Acne affects roughly 50 million people in the US each year, with breakouts ranging from blackheads and whiteheads to painful cysts. Standard treatments include retinoids, antibiotics, benzoyl peroxide, and isotretinoin for severe cases. Research now focuses on alternatives to antibiotics, new anti-inflammatory approaches, and treatments that address the skin microbiome.

What's actually going on in research

Trials are testing topical drugs that block specific inflammatory pathways, new retinoid formulations with fewer side effects, and treatments targeting bacteria without antibiotics. Researchers are also studying the skin microbiome to understand why some people develop acne and others don't, and testing probiotics and bacteriophage therapies.

Microbiome-targeted treatments

Studies are testing live bacteria that compete with acne-causing organisms, and bacteriophages that kill harmful bacteria while leaving helpful ones alone. Early data suggest these approaches may work without the resistance problems that antibiotics create.

IL-17 and IL-23 blockers

Drugs already approved for psoriasis are being tested in acne, targeting inflammation without antibiotics. These injections or pills might offer an alternative for people with severe acne who can't tolerate isotretinoin.

What to know before you search

Eligibility typically depends on acne severity (mild, moderate, or severe), prior treatments tried, and whether hormonal factors or scarring are present.

What types of trials are currently open

  • Topical treatment trialsTesting new creams, gels, or foams that reduce inflammation or kill bacteria, often compared to standard treatments like adapalene or benzoyl peroxide.
  • Oral medication trialsTesting pills that target inflammation or hormones involved in acne, aiming to match the effectiveness of isotretinoin with fewer side effects.
  • Microbiome trialsTesting probiotics, bacteriophages, or other treatments that change the balance of bacteria on the skin.
  • Device trialsTesting lasers, light therapy, or other devices that reduce acne inflammation or bacterial counts.
  • Natural history studiesFollowing people with acne over time to understand what drives severity, scarring, and response to treatment.
