PMU (permanent makeup) and SPMU (semi-permanent makeup) are both forms of cosmetic tattooing designed to enhance brows, lips, and eyeliner. The key difference lies in pigment depth and longevity—PMU can last 2–5 years with fewer touch-ups, while SPMU offers a softer, more natural look that fades in 1–3 years. Both are customizable to your beauty goals.
