Fraxel Laser Skin Resurfacing
Fraxel skin rejuvenation is a fractional laser treatment designed to improve skin texture, tone, and overall appearance by stimulating the body’s natural healing response. For patients seeking a non-surgical option to address sun damage, fine lines, acne scars, or uneven pigmentation, this technology offers measurable improvement with controlled downtime.
Dr. Richey is a board-certified dermatologist who has completed fellowships in both Mohs surgery and laser and cosmetic dermatology. She is a well-known laser expert with years of experience who completed her training at Harvard Medical School and the Wellman Center for Photomedicine, where Fraxel® laser, pulsed dye laser, cryolipolysis, laser hair removal and laser tattoo removal were invented.
Fraxel works by delivering microscopic columns of laser energy into the skin while leaving the surrounding tissue intact. This fractional approach is what allows the skin to heal more efficiently compared to older fully ablative laser resurfacing treatments. The laser creates controlled micro-injuries beneath the surface, which stimulate collagen production and accelerate cellular turnover. As new collagen forms and damaged skin cells are replaced, the skin gradually appears smoother, clearer, and more even in tone. The untreated portions of skin allow for rapid healing with no scarring and minimal downtime. Because only a fraction of the skin is treated in a single session, multiple treatments are often recommended to achieve optimal results.
Fraxel® laser treatment offers three primary categories of skin improvement through its dual wavelengths, allowing treatment to be customized based on your specific skin concerns.
Skin Texture
The 1550nm wavelength is designed to improve skin texture and stimulate collagen remodeling deeper within the skin. It is commonly used to soften fine lines and wrinkles, improve rough or uneven texture, reduce enlarged pores, and minimize the appearance of acne scars, surgical scars, and other skin irregularities. By resurfacing damaged skin and encouraging new collagen production, this wavelength helps create smoother, firmer, and healthier-looking skin over time.
Skin Tone
The 1927nm wavelength primarily targets pigmentation concerns closer to the skin’s surface. It is effective for reducing brown spots, sun damage, age spots, melasma, and uneven skin tone caused by years of UV exposure. This wavelength can help brighten the complexion and restore a more even skin tone, making it a popular option for patients seeking improvement in discoloration and visible signs of sun damage.
Skin Cancer
In addition to cosmetic benefits, emerging research has suggested broader skin health advantages. A recent study from Harvard Medical School demonstrated that regular Fraxel® laser treatments may help decrease the risk of certain skin cancers by treating sun-damaged skin and reducing precancerous cellular changes.
On the day of treatment, a topical numbing cream is typically applied to minimize discomfort. During the procedure, the handpiece is passed over the targeted area in controlled patterns. Patients often describe the sensation as a warm, prickling feeling. Treatment time depends on the size of the area being addressed but usually ranges from 20 to 45 minutes.
Expectations regarding skin improvement and post-procedure downtime will be discussed with you in detail prior to the treatment. For most patients, a series of monthly treatments are recommended, followed by maintenance treatments.
Immediately after treatment, the skin appears red and feels warm, similar to a moderate sunburn. Swelling can occur, particularly around the eyes, and usually peaks within the first 24 to 48 hours. Over the next several days, the skin may feel dry or rough as microscopic, treated areas exfoliate. Bronzing or darkening of pigmented spots can occur temporarily before they flake away.
Most patients resume normal daily activities within a few days, although strict sun protection is essential during healing. Gentle skincare products are recommended, and active ingredients such as retinoids are typically paused until the skin has recovered. Makeup can usually be applied after several days once redness subsides. The degree of downtime depends on the intensity of the treatment performed.
