Skincare Before a Laser
Preparation is part of the treatment. The condition of your skin going into a laser session can influence how it responds and how smoothly it heals. Published expert guidance increasingly supports a prep phase for energy-based procedures — with attention to the skin barrier, pigmentation risk and sun exposure.
Prep is individualized to your skin, the laser and your pigmentation tendencies, and your specific instructions always come from your provider. The principles below explain the ‘why’ behind them.
The Overlooked Half
How you prep is as much about what you pause as what you apply.
At A Glance
Prep: Do and Pause
Good preparation is as much about what you pause as what you use.
Preparing your skin for laser
Individualized to your skin and laser — your provider’s instructions come first
Often part of prep
- Gentle, barrier-supporting skincare
- Sometimes pigment-regulating agents (esp. richer tones)
- Strict daily broad-spectrum sunscreen
- Good hydration and a calm barrier
- Pre-treatment for cold-sore-prone patients
Usually paused beforehand
- Retinoids (per your provider’s timing)
- Strong exfoliating acids
- Harsh scrubs or irritating actives
- Active tanning or sun exposure
- Waxing or irritation in the area
General principles only; exact products and timing are individualized and provided by your clinician.
Why It MattersWhat Prep Accomplishes
Thoughtful preparation supports a better, safer outcome:
A Calm Barrier
Starting with healthy, well-hydrated skin supports smoother healing.
Lower Pigment Risk
Pre-conditioning — especially in richer tones — can help reduce post-laser pigmentation risk.
No Fresh Tan
Treating recently sun-exposed skin raises risk, so sun avoidance beforehand is key.
Pausing Actives
Retinoids and acids are typically paused so skin isn’t pre-irritated.
Cold-Sore Prevention
Prone patients may be pre-treated to prevent an outbreak.
Realistic Timeline
Prep may begin in the weeks before treatment, depending on your plan.
The PlanHow Prep Is Guided
Your prep plan is matched to the specific laser, your skin type and your pigmentation tendencies. For some patients — particularly richer skin tones — a short course of pre-conditioning skincare is advisable; for others, simply calming the barrier and avoiding the sun is enough.
Pausing the right things
Strong actives like retinoids and exfoliating acids are generally paused on a timeline your provider sets, so the skin isn’t pre-irritated going in.
Then recovery
Prep and aftercare are two halves of the same plan — see skincare after laser and the recovery timeline.

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 AppropriatePart of the Whole
Preparation is one phase of a complete laser plan that includes:
+ In-Office Treatment
Skincare prepares, supports and extends the results of lasers and other procedures.
+ Photoprotection
Daily broad-spectrum sunscreen protects both your skin and your results.
+ A Simple, Followed Routine
The best regimen is the few right steps you’ll actually do — not the longest one.
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.
Good to KnowFollow Your Plan
Because prep depends on the laser, your skin type and your pigment risk, the specifics are always individualized — follow the instructions your provider gives you over any general advice. If you’re cold-sore-prone, richer-skinned, or using strong actives, let us know so we can prepare you appropriately.
QuestionsFrequently Asked
How far before laser should I prep?
It varies — sometimes a few weeks of pre-conditioning; your provider sets the timeline for your skin and laser.
Should I stop retinoids before laser?
Usually yes, on a timeline your provider gives, so your skin isn’t pre-irritated.
Why avoid the sun before treatment?
A fresh tan or recent sun exposure raises the risk of pigment problems, so treatment is done on calm skin.
Do I need special products first?
Sometimes — especially richer skin tones may benefit from pre-conditioning; others just need a calm, protected barrier.
What if I get cold sores?
Tell us — prone patients are often pre-treated to prevent an outbreak.
