Eyebrows frame your face — but factors like over-tweezing, aging, or stress can leave them sparse and fragile. Most brow serums offer temporary fixes. MD® Eyebrow Conditioner is different.

Developed by Dr. Susan Lin, a physician with 35+ years of clinical experience, this 3 mL powerhouse leverages clinical science to nourish follicles, reduce breakage, and stimulate natural growth. Trusted in 20+ countries, it's the secret behind fuller, healthier brows — naturally.

Introduction Why Your Brows Need Medical-Grade Care

The delicate anatomy of the eyebrow requires more than just surface-level hydration. Unlike the rapid turnover of scalp hair, eyebrows have a longer telogen (resting) phase, making them highly susceptible to thinning from environmental stressors and physical trauma like over-tweezing.

MD® bridges the gap between luxury beauty and medical science, offering a physician-formulated solution for those seeking unparalleled results.

Formulation Precision-Engineered for Brow Growth

Brows grow slower than scalp hair, requiring targeted care. The MD formula combines clinically proven actives designed to work in synergy:

Clinical Evidence The 56-Day Clinical Study

To ensure the highest standard of safety and efficacy, MD Eyebrow Conditioner underwent a rigorous 56-day independent clinical study. The protocol was designed to monitor the transition of sparse brows through two complete cellular turnover cycles.

Performance Benchmarks

• 83% saw visibly thicker brows by the 6-week mark.
• 91% reported significantly reduced breakage due to improved hair elasticity.

Dermatological Research Ingredient Deep-Dive

Advanced Peptide Complex

Literature suggests that lipo-oligopeptides like Myristoyl Pentapeptide-17 enhance the expression of keratin genes. By increasing the available building blocks at the follicular level, the serum helps brows reach their maximum natural potential — without the use of harsh prostaglandins.

The Role of Biotin (Vitamin B7)

Biotin serves as a vital cofactor for carboxylase enzymes. In tissues with high biosynthetic activity — like the hair follicle — Biotin supports the metabolism of amino acids, which is critical for the production of healthy, resilient hair.

Physician's Priority Safety First

Safety is a cornerstone of the MD brand. MD Brow® serum is formulated without parabens or harsh fragrances, making it ideal for individuals with sensitive skin or those who wear contact lenses.

Biology Why Brows Thin Over Time

Eyebrows do more than frame the face — they are complex biological structures with delicate follicles that require medical-grade attention to thrive. While many over-the-counter products simply coat the hair surface for a temporary effect, MD® Eyebrow Conditioner represents a breakthrough in dermal science.

Developed by Dr. Susan Lin, a physician with over 35 years of clinical experience, this formula penetrates the dermal-epidermal junction to nourish brows at the root.

Unlike scalp hair, eyebrow hairs have a much shorter active growth phase (anagen) and a longer resting phase (telogen). Factors such as aging, environmental stress, and years of over-tweezing can cause follicles to become dormant or produce thinner, more brittle strands.

To combat this, MD® utilizes a Molecular Hydration System where Panthenol molecules bind moisture at the cellular level — thickening each strand from within, rather than masking it on the outside.

Technology Precision-Engineered Active Complexes

The effectiveness of the MD® formula lies in its high-concentration, physician-developed active complexes:

• Fortifying Biotin Complex: Clinically shown to increase keratin production by 27%, providing the essential protein needed for hair strength and resilience.
• Proprietary Peptide Blend: Stimulates dormant follicles in 89% of users, encouraging a fuller and more defined brow line.
• Antioxidant Defense: Infused with Algae and Grape Seed extracts to protect delicate follicles from oxidative stress and environmental damage.

Clinical Results Real Evidence: The 56-Day Transformation

Trust in beauty comes from clinical validation. In independent user trials, the MD formula consistently outperformed traditional cosmetic serums:

Ritual The MD® Nightly Ritual for Success

To achieve professional-grade results, consistency is vital. Because the formula is a 3 mL powerhouse concentrate, a little goes a long way.

1. Cleanse

   Ensure brows are clean and completely dry before application.

2. Apply

   Use the precision applicator to apply one thin stroke to the base of the brows nightly.

3. Absorb

   Allow 5 minutes for the serum to fully penetrate before applying other skincare or makeup.
