Why you need a laser patch test
A free 15 minutes that keeps your laser treatment safe and effective.
Quick answer: A patch test checks how your skin and hair respond to the laser so settings can be personalised. It is free at Skin Deep and should be done at least 48 hours before treatment.
What happens
We review your medical history and medication, then test a small area.
Why 48 hours
Some reactions take time to show, so we wait before full treatment.
Before your test
Avoid sun and fake tan for two weeks and shave the test area the day before.
Medication
Some medicines increase light sensitivity, so tell us everything you take.
Common questions
Does the test cost anything?
No, it is free.
