A novel method to measure conspicuous facial pores using computer analysis of digital‐camera‐captured images: the effect of glycolic acid chemical peeling

Background/purpose: Chemical peeling is becoming increasingly popular for skin rejuvenation in dermatological esthetic surgery. Conspicuous facial pores are one of the most frequently encountered skin problems in women of all ages. This study was performed to analyze the effectiveness of reducing conspicuous facial pores using glycolic acid chemical peeling (GACP) based on a novel computer analysis of digital‐camera‐captured images. Methods: GACP was performed a total of five times at 2‐week intervals in 22 healthy women. Computerized image analysis of conspicuous, open, and darkened facial pores was performed using the Robo Skin Analyzer CS 50. Results: The number of conspicuous facial pores decreased significantly in 19 (86%) of the 22 subjects, with a mean improvement rate of 34.6%. The number of open pores decreased significantly in 16 (72%) of the subjects, with a mean improvement rate of 11.0%. The number of darkened pores decreased significantly in 18 (81%) of the subjects, with a mean improvement rate of 34.3%. Conclusion: GACP significantly reduces the number of conspicuous facial pores. The Robo Skin Analyzer CS 50 is useful for the quantification and analysis of ‘pore enlargement’, a subtle finding in dermatological esthetic surgery.
