Purpose: to known the potential of 8% purple sweet potato extract for wrinkles, moisture, and elasticity. Methods: A one-group experimental study with pre and post-test assessment. The subject is women with photoaging aged 30-45 years. A pre-test was conducted by examining wrinkles using the Glogau scale and a simple A-one scanner, treatment with 8% purple sweet potato extract cream for 6 weeks, and then a post-test at the end of the 6th week to check wrinkles, moisture, and elasticity using a simple A-one scan. Statistical tests using the SPSS program, version 25.0. The analysis performed was descriptive statistical and comparative analysis using a paired T test.  Result: A total of 25 respondents with a mean age ± SD of 38.22 ± 4.23 years, the most Glogau scale in type 2 is 22 respondents (88%), the most sun exposure for 30 minutes per day is 14 respondents (56%). The degree of wrinkles decreased after treatment -4.960±1.353 [95% CI -7.681-(-2.239); P=0.001]. The degree of moisture increased after treatment 8.840±2.990% (95% CI 2.829-14.851; P=0.005. The degree of elasticity increased after treatment 14.840±4.623 (95% CI 5.544-24.136; P=0.002). Conclusion: 8% purple sweet potato extract can reduce the degree of wrinkles, improve the degree of skin moisture, and improve the degree of skin elasticity.
