In a world where antibiotic resistance is becoming alarmingly widespread, interest in alternative ways to combat bacteria is growing. One such promising approach is phage therapy—the use of bacteriophages, or viruses that destroy bacteria. Although phages have attracted the most attention in the context of treating complex hospital infections, more and more researchers are exploring their potential in dermatology, particularly in the fight against acne and other skin conditions.

Why phages could be a breakthrough in acne treatment

Acne, or pimples, is more than just a cosmetic problem. It is often accompanied by pain, inflammation, psychological discomfort, and even the development of chronic dermatoses. One of the main factors contributing to the development of acne is the bacterium Cutibacterium acnes (formerly Propionibacterium acnes ).

Antibiotics, both topical and systemic, are traditionally used to treat acne. However, long-term use of these medications leads to bacterial resistance, making treatment less effective and sometimes even ineffective. In this situation, bacterial viruses, or bacteriophages, can offer an effective alternative.

Our microscopic allies have a unique ability to target specific types of bacteria and destroy them without harming other microorganisms. This means that phage therapy for acne can target specific bacteria without disrupting the skin's microflora—unlike antibiotics, which often destroy everything.

Scientific basis and clinical research

Although research into bacteriophages in dermatology is still in its early stages, encouraging results are already emerging. In 2021, a group of American scientists from the University of California published data confirming the activity of isolated phages against C. acnes . Some of these "bacteria hunters" demonstrated high efficacy in laboratory conditions, destroying even pathogen strains that were no longer responsive to conventional antibiotics.

Additionally, the Israeli biotech company BiomX is conducting clinical trials of personalized phage therapy for skin conditions, including acne. They are developing sprays and creams based on "good viruses" that specifically target Cutibacterium acnes without causing inflammation or allergic reactions.

Interestingly, bacteriophages have already been detected on the skin of healthy people. This means that the human body does not perceive them as foreign invaders, paving the way for the development of safe and natural dermatological products.

What else does science say: unexpected discoveries

Recent years have been crucial not only for isolating new phages but also for studying their behavior in the skin. For example, in 2022, a paper appeared in the journal Nature Communications demonstrating that bacteriophages not only kill C. acnes but can also reduce the inflammatory response by altering the local immune response. This offers the potential not only for clearing the skin but also for reducing redness, pain, and pustules—the main symptoms of acne.

Furthermore, researchers from France and South Korea are experimenting with modified phages carrying additional genes—for example, those that suppress the formation of bacterial biofilms (the protective shells that make bacteria highly resistant to drugs). By destroying these microbial "fortresses," bacteriophages could restore skin sensitivity to traditional treatments.

In Switzerland, a genetic platform for bacteriophages is being developed that will enable the creation of individualized viral cocktails for patients with different skin types and bacterial load levels.

Prospects for using phages in skin treatment

Bacteriophages have several key advantages that make them extremely promising in cosmetology and dermatology:

• Selectivity. The phage acts only on the target bacteria without disturbing the balance of the skin microbiome.

• Lack of resistance. Unlike antibiotics, bacteria rarely develop resistance to these viruses; and even if they do, the phage combination can be modified.

• Compatibility. Phages can be combined with other acne treatments, such as laser therapy, retinoids, chemical peels, and others.

In the future, acne treatment with bacteriophages may become the new standard, especially as antibiotics become less effective. Some cosmetic brands are already testing the addition of phages to creams, masks, and serums for problem skin.

Although acne phage therapy is not yet widely available, it has the potential to revolutionize dermatology. Its potential is supported by scientific research, clinical trials, and the interest of pharmaceutical companies worldwide. Amid the global antibiotic resistance crisis, these microscopic bacteria "hunters" could become not just an alternative, but the foundation of a new era in the treatment of skin infections.

Therefore, the question "myth or future?" sounds less and less rhetorical. Rather, it sounds like a future that's already on the horizon.
