Short answer: not while they're on a photosensitising antibiotic — and many common ones are. Wait until the course is finished, then leave a buffer of at least 1–2 weeks before treating.
Several widely prescribed antibiotics make skin dramatically more reactive to light. The biggest offenders are the tetracyclines — doxycycline and lymecycline, both routinely prescribed for acne, so they turn up constantly in laser hair removal clients. Ciprofloxacin and trimethoprim can also photosensitise. Treating over them risks burns, blistering, and post-inflammatory hyperpigmentation — the exact injuries that generate complaints and insurance claims.
What to do in practice:
- Ask about medication at every appointment, not just the first consultation. Antibiotic courses are short and clients rarely think to mention them.
- If they're mid-course, rebook. Standard industry guidance is to wait 1–2 weeks after the final dose (some manufacturers say longer for tetracyclines — check your device protocol).
- If they've been on long-term lymecycline or doxycycline for acne, they need to speak to their prescriber before you treat. Do not work around an ongoing prescription.
- Record the medication, the decision, and the rebook date in the client's record. If a reaction ever occurs, your notes are your defence.
Your insurance almost certainly requires a medication check before every light-based treatment — skipping it can void cover. And a patch test after any medication change is non-negotiable.
Every client, remembered — safely.
