Is Tretinoin common used ?

Tretinoin is the acid form of vitamin A and is also known as all-trans retinoic acid or ATRAT. Retinoin is used to treat acne. It is used by some as a hair loss treatment and also a component of many commercial products that are advertised as being able to slow skin aging or remove wrinkles.It promotes peeling of affected skin areas and unclogs pores. Tretinoin controls acne but does not cure it. http://www.ebiochem.com/product/tretinoin-18359

Tretinoin comes in topical liquid, cream, and gel. Tretinoin usually is used daily at bedtime or once every 2 or 3 days. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use tretinoin exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.Your acne probably will get worse (red, scaling skin and an increase in acne sores) during the first 7-10 days that you use this medication. Nevertheless, continue to use it; the acne sores should disappear. Usually 2-3 weeks (and sometimes more than 6 weeks) of regular use of tretinoin is required before improvement is seen.
