Fraxel laser indications and long-term follow-up

Area of Science:

• Dermatology
• Aesthetic Medicine
• Laser Surgery

Background:

• Fractional photothermolysis is a laser technique creating microscopic thermal zones in the skin.
• A 1550-nm erbium fiber laser targets water in tissues for photocoagulation.
• This method aims for precise thermal wound creation with minimal collateral damage.

Purpose of the Study:

• To evaluate the safety and efficacy of Fraxel resurfacing.
• To assess its effectiveness for photodamage, scars, and dyspigmentation.
• To compare Fraxel outcomes with traditional ablative laser resurfacing.

Main Methods:

• Utilizing a 1550-nm erbium fiber laser for fractional photothermolysis.
• Treating microscopic thermal zones in a fraction of the skin per session.
• Administering a series of treatments (3-6 sessions) at 2-4 week intervals.

Main Results:

• Fraxel resurfacing demonstrated safety and effectiveness for photodamage, atrophic acne scars, hypopigmented scars, and dyspigmentation.
• A series of treatments yielded results comparable to ablative laser resurfacing for atrophic scars.
• Results for perioral laxity and rhytides were less impressive than those from ablative laser resurfacing.

Conclusions:

• Fractional photothermolysis with Fraxel is a viable option for specific skin conditions.
• Multiple treatment sessions are necessary for optimal clinical improvement.
• While effective for scars, Fraxel may not fully match ablative lasers for certain aging signs like wrinkles.
