Reviews on Isotrexin

Isotrexin gel: dermatologist reviews

The original instructions for the drug say that the main indication for use will be the treatment of acne. Recall that acne is nothing but fatty plugs in the pores of the skin (located at the mouth of the hair follicles), consisting of the fat secretion of the sebaceous glands and desquamated epithelial cells of the hair follicle.

0.05% Isotretinoin, which is part of the drug, perfectly reduces the secretion of fat secretion by the sebaceous glands, and also normalizes the keratinization processes of the hair follicle epithelium, which will lead to a sharp decrease in the number of desquamated epithelial cells in the follicle lumen. All this will really prevent the formation of fatty plugs (blackheads).

But! The composition of the drug also includes the antibiotic erythromycin in an effective therapeutic concentration of 2.0%, which is necessary to suppress pathogenic microflora, due to which acne is transformed into acne (in the form of papules or purulent pustules). Creams and gels with this antibiotic are actively prescribed by dermatologists only for the treatment of acne that has already arisen.

findings : this drug will be very effective in the combined form of acne, i.e. when you have acne and acne at the same time. But it should not be used if you only have acne, but no acne. The latter is due to the fact that microflora is gradually getting used to any antibiotics, and the moment may come when the bacteria (causing acne) become much more aggressive and insensitive to antibiotics.

And it is not necessary to apply, including if necessary, the prevention of the appearance of purulent acne. To prevent the appearance of acne, it is best to use not antibacterial drugs at all, but best of all - antimicrobial gels and lotions based on the benzoyl peroxide antiseptic.
