What is acne?

The skin’s surface is covered with pores that connect to sebaceous glands beneath the skin. The glands produce an oily and sticky liquid called sebum, which contributes to keeping skin healthy when produced in normal quantities. However, when sebaceous glands secrete excess sebum, they cause dead skin cells, which normally exit the pore of the hair follicle, to stick together. The accumulation of dead skin cell debris and oily sebum blocks the pore of the hair follicle, thus forming a microcomedone which we commonly refer to as a pimple.

What causes acne?

There are different risk factors that can lead to acne such as genetic predisposition, stress, environment. Acne is also commonly know to be triggered by hormonal fluctuations in the body. Certain hormones also known as androgens are excreted in the body and stimulate the sebaceous gland to secrete sebum.

Do certain foods cause acne?

One theory that remains unclear is that diet influences hormonal changes and ultimately cause acne. To date, diet or food consumption is a theoretical factor which is still a debate amongst the medical community. Some studies link high glycemic index diets or diets high in sugar or carbohydrates to acne, but research is not conclusive. While studies have not been able to show the direct correlation between nutrition and acne, all factors including food need to be considered when getting a medical diagnosis. In order to increase the chances of acne prevention, we recommend that you follow an optimal daily skin routine and visit doctor for more severe cases.

How to prevent acne?

Step 1: Remove Impurities


Start with a gentle purifying cleanser with a physiological pH such as the Effaclar Purifying Foaming Gel. This is an important step as cleansing removes impurities that thrive in oily conditions.

Step 2: Unclog Your Pores


Next, use an exfoliator with an astringent action to unclog pores and reduce their size such as Effaclar Astringent Micro-Exfoliating Lotion.

Step 3: Use a Daily Acne Treatment


Finally, use a global acne treatment accross your entire face to treat your current acne as well as prevent their reoccurence. Effaclar Duo (+) Global Action Acne Care is a 24h hydration lotion that will help to reduce acne pimples, while helping your skin to heal. If you suffer from severe acne, we recommended that you seek the advice of a board-certified dermatologist.

Step 4: Use Sun Protection


In case of daily UV exposure, use a sun protection with a minimum SPF30.
