Fraxel is a brand of non-ablative fractional laser from Solta Medical, best known in its dual-wavelength form combining 1550 nm and 1927 nm. By creating microscopic zones of heat in the skin while leaving the surface intact, it prompts the skin's own repair and collagen renewal, and is a classic choice for texture, pigmentation, and fine lines.
Fraxel is most often discussed for photoaged skin: rough or uneven texture, fine lines around the eyes and mouth, sun-induced spots and mottled tone, enlarged-looking pores, and acne scars. The two wavelengths divide the work—1550 nm reaches deeper to address texture, fine lines, and scarring, while 1927 nm works more superficially on pigmentation and overall tone. Commonly treated areas include the face, neck, chest, and the backs of the hands.
It improves the quality of the skin's surface and stimulates gradual collagen remodeling, but it is not a lifting procedure: it does not reposition sagging tissue the way surgery does, nor does it tighten deeper layers the way ultrasound- or radiofrequency-based devices aim to. It also differs from ablative fractional lasers, which vaporize tissue for stronger single-session change at the cost of a longer recovery; non-ablative Fraxel trades intensity for a milder, repeatable approach.
The underlying principle is fractional photothermolysis: instead of heating the whole surface, the laser places thousands of microscopic columns of thermal injury into the skin, each surrounded by untouched tissue. Because the surface stays unbroken and healthy skin sits right next to every treated column, healing is comparatively fast. Over the following weeks, the body clears the damaged cells—carrying pigment out with them—and lays down new collagen where the columns were.
At the visit, the skin is cleansed and a topical numbing cream is usually applied and left to take effect, often for close to an hour. The handpiece is then glided across the area in several passes, typically with cooling air; most people describe a hot, prickling sensation. Immediately afterward the skin feels sunburned and looks red or swollen; over the next days it often takes on a bronzed, sandpaper-like quality before flaking off. Visible improvement builds gradually, and a series of sessions spaced weeks apart is common.
The typical candidate is an adult bothered by sun damage, uneven tone, fine lines, rough texture, or acne scarring, who accepts gradual improvement over a series of sessions and can plan around a few days of visible redness and flaking. A worthwhile consultation should cover which concern matters most to you, how your skin tone affects pigmentation risk, which wavelength and settings fit the goal, how many sessions are realistic, whether another technology matches the concern better, and how strictly you can commit to sun protection afterward.
It is not for everyone. Treatment is generally postponed during pregnancy and when there is an active skin infection in the area, including a cold-sore outbreak. Recent isotretinoin use, a history of keloids or abnormal scarring, and melasma all call for careful discussion, since heat can worsen pigment in some people. Deeper skin tones carry a higher risk of post-inflammatory pigment change and need an experienced assessment. Anyone expecting facelift-level tightening will likely be better served by a different approach.
Expected short-term effects include redness, swelling, warmth, and a sunburn-like sting for the first days, followed by dryness, a bronzed cast, and sandpaper-textured flaking that typically resolves within about a week on the face; off-face areas such as the neck, chest, and hands generally heal more slowly. Itching is common during the flaking phase. Strict sun protection and the provider's skincare instructions matter during this window, because fresh post-laser skin marks easily.
Less common problems include post-inflammatory hyperpigmentation—more likely with deeper skin tones or early sun exposure—reactivation of cold sores, acne or milia flares, blistering, prolonged redness, infection, and, rarely, scarring. Because this is a medical laser procedure, parameter choices and operator judgment directly affect these risks: it should be performed at a licensed medical institution by, or under the supervision of, a qualified physician, with the device's registration status confirmed through the provider.
Contact the treating clinician promptly if pain worsens instead of easing, the skin blisters, oozes, or crusts in a way that suggests infection, dark or light patches appear and spread, or a cold sore erupts after treatment.
