Microneedling works by creating tiny punctures on the skin's surface with the help of a handheld device called a derma roller or a derma pen. These devices contain small needles that penetrate the first few layers of the skin, creating controlled micro-injuries that stimulate the body's natural healing response.
When the skin is injured, the body produces collagen and elastin, which are proteins that are essential for healthy skin, helping to plump it up and give it a more youthful appearance, while also improving its texture and tone.
Microneedling is typically performed in a clinical setting by a licensed professional, such as a dermatologist or an aesthetician, who will clean the skin, and then possibly apply numbing cream to the area to help minimise discomfort before the procedure starts.
During the procedure, the microneedling device is passed over the skin in a specific pattern, targeting the ‘problem’ areas and creating small punctures. Afterwards, the skin may be slightly red and tender, similar to a mild sunburn, but the recovery time is usually short, and patients can resume their normal activities within a few days.
Microneedling is a versatile treatment that can be used to address a variety of skin concerns, including fine lines and wrinkles, acne scars, hyperpigmentation, and uneven skin texture, and is one of the best options to help improve the overall appearance of the skin.
However, it is important to note that microneedling may not be the best choice for everyone. For example, I advise individuals with certain skin conditions, such as active acne or rosacea, to avoid microneedling as the trauma created may cause further inflammation, or their condition may make them more prone to infection or scarring. Additionally, those with a history of keloid scarring may need to avoid microneedling, as it can potentially worsen their condition.
While microneedling is generally considered safe when performed by a licensed professional, there are some risks associated with the procedure. This can include temporary redness, swelling, and bruising, as well as a slight risk of infection - this is why It is important to discuss these risks with a licensed expert before undergoing the procedure to ensure that it is the right choice for you.
