Microblading is a semi-permanent cosmetic tattooing technique used to enhance the appearance of eyebrows. It involves creating fine, hair-like strokes using a special tool and pigment to mimic the look of natural eyebrow hairs. The results typically last around 1 to 3 years, depending on various factors such as skin type and aftercare. Before considering microblading, it's essential to research and find a skilled and experienced professional to ensure the best outcome.
