Three-dimensional Quantification of Skin Surface Displacement Following Skin Rejuvenation Using Solar Protection and...

BACKGROUND: Common techniques, including photography and subjective assessments, have been used to measure the efficacy of skin rejuvenation treatments. However, the efficacy of skin treatments can be difficult to assess, particularly when the effects are gradual or subtle. OBJECTIVE: This study investigated the effectiveness of a skincare regimen for skin rejuvenation that employs comprehensive solar protection, ranging from ultraviolet through to near-infrared radiation, and nightly repair of photodamage, and clarified the difference in the results relative to other lifting medical procedures. METHODS: Twenty Japanese patients were enrolled in this study. The participants used topical skincare products (The Essential Six; RATIONALE, Victoria, Australia) for six months. Patients did not use any other skincare formulations and did not undergo any form of aesthetic procedures during the study. A superimposed three-dimensional volumetric assessment and quantification of three-dimensional skin surface displacement with vectors were performed at baseline and after six months of treatment with the topical skincare products. RESULTS: Improvements in skin texture and clarity as recorded via digital photography and volumetric reduction was observed relative to pretreatment in all patients. All patients self-reported skin rejuvenation, tightening, and lifting. Most vectors suggested three-dimensional skin surface displacement at the forehead, lateral sides of the cheek, and around the chin. CONCLUSION: Skin tightening and lifting effects are not synonymous. The results of this study suggest the solar-specfic skincare formulations evaluated here constitute a safe and effective means of skin rejuvenation and tightening.
