Summary

This trial will analyze the lipidome and microbiome of subjects with acne in order to better understand the role of these substances in the development and treatment of acne.

Who is the study for?
This trial is for individuals aged 15 and older who have acne diagnosed by a dermatologist and are prescribed or eligible for Doxycycline. They must understand the study procedures and consent forms. Excluded are those with certain chronic diseases, recent antibiotic use, allergies to tetracyclines, high BMI, or on specific medications.
What is being tested?
The study examines how Doxycycline affects the lipidome (fats in blood and skin) and microbiome (bacteria in gut and skin) of people with acne compared to controls without treatment. It aims to understand changes due to antibiotics in these biological profiles.
What are the potential side effects?
Doxycycline may cause side effects such as stomach upset, diarrhea, sun sensitivity, discoloration of teeth if used long term in children under age 8, rash or allergic reactions.
