Evaluating the respective weights of some facial signs on the perceived radiance/glow in differently aged women of six countries.

Objectives: To evaluate the impact of Facial radiance or Glow on the perception of age (PA) and to assess which facial signs most influence PA.

Material And Methods: The faces of 1058 differently aged women (18-80 years) of six different ethnicities/countries (China, Japan, Korea, India, South Africa, and Brazil) were photographed under standard conditions. These allowed to focus on 20 different facial signs that were further graded by experts, using referential Atlases dedicated to facial aging.

Skin moisture assessment using Hydration Sensor Patches coupled with smartphones via Near Field Communication (NFC). A pilot study with the first generation of patches that allow self-recordings of skin hydration.

Objectives: To evaluate the potency of a new skin hydration sensor patch in the fast self-recording of skin hydration.

Material And Methods: The Skin Hydration Sensor Patch (SHSP) turns the user's smartphone into a wireless skin moisture measuring device. The SHSP combines a capacitive measurement unit and Near Field Communication technology (NFC) for transmitting data and energy.

Comparing the self-perceived effects of a facial anti-aging product to those automatically detected from selfie images of Chinese women of different ages and cities.

Objective: To assess the agreement, after 1-month application of a popular and efficient anti-aging product, between self-perceived facial signs of aging and those detected and graded by an automatic A.I-based system, using smartphones' selfie images.

Material And Methods: Of 1065 Chinese women, aged 18-60 years, from eight different Chinese cities were recruited.

The respective weights of facial signs on the perception of age and a tired-look among differently aged Korean men.

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.

Japanese experiment of a complete and objective automatic grading system of facial signs from selfie pictures: Validation with dermatologists and characterization of changes due to age and sun exposures.

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.
