Fraxel laser for skin without scars, spots, or stretch marks.

The Fraxel laser uses two specific wavelengths depending on the issue to address: the 1,555 nm for deeper concerns such as scarring and the 1,927 nm for superficial imperfections, such as pigmented spots.

• The Fraxel 1555 nm laser is effective against deep scars and wrinkles.

  The 1555 nm laser penetrates the dermis, reaching about 1.4 mm below the skin’s surface to eliminate deeper concerns such as acne scars, stretch marks, deep wrinkles and improvement of skin texture by stimulating production of collagen and elastin.

  A study on five patients evaluated Fraxel laser efficacy on spots and scars. Before each session, a topical anesthetic containing 23% xylocaine (lidocaine) and 3% tetracaine was applied one hour before treatment to reduce discomfort. After anesthesia, a blue dye specific to the Fraxel laser was applied. This dye ensures laser activation only on treated skin. A 5% xylocaine ointment was then applied to reinforce the anesthetic effect.

  In one patient who underwent two treatments, we noted improvement two weeks after the second session: reduced fine lines and fewer melanocytes, which produce melanin. In two other patients who had three to five sessions, we observed a significant decrease in unwanted melanocyte pigmentation. The second patient also noted reduced periorbital lines. The fourth patient reported more uniform tone, firmer skin, and fewer lines. The final patient, with hypertrophic, hyperpigmented burn scars on the thigh, showed improvement: flattened scars and reduced pigmentation.

• The 1,927 nm Fraxel for hyperpigmentation spots.

  The 1,927 nm Fraxel laser addresses pigmentation issues, brown spots, and dull skin following intense UV exposure. It also evens skin texture by targeting the superficial epidermis at depths of 0.5 to 1 mm.

  A study included 27 patients aged 29 to 74, all with Fitzpatrick phototypes I to IV, who received two 1,927 nm non-ablative laser treatments in May and June 2022. Follow-up covered 96 % of patients at one month and 89 % at three months. No serious adverse events were reported. The results show a significant improvement in dyspigmentation as early as one month after treatment, with a notable decrease in spots, UV spots, and brown patches. At three months, brown spots remained significantly reduced, with a 9.9 % improvement in pigmentation on the left side of the face and a 7.5 % improvement on the right side.

Both wavelengths can be combined for treatment of superficial and deep skin layers. Three to five sessions are required based on the area treated. After each session, we recommend applying a broad-spectrum sunscreen. Avoid direct sun exposure for three months after the procedure.

The side effects of Fraxel laser treatment vary by treated area and wavelength used. Areas such as the neck, chest, or hands require more healing time than the face and are more prone to side effects.

With the Fraxel 1 150 nm, redness may appear after treatment, accompanied by swelling, skin dryness, or a stiff skin texture that can last 1 to 3 days. These effects resolve within 2 to 7 days. The Fraxel 1 927 nm, by contrast, causes mild redness lasting 1 to 2 days. Initial results appear after the first session, with optimal effect after 6 months. Treatment benefits may last up to 4 years, depending on lifestyle and post-treatment care.

This treatment is contraindicated in pregnant or breastfeeding individuals, as well as in those who have undergone isotretinoin-based therapy within the previous six months. All photosensitizing treatments should also be avoided, including certain anticancer drugs, antidepressants, and antiepileptics.
