth out rough patches, reduce the appearance of pores, and create a more even complexion. The increased collagen production results in firmer, more resilient skin.
  2. Reduction of Fine Lines and Wrinkles: By stimulating collagen and elastin production, microneedling can help to reduce the appearance of fine lines and wrinkles. This makes it an effective anti-ageing treatment, promoting a more youthful appearance.
  3. Minimisation of Scars: Microneedling is particularly effective for reducing the appearance of acne scars and other types of scarring. The treatment promotes the regeneration of skin cells and the breakdown of old scar tissue.
  4. Enhanced Absorption of Skincare Products: The micro-channels created during microneedling allow for better absorption of skincare products. This means that serums and other treatments applied post-procedure can penetrate deeper into the skin, enhancing their effectiveness.
  5. Safe for All Skin Types: Microneedling is a versatile treatment that is suitable for all skin types and tones. It offers a low risk of hyperpigmentation, making it a safe option for those with darker skin.

What to Expect During and After Microneedling

  1. During the Procedure: The microneedling procedure typically takes about 30 to 60 minutes, depending on the size of the treatment area. The sensation is often described as a mild tingling or prickling, but the topical anaesthetic ensures minimal discomfort.
  2. Post-Treatment Care: After microneedling, it’s important to follow your practitioner’s aftercare instructions. This usually includes avoiding sun exposure, refraining from using harsh skincare products, and keeping the skin hydrated and protected.
  3. Results: You may notice an immediate glow to your skin after the treatment, but the full benefits of microneedling develop gradually as new collagen is produced. Optimal results are typically seen after a series of treatments spaced several weeks apart.


Microneedling is a scientifically-backed, effective treatment for those looking to rejuvenate their skin and address various skin concerns. By stimulating the body’s natural healing processes, microneedling can improve skin texture, reduce the appearance of fine lines and scars, and promote a youthful, radiant complexion.
