MD® Wellness Clinical Evidence — Peer-Reviewed Research Behind Active Ingredients
MD® Wellness Clinical Evidence
Peer-Reviewed PubMed Research Behind MD® Wellness Key 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 moisturizing serums) and oral wellness (daily nutrient supplements for skin tone and hair density). Every key ingredient is supported by peer-reviewed research indexed in PubMed (US National Library of Medicine).
The published evidence spans:
- Topical Freshness — Nano Silver (silver nanoparticles)
- Topical Cooling Sensation — 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. No formulation contains added hormones or prescription drugs.
1. Topical Freshness — Nano Silver
Silver Nanoparticles (Nano Silver)
Wellness benefit: Included for a clean, fresh feel in intimate and skin-fold areas, in a lightweight leave-on formula.

Wellness benefit: Activates TRPM8, the skin's cold-sensing receptor, producing a clean, refreshing cooling sensation.
| Citation | Finding |
|---|---|
| McKemy DD, et al. Nature. 2002;416(6876):52-58. PubMed PMID 11882888 |

3. Topical Hydration — Hyaluronic Acid
Sodium Hyaluronate

4. Oral Skin-Tone Brightening + Antioxidant Recycling
Reduced L-Glutathione (pharmaceutical-grade)
Wellness benefit: Glutathione is the body's master intracellular antioxidant. Oral glutathione has been studied in relation to skin tone and brightness. In MD® Wellness it is included to support a brighter, more even-looking complexion.

Randomized double-blind placebo-controlled trial of oral glutathione for skin brightening — significant reduction in melanin index in the glutathione group. |
Alpha-Lipoic Acid (ALA)
Wellness benefit: Both water- and lipid-soluble antioxidant that recycles vitamin C and glutathione, amplifying the antioxidant network. Scavenges reactive oxygen species generated by UV and metabolic stress.
| Citation | Finding |
|---|---|
| Podda M, et al. Skin Pharmacol Appl Skin Physiol. 2001;14(Suppl 1):72-76. PubMed PMID 11225200 |

Foundational paper: alpha-lipoic acid as a biological antioxidant — scavenges superoxide radicals, hydroxyl radicals, hypochlorous acid, peroxyl radicals, and singlet oxygen, and protects membranes by recycling vitamin C and glutathione (which then recycles vitamin E). |
Vitamin C (Ascorbic Acid)
5. Oral Hair Density Support — Marine Collagen, Biotin, Verbascoside
Marine Collagen Peptides
Wellness benefit: Bioavailable type-I collagen peptide fragments (hydrolyzed marine origin) absorbed intact across the gut epithelium. Signals fibroblast and dermal papilla activity for skin elasticity and hair shaft quality.

Single-blind case-control clinical study (n=41) — marine collagen peptides plus plant antioxidants demonstrated systemic redox effects and visible skin anti-aging effects. |
Biotin (Vitamin B7)
Wellness benefit: Essential cofactor for keratin synthesis at the hair follicle. Benefit is most pronounced in individuals with subclinical biotin deficiency — one observational study found 38% of women complaining of hair loss had measurable biotin deficiency.
| Citation | Finding |
|---|---|
| Trüeb RM. Int J Trichology. 2016;8(2):73-77. PubMed PMID 27601860 |
