What is micro needling and how does it work?
Skin needling is also called micro-needling therapy or collagen induction therapy. It is a minimally-invasive non-surgical and nonablative procedure for facial rejuvenation that involves the use of a micro-needling device to create controlled skin injury.
As each fine needle punctures the skin, it creates a channel or micro-wound. The controlled injury triggers the body to fill these micro-wounds by producing new collagen and elastin in the papillary dermis. In addition, new capillaries are formed. This neovascularisation and neocollagenesis following treatment leads to reduction of scars and skin rejuvenation, i.e., improved skin texture, firmness and hydration.
Professional skin needling is considered to be one of the safest skin treatment procedures. Unlike chemical peels, dermabrasion and laser treatments, skin needling causes minimal damage to the skin.
What is skin needling used for?
Skin needling is effectively used for:
- Reducing scars (including hypertrophic scars) caused by acne, surgery or thermal burns
- Fading stretch marks
- Reducing fine lines and deep wrinkles
- Dyspigmentation e.g in melasma
- Tightening sagging skin
Microneedle technology also offers a minimally invasive and painless route of transdermal drug administration e.g. vaccines. This technology, is currently being investigated by several research groups and companies. To enhance transdermal drug transport, microneedles can be inserted into the skin to increase its permeability, after which the drug is applied (poke with patch). Drugs could also be coated onto the microneedles and then inserted into the skin (coat and poke). Hollow microneedles are used to inject drug solutions into the skin.
Benefits of skin needling:
Reduced risk of hyperpigmentation and scarring therefore safe on ethnic or dark skin.
- Suitable for thin and sensitive skin.
- The treatment can be performed in an office setting and does not need any extensive special training or expensive instruments.
- The procedure is well tolerated and well accepted by the patients.
- It is cost-effective, and can be done on areas of skin not suitable for peeling or laser resurfacing, such as near eyes.
- As opposed to ablative laser resurfacing, the epidermis remains intact and is not damaged. For this reason, the operation can be safely repeated if needed.
- Treatment does not result in a line of demarcation between treated and untreated skin, as usually occurs with other resurfacing procedures. This allows for specific areas of scarring to be treated without the need to “blend” or “feather” at the treatment edges.
- The patient can resume regular activities within a few days, depending on the depth of penetration of the needles. Treatment options like laser resurfacing or dermabrasion are often associated with considerable morbidity and downtime from daily activities of the patient in the post-treatment period.
Is Medical Micro-Needling painful?
Prior to the treatment, numbing cream can be applied to minimize pain that is felt during the procedure.
How many skin needling procedures does one need?
The number of needling procedures depends on the individual skin condition. Three to four treatments may be needed for moderate acne scars. Scars from Thermal burns and stretch marks (striae) may require up to 5 procedures.
In the case of wrinkles associated with ageing skin, one or two refresher skin needling treatments are recommended every year.
Specially designed home skin needling models with short fine needles (0.2 mm depth) may be used 2-3 times per week to:
reduce pore size
- reduce oil levels in the skin (seborrhoea)
- help to reduce wrinkles and fine lines
- enhance delivery and effectiveness of medical grade skincare creams
- minimize acne outbreaks.
