Analysis of the correlation between skin barrier function and age in rosacea patients in Qinghai region.

OBJECTIVE

This study aims at investigating the difference in facial skin barrier function between rosacea patients and the healthy population of different ages in the Qinghai region and its correlation with age, providing a basis for clinical nursing and treatment.

METHODS

The data of 216 rosacea patients were collected, and 211 healthy testers were selected as the control group. The skin barrier characteristics of rosacea patients of different ages were evaluated by comparing transepidermal water loss (TEWL), stratum corneum hydration (SCH), sebum content (SC), and pH values between the two groups. Then, the correlation between skin barrier function and age in rosacea patients and the healthy population was analyzed.

RESULTS

In all four age groups, the TEWL of the rosacea group was higher than that of the healthy control group, and the epidermal hydration was lower than the healthy control group. In the population aged over 40, the sebum content in rosacea was lower than that in the healthy control group. In the age group of 40-59, the pH value of the rosacea group was higher than the healthy control group. In both the rosacea and the control groups, TEWL was positively correlated with age, and epidermal hydration was negatively correlated with age. The sebum content in rosacea group was negatively correlated with age (p < 0.05).

CONCLUSION

As age increases, the facial epidermal function of both rosacea patients and the healthy population declines. Therefore, with increasing age, attention should be paid to enhance the epidermal function to slow down the skin aging process.
