A Rejuvenating treatment targeting "tech neck" lines and wrinkles in Chinese women: A prospective, open-label, single-center study.

Background: Aging of neck and jawline skin is caused by intrinsic and extrinsic factors and is evidenced by wrinkling, laxity, skin dyspigmentation, loss of the mandibular contour, accumulation of submental fat, density loss, and prominent platysma bands. Early intervention with topical cosmeceuticals, especially in younger subjects with "tech neck," can offer a solution and potentially mitigate aging of the neck and jawline.

Aim: The objective of this prospective, open-label, single-center clinical study was to assess the efficacy and tolerability of a topical anti-aging neck treatment (TNT) in a cohort of Chinese women with mild to moderate signs of aging on the neck and jawline.

Subjects/methods: This study was approved by an ethics committee and involved healthy Chinese subjects. Thirty-five female subjects, 25-50 years old, with mild to moderate signs of aging of the neck and jawline were recruited. Subjects applied the TNT to the neck and jawline twice daily for 84 days. Long-term efficacy and tolerability, clinical photography, bioinstrumentation, and a self-assessment questionnaire were performed at baseline and post-baseline.

Results: The TNT significantly improved horizontal neck fold lines and neck skin elasticity, hydration, gloss/radiance, and skin tone evenness post-baseline. Clinical photography and ultrasound corroborated these findings. The product was well perceived and well tolerated by subjects.

Conclusion: This study demonstrated the TNT was effective against both extrinsic and intrinsic aging of the neck and jawline. The TNT provides a topical solution for Chinese women concerned with an aging appearance of the neck including "tech neck."
