Survey on skin aging status and related influential factors in Southeast China

Abstract

Abstract:Objective: To investigate cutaneous aging patterns of residents in Hangzhou, Zhejiang, China, and their contributing factors. Methods: Eight hundred and forty-eight Hangzhou residents received the survey between March 2004 and September 2004. Results: Facial wrinkling first occurred at 21 years of age and skin elasticity began to lose at 22 years of age. In middle-aged and old people, facial wrinkling and looseness escalated with the increase of ultraviolet (UV)-exposure time, indicating the accelerating effect of a higher accumulative dose of UV radiation on skin aging. Only Fitzpatrick types II, III and IV were found in the skin phototypes of residents in Hangzhou area, and Fitzpatrick type II seemed to be much more subject to severe wrinkling, elasticity destruction and skin tumors than types III and IV. The oily skin was more protected against wrinkling and facial looseness than dry skin. However, as to concomitant cutaneous diseases, no difference was found among different skin types. Conclusion: Age, solar-exposure time, Fitzpatrick type and skin type are the associated forces in promoting skin aging, and emotional factor seems to be another independent risk factor. The age of 49 years and 2 h/d of solar-exposure time seem to be the turning points responsible for dramatic changes of cutaneous appearance in the process of skin aging in Southeast China.

Efficacy Evaluation of a Multifunctional Cosmetic Formulation: The Benefits of a Combination of Active Antioxidant Substances

“…Once oxidative stress has been suggested to play a role in ultraviolet (UVA) damage mediated melanogenesis and reduction on skin elasticity, through promoting oxidative stress, which occurs as the result of increased formation of oxidants and/or reactive nitrogen species (RNS) including nitric oxide (NO), this effect of improvement on skin color and appearance of pores could be related to the active antioxidant substances associated in the multifunctional studied formulation [26,27,28,29,30].…”

The dermoscopic features of facial aging among Egyptians: A comparative study between males and females

“…Wang et al (2009) carried out a study about skin aging and related influential factors in Southeast China which showed that the incidence of seborrheic keratosis increases with increasing the duration of exposure to sun light and in correlation with skin phototype. They stated that the incidence of seborrheic keratosis was higher among patients with skin phototype II than those with skin phototype III and IV, and in correlation with age, they reported higher incidence of seborrheic keratosis in older age.…”

“…These results were in agreement with the results observed by others. 2,7 Wang et al (2009) 12 carried out a study about skin aging and related influential factors in Southeast China which showed that the incidence of seborrheic keratosis increases with increasing the duration of exposure to sun light and in correlation with skin phototype.…”

Factors Associated with Premature Skin Aging (Photoaging) before the Age of 55: A Population-Based Study

“…Although histological detection of dermal elastosis in skin tissue samples is considered the ‘gold standard’ in diagnosing photoaging, clinical diagnosis with noninvasive techniques is clearly preferable. The easiest and most popular technique is highly subjective: counting or scoring of visible wrinkles and other changes [6,7,8,9]; objective techniques include measurement of skin extensibility [10] and assessment of skin topography using silicone impressions [11,12]. Few investigators have examined factors associated with any of these photoaging measurements however.…”
