Microblading: lasts 6- 18 months on average before needing a color boost.

Times just vary based on the individual. Everyone will hold differently depending on skin type, age, sun exposure, lifestyle, using retinols/acids or peels, etc. In order to achieve a more natural, realistic looking brow, the pigment is not implanted as deeply or as solid as a traditional tattoo, which is why more maintenance is required.
