MD-03 Protocol combines microbiome testing, clinical consultations, and personalized phage skincare subscriptions.
MD-03 Protocol is Parallel Health's subscription service combining skin microbiome assessment with clinician support and personalized skincare. Members send skin samples for genomic analysis, receive a skin health report, and discuss the findings with a provider before receiving a serum selected for their microbial profile.
The program sequences testing, skincare preparation, and serum delivery across its initial months. Active subscribers receive continuing clinical support, recurring serum shipments, and access to microbiome retesting. It addresses individualized skin concerns through a clinician-led process rather than a single standardized skincare formulation.
