Parallel Health products for Human Health
The MD-03 Protocol™ is Parallel Health’s flagship precision dermatology program, representing a comprehensive approach to skin health that moves beyond treating symptoms to address the root cause of the patient’s unique skin microbiome. The protocol integrates three core steps:
- Test – Members begin with an at-home Skin Discovery Test that uses whole genome sequencing to provide a detailed analysis of their microbial composition, including a Skin Microbiome Type™ assessment and antibiotic resistance score.
- Reset – Based on the test results, members receive a personalized Skin Health Report and a 1:1 medical consultation with a board-certified dermatologist to create a customized treatment plan.
- Rebalance – The cornerstone of the protocol is a monthly delivery of a Custom Active Phage Serum. This serum is precision-formulated with bacteriophages specifically selected to target the harmful bacteria identified on the member’s skin, effectively eliminating pathogens without disrupting the beneficial microbes essential for a healthy skin barrier.
The MD-03 Protocol™ addresses a wide range of conditions, including acne, rosacea, eczema, hidradenitis suppurativa, body odor, and signs of aging such as fine lines and loss of elasticity. Clinical results from a dermatologist-led study showed a 99.9% reduction in inflammation and blemishes. The program is structured as a membership that includes semi-annual retesting, unlimited telehealth consultations, and clinical support, and is HSA/FSA eligible.
