Objectives: To determine the respective weights of certain facial signs on the assessment of the perceived age and a tired-look on Korean men of different ages.
Material And Methods: Photographs were taken of the faces of 101 Korean men (20-80 years) under standardized conditions. These photographs allowed to define 16 signs, which were then graded by 15 experts/dermatologists, using standardized scales provided by a referential Skin Aging Atlas. These signs were dispatched into 5 clusters, namely Wrinkles/Texture, Ptosis/Sagging, Cheek pores, Pigmentation, and Vascular signs. A naïve panel of 200 Korean individuals (100 women, 100 men), of similar age range, were asked, when viewing full-face photographs, to (a) attribute on a 0-10 scale their perception of a tired-look and (b) estimate the age of the subject.
Results: The severity of all clusters increased with age, although at different rates. The Wrinkles/Texture or Ptosis/Sagging showed a rather regular progression, whereas Vascular presented the weakest changes. Although perceived and real ages were found highly correlated, almost 85% of the subjects were judged older by 1-15 years. The signs/clusters were found significantly correlated with perceived age, highly for Wrinkles/Texture and Ptosis/Sagging, moderate for Pigmentation, and low for Vascular and Cheek pores. The weights in perceived ages of Wrinkles/Texture and Ptosis/Sagging represent 81% and Pigmentation at 19%. Facial tired-look of Korean men was found significantly correlated with perceived age. Although Vascular and Cheek pores were found not impacting, Wrinkles/Texture, Ptosis/Sagging, and Pigmentation presented a clear influence.
Conclusion: Within facial clusters, Wrinkles/Texture, Ptosis/Sagging, and Pigmentation are major factors in the assessment of perceived age in Korean men. The perception of an increased tired-look is significantly associated with increased perceived age.

Objective: To evaluate the capacity of the automatic detection system to accurately grade, from selfie pictures, the severity of eight facial signs in South African men.
Methods: Selfie pictures (obtained from frontal and back cameras) of 281 South African men differently aged (20-70 years) were obtained and analyzed by an automatic artificial intelligence (AI)-based automatic grading system. Data were compared with the clinical gradings made by experts and dermatologists.

Objective: To evaluate the capacity of the automatic detection system to accurately grade, from smartphones' selfie pictures, the severity of ten facial signs in Japanese women and their changes due to age and sun exposures.
Methods: A three-step approach was conducted, based on self-taken selfie images. At first, to check on 310 Japanese women (18-69 years) enrolled in the northerner Hokkaido area (latitude 43.

Objective: To determine the respective weights of certain facial signs on the assessment of perceived age and plumpness on Korean women of different ages.
Material And Methods: Photographs were taken of the faces of 112 Korean women of different ages (18-80 years) under standardized conditions. These photographs allowed to focus and define 19 facial signs, which were then graded by 15 experts and dermatologists, using standardized scales provided by a reference Skin Aging Atlas.

Background: New gratification assessments, after skincare routines or makeup products, could benefit from innovative methods that could predict the culturally based perceptions of age.
Aims: To determine the facial signs that most influence the perception of age in women of five different ethnic ancestries, assessed by the same ethnical naïve panel.
Patients/methods: The faces of 1351 women, differently aged (18-80 years), from five countries (China, France, India, Japan, and South Africa) were photographed under the same standardized conditions in the five countries.
