Area of Science:

  • Dermatology and cosmetic science
  • Image analysis and perception science

Background:

  • Skin gloss is a crucial indicator of skin health and beauty.
  • Objective quantitative evaluation of skin gloss perception remains a challenge.
  • Understanding factors influencing perceived glossiness, mattness, and greasiness is vital for cosmetic and skincare product development.

Purpose of the Study:

  • To investigate factors affecting the perception of matte, glossy, and greasy skin in Korean women.
  • To explore the role of surface reflection characteristics in skin gloss perception.
  • To establish objective parameters for evaluating skin gloss.

Main Methods:

  • Visual evaluation of skin gloss using modulated images with varying surface reflections.
  • Participant classification of images into matte, glossy, and greasy categories.
  • Multinomial logistic regression analysis to identify significant influencing factors.

Main Results:

  • Low-frequency mean (LFM) and high-frequency standard deviation (HFSD) of surface reflection significantly influenced perception.
  • Increased LFM and HFSD shifted perception from matte to glossy and greasy.
  • The number and area of highly glossy objects differed significantly across perceived categories.

Conclusions:

  • Identified LFM, HFSD, number, and area of highly glossy objects as key factors in skin gloss perception.
  • Evenness of shine was identified as a critical factor for perceiving greasiness.
  • These parameters provide a basis for objective skin gloss and greasiness evaluation.
