Evaluation of a retinol containing topical treatment to improve signs of neck aging

The neck region is an area that can be indicative of signs of skin aging. A novel topical product that combines multiple active ingredients including retinol, tripeptide and glaucine was formulated to specifically target neck aging correction and complement post-procedure as part of an integrated skincare regimen. To evaluate the efficacy of a topical neck treatment through clinical subject evaluation, in addition to ultrasound and biopsy assessment. Evaluation for the efficacy of this novel topical product on improving the aging signs of neck skin was performed in multiple clinical trials. The first trial focused on clinical efficacy and included clinical assessment, subject questionnaires, ultrasound imaging and digital photographs. The second trial focused on biomarker analysis through skin biopsy. Data from the clinical trials showed that aging signs on the neck were significantly improved after 12 or 16 weeks of product usage. Changes were readily observed by clinical evaluators and participants. They were documented with digital photos, ultrasound images, and biomarker expression in the skin which clearly display the improvements. This novel topical product is effective in treating the aging signs on the neck skin and has been shown to provide statistically significant improvement on a myriad of neck aging attributes including fine lines/wrinkles, crepiness, laxity, and texture.
