[Skin aging exposome].

The skin is a barrier organ and thus exposed to environmental factors from birth, which essentially determine skin aging. In order to describe and understand this complex process exactly, we applied the concept of the "exposome" to the environmentally induced skin aging process. In this review, we summarize current knowledge on the skin aging exposome.

An oral French maritime pine bark extract improves hair density in menopausal women: A randomized, placebo-controlled, double blind intervention study.

Background And Aims: Female pattern hair loss affects females of all ages with a trend to increase after menopause. This disorder may have significant psychological impact and lead to anxiety and depression.

Objective: In a single center, double blind, randomized, placebo-controlled study, the effects of oral Pycnogenol® intake (3 × 50 mg/day for a total of 6 months) on hair density, scalp microcirculation, and a variety of skin physiological parameters was studied in Han Chinese menopausal women ( = 76) in Shanghai, China.

Efficacy of a topical serum containing L-ascorbic acid, neohesperidin, pycnogenol, tocopherol, and hyaluronic acid in relation to skin aging signs.

Background: Skin aging is a process regulated by chronological aging and amplified by exposome factors including chronic UV exposure and pollution, which both induce reactive oxygen species. Topical antioxidants have the potential to counteract this process and to improve skin aging signs, including wrinkles and hyperpigmentation.

Objective: To evaluate the efficacy of a topical antioxidant serum containing 15% L-ascorbic acid, neohesperidin, Pinus pinaster bark, tocopherol, and hyaluronic acid (HA) ex vivo on air pollution-induced pigmentation and gene expression, as well as in vivo on skin aging signs in Brazilian volunteers, after 90 days of use.
