Isotretinoin is a common ingredient in medications prescribed by dermatologists and doctors for nodular and severe acne that does not respond well to other types of treatment. This is a potent ingredient with a high success rate in the treatment of acne, although it may also have various side effects.
Isotretinoin is derived from vitamin A and is also called the vitamin A analog or retinoid. This ingredient is commonly found in skin care products which are typically prescribed in dosages of 10-40 milligrams per day.
In most cases, it has to be used for a minimum period of 4-5 months for it to be effective.
Isotretinoin works in reducing sebum
This ingredient works in dramatically reducing the size and sebum production of the sebaceous oil glands in the skin. An excess in sebum results in oily looking skin which may cause clogged pores, while decreasing the natural shedding of dead skin cells. An excess of oil and dead skin cells are able to stick together to create plugs in pores which become inflamed due to bacterial growth, thereby causing acne.
Isotretinoin works in normalizing keratinatization or the shedding of dead skin cells from the surface of the skin. This aids in the reduction of acne and clogged pores, minimizes acne scars and pigmented blemishes, while evening out the complexion of the skin.
It also assists in the reduction of inflammation responsible for causing redness and raised bumps whenever there is a breakout of acne. This dramatic reduction of sebum output also reduces the bacteria that causes acne.
