What is isotretinoin?

In its pure form, isotretinoin is a powder of a bright orange or slightly yellowish hue without a pronounced smell. This substance belongs to the class of active biological form of vitamin A, responsible for the tone and condition of the skin, as well as the work of all skin secretions.

The substance does not enter into direct reactions with the nuclear receptors of retinoic acid. In this case, isotretinoin rapidly changes its properties and becomes tretinoin. Thanks to such processes, buying isotretinoin, there are disruptions in the work of dangerous genes that cause protein resolution.

At the same time, there is a decrease in the secretion of sebaceous glands, which helps to get rid of the manifestations of acne. Notable results from the use of retinoids are visible already in the middle of the course of treatment.

The effect of Tretizen 20 on the skin and body

After entering the body, an instantaneous reaction of isotretinoin into the form of tretinoin takes place, which in turn triggers the following processes: 
• removal of inflammatory processes caused by clogging of pores and excessive sebaceous glands; 
• Establishment of sebum production; 
• elimination of traces and manifestation of seborrhea; 
• decrease in the number of bacteria that cause and provoke acne; 
• stimulation of renewal of epidermal cells; 
• additionally keratolytic effect occurs.

It should be noted that isotretinoin refers to the retinoids of the natural and physiological class, which causes its rapid and easy absorption by the skin cells.
