The device allows for energy adjustment from 6 to 20mj, giving an estimated depth of 200micron. The density is adjustable between 20 and 50%, and the scanner width has the choices of 4, 6, 8, 10, and 12mm. The latter is particularly a huge advantage as it allows for a customised treatment in smaller areas, as well as targeting with precision and maximum impact smaller lesions, such as lentigos and flat seborrheic keratoses. Case 1 A 56 year-old woman with evidence of photodamage and dull, rough facial skin was treated with the Frax 1940 handpiece, using the following parameters: Energy of 10 mj, density of 35%, scanner width of 10mm, 4 passes over the entire face with 2 additional passes on the large individual lentigos using a 4mm scanner width, 50% density and 7mj fluence. The clinical endpoint is erythema and post care consisted of a light-based moisturizer regularly with strict sun protection. The downtime is around 4 to 5 days with erythema and darkening of the lentigos, and a total of 2 treatments were performed with significant improvement in pigment reduction, smoothening of the skin and the ‘glow’ described by the patient that continued for weeks post treatment. Case 2 A 46 year-old woman with Fitzpatrick Skin Type 2 and evidence of photodamage, as well as what she described as a ‘dull and lifeless facial skin’ underwent a Figure 2 Case 2: (A) Before, (B) after treatment References 1.

Immediately post treatment topical vitamin C serum and non-cross-linked hyaluronic acid serum was applied to the skin. Downtime was 5 days of erythema with darkening of the superficial pigmented lesions. One month post treatment the patient reported significant improvement in the ‘feel of the skin’, texture and marked reduction in signs of photodamage. She particularly explained that her make-up simply sits much nicer on the skin and her facial skin is radiant with a glow.  Findoutmore at: candelamedical.com
