Hair-Removal Prep: Shaving, No-Waxing and Sun Rules on a Timeline
The Core Checklist
- Shave (within 24-48 h): remove the shaft, keep the follicle — surface hair steals energy and burns epidermis while wasting the pulse. Shave only, never pluck: waxing, tweezing and depilatory creams remove the melanin target, banned 2-4 weeks before and throughout the course (see follicle cycling).
- Clean skin: nothing on the skin — sunscreen, lotions and antiperspirant scatter energy and raise burn risk; no body products that day.
- Sun management: no visible tanning on the area for 4 weeks; tanned skin means derating or postponing (tanning and timing).
- Stop irritants: no acids, scrubs or retinoids on the area for 3-5 days.
- Disclosure: photosensitizing meds, tattoos and moles (avoid or special settings), recent treatments.
Area Differences
- Face: avoid active acne zones; conservative perioral settings.
- Bikini: extra hygiene prep and separate consent (bikini entry).
- Male beard/back: large areas — plan arrival time and changing flow in advance.
FAQ
Why do some sources say keep 1-2 mm stubble?
A habit from older devices without contact cooling that used the shaft for targeting; modern cooled systems target the follicle, so clean-shaven is safer and more efficient. Follow your device’s manual.
Arrived unshaved?
Most clinics shave on site (free or for a fee) or reschedule — firing over surface hair is improper practice and the clinic should refuse it.
