Laser Skin Resurfacing — Everything You Need to Know

Last updated: 5 March 2026

What Is Laser Skin Resurfacing?

Laser skin resurfacing is one of the most effective and well-established treatments in aesthetic dermatology. Using concentrated beams of light energy, the procedure removes damaged outer layers of skin with remarkable precision, stimulating the body’s natural healing response to produce fresh, smoother, more youthful-looking skin.

At Axiom Aesthetics on Harley Street, London, we offer a range of laser resurfacing options tailored to different skin concerns, skin types, and lifestyle requirements. This guide covers everything you need to know — from how lasers work to what your recovery will look like.

How Does Laser Skin Resurfacing Work?

All laser skin resurfacing treatments work on the same fundamental principle: controlled thermal injury. The laser delivers precise energy to the skin, which either removes thin layers of tissue (ablative) or creates microscopic zones of damage within the skin (fractional), triggering the body’s wound-healing cascade. This process stimulates the production of new collagen and elastin, resulting in tighter, smoother, more evenly toned skin.

Types of Laser Skin Resurfacing

1. Ablative Lasers

Ablative lasers physically vaporise the outer layers of damaged skin. They are the most aggressive form of laser resurfacing and deliver the most dramatic results, but also require the longest recovery time.

• CO2 (Carbon Dioxide) Laser — The gold standard of ablative lasers. Exceptionally effective for deep wrinkles, significant sun damage, scars, and skin laxity. Produces dramatic results but requires 1–2 weeks of downtime.
• Er:YAG (Erbium) Laser — A gentler ablative option that targets the surface more precisely with less thermal damage to surrounding tissue. Better suited for fine lines and superficial imperfections, with a shorter recovery period.

2. Non-Ablative Lasers

Non-ablative lasers heat the deeper layers of skin without removing the surface. They stimulate collagen production from within whilst leaving the outer skin intact, resulting in significantly less downtime.

• Nd:YAG Laser — Penetrates deeply and is safe for darker skin tones. Effective for skin tightening and vascular lesions.
• Pulsed Dye Laser (PDL) — Targets blood vessels, making it excellent for rosacea, broken capillaries, and red scars.
• Diode Lasers — Versatile systems used for skin rejuvenation, hair removal, and vascular treatments.

3. Fractional Lasers

Fractional technology — available in both ablative and non-ablative versions — has revolutionised laser resurfacing. Rather than treating the entire skin surface, fractional lasers create thousands of microscopic treatment zones, leaving healthy skin between them. This dramatically speeds up healing whilst still delivering impressive results.

• Fractional CO2 — Combines the power of CO2 with fractional delivery. Excellent results with shorter downtime than traditional CO2.
• Fraxel (Fractional Erbium) — One of the most popular fractional lasers worldwide. Available in non-ablative (Fraxel Dual) and ablative (Fraxel Repair) versions.

What Can Laser Resurfacing Treat?

Laser skin resurfacing can address an impressive range of skin concerns:

• Fine lines and wrinkles — Particularly around the eyes, mouth, and forehead
• Sun damage and photoageing — Including age spots, sun spots, and uneven pigmentation
• Acne scars — Both ice-pick and rolling scars can be significantly improved
• Surgical or traumatic scars — Improving texture, colour, and flatness
• Uneven skin tone and texture — Creating a smoother, more refined complexion
• Enlarged pores — Tightening and minimising pore size
• Skin laxity — Mild-to-moderate tightening through collagen stimulation
• Melasma — Certain lasers can help manage this challenging pigmentation condition
• Warts and skin lesions — Precise removal of benign skin growths

Choosing the Right Laser for Your Skin

The “best” laser doesn’t exist — the best laser is the one that’s right for your specific concerns, skin type, and lifestyle. Here’s a general guide:

• Deep wrinkles, significant scarring, or major sun damage: Ablative or fractional CO2
• Fine lines and mild textural concerns: Fractional erbium or non-ablative laser
• Pigmentation and uneven tone: Fractional erbium, IPL, or Q-switched laser
• Redness, rosacea, or broken capillaries: Pulsed dye laser or IPL
• Darker skin tones (Fitzpatrick IV–VI): Nd:YAG or carefully calibrated fractional lasers (many lasers carry higher risk of post-inflammatory hyperpigmentation in darker skin)
• Minimal downtime required: Non-ablative fractional or IPL

An experienced practitioner will assess your skin during consultation and recommend the most appropriate technology for your individual needs.

The Treatment Experience

Before Treatment

• Avoid sun exposure and tanning for 4–6 weeks before treatment
• Discontinue retinoids 7–14 days prior (as advised by your practitioner)
• You may be prescribed a skin preparation regimen (e.g., hydroquinone for pigmentation concerns)
• Inform your practitioner of any cold sore history — antiviral medication may be prescribed prophylactically
• Avoid blood-thinning supplements for one week prior

During Treatment

Depending on the type and intensity of the laser, treatment takes 30–90 minutes. Numbing cream, local anaesthesia, or in some cases sedation may be used for comfort. You’ll wear protective eye shields throughout.

Most patients describe the sensation as a warm, prickling feeling — often compared to an elastic band snapping against the skin. Advanced cooling systems built into modern lasers help manage discomfort during the procedure.

Immediately After Treatment

Your skin will appear red, warm, and slightly swollen — similar to a sunburn. With ablative treatments, there may also be some oozing and crusting in the first few days. Your practitioner will apply a soothing ointment and provide detailed aftercare instructions.

Recovery and Downtime: What to Realistically Expect

Non-Ablative Laser Recovery

• Days 1–2: Mild redness and warmth
• Days 3–5: Redness fades; minor flaking possible
• Return to normal activities: Same day or next day
• Makeup: Usually fine after 24 hours

Fractional Laser Recovery

• Days 1–3: Redness, swelling, and a rough, sandpaper-like texture
• Days 4–7: Peeling and flaking as the treated micro-zones heal
• Days 7–14: Redness gradually resolves; new, fresh skin emerges
• Return to normal activities: 5–7 days for most patients
• Makeup: Usually fine after 5–7 days once peeling resolves

Ablative Laser Recovery

• Days 1–5: Significant redness, swelling, oozing, and crusting
• Days 5–10: Crusting resolves; skin appears very pink and raw
• Weeks 2–4: Pinkness gradually fades
• Months 1–3: Residual pinkness resolves completely
• Return to normal activities: 10–14 days for most patients

Aftercare: Essential Steps for Optimal Results

Proper aftercare is crucial for both results and safety. Following your practitioner’s specific instructions is paramount, but general aftercare guidelines include:

• Keep the area clean — Gentle cleansing with a mild, pH-balanced cleanser
• Moisturise frequently — Apply the recommended healing ointment or gentle moisturiser as directed
• Sun protection is non-negotiable — SPF 50 broad-spectrum sunscreen daily for a minimum of 3 months. Sun exposure can cause permanent hyperpigmentation on newly resurfaced skin.
• Do not pick or peel — Allow the skin to shed naturally; premature removal can cause scarring
• Avoid active ingredients — No retinoids, AHAs, BHAs, or vitamin C for 2–4 weeks (or as directed)
• Stay hydrated — Drink plenty of water to support the healing process
• Avoid swimming pools, saunas, and steam rooms — For at least 2 weeks post-treatment
• No strenuous exercise — For 3–7 days depending on the treatment intensity

Results: What Can You Realistically Expect?

Laser skin resurfacing delivers some of the most impressive results in non-surgical aesthetics:

• Fine lines: 50–80% improvement with ablative/fractional treatments
• Acne scarring: 30–70% improvement per session (multiple sessions often recommended)
• Pigmentation: Significant reduction in sun spots and uneven tone
• Skin texture: Noticeably smoother, more refined surface
• Overall appearance: Fresher, more youthful, more radiant skin

Results continue to improve for 3–6 months after treatment as collagen remodelling progresses. With proper skincare and sun protection, results can last for years.

Risks and Potential Complications

As with any medical procedure, laser resurfacing carries some risks:

• Prolonged redness — More common with aggressive treatments; usually temporary
• Hyperpigmentation — Darkening of the skin, more common in darker skin tones; usually temporary but can persist
• Hypopigmentation — Lightening of the skin; rare but can be permanent
• Scarring — Very rare with proper technique and aftercare
• Infection — Including bacterial, viral (herpes simplex reactivation), and fungal
• Delayed healing — Particularly in smokers or those with certain medical conditions
