• Combines Fast-Acting and Long-Lasting Effects
Visibly improves uneven skin tone, enlarged pores, and skin laxity within just 30 days.
Scientific skin rejuvenation, fearless of time
MD® Vitamin C is an advanced bio-active treatment, not a traditional cosmetic serum. Physician-formulated to bridge the gap between clinical procedures and daily topicals, this formula targets the three pillars of skin aging: oxidative dullness, recalcitrant hyperpigmentation, and dermal sagging."1. 20% L-Ascorbic Acid (USP-Grade)The highest clinical concentration of pure Vitamin C available. At 20%, the skin reaches its maximum absorption threshold (saturation point). This USP-grade active initiates immediate collagen signaling and neutralizes the free radicals responsible for structural aging and "digital fatigue" from blue light.2. High-Flux Ionic Water-BaseBy utilizing a purified, oil-free water matrix, we ensure a "High-Flux" delivery. This carrier allows the L-Ascorbic Acid to remain in its most potent, acidic state ($pH \approx 2.7$), driving the active ingredients directly into the dermis without the sticky residue or "metallic" scent found in stabilized oil serums.3. Precision Stability SystemOur medical-grade stabilization process ensures that the serum remains crystal clear and bio-available for up to 12 months. This ensures that every drop delivered to your skin is at peak potency, never oxidized, and never yellow.

Frequently Asked Questions
Because MD® Vitamin C s a pure water-based formula without irritating Ferulic Acid or synthetic fragrances, it is an excellent post-procedure antioxidant. Once the skin barrier has closed (typically 48–72 hours post-treatment), applying our 20% L-Ascorbic Acid helps provide the essential building blocks for collagen synthesis and prevents post-inflammatory hyperpigmentation.
High-Energy Visible (HEV) light from screens generates oxidative stress that leads to "digital dullness" and collagen breakdown. Clinical-grade 20% L-Ascorbic Acid acts as a molecular shield, neutralizing the specific free radicals triggered by blue light exposure. This makes it an essential daily treatment for professionals in high-tech environments.
To ensure maximum bioavailability. L-Ascorbic Acid requires a specific acidic pH (approx. 2.7) to penetrate the skin barrier. Applying a moisturizer (which usually has a neutral pH) too quickly can "buffer" or neutralize the Vitamin C before it reaches the dermis. The 10-minute "Ascorbic Gap" allows the serum to fully saturate the skin's reservoir for 72-hour protection.
While 20% is the maximum clinical strength for Vitamin C, MD® Ultimate is formulated with a high-flux water-base rather than heavy oils, which reduces the "trapped" heat sensation often associated with irritation. While a slight tingling is a normal sign of Active Saturation, our formula is designed to deliver high-potency anti-aging results with a focus on skin-barrier compatibility.
Clarity is the ultimate indicator of antioxidant stability. Many Vitamin C serums use Ferulic Acid or synthetic dyes to mask oxidation (turning orange or brown). MD® Ultimate is meticulously stabilized through a physician-formulated ionic matrix, ensuring the 20% L-Ascorbic Acid remains crystal clear and 100% bio-active for up to 12 months. If a serum is yellow, it has already begun to lose its potency.
