Abstract
This study aimed to assess the human efficacy of an eye cream formulated with Lavandula angustifolia(lavender)flower extract,dipeptide-4,ascorbyl tetraisopalmitate,Boswellia serrata resin extract,glucosyl hesperidin,tocopheryl nicotinate,bacillus ferment and caffeine for treating early aging symptoms around the eyes.A total of 31 Chinese women aged 27 to 45 years with noticeable dark circles,periorbital wrinkles,and eye bags participated in the study.They applied the eye cream around the eyes twice daily for four weeks.Evaluation of periorbital skin before and after product usage was conducted through non-invasive instrumentation,dermatologist assessment,and subject self-assessment.The results show that partial use of eye cream can significantly brighten skin color,and improve dark circles,eye bags,and fine lines.After 2 weeks of use,there is a significant improvement in the melanin index,erythema index,skin color,eye bag volume,and periorbital wrinkle parameters,which continue to improve up to 4 weeks.It is worth noting that the subjective evaluations by dermatologists and volunteers show good correlation and consistency with the instrument data.This study presents a comprehensive evaluation method based on quantitative instrument measurements and subjective assessments,providing valuable insights for developing eye area skincare formulations.关键词
