What is a Patch Test for Laser Hair Removal?

When you attend the clinic for your initial consultation for laser hair removal, you will be required to undergo a ‘patch test’ prior to commencing your laser hair removal treatment. The purpose of the patch test is to determine a safe and effective setting of the laser for your skin and hair type. We would recommend waiting 24 hours after your patch test before undergoing your first laser hair removal treatment to ensure there is no adverse reaction.

Laser Hair Removal Treatment Close Up A range of settings will be used in the patch test, tailored to your individual skin and hair type, starting at a lower level and gradually increasing until a good clinical endpoint is achieved. We would expect to see slight reddening of the skin, some frazzled, burnt hairs and sometimes slight swelling around the hair follicles – giving a goosebumpy appearance. You will be able to feel a slight pinpricking sensation when the desired setting is achieved.

The patch test is only done on a very small area and will normally take only a few minutes. The skin usually recovers very quickly and you should experience no discomfort afterwards. Aloe vera would normally be applied to the skin afterwards to cool the area.

Consultations and patch testing are free of charge and only carried out by experienced, registered nurses at our London laser hair removal clinic.
