If your colour is very dark or previous shape is really uneven, we would recommend you to remove and redo. However, do send us a picture or your current eyebrow before we can advice u further.
Same like other embroidery process, we will apply numb cream before the treatment. During the process you may still feel slight burning or stinging as laser depending on the colour tone of your eyebrow.
Darker colour might experience stronger feeling as laser will go deeper into your skin to remove the color pigment.
It actually depends on your skin metabolism rate and your previous eyebrow color tone which varies individually. If your previous color has lasted you for many years and still very dark, then might require more sessions to fully remove the color.
If you wish to do full eyebrow laser, we would recommend you to go for non invasive laser as it does not require any healing period and you may wash your face or do make up 4 hours after the tretament.
As non invasive laser doesnt cause any wound or bleeding, you may need to visit more sessions (once every two weeks) to remove the eyebrow color.
It‘s not advisable to do so as the laser area will have wound and require at least 30 days for it to heal before it can go through another session. If laser too frequently may leave scar to the laser area.
If you dont mind going through more sessions you can actually wait until fully removed only redo your eyebrow. Otherwise, if your eyebrow colour has faded off around 70-80%, you may choose to do your eyebrow as well.
