Microneedling, or micro-needle induction therapy, is a remarkable advance in aesthetic medicine. This non-invasive method stimulates collagen and elastin production, offering an effective solution to various skin problems. This article explains how microneedling works, what it is used to treat, its benefits for your skin, and post-treatment care.
Definition of microneedling
Microneedling uses a device equipped with small needles to create fine perforations in the surface or middle layer of the skin, depending on the desired results. This technique activates the skin’s natural self-healing mechanism, resulting in improved firmness, youthfulness and texture, with a reduction in problems such as acne and pigmentation spots.
Why do microneedling?
For its anti-ageing action by stimulating the production of collagen and elastin fibres, this technique uses mechanical stimulation with needles to effectively reduce fine lines and wrinkles and prevent and actively combat sagging skin.
For its improvement of skin quality and texture by reducing acne scars, tightening enlarged pores and diminishing the appearance of skin problems such as sagging skin and stretch marks.
For its skin tone evening properties by improving radiance and complexion and reducing brown spots caused by hyperpigmentation.
How does a microneedling session work?
1. A mandatory prior consultation with a doctor
- Before the first microneedling session, this step allows the doctor to assess the condition of the skin, discuss expectations and establish a personalised treatment plan. This consultation also includes checking for contraindications and preparing a quote.
2. Preparing the skin
The session begins with thorough make-up removal and cleansing of the face or body area to be treated.
3. Local anaesthesia
- An anaesthetic cream is applied and left on for approximately 30 minutes to ensure optimal comfort during the treatment.
4. Treatment
The microneedling treatment is then carried out, with the duration varying depending on the size of the area concerned. Several passes are made during the same session, depending on the skin problems.
The depth of the microneedles in the dermis is adjusted according to each area of the face or body. This depth depends on the thickness of the skin, which varies.
For example, on the face, the depth is different on the forehead, cheeks, eye contour, etc. A skin booster such as NCTF, containing hyaluronic acid, vitamins, amino acids, peptides, minerals, etc., can also be applied to the entire face and neck at the end or beginning of the treatment. This combination of treatment techniques provides a complete anti-ageing treatment.
5. In post-processing
- A skin booster enriched with active ingredients such as hyaluronic acid, vitamins and amino acids, such as NCTF, is applied to maximise the benefits to skin quality and minimise inflammation.
Precautions to take after a microneedling session:
It is essential to follow your doctor’s recommendations after treatment to promote optimal healing. Common advice includes using moisturisers, avoiding direct exposure to the sun, and applying sunscreen regularly every day. No swimming pools, steam rooms or saunas. Avoid baths, but showers are fine.
Ideal candidates for microneedling
This technique is suitable for all skin types, women and men, all skin tones, and is particularly recommended for those seeking to improve the appearance of their skin on the face, neck, décolleté and body without invasive procedures.
Microneedling offers a safe and effective method using micro-needles to revitalise the skin by activating natural skin repair processes, ensuring visible and long-lasting results.
How does microneedling work?
What is collagen?
It is a vital protein that serves as the main component of connective tissue in our bodies, including the skin. It is responsible for the skin’s firmness, elasticity and regeneration. With age, its natural production decreases, leading to the appearance of signs of ageing such as wrinkles, loss of firmness and other skin changes.
The Principle of Microneedling:
Microneedling uses a special device equipped with micro-needles to create tiny perforations. Although these perforations are superficial, they are significant enough to activate the body’s natural healing mechanisms without causing permanent damage to the skin.
To induce the healing response:
When the microneedles penetrate the skin, they cause micro-lesions in the epidermal layers, triggering a natural inflammatory response. This response initiates the healing process, which includes the production of new collagen fibres.
To stimulate growth factors:
The creation of micro-lesions also increases the production of growth factors. These growth factors are essential for the formation of new collagen and elastin, thereby helping to strengthen and rejuvenate the skin’s structure.
To remodel collagen in the dermis:
Over the course of several sessions, microneedling helps to organise and densify this protein, improving the texture and elasticity of the skin.
Influence of Needle Depth
The depth of the needles in a microneedling treatment can vary from 0.25 mm to 2.5 mm, directly influencing the effectiveness and type of skin response:
0.25 to 0.5 mm
- Skin surface: Ideal for improving the absorption of topical products.
- Objectives: Hydration, radiance for the skin of the face and neck.
0.5 to 1.0 mm
1.0 to 2.0 mm
- Deep dermis: Suitable for treating deeper acne scars and fine lines and wrinkles.
- Objectives: Deep regeneration, significant reduction in signs of ageing and scars.
2.0 to 2.5 mm
- Deep dermis to subcutaneous layer: Generally reserved for medical treatments performed by experienced professionals.
- Objectives: Treatment of severe scars, stretch marks and significant loss of firmness.
When can I expect results?
The effects of microneedling become apparent gradually, day after day, as collagen and elastin production does not occur instantly. After the first session, patients may notice brighter, smoother skin. Results in skin quality continue to improve with each session, typically between three and six, spaced a few weeks apart, depending on individual needs and skin type.
Possible combinations with other treatments
Microneedling can be combined with other cosmetic procedures to intensify results. For example, combining it with treatments such as chemical peels can accelerate skin surface renewal, while adding LED treatments can improve healing and reduce inflammation.
Each combination is carefully selected and customised to meet the patient’s specific goals while ensuring the safety and effectiveness of the treatment.
Tips for optimal post-microneedling care
After microneedling treatment, it is crucial to protect the skin from the sun and avoid any irritating products.
It is recommended to follow a gentle skincare regimen that includes non-abrasive cleansers, enriched moisturisers, and adequate sun protection to support healing and maximise results.
Patients are also encouraged to drink plenty of water and eat a diet rich in antioxidants to promote skin repair and protection from within.
In conclusion
Microneedling is an advanced technique that offers a multitude of benefits for the skin, ranging from reducing signs of ageing (fine lines, wrinkles and sagging) to improving texture and complexion. Thanks to its minimal yet effective approach, this method is suitable for a wide range of skin types and conditions, and can be tailored to meet the specific needs of each individual. To determine if microneedling is the right option for you, consult a qualified aesthetic medicine professional who can assess your skin and discuss the best treatment strategies for your aesthetic goals.
With its impressive results and short recovery time, microneedling continues to grow in popularity and has become a mainstay of modern beauty treatments, allowing everyone to feel more confident and satisfied with their appearance.
