Dynamic Optical Coherence Tomography(D-OCT) Aging Study: A Preliminary Evaluation of Structural Differences Between Young and Aged Skin, Cellulite and Atrophic Acne Scars in Female Caucasian Subjects With Fitzpatrick Skin Types I-III Utilizing Non-invasive in Vivo D-OCT.

Study Overview
=================
Brief Summary
-----------------
This single-center clinical study is being conducted over the course of 2 weeks to conduct an exploratory pilot study as a preliminary evaluation of D-OCT's ability to measure skin changes from aging. Assess structural differences between young and aged skin on the face. To identify the structural characteristics of atrophic acne scars relative to normal skin on the face. To explore characteristics of cellulite relative to normal skin on the thigh in young and aged skin.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Group A - Young skin (18 - 30 years old)<br>Assessments will be made after facial cleansing on areas being imaged utilizing VivoSight Dynamic Optical Coherence Tomography (D-OCT). Post-study D-OCT images will be processed with VivoSight software. Assessments of participant's overall photodamage and participant's appearance of fine lines/wrinkles will be measured. | Device: Skin Imaging<br>* Non-invasive in vivo skin imaging will be taken with the VivoSight D-OCT and the measurements will be acquired post-study utilizing VivoSight software.<br>Other: Facial Cleanser<br>* Participants will be instructed to remove all makeup from the face and cleanse the face with SkinMedica Facial Cleanser at least 15 minutes prior to investigator assessments and photography, and at least 30 minutes prior to use of D-OCT. Particiapnts in the cellulite group will have the thigh area cleansed with Facial Cleanser at least 15 minutes prior to photography and at least 30 minutes prior to use of D-OCT. For standardization, this procedure will be performed with SkinMedica Facial Cleanser (to remove makeup and cleanse the face and thigh (if applicable)) for all the participants.<br>* Other names: SkinMedica® Facial Cleanser;|
| Group B - Aged skin (55 - 75 years old)<br>Assessments will be made after facial cleansing on areas being imaged utilizing VivoSight Dynamic Optical Coherence Tomography (D-OCT).
