How Cool Laser Treatment Targets Skin Concerns with Precision

Introduction: The Science Behind Cool Laser Treatment

Cool Laser resurfacing is a doctor-led Er:YAG laser treatment that renews the skin safely across all types, from I to VI. At Riverbanks Clinic in Harpenden, we use this cutting-edge solution to treat pigmentation, scarring, texture concerns, and signs of ageing—without the intense side effects or extended downtime associated with the CO2 laser.

This Er:YAG laser treatment emits energy at 2940 nm, allowing for highly precise removal of skin layers with minimal thermal damage. The laser reaches a depth of 200–300 microns (0.2–0.3 mm)—making it perfect for superficial to medium-depth resurfacing with swift healing.

Six Key Benefits of Cool Laser Treatment

• Suitable for all skin types, including Fitzpatrick I–VI
• Uses a non-ablative skin laser setting for reduced downtime
• Customisable power to treat anything from fine lines to deep scars
• Delivers long-term skin laser rejuvenation
• Encourages collagen production without injectables
• Offered in a doctor-led, award-winning clinical environment

OVERVIEW

Cool Laser treatment is a form of fractional laser resurfacing that gently ablates damaged skin layers. It stimulates fresh collagen production while targeting pigmentation, scars, and laxity. It’s safe, effective, and customisable—even for laser treatment for all skin types.

How It Works at Different Strengths

Cool Laser is more than a single setting. It’s a personalised protocol, adjusted to match your concerns, skin tone, and downtime preference.

1. Light Strength: Gentle Laser Skin Resurfacing

• Targets: Dullness, fine lines, mild pigmentation
• Penetration: Superficial epidermis
• Mechanism: Gently ablates the topmost skin layers
• Downtime: 24 hours of mild redness or swelling
• Synonym used: gentle laser skin resurfacing
• Delivered by medical aestheticians

This is your go-to advanced laser facial if you’re prepping for a special event or want a quick glow-up without recovery time.

2. Medium Strength: Fractional Renewal

• Targets: Moderate wrinkles, uneven tone, sun damage
• Penetration: Up to 300 microns into the papillary dermis
• Mechanism: Fractional ablation stimulates natural repair processes
• Downtime: 2–3 days of redness and flaking
• Doctors and aestheticians: depending on indication. Eyes are doctors only.

This is the ideal option for patients seeking visible results through skin laser rejuvenation—without the commitment of longer downtime.

3. Strong Strength: Deep Remodelling

• Targets: Deep acne scars, coarse wrinkles, dermal pigmentation
• Penetration: Maximal safe depth for Er:YAG per pulse
• Mechanism: Aggressive collagen stimulation and tissue smoothing
• Downtime: 5–7 days of redness, peeling, swelling
• Doctors only: for eyes, around the mouth, stronger treatments

This is our most powerful Er:YAG ablative skin laser protocol, reserved for dramatic rejuvenation where results matter more than downtime.

Conditions Treated with Cool Laser

• Acne scars
• Age spots and sun damage
• Fine lines and wrinkles
• Uneven skin tone
• Melasma and other pigmentation disorders
• Enlarged pores
• Lax skin (especially around eyes and mouth)
• Textural roughness

It’s one of the few treatments proven safe and effective as a laser for pigmentation and scars, across all skin colours.

Safe for Fitzpatrick I–VI Skin

Unlike CO₂ systems, Er:YAG lasers are absorbed by water, not melanin. This makes Cool Laser a trusted laser treatment for all skin types, especially patients with darker skin who are more prone to pigmentation issues. We adjust the energy, density, and pass depth based on your individual tone and sensitivity.

What Happens During Cool Laser Treatment?

• Your skin is cleaned and numbed using medical-grade anaesthetic cream if required (30 mins)
• The Er:YAG laser treatment begins with pulses over the targeted areas
• You’ll feel a warm sensation—more comfortable than traditional ablative lasers
• The treatment typically lasts 20–40 minutes
• Post-procedure, a calming serum is applied and you’re free to go

We often recommend pairing this with Omnilux LED light therapy or Alastin Skin Nectar to boost healing.

Recovery and Downtime

How Long Do Results Last?

Cool Laser boosts collagen production that continues for months. While skin laser rejuvenation effects are visible within days, the biggest changes appear over 6–12 weeks. For deeper concerns like acne scars, 3–4 sessions are typically recommended.

Results can last 1–2 years with good homecare, medical-grade skincare, and occasional top-ups.
