Benzoyl gel (Benzoyl Peroxide) 5% 20g

Benzoyl gel 5% 20g acts on the skin in several directions at once. It has 4 important properties that help to get rid of acne at any age using the drug regularly. They are:

  • Antibacterial.
  • Anti-inflammatory.
  • Keratolytic.
  • Comedogenic.

The first property is antibacterial, based on the fact that benzene peroxide has a detrimental effect on the causative agent of acne called Propionibacterium acnes, as well as on Staphylococcus. When applied to the skin and further ingested in the inflamed sebaceous gland, it breaks down into two active components – benzoic acid and oxygen. The high concentration of it has a detrimental effect on all pathogens of acne.
Compared with all other drugs, it is Benzoyl gel 5% 20g that has the most severe antibacterial effect on pathogens of skin diseases. However, it should be remembered that even this potent product can be addictive with prolonged and uncontrolled use. It will negatively affect the therapy, since the microbes that cause acne will be completely insensitive to this drug.

  • The anti-inflammatory effect is due to the ability of the drug to reduce the production of sebum, as well as restore the protective shell of the epidermis.
  • The keratolytic (exfoliating) effect is due to the ability of Benzoyl Peroxide 5% 20g to reduce the build-up of excess cells, exfoliate dead cells and enhance the regeneration of healthy tissues. In this respect, the drug is somewhat similar to the most common face or body scrub.
  • The comedogenic effect allows you to get rid of the congestion in the sebaceous glands, which look like black dots. It also helps to remove from the sebaceous gland all the fat that has accumulated in it and for some reason is not able to get out.
