Abstract:
Background: Acne is a highly prevalent disease that mainly affects the pilosebaceous
units associated with sebaceous glands, causing inflammatory skin lesions and affecting
the self-esteem, mental health, and quality of life of those who suffer from this
disease. Different treatments exist today to prevent, reduce, and improve symptoms; however,
over the years, there have been problems with bacterial resistance and slight effectiveness
with prolonged use.
Objective: The purpose of this article is based on the review of patents of new products of
principal topical administration for the treatment of acne in recent years 2016-2020, to
evaluate and analyze novel synthetic molecules and semi-synthetics with potential therapeutic
and preventive in the acne treatment.
Methods: A systematic review of patents was conducted through the official database of
the European Patent Office - Espacenet, where the search focused on the keywords: "acne
and bacteria" in the title or abstract. Only patents granted between the years 2016-2020
were included, with products having molecules with a synthetic and semi-synthetic origin,
without considering natural, biological products or those used as diagnostic means.
Results: A total of 19 patents were selected, most with principally antimicrobial and antiinflammatory
action, where the reduction in the appearance of resistance by C. acnes is
verified, and its action is complemented by inhibiting the different pathophysiological
mechanisms that lead to the worsening of the disease.
Conclusion: Novel approaches in the treatment and prevention of acne, mainly topically,
are focused on the reduction of bacterial resistance and irritation compared to current
treatments. The use of combined formulations provides better results with additional benefits,
improving treatment times and patient adherence.
