An Observational Clinical Study to Evaluate the Efficacy of the CeraVe Skin Care Line in Improving Mild to Severe Acne on the Face

This is an observational clinical study to evaluate the efficacy of the CeraVe Skin Care product line in improving mild to severe facial acne. Primary Objective: To evaluate the efficacy of CeraVe Skincare products in improving mild to severe facial acne through clinical observation by dermatologists of skin conditions before and after the use of the test product kit during the course of acne medication, as well as to collect concurrent feedback on the quality of life of this population and their experience with and satisfaction with the test product. Secondary objectives: 1. To collect feedback on the experience, satisfaction and quality of life improvement of CeraVe products through subjective evaluation of the subjects after using the products, in order to gain a deeper understanding of the comprehensive performance of the products in actual application; 2. To verify the tolerance of CeraVe products through clinical evaluation of the facial skin condition before and after the use of the products by dermatologists; 3. To evaluate the effectiveness of CeraVe products in improving acne. CeraVe is a dermatologist's clinical assessment of facial skin conditions before and after use to verify the tolerability and safety of CeraVe's skin care products. The study is designed to enroll approximately 240 male and female study participants aged 13 years or older with mild to severe facial acne, with a minimum sample size of 200 subjects based on a 15% dropout rate during the trial period and a protocol violation rate of no more than 5%. Participants entering the study will be classified as having mild, moderate, or severe acne according to the Global Evaluation Acne Grading Scale (GEA) (mild-grade 1 or grade 2, moderate-grade 3, severe-grade 4 or higher), with a sample size of mild acne:moderate acne:severe acne of approximately 1:1:1. The study was conducted over an 8-week period with 3 visits. They were conducted at the baseline visit (T0), week 4 follow-up (T4w) and week 8 follow-up (T8w). The window period was ±1 day for the week 4 (T4w) visit and ±2 days for the week 8 (T8w) visit. The primary evaluation parameters included: clinical assessment and product tolerance assessment by the dermatologist, patient self-assessment and questionnaires.

Outcome Measure	Measure Description	Time Frame
Changes in patients' GEA grading before and after use of the trial product kit	The Global Evaluation Acne Grading Scale (GEA) is a clinical tool used to assess the severity of acne.

A score of 1 indicates almost clean skin, almost no lesions, occasionally visible, scattered open or closed pimples, almost no papules. 2 indicates mildly recognizable, almost no papules. A score of 2 represents mildly recognizable acne involving no more than half of the face, with a few open or closed pimples, a few papules and pustules. A score of 3 represents moderate acne involving more than half of the face, with many open or closed pimples, numerous papules and pustules, and possibly a nodule. A score of 4 represents severe acne involving the entire face, with many open or closed pimples, numerous papules and pustules, and occasional nodules. A score of 5 represents highly inflammatory acne covering the entire face	Baseline visit, week 4 visit, week 8 visit
