One of the best things about laser hair removal is how minimal the downtime truly is. Unlike more intensive aesthetic treatments, you can typically return to your normal routine the same day. But "minimal downtime" doesn't mean "no preparation required."
Before Your Treatment
Proper preparation ensures both safety and optimal results.
Sun Exposure: The Critical Rule
Avoid direct sunlight, tanning beds, and self-tanning products for at least one week before treatment. Here's why: lasers target melanin, and melanin exists both in hair follicles (where we want the laser to work) and in tanned skin (where we don't).
If your skin has recent sun exposure or self-tanner buildup, we may need to postpone your treatment to avoid complications.
Shave, Don't Wax
Shave the treatment area within 24 hours of your appointment. This allows the laser energy to focus on the hair follicle beneath the skin rather than burning surface hair.
Do not wax, pluck, or use epilators for at least four weeks before treatment. These methods remove the hair root that the laser needs to target.
Medication Considerations
Stop topical acne medications (retinoids, benzoyl peroxide) at least 7 days before treatment. If you take oral Accutane, you'll need to wait at least one year after discontinuing before laser hair removal is safe.
During Treatment
Sessions typically last 20-45 minutes depending on the treatment area. Smaller areas like the upper lip take just a few minutes; larger areas like the back take longer.
Most patients describe the sensation as a rubber band snapping against the skin, followed by a warm feeling. Modern lasers incorporate cooling technology that significantly improves comfort.

Immediately After
Expect some redness and mild swelling—similar to a light sunburn. This typically subsides within a few hours to a day. Some patients experience mild tenderness for a day or two.
What to Avoid Post-Treatment
- Sun exposure: Avoid for at least two weeks; wear SPF 30+ when outdoors
- Heat exposure: Skip hot showers, saunas, and intense exercise for 48 hours
- Irritating products: Avoid retinoids, exfoliants, and fragranced products on treated areas for a few days
The Results Timeline
Results aren't immediate—and that's normal. Here's what to expect:
- Days 1-14: Treated hairs begin to shed (don't mistake this for new growth!)
- Weeks 2-4: The treatment area looks clearer as dead hairs fall out
- Weeks 4-8: New growth cycle brings untreated hairs to the surface—time for your next session
Most patients need 6-8 sessions spaced 4-8 weeks apart for optimal results. Hair grows in cycles, and laser can only treat follicles in the active growth phase.
