Most laser hair removal problems start before the appointment. A recent tan, a wax last week, or a retinol you forgot to pause can mean a lower setting or a rescheduled visit. Good laser hair removal prep takes about two weeks of small habits, and none of them are hard.
This guide covers shaving, sun, skincare, medications, and what to do on the day, based on the prep rules for a laser hair removal session at New Day Medspa in Jacksonville, FL.

Your prep checklist at a glance
- Stop waxing, threading, and tweezing at least 4 weeks before.
- Avoid sun, tanning beds, and self-tanner for 2 weeks before.
- Pause retinoids and exfoliating acids 5 to 7 days before.
- Skip alcohol for 48 hours before.
- Shave the area about 24 hours before.
- Arrive with clean, dry skin and nothing on it.
- Tell your provider about new medications and any recent sun exposure.
How should you shave before laser hair removal?
Shave about 24 hours before your session, not the morning of. The laser targets the pigment in the hair root, so shaving removes the part above the skin and leaves the root in place. Waxing, threading, and tweezing pull out the root, leaving the laser nothing to target.
Published Indian Journal of Dermatology, Venereology and Leprology guidelines say the same: patients shouldn't wax or pluck once treatment starts, and they can shave the area a day earlier. Skip depilatory creams too, since they irritate the skin the laser will treat.

How long should you avoid sun before laser hair removal?
Avoid sun, tanning beds, and self-tanner on the treatment area for 2 weeks before each session. Tanned skin has more pigment, and the laser can mistake it for hair. That raises the risk of irritation, so tanned skin often means lower settings or a rescheduled visit.
In Jacksonville, that is harder than it sounds. A weekend on the St. Johns, a beach afternoon, or a few lunch hours outside can all count. Cover the area with clothing, use SPF daily on exposed skin, and tell your provider about any recent sun exposure when you arrive. Fall and winter are the easiest seasons to start a series.
What skincare and products should you pause?
If you use a retinoid and aren't sure when you last applied it, ask. A provider would rather hear about it than treat irritated skin.
What medications and supplements should you tell your provider about?
Tell your provider about everything you take, including over-the-counter medicines like ibuprofen and aspirin, supplements, blood thinners, antibiotics, and anything that makes skin more sensitive to light. Some medications raise the risk of irritation, and your provider decides whether anything needs to change.
Isotretinoin deserves a specific mention. If you take it or took it recently, mention it at your consultation, because the waiting period is set by your provider and prescriber. Never stop a prescription on your own to prepare for laser.
What should you do on the day of your appointment?
- Arrive with clean, dry skin, with no lotion, oil, or deodorant on the area
- Skip makeup and heavy fragrance on or near the treatment area
- Wear loose clothing that gives easy access
- Bring a list of your medications and supplements
Preparation applies to every session in a series, not only the first. Starting a new series? Our Brazilian laser hair removal guide covers extra notes for that area.
What should you tell your provider before treatment?

- Previous laser or IPL treatments
