What Is Fraxel Laser?
Last reviewed: May 2026 · Haute MD Editorial Team
Fraxel is a brand of fractional laser that resurfaces the skin by delivering thousands of microscopic laser columns into the skin, leaving surrounding tissue intact to accelerate healing. It is used to treat acne scars, sun damage, age spots, fine lines, wrinkles, surgical scars, and uneven skin tone. Fraxel DUAL treats the superficial layers; Fraxel REPAIR (CO2) penetrates deeper for more aggressive resurfacing.
Fraxel vs. CO2 laser
Fraxel DUAL uses non-ablative fractional technology — it treats the dermis without removing the epidermis. CO2 Fraxel (Fraxel REPAIR) is ablative and removes the outer skin layer for more dramatic results with longer downtime. Most patients seeking treatment for acne scars and tone begin with Fraxel DUAL.
What to expect
Topical anesthesia is applied 60-90 minutes before the procedure. During treatment you will feel heat and prickling. Afterword, skin appears swollen and red, similar to a significant sunburn. Peeling occurs over 3-5 days. Most patients return to normal activities within 5-7 days of Fraxel DUAL.
How many Fraxel treatments are needed?
Most conditions require 3-5 sessions of Fraxel DUAL spaced 4-6 weeks apart. A single Fraxel REPAIR session can achieve similar results with more downtime.
Frequently Asked Questions
Is Fraxel safe for darker skin tones?
Non-ablative Fraxel (DUAL) is generally safe for Fitzpatrick skin types I-IV with appropriate settings. Ablative CO2 laser carries higher risk of post-inflammatory hyperpigmentation in darker skin tones and requires an experienced provider.
How long do Fraxel results last?
Results from Fraxel — particularly for acne scars and sun damage — are long-lasting. New collagen produced during healing is permanent. Sun protection is essential to maintain results.
What is the difference between Fraxel and IPL?
Fraxel is a laser that resurfaces skin and stimulates collagen. IPL uses broad-spectrum light to target pigment and blood vessels. Fraxel is more powerful for skin resurfacing and scarring; IPL is better for diffuse pigmentation and redness.
What is the downtime for Fraxel?
Fraxel DUAL: 5-7 days of redness and peeling. Fraxel REPAIR (CO2): 7-14 days of more significant peeling and swelling.
