Laser Skin Resurfacing: Types, Costs & Who It's For

What Is Laser Skin Resurfacing?

Laser skin resurfacing uses focused light energy to either vaporize (ablate) or thermally injure the outer layers of skin without removing them. Both approaches trigger the body's wound-healing cascade — stimulating fibroblast activity, increasing collagen and elastin synthesis, and revealing fresher skin as old cells are cleared. The result, when successful, is visibly smoother texture, reduced wrinkles, improved tone, and more even pigmentation.

It is one of the most rigorously studied cosmetic procedures in dermatology, with a substantial body of peer-reviewed clinical data going back decades. It is also one of the more demanding in terms of patient selection, pre-procedure preparation, and post-procedure care. Understanding the differences between laser types — and which one is appropriate for your skin — is the most important decision to make before booking a consultation.

The Three Categories of Laser Resurfacing

1. Ablative Lasers — Maximum Impact, Maximum Downtime

Ablative lasers vaporize the epidermis and superficial dermis. The two main ablative wavelengths are:

CO2 laser (10,600 nm) The gold standard for dramatic photoaging reversal. Modern CO2 devices deliver energy in short ultrapulsed bursts or in scanning patterns that achieve 20–60 µm of tissue vaporization per pass with 100–150 µm of surrounding thermal damage. Clinical studies report wrinkle improvement of up to 90% with full-field CO2 ablation.

• Downtime: 14–21 days (full field); 4–10 days (fractional CO2)
• Best for: Deep wrinkles, significant photoaging, severe acne scars in fair skin
• Main risks: Persistent erythema (up to 1 year), post-inflammatory hyperpigmentation, hypopigmentation in darker skin types

Er:YAG laser (2,940 nm) Erbium lasers absorb water approximately 16 times more efficiently than CO2, delivering precise 3–5 µm ablation per pass with only 10–40 µm of collateral thermal injury. This precision means less dermal heat — faster healing, less risk of pigment changes, and often adequate topical anesthetic rather than sedation. A comparative trial with CO2 demonstrated equivalent efficacy with a trend toward more rapid recovery.

• Downtime: 3–8 days (full field); 1–3 days (fractional Er:YAG)
• Best for: Superficial to moderate photoaging, darker skin tones (Fitzpatrick III–IV)
• Main risks: Less thermal stimulation than CO2 may mean less collagen remodeling for deep wrinkles

2. Non-Ablative Lasers — Minimal Downtime, Gradual Results

Non-ablative resurfacing delivers heat to the dermis while leaving the epidermal surface intact. There is no open wound, no scabbing, and recovery is typically measured in hours to a day of redness rather than weeks.

The tradeoff is results: non-ablative lasers produce mild to moderate improvements and typically require 4–6 sessions to approach what a single ablative treatment achieves. Common non-ablative devices include the 1,064 nm Nd:YAG and 1,320 nm Nd:YAG, as well as the 1,450 nm diode.

• Downtime: Hours to 1 day
• Best for: Mild photoaging, patients who cannot afford extended downtime, maintenance treatments
• Results: Gradual; multiple sessions required

3. Fractional Lasers — The Middle Path

Fractional photothermolysis (coined in 2004) changed the field by delivering laser energy not as a contiguous beam across the entire skin surface but as thousands of microscopic treatment zones separated by columns of unaffected skin. These microscopic zones function like pixels on a screen — the untreated skin surrounding each column accelerates healing of the treated zones.

The result is meaningfully faster recovery than full-field ablative resurfacing, with results that sit between non-ablative and traditional ablative in magnitude. Fractional CO2 studies show approximately 40–72% measurable improvement in volunteers. Fractional versions of both CO2 and Er:YAG devices exist, as do non-ablative fractional lasers (e.g., the 1,550 nm Fraxel Restore, which is FDA-cleared for photoaging, wrinkles, and acne scars).

Laser Types at a Glance

What Conditions Laser Resurfacing Treats

Laser resurfacing has the strongest evidence for:

• Photoaging — fine lines, wrinkles (perioral, periorbital, forehead), and skin laxity caused by UV exposure
• Acne scars — atrophic scars (icepick, boxcar, rolling) respond particularly well to fractional CO2 and Er:YAG; a dedicated guide to laser acne scar treatment covers this in depth
• Sun spots and lentigines — ablative and fractional resurfacing clears epidermal pigmentation effectively
• Uneven skin tone and texture — generalized photoaging-related roughness and dyschromia
• Actinic keratoses — ablative resurfacing is an established field-treatment method for widespread sun-precancerous lesions
• Surgical and traumatic scars — fractional CO2 has a strong evidence base for scar remodeling

It is NOT an appropriate primary treatment for:

• Active acne with open inflammatory lesions
• Melasma (laser can worsen melasma; IPL or chemical peels are often preferred — see IPL treatment guide)
• Deep rhytides or significant skin laxity (better addressed by injectables or surgical lifting)
• Port-wine stains and vascular birthmarks (pulsed dye laser is preferred)

Who Is a Good Candidate?

Ideal candidates share several characteristics:

• Fitzpatrick skin types I–III for ablative non-fractional treatment; types IV–VI can consider fractional Er:YAG or non-ablative fractional approaches with experienced providers
• Realistic expectations — laser resurfacing improves, it does not eliminate; severe wrinkles or scars will be noticeably reduced, not invisible
• No active herpes simplex lesions (prophylactic antivirals are required even for asymptomatic patients with a history of cold sores)
• Willingness to commit to post-procedure care — consistent cleansing, barrier protection, SPF, and sun avoidance for weeks after the procedure

Absolute and Strong Relative Contraindications

What to Expect: The Procedure

Laser resurfacing is performed as an outpatient procedure. For a partial face treatment, expect 30–45 minutes; a full face typically takes 1.5–2 hours. Topical anesthetic cream is applied 30–60 minutes before the procedure. For more aggressive full-field CO2 treatment, oral sedation or local nerve blocks are common.

During the procedure, a trained provider passes the laser handpiece systematically over the treatment area. Patients report a warming or snapping sensation with non-ablative devices; ablative procedures under anesthetic are not painful during the session but have a meaningful post-procedural discomfort window.

Pre-Procedure Preparation

Your dermatologist or plastic surgeon will typically advise:

• Antiviral prophylaxis — starting 1–2 days before any ablative procedure; continued for 7–10 days post-treatment
• Hydroquinone pre-treatment — for patients with Fitzpatrick types III–IV or any history of post-inflammatory hyperpigmentation, a hydroquinone course of 4–6 weeks pre-procedure is often prescribed to reduce pigment risk
• Discontinue retinoids — stop prescription tretinoin 1–2 weeks before the procedure; OTC retinol 5–7 days before
• Strict sun avoidance for 2–4 weeks before treatment
• No waxing, bleaching, or chemical peels in the 2 weeks immediately preceding

Recovery Timeline

Recovery varies substantially by laser type and aggressiveness.

Ablative Full-Field CO2

• Days 1–3: Significant swelling, oozing, and crusting. Non-stick dressings or petroleum-based ointments to keep the treated skin moist. Sleep elevated.
• Days 3–7: Crusting begins to shed; new pink/red skin is visible beneath. Cleanse gently 2–5 times daily with mild cleanser as directed.
• Days 7–14: Re-epithelialization complete for most patients; skin remains bright red and sensitive.
• Weeks 2–6: Erythema gradually fades; SPF 30+ is non-negotiable from the moment the skin is re-epithelialized.
• Months 2–3: Most erythema resolved; collagen remodeling continues for 3–6 months. Results continue improving throughout.
• Up to 1 year: Residual redness can persist in some patients.

Fractional CO2 or Er:YAG

• Days 1–3: Redness, mild swelling, pinpoint oozing at treatment zones. Significantly less intense than full-field.
• Days 3–7: Micro-scabs shed. Bronzed or rough texture as old skin clears.
• Day 7: Most patients are socially acceptable for return to work with makeup.
• Weeks 2–8: Continued collagen remodeling; gradual improvement in texture and tone.

Side Effects and Risks

Common, expected:

• Redness (erythema) — universal; duration varies from days (non-ablative) to months (full-field CO2)
• Swelling — prominent first 2–3 days post-ablative treatment
• Dryness, peeling, and flaking — normal during re-epithelialization
• Milia (small keratin cysts) — can develop in the weeks after ablative resurfacing; treated with gentle extraction

Potentially serious:

• Post-inflammatory hyperpigmentation (PIH) — particularly in Fitzpatrick types III–VI; managed with pre-treatment hydroquinone, diligent SPF, and sometimes topical retinoids during healing
• Hypopigmentation — permanent depigmentation; more common with aggressive full-field CO2, especially in darker skin
• Herpes simplex reactivation — can occur even with prophylaxis; requires prompt antiviral treatment if blisters appear
• Bacterial infection — if wound care protocols are not followed
• Scarring — rare with experienced providers; risk increases with inappropriate settings, inadequate wound care, or use in contraindicated patients
• Ectropion — lower eyelid pulling downward; rare, associated with over-aggressive periorbital treatment

How Long Do Results Last?

Laser resurfacing does not stop the aging process. The collagen and elastin stimulated by the procedure will continue to degrade with time and UV exposure. Most patients enjoy results for:

• Non-ablative fractional: 1–2 years of noticeable improvement; annual maintenance sessions are common
• Ablative fractional: 2–5 years; single sessions often sufficient until significant new photoaging develops
• Full-field ablative CO2: 5–10+ years in many patients, though aging continues; some patients return for touch-up procedures

The single most important longevity factor is daily broad-spectrum SPF 30+ use. UV exposure is the primary driver of the photoaging that resurfacing reverses; resuming unprotected sun exposure will erode results.

Cost Overview

Laser skin resurfacing costs depend on the type of device, geographic location, provider expertise, and extent of treatment area. General reference ranges based on published reports:

• Non-ablative fractional: $800–$2,500 per session (multiple sessions typically needed)
• Ablative fractional CO2: $1,500–$4,000 per session
• Full-field ablative CO2: $2,000–$6,000+ per full face session

These procedures are classified as cosmetic and are not covered by health insurance in most cases. Exceptions may apply when treating pre-cancerous actinic keratoses or medically significant scars — verify with your insurer.

How to Choose a Provider

Laser resurfacing is a medical procedure, not a beauty treatment. Device settings, technique, pre-procedural assessment, and post-procedural care all significantly affect outcomes. Look for:

• A board-certified dermatologist or plastic surgeon with documented experience in the specific device to be used
• A provider who performs a thorough Fitzpatrick type assessment and discusses your scar history, recent medication history (especially isotretinoin), and herpes simplex history before any procedure
• A practice that provides detailed written aftercare instructions and a point of contact for post-procedure concerns

Medspa or salon environments that offer laser resurfacing without physician oversight carry meaningfully higher complication risks — particularly for hyperpigmentation in darker skin tones and for herpes reactivation.
