What does a laser hair removal appointment look like? January 24, 2023 Before your appointment, we will instruct you to avoid prolonged sun exposure and ensure you have not taken any antibiotics 2 weeks prior to treatment. The day of your laser hair removal treatment in Houston at Studio Essex, your medical aesthetician will apply a topical anesthetic to your desired treated area. This will ensure you will remain as comfortable as possible throughout the entirety of your treatment. We will then start applying bursts of laser technology using the Icon™ Aesthetic System onto your desired treated area. Each treatment session typically takes under an hour to complete.
