Q: How do you use a nail buffer block?
A: Work through the sides in order, coarsest first, using light strokes in one direction. The final side is the one that brings up the shine.
Q: How often should you buff your nails?
A: Once a month is plenty. Buffing thins the nail plate slightly each time, so more often than that leaves nails weaker rather than shinier.
Q: Does buffing damage your nails?
A: Not occasionally and lightly. Damage comes from buffing hard or too often, which thins the surface. Light pressure and a monthly rhythm keeps nails strong.
