What Laser Resurfacing Actually Does
Laser resurfacing is a cosmetic procedure that uses concentrated beams of light to improve the skin’s appearance and treat minor facial flaws. At its core, this technology creates a controlled injury to the skin. This process prompts the body’s natural healing mechanisms to kick in, stimulating the growth of new, healthy skin cells and boosting collagen production. Collagen is the protein responsible for your skin’s firmness and elasticity, which naturally declines with age.
Think of it as a precise, technology-driven way to “reset” your skin’s surface. By removing the outermost layer of damaged skin (epidermis) and heating the underlying layer (dermis), the procedure effectively diminishes the appearance of fine lines, wrinkles, acne scars, and uneven pigmentation. The result is skin that is smoother, firmer, and more even-toned. For a detailed overview of the procedure, you can refer to information from the Mayo Clinic.
How Different Laser Systems Work — Ablative vs. Non-Ablative vs. Fractional
Not all laser resurfacing treatments are the same. The technology can be broadly categorized into three main types, each with a different mechanism, intensity level, and recovery period. Understanding these differences is key to choosing the right treatment for your goals.
Ablative Lasers
Ablative lasers are the most intensive type. They work by vaporizing the thin outer layer of the skin (epidermis) and heating the underlying dermis. This stimulates significant collagen growth. Examples include the CO2 laser and the Erbium laser. While they produce the most dramatic results, especially for deep wrinkles and significant scarring, they also require the longest recovery time.
Non-Ablative Lasers
Non-ablative lasers are less invasive. Instead of removing the top layer of skin, they work by heating the tissue underneath the surface without harming the epidermis. This heat stimulates collagen production from the inside out. This approach results in a much shorter recovery time but typically requires multiple sessions to achieve desired results. It’s best suited for mild concerns like fine lines and minor texture issues.
Fractional Lasers
Fractional laser resurfacing is a modern approach that bridges the gap between ablative and non-ablative techniques. This laser delivers microscopic columns of energy deep into the skin, treating only a “fraction” of the tissue at a time. The surrounding untreated skin acts as a healing reservoir, dramatically speeding up recovery while still delivering impressive results. This technique, supported by extensive evidence-based reviews, can be either ablative or non-ablative and is highly effective for a range of concerns from wrinkles to scars.
Matching Technique to Concern: Scars, Wrinkles, Pigmentation
The success of a laser resurfacing treatment depends heavily on matching the right laser technology to your specific skin concern. A qualified dermatologist will help guide this decision, but here’s a general breakdown:
- Deep Wrinkles and Significant Sun Damage: Fully ablative lasers (like CO2) are often the gold standard. Their power to remove surface layers and trigger a major collagen response is highly effective for deep-set lines and extensive textural damage.
- Acne Scars (Atrophic/Indented): Fractional ablative lasers are a leading choice here. They can target deep into the dermis to break up scar tissue and stimulate new collagen to fill in the indentations, all with a more manageable recovery than fully ablative options.
- Fine Lines and Mild Texture Issues: Non-ablative fractional lasers are excellent for this. They offer noticeable improvement with minimal downtime, making them a great option for those who cannot afford a long recovery period.
- Pigmentation, Age Spots, and Melasma: A combination of non-ablative fractional lasers and other light-based treatments may be used. These lasers target the melanin (pigment) in the skin, breaking it up so the body can naturally clear it away. Treating pigmentation requires a highly skilled practitioner to avoid complications.
Skin Tone and Safety: Suitability, Testing, and Special Considerations
One of the most critical factors in laser resurfacing is skin tone. Individuals with darker skin tones (Fitzpatrick skin types IV-VI) have a higher concentration of melanin, which can absorb the laser energy more readily. This increases the risk of complications like post-inflammatory hyperpigmentation (PIH), where dark spots appear after treatment, or hypopigmentation (light spots).
However, this does not mean laser resurfacing is off-limits. It simply requires a more cautious and expert approach.
Key Considerations for Skin of Color:
- Choosing the Right Laser: Generally, non-ablative fractional lasers and lasers with longer wavelengths (like Nd:YAG lasers) are considered safer for darker skin, as they are less disruptive to the melanin in the epidermis.
- Practitioner Experience: It is absolutely essential to seek a board-certified dermatologist with extensive, demonstrable experience in performing laser resurfacing on skin of color. Do not hesitate to ask for before-and-after photos of patients with a similar skin tone to yours.
- Patch Testing: A provider should always perform a patch test on a small, discreet area of skin. This allows them to observe how your skin reacts to the laser settings before committing to treating a larger area.
- Pre-Treatment Regimen: Your doctor may prescribe a topical cream (like a retinoid or hydroquinone) for several weeks before the procedure to help suppress pigment production and reduce the risk of PIH.

Preparing to Minimize Complications: A 6-Week Checklist
Proper preparation is crucial for a safe procedure and smooth recovery. Follow your doctor’s specific instructions, which will likely include the following timeline:
6 Weeks Before Treatment
- Avoid Sun Exposure: Stop tanning and be diligent about applying a broad-spectrum SPF 30+ sunscreen daily. Tanned skin cannot be treated.
- Stop Certain Skincare Products: Discontinue the use of topical retinoids (like tretinoin) and strong exfoliants (like glycolic acid), as they can increase skin sensitivity.
2 Weeks Before Treatment
- Medication Review: Discuss all medications and supplements with your doctor. You may need to stop taking blood thinners like aspirin, ibuprofen, and vitamin E to reduce the risk of bleeding.
- Avoid Other Procedures: Do not get chemical peels, waxing, or collagen injections in the treatment area.
- Plan for Downtime: Arrange to take time off from work and social commitments. The length of time will depend on the type of laser used.
The Day Before Treatment
- Hydrate: Drink plenty of water.
- Arrange Transportation: You may receive medication that makes it unsafe for you to drive home.
- Get a Good Night’s Sleep: Rest is an important part of the body’s healing process.
The Procedure Step-by-Step: What Happens on the Day
Knowing what to expect on the day of your laser resurfacing can help ease any anxiety. The process is straightforward and typically follows these steps:
- Cleansing: Your face will be thoroughly cleansed to remove any oils, makeup, or bacteria from the skin’s surface.
- Anesthesia: Depending on the laser’s intensity and the size of the treatment area, your doctor will apply a topical numbing cream. For more intensive ablative treatments, a local anesthetic injection or even light sedation may be administered to ensure you are comfortable.
- Eye Protection: You will be given special protective eyewear to shield your eyes from the powerful laser light.
- The Treatment: The doctor will methodically move the laser handpiece over the targeted areas of your skin. You may feel a snapping or stinging sensation, often compared to a rubber band snapping against the skin. A cooling device may be used simultaneously to keep you comfortable. A full-face treatment can take anywhere from 30 minutes to two hours.
- Initial Post-Care: Once the procedure is complete, your doctor will apply a soothing ointment and dressing to the treated skin to protect it and keep it moist.
Recovery Timeline with Expectations for Days 1–90
Recovery varies significantly based on the type of laser used. The following table provides a general timeline for a fractional ablative laser treatment, one of the most common types. Non-ablative treatments will have a much shorter timeline, while fully ablative lasers will have a longer one. Always follow your provider’s specific aftercare instructions.
| Timeframe | What to Expect Visually | Sensations & Feelings | Key Care Instructions |
|---|---|---|---|
| Days 1–3 | Significant redness, swelling, and oozing (for ablative). Looks like a severe sunburn. | Feeling of intense sunburn, itching, tightness. | Cleanse gently as instructed, apply prescribed ointment frequently, use cool compresses, sleep with head elevated. |
| Days 4–7 | Peeling and flaking begin. Redness starts to subside into a pinkish hue. Swelling decreases. | Itching is common as skin heals. Skin feels very dry and tight. | Continue gentle cleansing and moisturizing. Do not pick or scrub the peeling skin. Avoid all sun exposure. |
| Week 2 (Days 8–14) | Most peeling is complete. Skin is pink and may appear blotchy. It will feel smooth but sensitive. | Sensitivity and dryness persist. | You may be cleared to wear mineral makeup. Meticulous sun protection is non-negotiable. |
| Month 1 (Days 15–30) | Pinkness continues to fade. The initial results of improved texture and tone become more apparent. | Skin may still feel slightly sensitive. | Continue a gentle skincare routine. Reintroduce other products only with your doctor’s approval. SPF 30+ is mandatory. |
| Months 2–3 (Days 60–90) | Redness should be mostly resolved. Collagen remodeling continues, and results will keep improving. | Skin should feel back to normal. | Maintain sun protection and a healthy skincare routine to protect your investment. |

At-Home Skincare and Supplements to Support Healing
Your actions at home are just as important as the procedure itself for achieving the best results from your laser resurfacing. The focus should be on gentle care, hydration, and protection.
Post-Treatment Skincare
- Gentle Cleanser: Use a mild, non-soap, fragrance-free cleanser with lukewarm water. Avoid washcloths or scrubbing.
- Healing Ointment/Moisturizer: In the initial days, you’ll use a thick, occlusive ointment provided by your doctor. Later, you’ll switch to a thick, bland moisturizer free of irritants like acids, retinoids, or fragrances.
- Sunscreen: This is the most crucial step. Once your skin has healed enough (as advised by your doctor), apply a broad-spectrum, physical (zinc oxide or titanium dioxide) sunscreen with an SPF of 30 or higher every single day, even if you are indoors.
Supportive Lifestyle and Supplements
- Hydration: Drink plenty of water to help your skin heal from the inside out.
- Diet: A diet rich in antioxidants, vitamins (especially Vitamin C), and protein can support tissue repair.
- Supplements: Some providers may suggest taking Vitamin C or other supplements to support collagen synthesis. Always consult your doctor before starting any new supplement regimen post-procedure.
Common Risks, How They’re Managed, and Red Flags
While laser resurfacing is safe when performed by a qualified professional, it’s important to be aware of the potential risks.
Common and Expected Side Effects:
- Redness, Swelling, and Itching: These are normal parts of the healing process and typically resolve within one to two weeks.
- Acne or Milia: Small white bumps can appear as the thick ointments used during healing can clog pores. These usually resolve on their own.
Potential Complications:
- Infection: Bacterial, viral (such as a reactivation of cold sores), or fungal infections are possible. Your doctor may prescribe an antiviral or antibiotic medication as a preventative measure.
- Changes in Skin Color: As mentioned, hyperpigmentation (darkening) or hypopigmentation (lightening) can occur, with a higher risk in darker skin tones. This risk is minimized by choosing an experienced provider and strictly adhering to sun protection.
- Scarring: Though rare, scarring is a potential risk. Following post-care instructions meticulously is the best way to prevent this.
Red Flags: When to Call Your Doctor
Contact your doctor immediately if you experience severe pain, increased swelling, pus or yellow crusting (a sign of infection), or blistering after the initial healing phase.
Non-Laser Alternatives and When to Consider Them
Laser resurfacing is a powerful tool, but it’s not the only option for skin rejuvenation. Depending on your specific concerns, goals, and acceptable downtime, you might consider these alternatives:
- Microneedling: This procedure uses fine needles to create micro-injuries in the skin, stimulating collagen production. It’s effective for texture, fine lines, and some scars, with less downtime than most lasers.
- Chemical Peels: A chemical solution is applied to the skin to exfoliate the outer layers. Peels range from superficial (mild) to deep (intensive) and can treat wrinkles, pigmentation, and acne.
- Radiofrequency (RF) Treatments: These use energy waves to heat the deep layers of the skin, tightening tissues and stimulating collagen with little to no downtime.
- Topical Retinoids: Prescription-strength creams like tretinoin can improve fine lines, texture, and pigmentation over several months of consistent use. This is a long-term, at-home approach rather than a one-time procedure.
Consider alternatives if your primary concern is skin laxity (RF might be better), if you have a skin type at very high risk for pigmentation changes, or if you simply cannot accommodate the downtime required for laser resurfacing.
Frequently Asked Questions and Myth Busting
Is laser resurfacing painful?
Discomfort is managed with topical or local anesthesia. Patients typically describe the sensation as a series of warm, sharp snaps. Post-procedure, it feels like a significant sunburn, which is managed with prescribed care.
How many treatments will I need?
For ablative lasers, one treatment often yields dramatic results. For non-ablative and fractional lasers, a series of 3-5 treatments spaced about a month apart is common to achieve optimal outcomes.
Myth: Laser resurfacing thins your skin.
Fact: This is a common misconception. While the procedure removes the very top layer of damaged skin, its primary function is to stimulate the production of new, thick, healthy collagen in the deeper dermal layer. Over the long term, this process actually leads to thicker, denser, and more resilient skin.
Myth: The results are permanent.
Fact: The results can be very long-lasting, often for many years. However, laser resurfacing does not stop the natural aging process. New wrinkles and spots will eventually form. Consistent sun protection and a good skincare routine are the best ways to maintain your results. Upcoming strategies from 2025 and beyond will likely focus on combination therapies to prolong these effects even further.
