Laser Treatment Aftercare: Your Hour-by-Hour Recovery Guide

laser treatment aftercare

Laser treatments are among the highest-stakes procedures in medspa practice — not because they are dangerous when performed correctly, but because the quality of recovery dramatically affects the final result. I have consulted with practices across the US and watched the same pattern repeat: excellent laser work, mediocre aftercare instructions, disappointed patient. This guide fixes that. It covers laser treatment aftercare for the most common modalities: ablative resurfacing (CO2, Erbium), non-ablative treatments (IPL, Clear + Brilliant, Halo in non-ablative mode), and vascular and pigment lasers.

If you are a provider reading this, use it as a starting point for your patient education materials. If you are a patient, follow these rules and your results will speak for themselves.

Pre-Treatment Preparation: What to Do Before Laser

Do This Before Your Laser Appointment

• Begin a skincare prep protocol four to six weeks before ablative laser if your provider recommends it — typically a retinol or tretinoin regimen to pre-condition the skin, followed by a pause period before the procedure itself.
• Use broad-spectrum SPF 30 or higher every day for at least four weeks before laser treatment. Sun damage and active tanning are contraindications for most laser procedures.
• If you are prone to cold sores, talk to your provider about prophylactic antivirals. Ablative laser can trigger an outbreak, and your provider may prescribe valacyclovir starting one to two days before treatment.
• Stay well-hydrated in the week before treatment — hydrated skin heals more efficiently.
• Arrive with a thoroughly clean face. Remove all makeup, sunscreen, and skincare products before arriving or immediately upon arrival.
• Arrange a ride home if you are having ablative laser or if your provider is using sedation or strong topical anesthetic — you may not be comfortable driving.

Avoid Before Your Laser Appointment

• No tanning — including self-tanner, spray tan, UV beds, and direct sun — for at least four weeks before ablative laser and two weeks before non-ablative treatments.
• Stop retinol and tretinoin three to five days before treatment (your provider will specify the exact window).
• No exfoliating acids (AHA, BHA) for 48 hours before treatment.
• No Botox or filler within two weeks before ablative laser — schedule neuromodulators after laser, not before.
• Avoid waxing, threading, and depilatory creams on the treatment area for at least one week before.
• No NSAIDs (ibuprofen, aspirin) for seven days before if your provider recommends pausing — ablative laser does not carry the same bleed risk as injectables, but reducing systemic inflammation is still beneficial.
• Disclose all medications to your provider — certain antibiotics (tetracyclines, fluoroquinolones) and other medications increase photosensitivity and may be contraindications.

Laser Treatment Aftercare: The First 24 Hours

The first 24 hours after laser treatment are the most critical for healing. The protocols differ slightly between ablative and non-ablative, but the core principles are the same.

0–4 Hours Post-Treatment

• Your skin will be red, warm, and sensitive — this is expected. For ablative treatments, expect oozing and significant swelling in addition to redness.
• Apply the occlusive or healing ointment your provider gives you (commonly Aquaphor, petrolatum, or a medical-grade healing balm) as directed. Do not let the skin dry out.
• Use a cool (not ice-cold) clean cloth to gently press — not rub — the skin if it feels intensely hot. Do not apply ice directly.
• Stay indoors and out of direct light. No sun exposure of any kind.
• Take any oral medications your provider prescribed — often antivirals, antibiotics for ablative procedures, and pain management as directed.

4–12 Hours Post-Treatment

• Continue applying healing ointment as directed — for ablative laser, the skin needs to stay moist continuously during the healing phase.
• Sleep on a clean pillowcase, preferably silk or satin, with your head elevated to reduce swelling.
• Avoid touching your face unnecessarily. Everything that contacts the skin should be clean.
• Do not pick at any skin that begins to flake, peel, or crust — premature removal disrupts healing and increases scarring risk.

12–24 Hours Post-Treatment

• Gentle cleansing with lukewarm (not hot) water and a fragrance-free gentle cleanser if your provider has cleared this — some ablative protocols recommend waiting 24 hours before cleansing.
• Pat dry with a clean soft cloth or sterile gauze — never rub.
• Reapply healing ointment immediately after any cleansing.
• Swelling may increase in the first 24–48 hours before it begins to decrease — do not panic.

Laser Treatment Aftercare: 24–48 Hours

• For non-ablative treatments (IPL, Clear + Brilliant, mild Halo): redness typically begins resolving significantly in this window. You may return to work wearing mineral SPF but no other active skincare.
• For ablative treatments: you are still in active healing. Skin may be weeping, crusting, or peeling. Keep it moist and protected. Do not force the healing process.
• Continue avoiding sun exposure with religious diligence — even brief unprotected sun exposure during the healing window can cause hyperpigmentation, especially in medium and deeper skin tones.
• No makeup on treated areas. Mineral powder makeup is sometimes cleared for non-ablative patients at 48 hours — confirm with your provider.
• No vigorous exercise — elevated body temperature, sweat, and friction aggravate healing laser skin.
• No hot showers — use lukewarm water only.
• Avoid all topical actives: retinol, vitamin C, glycolic acid, salicylic acid, and benzoyl peroxide.

Laser Treatment Aftercare: 48–72 Hours and Beyond

48–72 Hours

• Non-ablative patients: most redness has resolved. Begin gentle moisturizer (fragrance-free, non-comedogenic) and mineral SPF. Resume cleansing with gentle cleanser twice daily.
• Ablative patients: peeling or flaking typically begins in this window. Apply healing ointment continuously. Do not peel prematurely — let the skin shed on its own schedule.
• Stay out of direct sunlight entirely if possible. If you must be outdoors, wear a wide-brim hat and SPF 50+ physical sunscreen on all healed areas.

Week 1–2

• Non-ablative patients: resume normal skincare with provider approval at est. days 5–7. Retinol can often be reintroduced at two weeks.
• Ablative patients: peeling typically completes by day 7–10. The underlying skin will look pink, smooth, and sensitive. Introduce gentle cleanser and basic moisturizer. Save actives for week three or later.
• No waxing, threading, or dermaplaning on treated areas until fully healed (est. four to six weeks for ablative).
• No additional laser, RF, or energy-based treatment for a minimum of four to six weeks.

Long-Term Laser Aftercare

• Wear SPF 30 or higher every single day for est. three to six months post-laser — this is non-negotiable for protecting your results and preventing post-inflammatory hyperpigmentation.
• Avoid direct sun on the treated area for at least three months after ablative laser.
• Most providers recommend a mineral (physical) SPF containing zinc oxide or titanium dioxide for the first month post-treatment.

If you are a medspa evaluating how your laser aftercare protocols compare to top-performing practices, a medspa marketing audit is a useful starting point — I look at patient education and follow-up communication as part of every audit I conduct.

Red-Flag Side Effects After Laser Treatment

Expected After Laser

• Redness and warmth (sunburn-like sensation) for 24–72 hours depending on treatment intensity
• Swelling, especially around eyes, that peaks in the first 24–48 hours
• Peeling or flaking after ablative procedures (days 3–7)
• Temporary darkening of pigmented spots with IPL before they flake off (this is the treatment working)
• Mild itching as skin heals

Call Your Provider If You Experience

• Blistering, crusting, or open wounds in areas that were not expected to be ablated
• Increasing redness, warmth, pain, or swelling after day three (symptoms should be decreasing, not worsening)
• Fever above 101°F
• Pus, discharge, or signs of infection at the treatment site
• Burning rash with clusters of small blisters — this may indicate a herpes outbreak triggered by laser trauma
• Hyperpigmentation developing on the treated area (brown discoloration rather than pinkness) — this is treatable if caught early

Laser Aftercare by Treatment Type

Not all lasers are the same. Here is a quick breakdown of what recovery looks like for the most common modalities.

• CO2 laser (fully ablative): est. 7–14 days of downtime, significant peeling, keep skin continuously moist throughout healing.
• Erbium laser: est. 5–7 days downtime, less aggressive than CO2, similar principles apply.
• Halo (hybrid ablative/non-ablative): est. 3–7 days, MENDS (tiny dark dots) appear at days 2–3 and flake off by day 5–7 — this is normal and expected.
• Clear + Brilliant: est. 1–3 days minimal downtime, gentle protocol applies.
• IPL (Intense Pulsed Light): est. 1–5 days, treated spots darken before falling off — do not pick.
