Laser hair removal works by targeting pigment in the hair shaft and follicle. The 6 weeks before each session matter — certain hair-removal methods, sun exposure, and topical products can make the treatment less effective or unsafe.
6 weeks before
- Stop waxing, plucking, threading — these remove the hair from the follicle, leaving nothing for the laser to target
- Stop electrolysis on the same area
- Don't switch to a fake tan
These are the most important weeks. The follicle needs hair present for the laser to work.
2 weeks before
- No tanning bed, no sunbathing — increased melanin in skin = increased burn risk
- Stop topical retinoids on the area
- Stop AHAs/BHAs on the area
- No bleaching cream on the area
Day before
- Shave the area cleanly — laser needs no hair above the skin to maximize energy delivery to the follicle
- Don't apply any makeup, lotion, or self-tanner on the area
- No heavy alcohol
Day of treatment
- Arrive shaved, clean, no products
- Drink water — hydration helps tolerance
- Eat something — light-headedness during treatment is rare but possible
- Wear loose clothing over treated areas
- Bring sunscreen for after
Hormonal considerations
Hormonal changes (pregnancy, hormonal birth control changes, PCOS) can cause new hair growth that wasn't present at treatment baseline. Tell your provider about hormonal events between sessions.
PCOS specifically may require more sessions and adjunctive medical management.
What's safe to use
Razor (clean shave the day before). Mineral SPF on the area between sessions. Gentle cleanser. Avoid anything with active ingredients (acids, retinoids, vitamin C) on the treatment zone.
Body location-specific notes
- Face (upper lip, chin): avoid camouflaging facial hair products like hair-darkening creams
- Bikini: shave carefully day before; avoid waxing 6 weeks pre
- Legs: stop shaving 1 week before for hair to grow long enough for laser detection
- Back: need to be shaved cleanly day before, often by partner or salon
Medications to discuss
- Retinoids (Accutane): postpone laser 6+ months post-isotretinoin
- Antibiotics (some increase photosensitivity): discuss with consultation
- Photo-sensitizing supplements: St. John's Wort etc. can increase risk
What goes wrong if you don't follow
- Tan skin → burns, hyperpigmentation
- Recently waxed → laser hits no hair, session wasted
- Active retinoid → sensitivity, blisters
- Sun exposure post-treatment → hyperpigmentation
Between sessions
6-8 weeks between sessions for typical hair growth cycle. Continue strict SPF 50+ between sessions on treated areas.

Standard protocol: 6–8 sessions spaced 4–8 weeks apart depending on body area, then maintenance as needed. At Elyzea, the diode platform is genuine, the operator is trained on protocols for all Fitzpatrick types, and the price list is transparent for each body zone.

Why Elyzea is different in Lima
Beyond the device, what changes outcomes is the clinical setup: an MD anesthesiologist on-site when protocols require it, a private recovery room, and a surgeon-led treatment plan. Plan your visit.
