Skin and Acne
Acne, including the most common form is acne, about 80% of adolescents and heals spontaneously by the age of 19 years in 90% of cases, leaving no scars.

The sebum (oily substance secreted by sebaceous glands of the skin) accumulates, and there is also hyperkeratosis (overproduction of keratin) and bacterial overgrowth. It occurs when inflammation of the sebaceous follicles, causing the formation of open comedones (blackheads) or closed (microcysts), papules, pustules (whiteheads) or nodules (lumps).
Acne occurs mainly in areas of high concentration of sebaceous glands, especially on the face, neck, chest and back.

Antibiotics
They work by destroying or inhibiting the bacteria involved in inflammatory buttons. Treatment duration of at least three months, but relapse is frequent stop. It is advisable to repeat the treatment for three months. An additional local treatment is often associated.
Zinc
It also affects inflammatory buttons. In the absence of improvement after the first month, another treatment is considered.

Because of its limitations and its side effects, isotretinoin tablets are reserved for severe acne or acne has resisted conventional therapies (antibiotics associated with local treatment).
This substance acts on multiple targets, the main one being the inhibition of secretion of sebum by the sebaceous gland.
Treatment is started at low doses and should generally be continued over 6 months.
Often, improvement begins at the end of the first month after an apparent worsening of the buttons at day 15.
Again, there is a risk of relapse upon discontinuation of treatment.
