Why should I train in micro-needling as a medical professional?

Micro-needling, or collagen induction therapy, is a cosmetic procedure involving fine needles in a pen or roller device to create tiny punctures in the skin. These punctures stimulate the body's natural healing response, leading to several benefits.

Skin rejuvenation:

Micro-needling promotes the production of collagen and elastin, which are essential for maintaining the skin's strength, elasticity, and youthful appearance. The treatment can reduce fine lines, wrinkles, and acne scars, resulting in smoother, firmer, and more even-toned skin.

Improved texture and tone:

Micro-needling can help improve the overall texture and tone of the skin. It can minimise pore size, reduce hyperpigmentation, and even out rough or uneven skin.

Enhanced product absorption:

The micro-channels created during the procedure allow for better absorption of topical products, such as serums and creams. This can maximise the effectiveness of skincare products by delivering active ingredients deeper into the skin.

Minimal downtime:

Compared to more invasive procedures, micro-needling has minimal downtime and a relatively low risk of complications. It is a non-surgical and minimally invasive treatment that can be performed in an outpatient setting.


Micro-needling is suitable for various skin types and can be used to address a wide range of skin concerns, including signs of ageing, scarring, stretch marks, and uneven pigmentation. It can be performed on the face, neck, chest, and other body areas.

Patient satisfaction:

Micro-needling has gained popularity due to its effectiveness and high patient satisfaction rates. Providing this treatment can contribute to patient retention and attract new clients seeking skin rejuvenation solutions.

Complementary to other treatments:

Micro-needling can be combined with other cosmetic procedures, such as chemical peels or laser resurfacing, to enhance their outcomes. As a medical professional trained in micro-needling, you can offer comprehensive treatment plans and provide your patients with more options.

The scientific method of action of micro-needling

Mechanical stimulation:

Micro-needling utilises a device with fine needles, typically in the form of a roller or pen, which creates controlled micro-injuries in the skin. The needles penetrate the epidermis and reach the dermis, the deeper layer of the skin. This mechanical stimulation triggers a wound-healing response.

Inflammatory response:

The micro-injuries caused by the needles initiate an acute inflammatory response. This response involves the release of various chemical signals and growth factors, including platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-β), and fibroblast growth factor (FGF).

Collagen production:

The inflammatory response signals the activation of fibroblasts, which are cells responsible for producing collagen, elastin, and other components of the extracellular matrix. Collagen is a structural protein that provides support and strength to the skin. Increased collagen production helps in the repair and remodelling of the damaged skin tissue.


Micro-needling also promotes the formation of new blood vessels, a process known as neovascularisation. This increased blood supply brings oxygen, nutrients, and immune cells to the treated area, supporting tissue regeneration and rejuvenation.

Remodelling phase:

Over time, the newly formed collagen and elastin fibres organise and remodel the treated area, leading to improved skin texture, elasticity, and firmness. This remodelling phase continues for several weeks to months following the micro-needling procedure.

Benefits for a medical professional training in micro-needling

A holistic approach to skincare:

Micro-needling can be used in conjunction with other cosmetic treatments, such as chemical peels or laser therapies, to achieve synergistic effects. Training in micro needling allows you to develop comprehensive treatment plans, offering your patients a holistic approach to skincare and optimal results.

Professional growth and competitiveness:

Expanding your skill set by training in micro-needling can enhance your professional growth and make you more competitive in the field of aesthetic medicine. It demonstrates your commitment to staying up-to-date with the latest advancements and providing patients with state-of-the-art treatments.

Practice differentiation:

In an increasingly competitive market, offering micro-needling can help differentiate your practice from others. This can attract new patients seeking this treatment, leading to practice growth and increased revenue potential.

Safety and patient care:

Proper training in micro needling ensures that you possess the necessary knowledge and skills to perform the procedure safely and effectively. This includes understanding contraindications, managing potential complications, and providing optimal patient care throughout the treatment process.

Let's explore some examples of the applications of micro-needling in various treatments

Anti-Ageing and Wrinkle Reduction:

Micro-needling is commonly used for its anti-ageing effects. Stimulating collagen production and remodelling can help reduce the appearance of fine lines and wrinkles. Additionally, micro-needling can improve skin laxity and firmness, giving a more youthful appearance. Regular sessions of micro-needling can lead to significant improvements in skin texture and overall rejuvenation.

Scar Revision:

Micro-needling has shown promising results in the treatment of different types of scars, including acne scars, surgical scars, and stretch marks. The procedure helps break down scar tissue and stimulates the production of new collagen, leading to a smoother and more even skin texture. With continued treatments, the appearance of scars can be minimised and their visibility reduced.

Hyperpigmentation and Uneven Skin Tone:

Micro-needling can be effective in addressing hyperpigmentation and uneven skin tone caused by factors such as sun damage, melasma, or post-inflammatory hyperpigmentation. By promoting skin cell turnover and stimulating collagen production, micro-needling can help fade pigmentation irregularities and achieve a more even complexion.

Skin Rejuvenation and Radiance:

Micro-needling is often sought after for overall skin rejuvenation and to improve the skin's radiance. The procedure enhances the skin's texture, tone, and vitality by promoting collagen synthesis and improving blood circulation. It can also help reduce the appearance of pores, making the skin appear smoother and more refined.

Hair Loss Treatment:

Micro-needling has gained attention as a potential treatment for hair loss, particularly in cases of androgenetic alopecia (pattern hair loss). By creating micro-injuries in the scalp, micro-needling can stimulate the hair follicles, increase blood flow, and enhance the absorption of topical hair growth products. This approach may help promote hair regrowth and improve the thickness and quality of existing hair.

Skincare Product Absorption:

Micro-needling creates micro-channels in the skin, temporarily increasing its permeability. This enhanced permeability allows for better absorption of topical skincare products, including serums, creams, and growth factors. When applied immediately after a micro-needling treatment, these products can penetrate deeper into the skin, maximising their effectiveness and delivering nourishing ingredients directly to the targeted areas.

Combination with Other Treatments:

Micro-needling can be combined with other cosmetic procedures to enhance their outcomes. For example, it can be performed prior to applying topical anaesthetics to improve their absorption and efficacy during more invasive procedures. Micro-needling can also be used in conjunction with chemical peels or laser resurfacing to optimise the results and accelerate the healing process.

Micro-needling, or collagen induction therapy, stimulates the skin's natural healing response through mechanical stimulation and controlled micro-injuries. This leads to increased collagen production, neovascularisation, and tissue remodelling. The procedure offers numerous benefits, including anti-ageing effects, scar revision, hyperpigmentation treatment, skin rejuvenation, hair loss treatment, and improved product absorption. As a medical professional, training in micro-needling can provide you with a versatile treatment option, expand your practice offerings, and contribute to positive patient outcomes and satisfaction.

It is important to note that training in micro needling should be comprehensive, including theoretical knowledge, practical experience, and adherence to proper sterilisation and hygiene protocols. This ensures that you can deliver the treatment with the highest safety and quality standards.
