The look of the eyebrows can be improved or changed using both microblading and permanent cosmetics. The two methods do differ in several significant ways, though.
In permanent makeup, which is often referred to as cosmetic tattooing or micro-pigmentation, pigment is deposited into the skin using a tattoo machine or a hand tool.
Using a handheld instrument, microblading—also referred to as brow embroidery or feathering—creates tiny, hair-like strokes in the skin.
Both methods can produce gorgeous, realistic-looking brows, but they each have unique advantages and disadvantages. The best course of action for you should be determined in consultation with a knowledgeable and professional artist.
