Laser Treatments Demystified: Which Device Works Best for Pigmentation, Acne & Anti-Aging?

Laser treatments have transformed dermatology, offering non-surgical solutions for pigmentation, acne scars, wrinkles, and more. But with dozens of devices on the market—Fraxel, CO2, PicoSure, Halo, IPL—how do you know which one is right for your skin?

Chapter 1: How Lasers Work (The Science Simplified)

1.1 The Basic Principle

Lasers deliver focused light energy to target:

• Pigment (melanin) → Fades dark spots

• Collagen layers → Stimulates anti-aging

• Oil glands → Reduces acne

1.2 Wavelengths Matter

• Ablative lasers (CO2, Erbium) → Remove outer skin layers

• Non-ablative lasers (Fraxel, Pico) → Work beneath the surface

• IPL (not a true laser) → Broad-spectrum light for superficial issues

Chapter 2: Best Lasers for Pigmentation (Melasma, Sun Spots, PIH)

• Downtime: 1-2 days redness

Real Patient Result: 70% improvement in melasma after 3 sessions

2.2 Q-Switched Nd:YAG (For Deep Pigmentation)

• Targets: Tattoos, age spots, freckles
