3 to 6 weeks is safest. This allows the tissues to heal after Labiaplasty before having laser hair removal treatments. Waxing would be more injurious than laser hair removal. Of course the inner labia are far enough away from the laser energy, which would primarily be directed into the mons pubis and labia majora. This timeframe should allow safe laser hair removal done within about three weeks from Labiaplasty.
