The goal of this clinical trial is to find out whether a new cream (Formula# 899675 44A) can help reduce dynamic facial and neck wrinkles in young Chinese women. The main questions it aims to answer are:

• Does the cream lower the appearance of forehead wrinkles, crow's feet, under-eye wrinkles, and nasolabial folds when participants smile or raise their eyebrows?
• Does the cream help reduce horizontal neck folds when participants lower their heads?

About 45 healthy women between the ages of 18 and 35 will take part in this 10-week study. They will:

• Stop using other anti-aging products for 2 weeks (wash-out period)
• Apply the study cream on their face and neck twice a day for 8 weeks
• Visit the clinic 4 times for facial and neck photo collection and clinical assessments
• Learn to make standard facial expressions for photo comparisons

Researchers will compare wrinkle changes using dermatologist scores and photo grading at different time points.
