MD® Wellness Clinical Evidence — Peer-Reviewed Research Behind Active Ingredients
MD® Wellness Clinical Evidence
Peer-Reviewed PubMed Research Behind MD® Wellness Active Ingredients · Curated by Dr. Susan Lin, M.D. · Reviewed: June 2026
Summary of Evidence
MD® Wellness spans two product types: topical wellness (intimate hygiene and restoration serums) and oral wellness (daily nutrient supplements for skin tone and hair density). Every active ingredient is supported by peer-reviewed research indexed in PubMed (US National Library of Medicine).
The published evidence spans:
- Topical Antimicrobial + Microbiome Support — Nano Silver (silver nanoparticles)
- Topical TRPM8 Cooling + Comfort — Peppermint Essential Oil / Menthol
- Topical Hydration — Hyaluronic Acid (Sodium Hyaluronate)
- Oral Skin-Tone Brightening + Antioxidant Recycling — Reduced L-Glutathione, Alpha-Lipoic Acid, Vitamin C
- Oral Hair Density Support — Marine Collagen Peptides, Biotin, Verbascoside (Lilac stem-cell extract)
Inclusion levels in MD® Wellness formulations are engineered to align with the dosages used in cited clinical trials. All formulations are hormone-free and drug-free.
1. Topical Antimicrobial + Microbiome Support — Nano Silver
Silver Nanoparticles (Nano Silver)
Wellness benefit: Broad-spectrum antimicrobial activity from sustained release of silver ions, reducing odor-causing bacterial colonization in intimate and skin-fold areas without disrupting beneficial flora. Lower percutaneous absorption profile than silver sulfadiazine.

2. Topical TRPM8 Cooling + Comfort — Peppermint Essential Oil
Menthol (active component of Peppermint / Mentha piperita)
Wellness benefit: Activates the TRPM8 cold-sensitive cation channel in cutaneous sensory neurons, producing a clean cooling sensation. Studied for analgesic and itch-relieving effects on inflamed or irritated skin without the rebound vasodilation of warming agents.

3. Topical Hydration — Hyaluronic Acid
Sodium Hyaluronate
Wellness benefit: Binds up to 1,000× its weight in water; supports the natural moisture barrier of delicate intimate and skin-fold skin without occlusive oils.
4. Oral Skin-Tone Brightening + Antioxidant Recycling
Reduced L-Glutathione (pharmaceutical-grade)
Wellness benefit: Glutathione is the body's master intracellular antioxidant. Oral supplementation inhibits tyrosinase activity (the rate-limiting enzyme in melanin synthesis), shifting melanocyte output from darker eumelanin to lighter pheomelanin and supporting a more even, luminous complexion.
