Microblading is a tattooing technique which uses a small handheld tool made of several tiny needles to add semi-permanent pigment to the skin.[1] Microblading differs from standard eyebrow tattooing, a form of permanent makeup, as each hair stroke is created by hand with a blade that creates fine slices in the skin, whereas eyebrow tattoos are done with a tattoo machine. Microblading is used on eyebrows to create, enhance, or alter their appearance in shape and color. It deposits pigment into the upper region of the dermis, so it fades more rapidly than traditional tattooing techniques. Microblading is often referred to as eyebrow embroidery, eyebrow feathering, microstroking, 3D eyebrows, nanoblading or hair-like strokes.[2]
The technique of implanting pigment following fine incisions in the skin may date back thousands of years,[3] but the trend of using the technique for eyebrows is thought to have emerged in Asia, becoming popular in Singapore and Korea as early as 2005, and in Europe and the United States in 2010.[4] Microblading had become the most popular method of cosmetic eyebrow tattooing in Europe and the United States by 2015. Technique names such as 3D or 6D eyebrows were also popularized.[5]
The microblading procedure is a semi-permanent tattoo. Like all tattoos, microblading can fade, depending on multiple factors, including the quality of pigment/ink used,[6] UV exposure, skin type, elements found in skincare products, and/or medications. The treatment lasts from 18 to 30 months, although it can sometimes last for up to 3 years. A touch-up session is encouraged 6 weeks after the first microblading procedure, and every 12–18 months thereafter.[7]
Safety precautions for microblading are similar to those for any other tattooing technique. The most common complications and client dissatisfaction that result from any form of tattooing are a misapplication of the pigment, pigment migration, colour change, and in some cases, unintended hyperpigmentation.[8] Serious complications are uncommon. As with all forms of tattooing, the risks associated with microblading include the transmission of blood-borne pathogenic organisms (e.g. HIV, hepatitis C, staphylococcus aureus, herpes simplex), as well as short-term or long-term reactions to pigment ingredients.[9] There is the potential for granulomas to form on the tattooed areas as a result of the pigment, a foreign substance, being injected into the skin. Therefore, it is essential to verify that the technician holds the appropriate licenses and registrations for the provision of tattoo services, as well as inquire about the technician's standard of training. Procedures performed by technicians who have completed a comprehensive course of instruction[10] can minimize the risk of unwanted outcomes and client dissatisfaction.[11]
