WHY CHOOSE AESTHETICS BY DR RACHEL?
Effective microneedling depends on understanding skin anatomy, adjusting depth appropriately, maintaining high standards of hygiene, and selecting the right treatment approach for your skin. Doctor-led microneedling offers an added level of clinical oversight, safety, and personalised care giving you optimal results.
Microneedling creates controlled micro-injuries that trigger the body’s wound-healing cascade. This process stimulates collagen and elastin production within the dermis, with studies showing increases in collagen levels of up to 400% over time. Rather than relying on surface treatments, microneedling harnesses the skin’s own repair mechanisms to support true dermal regeneration. This is collagen induction therapy working at a cellular level, using the skin’s own repair mechanisms to improve strength, texture, and quality.
What sets medical microneedling apart is the combination of advanced, medical-grade serums and the ability to work at greater depths than standard microneedling. As a doctor, I am able to tailor needle depth precisely according to the area being treated, skin thickness, and the concern being addressed, allowing powerful treatment serums to reach the layers where real change occurs. These serums are delivered through the micro-channels created during microneedling, allowing deeper penetration than topical application alone and supporting meaningful, long-term improvement in skin quality.
Medical microneedling is suitable for all skin types, including darker skin tones where some energy-based treatments can carry a higher risk of pigmentation changes. As a non-ablative treatment, it works without removing or destroying tissue, meaning recovery is typically straightforward. Medical microneedling can be used to improve a wide range of concerns, including acne scarring, stretch marks, fine lines, pigmentation, enlarged pores, and even scalp hair thinning. This versatility allows microneedling to be safely adapted to different areas and skin types, making it a valuable option where other treatments may be less appropriate.
Doctor-led microneedling allows for precise needle depth calibration, typically ranging from 0.5 mm to 2.5 mm depending on the area treated and the concern being addressed. Treatment is performed using sterile technique, with careful selection of medical-grade serums and the ability to recognise and manage complications should they arise. This level of clinical oversight allows microneedling to be used as a form of true dermal repair, rather than a superficial skin treatment. Depth, technique, and product choice are all tailored to the individual, ensuring treatments are both safe and effective. It is this medical expertise and attention to detail that elevates outcomes and supports consistent, high-quality results over time.
Medical microneedling is collagen induction therapy designed to stimulate the skin’s natural wound-healing processes, supporting collagen production and tissue regeneration at a deeper level.
"Microneedling works by harnessing the body’s natural and highly effective wound-healing biology. When performed in a controlled, medical setting, it encourages the skin to repair, strengthen, and regenerate itself from within.
When tiny needles create precise micro-injuries within the dermis, the skin recognises this as a signal to begin repair. This process unfolds in three carefully coordinated phases.
Phase 1: Early Healing Response (first few hours)
The skin releases growth factors and signalling molecules that initiate repair. Blood platelets are drawn to the treated areas, helping to start the regeneration process. This response is controlled and purposeful, supporting healing rather than causing damage.
Phase 2: Repair and Renewal (days to weeks)
Fibroblast cells migrate to the treated areas and begin producing new collagen and elastin. New micro-circulation develops, improving oxygen and nutrient delivery to the skin. During this phase, skin strength, texture, and quality begin to improve.
Phase 3: Remodelling and Maturation (weeks 4–12)
Newly formed collagen continues to mature and organise into a stronger, more functional dermal structure. Over time, the skin becomes firmer, smoother, and more resilient, with results continuing to develop for up to twelve weeks.
One of the key advantages of medical microneedling is precision. I carefully tailor needle depth to the area being treated and the concern being addressed.
Superficial depths are used to enhance radiance and product penetration, medium depths to improve fine lines and texture, and deeper treatments for scarring and more significant structural remodelling. This individualised approach allows results to be optimised while maintaining safety.
What further differentiates medical microneedling is the use of advanced, medical-grade serums during treatment. The micro-channels created allow active ingredients to penetrate far more effectively than they would through intact skin.
I offer three carefully selected serum options:
NCTF 135 HA: A poly-revitalising formulation containing over 50 active ingredients, including hyaluronic acid, amino acids, vitamins, minerals, and antioxidants. This supports hydration, luminosity, and long-term skin quality.
Topical PDRNs (Polynucleotides): A high-strength polynucleotide formulation that combines PDRNs (building blocks of DNA), with skin-nourishing hyaluronic acid and niacinamide. This combination supports cellular repair, hydration at multiple skin levels, and barrier function, helping to enhance tissue regeneration and collagen quality, tackling multiple signs of ageing in the skin.
Exosomes: Next-generation technology designed to support skin repair and regeneration at a cellular level. They contain purified extracellular vesicles rich in signalling molecules that help improve communication between skin cells, encouraging repair, renewal, and collagen stimulation over time. Exosomes are particularly effective for improving scarring and treating stubborn pigmentation.
During your treatment, precise microneedling is performed across the treatment areas using your chosen serum. Most patients describe the sensation as firm pressure with manageable discomfort, and the procedure is generally very well tolerated.
After treatment, the skin typically appears flushed and warm, similar to the glow you might see after brisk exercise. This usually settles within 24 hours. Many patients notice an immediate improvement in brightness and skin vitality, with deeper, longer-term improvements continuing to develop over the following weeks as new collagen forms and matures."

"I had medical microneedling with exosomes for my acne scarring, and the results are phenomenal. My skin texture has dramatically improved, and the deep scars have softened significantly. Dr Rachel explained everything so clearly and made me feel completely comfortable. This treatment has genuinely changed my confidence."

Microneedling
"Microneedling may appear straightforward, but achieving safe, consistent, and meaningful results relies on medical expertise and clinical judgement.
As a GMC-registered GP, I bring a detailed understanding of skin anatomy, facial structure, and individual variation. I understand how dermal depth differs across facial zones, where important vascular structures lie beneath the skin, and how to calibrate needle depth precisely to stimulate collagen while protecting tissue integrity.
Equally important is accurate diagnosis. Not every skin concern is best treated with microneedling alone. Some patterns of scarring respond better to alternative resurfacing approaches, some skin concerns benefit from injectable regenerative treatments, and others require targeted chemical resurfacing for pigmentation. Identifying the most appropriate treatment pathway requires medical training and experience.
Serum selection also plays a critical role. Different formulations support different biological processes: some enhance hydration and radiance, others support tissue repair and recovery, while more advanced regenerative options help encourage collagen renewal in more challenging cases. Matching the right serum to your skin biology is key to achieving optimal outcomes.
Safety underpins every treatment I perform. Microneedling temporarily creates micro-channels within the skin, which requires strict sterile technique and medical-grade infection control. I use single-use sterile needle cartridges and adhere to clinical hygiene standards designed to minimise risk and support safe healing.
Aftercare and follow-up are equally important. I provide clear post-treatment guidance, including gentle skincare, sun protection, and recovery support, and I monitor progress so treatment plans can be adjusted if sensitivity or unexpected reactions occur.
As a member of CMAC (the Complications in Medical Aesthetic Collaborative), I remain up to date with best-practice safety protocols and have the training and support to recognise and manage complications promptly, should they arise.
When compared with energy-based resurfacing treatments, microneedling offers a non-ablative approach to collagen induction that works without heat-related tissue damage. This makes it a versatile option across a wide range of skin types, including those where pigmentation risk must be carefully considered.
Doctor-led microneedling within a GP-run clinic prioritises precision, safety, and long-term skin health - ensuring treatments are tailored, evidence-based, and delivered with clinical oversight at every stage."
