The practice of micro-needling basically creates numerous micro-punctures to the skin via a dermal-roller or dermal-pen apparatus creating thousands of micro-channels in the skin. The injury to the skin initiates activation and migration of fibroblasts to the site treated thus stimulating among other physiological responses, the deposition of collagen, triggering the wound cascade activating platelets, fibroblasts the the immune system and with the initial three recommended treatment, the resulting response can last for up to 1 year.
Micro-needling increases the availability of anti-oxidants and cell nutrients increasing cellular. It also increases the availability of skin lightening actives by enhancing absorption of topical treatments courtesy of the created micro-channels.
so what are the conditions micro-needling can address?
Lax skin and wrinkles – micro-needling triggers the wound cascade bringing platelets, epithelial, fibroblasts, endothelial together with the immune system together to ultimately produce more collagen to the treated areas and this, in addition to myofibroblast production produce a tightening, almost ‘contraction’ like effect resulting in reduction in wrinkle and lax skin appearence..
UV damage – depletes the anti-oxidants in the skin resulting in pigment deposition. Hyper-pigmentation can be caused by;UV damage, hormonal changes including pregnancy, other hormonal changes and post inflammatory trauma resulting from among, others, acne, insect bites, burns.
Acne – develops as a result of several factors including; excessive sebum production, hair follicle congestion, genetics, skin release of inflammatory mediators in the skin, the presence and activity of commensal bacteria cutibacterium acnes.
Micro-needling ‘normalises’ sebeocyte function and triggers the immune response that can control the bacteria and also he inflammatory cascade.
Roseacea – is a chronic and progressive skin disorder characterised by abnormal flushing appearance of the skin ultimately leading to chronic inflammatory changes and potential scarring. Typical aggrevators can include; UV exposure, over activity of the immune system, exercise, stress, extreme temperature changes, some chemical ingredients in skin care products, certain medications, hormones, digestive disorders, free radicals, food intolerance and Vitamin A deficiency.
Micro-needling stimulates Epidermal Growth Factor (EGF) which is a type of naturally occurring protein molecule found in skin fibroblast cells that contributes to cell growth which is essential to the healing and regeneration process. Micro-needling also increase platelet growth factor and increases the availability of cell nutrients and anti-oxidants.
Micro-needling can treat many (not all) conditions with minimal skin trauma but can occasionally be contra-indicated in a select few individuals which is why consultation is key to deliver safe treatment. Potential contra-indications include persons with ; active acne, taking anticoagulant medication, bleeding disorders, active herpes infection, those prone to keloid scarring.
Micro-needling practice should not therefore be considered a ‘mere cosmetic’ treatment as the benefits of the practice can potentially offer significant improvement to skin appearance and health that can present in the conditions discussed. Ultimately, these results may help to reduce the distress and anxiety caused to individuals who suffer with these conditions resulting hopefully in a reduced stressful and much improved quality of life.
