Blemished skin expresses itself in unevenness, pimples and inflammations. This skin condition lets those affected suffer a lot. Due to disorders of the sebaceous glands follicles, undesired comedones and pustules are formed. The causal factors are diverse and generally known: genetic predisposition, hormonal status, increased sebum production as well as keratinization disorder. Personal factors such as age, gender, profession, stress situations, lifestyle habits also have an influence on the skin condition. Latest studies confirm the influence of nutrition on the skin. Milk products and carbohydrates with a high glycaemic index can trigger skin impurities. These foods lead through an increased insulin release with diverse succeeding mechanisms to an increased development of sebum.
