Isotretinoin

Where is Isotretinoin used?

Isotretinoin is used for the treatment of severe acne. This is in a group of medications called retinoids which are derivatives of vitamin A. The Food and Drug Administration (FDA) has already approved this medication.

How does Isotretinoin work?

Isotretinoin works by reducing the production of the skin’s natural oil which is called sebum. It blocks the sebaceous glands that stop the oil from flowing easily out and reasons to a sebum build-up under the skin. They feed on the sebum and create unused produce and fatty acids that annoy the sebaceous glands that make them inflamed and cause spots. 

This medication reduces the size and activity of the sebaceous glands in the skin which also lessens the amount of sebum that is produced. This stops the glands from becoming blocked. It means that the bacteria are less likely to thrive. It also decreases the inflammation in the skin. 

Your acne may get worse when you first start taking Isotretinoin. But, it usually starts to improve within 7 – 10 days of treatment. Most people discover that their acne clears up with a 16 – 24 week of treatment. You’re then likely to remain free of acne for a long time.
