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.

Time effect of facial and neck wrinkles (Dermatologist-assessed)
Clinical scoring of dynamic wrinkles in five facial and neck areas: forehead wrinkles (raising eyebrow), crow's feet wrinkles, underneath eye wrinkles, nasolabial folds (smiling), and horizontal neck folds (lowering head), as assessed by dermatologist at T0, T4wk, and T8wk using the Skin Aging Atlas. Assessment is based on facial expression photos and in-person evaluation. Wilcoxon Signed Rank Test will be used to analyze changes from baseline.
Time frame: Baseline (T0) to Week 8 (T8wk)
Time effect of facial wrinkles (Expression image-based)
Dermatologist-assessed wrinkle severity based on a series of 10 expression photos captured at baseline, week 4, and week 8. Areas include forehead wrinkles (raising eyebrow), crow's feet wrinkles, underneath eye wrinkles, nasolabial folds (smiling), and horizontal neck folds (lowering head). Images were taken using DEEP 1.0 and iPhone 15 Pro Max, and graded with the Skin Aging Atlas without referencing prior scores. Statistical analysis used Wilcoxon Signed Rank Test.
Time frame: Baseline (T0) to Week 8 (T8wk)
Time effect of adverse events and intolerance reactions
Any reported adverse events (AEs) and local intolerance reactions collected through participant diaries and on-site monitoring at each visit (T0, T4wk, T8wk). All events evaluated for severity, duration, and relation to the test product, and reported within 24 hours per protocol guidelines.
Time frame: Baseline (T0) to Week 8 (T8wk)
Time effect of product compliance (Twice-daily usage)
Participant adherence to the instructed regimen of twice-daily application of the investigational cream, assessed by product weight tracking and daily log review at week 4 and week 8 visits.
Time frame: Baseline (T0) to Week 8 (T8wk)
