The word "laser" covers a wide range of treatments with very different results, recovery times, and appropriate uses. Patients who come in for a consultation after reading about laser skin resurfacing online often have questions about a specific device or brand name, and the answer is usually: it depends on what you are trying to correct and how much downtime you can manage.
This guide explains the main categories of laser resurfacing available, what each one does well, and how to think about which approach might be appropriate for your skin.
Ablative vs. Non-Ablative Resurfacing
The most important distinction in laser skin resurfacing is between ablative and non-ablative treatments. This single factor determines more about your recovery experience and your results than any other variable.
Ablative lasers
Ablative lasers remove the outer layer of skin. The controlled removal triggers the body to produce new collagen and rebuild the skin surface. Results are significant and often long-lasting, but the tradeoff is a real recovery period. The skin weeps, crusts, and peels for several days. Full redness can persist for weeks.
CO2 and Erbium YAG are the two primary ablative laser types used in clinical practice. CO2 produces more dramatic results for deep lines and significant sun damage. Erbium YAG is slightly gentler, with a somewhat shorter recovery, and tends to be preferred for patients with moderate skin concerns or slightly more sensitive skin.
Non-ablative lasers
Non-ablative lasers deliver energy beneath the skin surface without removing the outer layer. The skin stays intact, which means recovery is much shorter, typically one to two days of mild redness. The results are also more gradual and subtle than ablative treatment. Most non-ablative protocols require a series of sessions rather than a single treatment to produce noticeable improvement.
Non-ablative treatments are appropriate for patients with mild to moderate skin concerns who cannot take significant downtime, or as maintenance between more intensive treatments.
Fractional Technology
Fractional lasers, both ablative and non-ablative, treat only a fraction of the skin surface in each session, leaving surrounding tissue intact. This approach preserves healing capacity, reduces recovery time compared to traditional full-ablative treatment, and allows treatment of areas that were once considered too risky for resurfacing.
Fraxel is the most widely known fractional device, though similar technology is available under various brand names. Fractional CO2 treatments occupy a useful middle ground: they produce meaningful improvement in texture and tone, with a recovery period of five to seven days rather than the ten to fourteen days associated with full ablative CO2 treatment.
What Laser Resurfacing Addresses
Laser resurfacing is most effective for:
- Fine lines and wrinkles, particularly around the eyes, mouth, and forehead
- Uneven skin tone from sun exposure, melasma, or post-inflammatory hyperpigmentation
- Acne scars, including rolling and boxcar scars
- Surgical or injury scars
- Rough or uneven skin texture
- Mild skin laxity, particularly as part of a broader rejuvenation program
Laser resurfacing does not significantly address volume loss, deep folds like nasolabial creases, or sagging that requires surgical correction. Patients with these concerns may benefit from combining resurfacing with fillers, fat grafting, or a facelift procedure, depending on the degree of change they are seeking.
Choosing the Right Laser for Your Skin
Several factors go into selecting the appropriate laser type and settings for a given patient.
Skin tone and Fitzpatrick type
Patients with darker skin tones face a higher risk of post-inflammatory hyperpigmentation from certain laser types, particularly traditional ablative CO2. A thorough assessment of skin tone is necessary before recommending any resurfacing treatment. In patients with Fitzpatrick III through VI skin, the approach to laser selection changes significantly, and some ablative protocols are contraindicated entirely.
Severity of skin concerns
Mild surface texture and early hyperpigmentation can often be addressed with non-ablative or fractional non-ablative treatments. Deeper lines, more established sun damage, and moderate to severe acne scarring generally respond better to fractional ablative or full ablative treatment. Trying to correct significant concerns with a gentle laser produces disappointment; treating mild concerns with a full ablative laser creates unnecessary recovery and risk.
Downtime tolerance
A patient who cannot take any time away from public-facing work should not undergo full ablative CO2 resurfacing. Matching the treatment to the patient's life is as important as matching it to their skin. A fractional non-ablative treatment series may produce slower, more modest results, but it is the right choice if ablative downtime is genuinely not manageable.
Active skin conditions
Active acne, rosacea flares, cold sores, and certain topical medications can affect laser candidacy and timing. Patients who have taken isotretinoin (Accutane) within the prior six months are generally not candidates for ablative resurfacing. A complete skin history is part of any legitimate laser consultation.
The Treatment Experience
Most laser resurfacing procedures are performed in an office or outpatient surgical suite. Topical numbing cream is applied prior to the procedure. For more aggressive ablative treatments, local anesthesia or sedation may be used.
The laser handpiece passes over the treatment area in controlled passes. The duration depends on the area being treated and the laser type. Full-face fractional CO2 treatment typically takes thirty to forty-five minutes. Non-ablative treatments on the full face are often completed in twenty to thirty minutes.
Immediately after treatment, the skin will appear red and may feel warm or tight. For ablative treatments, swelling is expected in the first day or two, particularly around the eyes.
Recovery: What to Expect
Recovery guidance varies by laser type, but several principles apply across all resurfacing treatments.
Sun avoidance is non-negotiable. Sun exposure on recently treated skin can cause hyperpigmentation and compromise results. Patients should plan to avoid direct sun exposure for several weeks after ablative treatment and use a broad-spectrum SPF 30 or higher daily for months afterward.
Moisturizing is active recovery, not optional comfort. Keeping the skin well-hydrated during healing reduces crusting, supports new skin formation, and minimizes the risk of scarring.
Do not pick or peel. Skin that peels or crusts on its own schedule is healing properly. Manual removal of crusted skin increases the risk of scarring and infection.
Plan your schedule around the most acute phase. For ablative treatments, the first five to seven days are the most visibly intense. Patients who need to be in public or on camera should plan accordingly.
| Treatment Type | Downtime | Results Timeline | Best For |
|---|---|---|---|
| Full ablative CO2 | 10 to 14 days | Visible in 2 to 4 weeks, full results at 3 to 6 months | Deep lines, significant sun damage, acne scarring |
| Fractional ablative CO2 | 5 to 7 days | 4 to 8 weeks, improves over 3 months | Moderate lines, texture, early scarring |
| Erbium YAG (ablative) | 5 to 10 days | 3 to 6 weeks | Moderate sun damage, fine lines, sensitive skin |
| Fractional non-ablative | 1 to 2 days | After 3 to 6 sessions, gradual over months | Mild texture, maintenance, darker skin tones |
Combining Laser Resurfacing with Other Treatments
Laser resurfacing addresses skin quality but does not correct volume loss or anatomical changes that come with aging. Many patients who undergo resurfacing also benefit from complementary treatments, either performed at the same time or staged separately.
Common combinations include:
- Laser resurfacing with fillers: Resurfacing improves surface quality and texture; fillers restore volume to areas like the cheeks, temples, and under the eyes. These can often be performed in the same appointment.
- Laser resurfacing with a facelift or brow lift: Surgical procedures correct structural changes in the face. Resurfacing treats the skin surface. When combined, the result addresses both anatomy and texture, which neither procedure alone can do as completely.
- Laser resurfacing with fat transfer: For patients who prefer a natural approach to volume restoration, fat transfer and resurfacing can be performed together during a single surgical session.
How Results Are Maintained
Laser resurfacing is not permanent in the sense that aging continues after treatment. Ablative CO2 results can last several years with good sun protection and skincare habits. Most patients return for maintenance treatment every one to three years to sustain their results.
Non-ablative treatment series are often repeated annually as part of an ongoing skin health program. These maintenance protocols can extend the results of a prior ablative treatment or address new changes as they develop.
The most predictable long-term results come from patients who take sun protection seriously. UV exposure is the single largest driver of skin aging and will undermine the results of any resurfacing treatment faster than anything else.
