Skin needling/ Microneedling
What is skin 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 non-ablative 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.
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.
- Hand rejuvenation
- Cellulite Reduction
Microneedle technology also offers a minimally invasive and painless route of trans-dermal drug administration e.g. vaccines. This technology, is currently being investigated by several research groups and companies. To enhance trans-dermal 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 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.
