Laser Hair Removal Aftercare: Sun, Waxing, and What to Avoid Between Sessions
Quick Answer: After a laser session: avoid sun exposure, hot showers, gyms, saunas and swimming for 48 hours; apply sunscreen daily; moisturise; and never wax, thread, or pluck between sessions — only shave. Following aftercare correctly is the difference between finishing in 6 sessions versus 10.
First 48 Hours: The Critical Window
Your skin has absorbed controlled heat. For two days:
- No heat: hot showers, saunas, steam, cooking over open flames for long periods, intense workouts. Heat + treated skin = irritation and rare blister risk.
- No friction: tight clothing over treated areas; choose loose cotton.
- No actives: retinol, AHA/BHA, vitamin C, bleach, or scrubs on the treated area.
- Soothe: aloe gel or the calming cream your clinic recommends; cold compress if warm or pink.
Mild redness and follicle bumps (perifollicular oedema) for a few hours to a day are normal — they're a sign follicles absorbed energy.
Days 3–21: The Shedding Phase
Treated hairs don't vanish instantly — they shed over 1–3 weeks, often looking like slow regrowth first. Do not panic and do not pluck; let them fall or gently exfoliate after day 5. Plucking or waxing removes the root the laser needs to have destroyed — and sabotages the next session by pulling out hairs that would have shed anyway.
The Golden Rules Between Sessions
- Shave only. Never wax, thread, epilate, or pluck — these remove the follicle target.
- Sunscreen daily, SPF 50 on exposed treated areas. Tanned skin forces the next session to lower, less effective settings.
- No bleaching treated areas — laser needs the hair's pigment.
- Keep the schedule. 4–6 week gaps, no long delays.
- Tell your clinic about new medications — some antibiotics and acne medications cause photosensitivity, and sessions are rescheduled around them.
When to Call the Clinic
Blistering, crusting, persistent burning beyond 24 hours, or any pigment change warrants a call — one more advantage of a doctor-led clinic: a dermatologist reviews it the same day rather than a salon shrugging it off.
FAQs
Can I work out after laser? Wait 48 hours — sweat and heat on treated skin cause irritation and folliculitis.
Can I shower after a session? Yes, lukewarm only, no scrubbing, same day is fine.
Why do I look like I have MORE hair a week later? That's the shedding phase — treated hairs pushing out. It clears within 2–3 weeks.
Can I apply makeup after facial laser? Next day is safest; mineral makeup if the skin is calm.
What if I accidentally waxed between sessions? Tell your clinic — they'll likely space your next session to let follicles regrow so the laser has a target.
