Abstract:

Intense pulsed light (IPL) is a continuous, multi-wavelength, incoherent broad-spectrum light with a wavelength of (500 to 1 200) nm. In this research, a total of 31 female volunteers at the age of 23.39±1.41 years were recruited to get half-face IPL irradiation at the Air Force Medical Center, PLA. Indexes as stratum corneum water content, transepidermal water loss (TEWL), sebum content, pH value, erythema index and melanin index were observed and discussed, together with the analysis of facial skin surface lipid (SSL) conducted by ultra-performance liquid chromatography with quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) combined with OPLS-DA (Orthogonal Partial Least Squares-Discriminant Analysis) mode based on samples prior of (PI) and after (AI, One week after IPL irradiation) IPL irradiation. The results indicate that water content of the stratum corneum (P=0.024) significantly increase in AI compared with PI. However, the remarkable decrease of melanin index (P<0.001) and erythema index (P<0.001) in AI is detected. And there are no sufficient changes in TEWL value, pH value, and sebum content. Additionally, a total of 1 704 lipids are detected and 60 different facial SSL lipids are further screened between PI and AI. Differential lipids are divided into 7 categories, of which 5 major types -[FA], [SP], [ST], [PR], [PK] are excessively degraded after IPL irradiation. The content of 16 subclass is significantly different between PI and AI, all of which are AI lower than PI. Ceramides (CERs) are the main differential lipids, and the content in AI is lower than PI. While the CERs levels are related to skin barrier damage. This provides new ideas for the development of lipid-added skincare products after IPL irradiation.
