Eyebrow embroidery is also known as eyebrow hairline stroke. Unlike eyebrow tattoos, it is semi-permanent and can last up to two years. By adding colored pigment to the skin, this technique fills in empty spots on your brows to give them a full and flawless look. Korean Eyebrow Embroidery is usually done for women with pale skin and light brow hair. The most common complaint is that the brow coloring is too dark. To make sure you get the best results possible, pre-select a color with your technician.
