Absolute contraindications
Programs will not treat under any of these conditions:
| Condition | Why |
|---|---|
| Pregnancy | No safety data supports elective treatment during gestation. |
| Active skin cancer in treatment area | Requires oncology clearance. |
| Isotretinoin (Accutane) within past 6 months | Skin is more fragile and heals abnormally. |
| Active herpes simplex outbreak in treatment area | Risk of viral spread and delayed healing. |
| Active bacterial or fungal infection in treatment area | Compromises healing and can spread infection. |
| Recent gold-based systemic therapy | Permanent pigment change risk (chrysiasis). |
Situations that require deferral
These aren't permanent no's — they mean the specific session gets rescheduled:
- · Recent significant sun exposure or tanning (within 2 weeks).
- · Recent chemical peel, laser resurfacing, or microneedling in the area.
- · Sunburn, rash, or broken skin in the treatment area.
- · Recent botulinum toxin or filler in the treatment area (typically 2-week gap).
- · Active flare of eczema, psoriasis, or vitiligo in the treatment area.
- · Recent tattoo (permanent contraindication over the tattoo itself).
What deferral is not
Medications that matter
Photosensitizing medications increase how strongly your skin reacts to light — including laser light. Most don't disqualify treatment, but your provider needs to know about them so settings can be adjusted. Common categories:
- · Antibiotics (tetracyclines, sulfonamides, fluoroquinolones).
- · Certain antidepressants and antipsychotics.
- · NSAIDs in high, sustained doses.
- · Hormone therapies (both HRT and gender-affirming hormones).
- · Retinoids — topical (tretinoin) and oral. Topical retinoids just require a short pause; oral isotretinoin needs the 6-month gap.
- · St. John's wort and some herbal supplements.

How screening actually protects you
Screening isn't just an intake questionnaire. Every reputable program screens at three moments: at enrollment consultation, at the start of every session, and visually right before the first pulse. Anything new — a medication, a sunburn, a rash — resets the conversation.

Key takeaways
- · Pregnancy defers treatment throughout gestation and typically postpartum.
- · Isotretinoin (Accutane) requires a 6-month gap before laser treatment.
- · Photosensitizing medications must be disclosed at every session.
- · Active infections, sunburn, and unhealed skin defer treatment on that area.
- · Screening is a standing checklist — not a one-time intake question.
