This study is a single-center observational clinical study aimed at evaluating the impact of Cerave Neuroceramide Moisturizing Repair Body Lotion on the quality of life, improvement in skin condition, and satisfaction with the product experience among individuals with moderate to severe dry skin associated with aging. The study plans to recruit approximately 210 male or female participants aged 55 years or older with moderate to severe skin dryness in the affected areas (accounting for a dropout rate and protocol violation rate of no more than 5%), and will screen participants based on inclusion and exclusion criteria to ensure that at least 200 participants complete the study. Participants entering this study will be categorized based on ODS and NRS scores into: moderate or severe skin dryness (moderate-grade 2, severe-grade 3), with the sample size ratio between moderate and severe groups maintained at 1:1. This study will last for 4 weeks and include 2 visits. Visits will be conducted at baseline (T0) and week 4 (T4w). The window period for the week 4 (T4w) visit is ±2 days. This study does not involve randomization. All study participants will use Cerave Neuroceramide Moisturizing Repair Body Lotion on areas of skin dryness.
