Hormonal changes, whether they occur in adolescence or adulthood, are a breeding ground for the onset or aggravation of acne. An imbalance between estrogen and progesterone levels, among other things, accentuates the appearance of the sign of acne.
Although heredity is not considered to be the only factor explaining the onset of acne, it plays an important role in it. Indeed, the risk of suffering from acne is five times higher when both parents have also been affected.
Some facial and hair products and makeup can promote acne, especially when they contain oily ingredients, such as silicon or are not suited to your skin type.
Several medications can exacerbate the problem, such as corticosteroids and certain antiepileptics, immunosuppressants and mood regulators.
When combined with other factors, the consumption of white bread, white rice, cookies, refined cereals and dairy products may promote the appearance of the signs of acne. The cause: the significant secretion of insulin that increases the release of androgens. Indeed, these hormones promote the hyperproduction of sebum in the pores of the skin, which makes them more sensitive to infection by the bacteria Propionibacterium Acnes responsible for acne.
Stress can cause and aggravate acne problems, as it increases the production of cortisol, adrenal androgens and insulin – hormones that influence the behaviour of the sebaceous glands and the production of sebum.
