Ethos - SPS (Special Prep Solution)
SPS, or "Special Prep Solution", is a miracle prep solution that improves Gel adhesion on nails giving longer wear, helps make gel remover faster and easier, all while helping maintain a healthy moisture balance and leaving a healthier natural nail.
Prepare nail as normal and then apply SPS to the centre of each nail. Avoid flooding cuticles but allow SPS to spread to the sides of the nail. Proceed with overlay. You can watch an in-depth instructional video by Bio Sculpture founder, Elmien Scholtz.
