I was curious to try these pigments after seeing a ton of clients coming in for color corrections. I started researching why brows turn gray and red because "that's normal" wasn't acceptable to me. I came across Reverence Beauty and loved how this pigment was backed by science. Sure enough, no more gray/red brows!! No carbon base = no gray! I'm shook! I use the pigments for both machine work and microblading. I LOVE the thickness and consistency of the pigments and I can easily add thinner for machine work. The colors are so easy to dispense too! The packaging makes it so easy to use and it's mess free. Best of all, these inks are HIGHLY pigmented!! Sessions are sooo much faster now. I totally recommend this to trained artists committed to providing their clients with their dream brows.
