Who Shouldn’t Get Laser Resurfacing?
Patient selection is part of good care — and sometimes the right answer is ‘not now,’ or ‘not this.’
Laser resurfacing is powerful, which is exactly why it isn’t right for everyone, or for every moment. Thoughtful patient selection is one of the most important safety steps in aesthetic medicine — and a provider willing to say ‘not now’ or ‘not this treatment’ is protecting your result, not withholding it.
Some reasons to hold off are temporary: they change when treatment makes sense. Others call for careful, individualized judgment about device choice, settings, or whether laser is the right tool at all. This page is an honest orientation — not a substitute for an in-person assessment.
Why Selection Matters
A provider willing to say ‘not now’ is protecting your result — not withholding it.
At A Glance
Candidacy, Simplified
A quick orientation to the situations that commonly affect laser candidacy. Most are nuanced — which is the point.
Laser candidacy at a glance
A quick orientation — your actual candidacy is always determined in person
Often a reason to postpone
- Active cold sore or skin infection in the area
- Recent significant sun exposure or a fresh tan
- Recent isotretinoin (Accutane) use
- Pregnancy or breastfeeding
- Unrealistic expectations for a single session
Needs careful, individualized judgment
- Richer skin tones (higher pigment-change risk — device & settings matter)
- A history of keloid or hypertrophic scarring
- Melasma (laser can sometimes worsen it)
- Certain medications or medical conditions
- Active inflammatory skin disease in the area
Educational summary only — not a substitute for assessment. Many items are temporary and simply change when, not whether, treatment is appropriate.
The DetailsReasons to Pause or Reconsider
These are among the most common factors that affect candidacy. Many are temporary and simply change the timing:
Active infection or cold sores
Treating over an active cold sore or skin infection risks spreading it; this is postponed and, for cold-sore-prone patients, often pre-treated preventively.
Recent sun or tanning
A fresh tan or recent significant sun exposure raises the risk of pigment problems; treatment waits until the skin settles.
Recent isotretinoin
Recent use of isotretinoin (Accutane) can affect healing; a waiting period is typically observed.
Richer skin tones
Not a disqualifier — but device choice and settings matter greatly to reduce the risk of post-inflammatory hyperpigmentation.
Keloid / scarring history
A tendency toward keloid or hypertrophic scars calls for caution and careful discussion.
Melasma
Laser can sometimes worsen melasma; it’s approached cautiously, and often other treatments come first.
Our ApproachHow Candidacy Is Decided
Candidacy isn’t a simple yes or no — it’s a judgment that weighs your skin type, pigment risk, health history, medications, the concern you want treated and the timing. The goal is a safe, natural result, which sometimes means adjusting the plan, choosing a gentler device, treating something else first, or waiting.
Timing problems vs. fit problems
Many ‘reasons not to’ are really timing issues — an active cold sore, a recent tan, recent isotretinoin — that resolve, after which treatment becomes appropriate. Others are fit issues, where a different treatment may serve you better than laser.
When we recommend something else
If laser would create undue risk or wouldn’t serve your goal, we’ll say so and suggest an alternative — whether that’s a different device, a medical skincare plan, or a non-laser approach. That clarity is part of the Onassis Skin Health philosophy: understanding when a treatment is worth doing at all.

Honest Counsel
Sometimes the most responsible recommendation is a different treatment — or none.
How We DecideEvidence-Based Practice
Aesthetic medicine changes rapidly, and novelty alone is not evidence. At Onassis Skin Health, treatment and skincare protocols are developed with reference to peer-reviewed medical literature and respected clinical guidance — then interpreted for the individual in front of us.
Research does not replace clinical judgment. It informs it.
Published evidence is read in the context of your anatomy, skin type, medical history, risk profile, lifestyle and desired outcome. Product and technique selection, dosing or placement, and pre- and post-care all follow from that combination of evidence and individualized assessment — not from what is simply popular or available for purchase.
When AppropriateIf Laser Isn’t Right, What Is?
When laser isn’t appropriate or well-timed, other paths can still move you toward your goal:
Medical Skincare
A prescriptive regimen can address many concerns directly, or prepare the skin for future treatment.
Non-Ablative Options
Gentler, lower-risk approaches may suit patients who aren’t candidates for ablative resurfacing.
Treating the Cause First
For issues like melasma, addressing the underlying process before considering any device is often wiser.
Combinations are recommended only when each element contributes meaningfully to your goals. Sometimes the right plan is a single, well-chosen treatment — and sometimes it is choosing not to treat at all.
The Bottom LineHow to Find Out for Certain
The only reliable way to know whether laser resurfacing is right for you — and right now — is an in-person assessment of your skin, history and goals. If you recognize yourself in any of the situations above, it doesn’t necessarily mean ‘never’; often it simply means ‘let’s talk about timing and the safest approach.’
QuestionsFrequently Asked
Does richer skin tone mean I can’t get laser?
No — but device choice and settings are especially important to reduce the risk of pigment changes, so individualized care matters.
I get cold sores — can I still have laser?
Often yes, with preventive treatment beforehand; active outbreaks are postponed.
How long after Accutane can I get laser?
A waiting period is typically observed; the exact timing is individualized and discussed at assessment.
Can laser treat my melasma?
Sometimes, but laser can worsen melasma, so it’s approached cautiously and often after other treatments.
What if I’m not a candidate right now?
Many reasons are temporary; we’ll advise on timing, or recommend an alternative that fits your goal.
