Brief summary
In this study, researchers want to learn more about the effect of dexpanthenol dermal spray on skin recovery and reduction of skin redness after a dermatological procedure (non-ablative laser) on the face for treatment of fine wrinkles, scars, open pores and change of pigmentation. After the dermatological procedure, participants will return within 3 weeks for 4 visits to the study center to investigate the skin conditions such redness, irritation, softness and possible side effects. In addition, study participants will be asked about their general acceptance of dexpanthenol dermal spray.
