Pico laser delivers energy in pulses measured in trillionths of a second.

Pigment work is the part of our practice that demands the most patience and the most honesty. Melasma in particular is chronic and hormone-driven; it relapses. What Pico does, alongside prescription topicals and non-negotiable sun protection, is bring it down and keep it manageable.
