NCT03095872

Brief Summary

In the field of dermatology the healing process and therefore the success of a laser treatment are strongly determined by an appropriate postoperative treatment of the laser-treated skin. The manufacturer of CO2 laser systems recommends the application of Vaseline postoperatively to protect the treated tissue from air exposition until encrustation of the laser-treated skin decreases (usually after 7-14 days). An alternative to Vaseline could be Bepanthen® "Wund- und Heilsalbe" (Bayer). It contains the active ingredient pro-vitamin Dexapanthenol, which is widely used in dermatology therapy. The product helps to stabilize the protective barrier of the skin, to reduce the skin irritation, to stimulate the skin regeneration and to promote the wound healing. In an in-vitro study Bepanthen® "Wund- und Heilsalbe" triggered wound closure significantly faster compared to Vaseline. In this study the effect of Bepanthen® "Wund- und Heilsalbe" on wound healing should be investigated and compared to Vaseline in vivo following fractional ablative CO2 laser treatment of photo-damaged skin.

Outcome Measures

Primary Outcomes (4)

  • Change of the diameter of the individual lesions [initial value 1.3mm] between study visits.

    Large clinical digital photos as well as dermatoscopic images of the skin.

    Over 2 weeks (immediately after laser treatment and on day 1, 2, 5 and 14 after laser treatment)

  • Change of the size of the individual lesions between study visits.

    Two-dimensional microscopic skin cut images in real time of the skin.

    Over 2 weeks (immediately after laser treatment and on day 1, 2, 5 and 14 after laser treatment)

  • Visual changes of the wound healing between study visits.

    The wound healing rates will be visually assessed, based on the measure of re-epithelialization.

    Over 2 weeks (immediately after laser treatment and on day 1, 2, 5 and 14 after laser treatment)

  • Change of the wound under cosmetic aspects between study visits.

    The cosmetic result is based on a visual analog scale (VAS) from 0 (bad) to 10 (excellent, with no visible difference of the wound to the surrounding tissue).

    Over 2 weeks (immediately after laser treatment and on day 1, 2, 5 and 14 after laser treatment)

Secondary Outcomes (1)

  • Change of the transepidermal water loss (TEWL) between study visits.

    Over 2 weeks (immediately after laser treatment and on day 1, 2, 5 and 14 after laser treatment)

Study Arms (1)

Bepanthen/Vaseline

EXPERIMENTAL

One half of the wound occuring after CO2 laser therapy of photo-damaged skin is treated with Bepanthen and the other half with Vaseline.

Device: CO2-laserDrug: VaselineDrug: Bepanthen

Interventions

CO2-laserDEVICE

Patients with photo-damaged skin are treated with the CO2 laser to remove damaged skin layers.

Bepanthen/Vaseline

After the laser treatment, the wound area will be divided into two parts with a sterile skin marker. One area will be treated with Vaseline, and be marked "V". Thus, it is ensured that the care product will be applied correctly to the defined area. Postoperatively, this area of the wound will be treated with Vaseline. In the next seven days the patient will repeat the treatment every day at home.

Bepanthen/Vaseline

Thus, it is ensured that the care product will be applied correctly to the defined area. Postoperatively, this area of the wound will be treated with Bepanthen® Wund- und Heilsalbe. In the next seven days the patient will repeat the treatment every day at home.
