The purpose of this study is to obtain information (such as lesion depth, depth of the most superficial part of the lesion, and the size and density of blood vessels) with the assistance of an imaging device, and use this information to assist in selection of laser settings for the treatment of skin conditions. The imaging modality is called Optical Coherence Tomography (OCT). Multiple laser modalities will be used, including intense pulsed light lasers (BroadBand Light, Profractional Sciton), pulsed dye lasers (Vbeam Perfecta, Candela), long-pulse 755nm lasers (GentleLASE, Candela), Sciton long-pulse 1064nm lasers, and non-ablative and ablative fractional resurfacing lasers (Profractional, Sciton). All of the lasers noted above are the only ones that will be used in this study. These lasers have 510k clearance and are being used as per their approved indications in this study. The choice of laser type is based on the skin lesion and is recommended by the physician, and the subjects who are going to enroll in this study will already be planned to undergo laser treatment as a standard of care for their condition. This is a pilot study that will explore the utility of skin imaging in guiding the laser treatment of skin lesions.

Eligibility | Inclusion Criteria Subjects must meet the following inclusion criteria: - Ability to understand and carry out subject instructions or be represented by a legally authorized guardian or representative. - Ages 4 and older. Patients younger than 4 may have difficulty cooperating with the OCT measurements because each measurement requires the patient to remain still for approximately 30 seconds. - Seeks and is scheduled for laser treatment of a skin lesion. Exclusion Criteria Any of the following will exclude participation in the study: - Inability to understand and/or carry out subject instructions. |

---|---|---|---|---|
Other | Number of Participants With Scarring, Blistering, Bruising, and Scabbing | Any adverse effects of treatment such as scarring, blistering, bruising, and scabbing. | Through study completion; average of one year | |
Primary | Assessment of Change in Photographed Lesion | Primary outcome variable includes assessment of change in photographed lesion. Two board-certified dermatologists will grade the degree of change of the photographed lesion in quartiles (no change or darkening=0-25, mild lightening=26-50, good lightening=51-75, excellent lightening=76-95, complete resolution=96-100). | Through study completion; average of one year |
