Skin phototyping in a Chinese female population: analysis of four hundred and four cases from four major cities of China

Abstract

From the study we concluded that the skin types of the investigated Chinese females are principally type III (more than 70%), and then type II and type IV. The different ways of answering the questionnaire did not affect the results remarkably. The measurements of photobiology parameters confirmed that there is a certain correlation between skin types and MED or MPPD determined in this group of volunteers.

A split‐face study of intense pulsed light on photoaging skin in Chinese population

“…[9]. Exclusion criteria included retinoid use within the previous 6 months, history of keloid formation, pregnancy, and unequal photodamage on both sides of face at baseline.…”

Reliability of skin‐type self‐assessment: agreement of adolescents’ repeated Fitzpatrick skin phototype classification ratings during a cohort study

“…This focus may reflect the FSPC’s origins as an instrument for calculating doses of Ultraviolet A to be administered during PUVA therapy 1 . The results of such studies of FSPC and MED have shown significant association or correlation of FSPC and MED, with the relationship appearing to be of moderate degree 8–12 …”

“…Sayre et al. 8 showed FSPC to be statistically significantly related to MED in white subjects, as did Liu 9 in Chinese subjects. Baron et al.…”

Topical Grape Seed Proanthocyandin Extract Reduces Sunburn Cells and Mutant p53 Positive Epidermal Cell Formation, and Prevents Depletion of Langerhans Cells in an Acute Sunburn Model

“…12 This sun simulator includes a 450 W xenon lamp and a dichroic mirror. Radiation was filtered with a WG 320, 1-mm thick short cutoff filter, plus a UG 11, 1-mm thick long cutoff filter (Schott, Clichy, France) to deliver a continuous UV spectrum from 290 to 400 nm for the measurement of MED and solar simulated radiation (Fig.…”
