What is microneedling?

Microneedling involves the use of tiny sterile needles to create micropunctures in the skin to stimulate the wound healing process in the dermis without causing significant damage to the epidermis. The wound healing process causes an increase in the amount of growth factors in the skin. These growth factors act to increase the production of collagen and elastin in the dermis.

Microneedling is becoming an increasingly popular method of skin rejuvenation to reduce fine lines and wrinkles and also in the treatment of scarring. Click here to read more about acne scar treatments.

Does microneedling hurt?

The nature of microneedles means that the process of microneedling is relatively pain-free. The process is often described by clients as feeling like a scratching sensation. In fact, a study published in Anaesthesia & Analgesia* found that the sensation caused by microneedling was indistinguishable from that of a smooth surface! However, it is possible for some to find the microneedling process uncomfortable.

Depending on the depth of microneedling treatment that you choose, a local anaesthetic cream can be applied to the treated area to minimise discomfort throughout the process.

Is microneedling safe?

Microneedling is considered to be a safe, minimally invasive procedure that when performed by qualified practitioners, nurses and doctors, is very well tolerated in patients. As with any aesthetic treatment, there are a number of side effects that generally resolve soon after the procedure. These include temporary redness of the treated area, itching and a small amount of bleeding around the puncture sites.

The best way to ensure that your microneedling procedure is performed in the safest way possible is to visit a clinic that is regulated by a professional body such as sk:n. In order for this to be the case, the treatment must be administered by a qualified nurse, dentist or doctor.

Should microneedling be carried out at home?

Microneedling at home presents a range of problems. Firstly, the equipment available for home use involves needles that are both shorter and blunter than those in specialist equipment. This makes for a less effective, more painful microneedling experience overall. Secondly, when microneedling is performed outside of the clinical environment, the risk of infection is increased. This is a consequence of both inadequate sterilisation and suboptimal technique.

Microneedling results

“I had acne for a couple of years and it’s left a lot of scarring on my cheeks. It made me feel very self conscious about myself. Having microneedling on my face has definitely improved the texture of my skin and I feel that i’ve gained more confidence.” – Microneedling before and after 3 sessions


Microneedling results depend on the reason for treatment, the extent of scarring or depth of wrinkles, and the number of sessions that have been completed. A clinical study published in The Journal of Plastic and Reconstructive Surgery investigated the efficacy of microneedling in 120 patients with scarring. This study found that all scars improved by at least 50% following treatment and 65% of patients experienced an improvement of more than 75% [1].

Many clients achieve exceptional results with microneedling at sk:n and we have a library of before and after images that can be viewed either on our website or at your free no obligation consultation. In order to maximise and maintain the results achieved by microneedling, regular treatments are required. The expected number of treatments needed to achieve your desired results will be discussed at your consultation. Booking a consultation also provides an opportunity to ask any questions that you might have about microneedling and decide on which procedure is most appropriate for achieving your goals.
