“Nutritional deficiencies are often associated with skin health disorders, while diets can either positively or negatively influence skin condition. More recently, the concept of nutritional supplementation has emerged as a new strategy in the daily practice of dermatology as well as a complementary approach to topical cosmetics in the field of beauty. Focusing on human clinical data, this paper proposes to illustrate the link between skin health and nutrition and to exemplify the beneficial actions of nutritional supplementation in skin health and beauty.
In recent decades, the incidence of subjects presenting reactive skin has considerably increased in industrialized countries. Reactive skin is characterized by marked sensitivity of the skin to physical (heat, cold, wind) or chemical (topical product application) stimuli and occasionally by impaired ability for skin barrier function recovery. A recent study demonstrated that after 43 days of supplementation, a specific probiotic called L. paracasei decreased significantly skin sensitivity compared to placebo, and also increased the recovery rate of the skin barrier function induced by mechanical disruption.59
