MD Complete by Dr. Brian Zelickson Retinol Vitamin C Concentrate Serum 0.5 fl oz — High-Potency Brightening & Anti-Aging

MD Complete Retinol Vitamin C Concentrate Serum is a high-potency anti-aging concentrate that pairs stabilized vitamin C with retinol and nourishing oils to brighten tone, boost radiance, and visibly smooth fine lines.

This concentrated 0.5 fl oz formula from MD Complete by Dr. Brian Zelickson combines a clinically advanced form of vitamin C (tetrahexyldecyl ascorbate), retinol, vitamin E, carotenoids, omega fatty acids, and fruit seed extracts in a delivery system designed for faster absorption and stronger activity than typical over-the-counter serums. It's formulated to deliver professional-level results—improved clarity, faster brightening, and accelerated reduction in the appearance of texture and fine lines—while remaining free of parabens, phthalates, and animal-derived ingredients.

How quickly will I notice brighter, more even skin tone?

Many users report improved brightness and skin tone clarity within 7–14 days thanks to the stable vitamin C ester and fruit seed antioxidants. Continued use over 60–90 days typically produces more pronounced smoothing and reduction in fine lines as retinol and supportive nutrients work cumulatively.

• Initial radiance often visible in 1–2 weeks
• Noticeable texture and fine-line improvements in 2–3 months
• High-potency vitamin C for consistent brightening

Can this serum be used with other retinol or vitamin products?

This concentrate is formulated to be potent, so pairing it with other strong retinoids or high-dose actives should be done carefully. If you already use professional-strength retinols, introduce this serum gradually or consult your skincare professional to avoid irritation.

• Start with every other night if new to retinol
• Layer with hydrating, non-acid moisturizers to reduce sensitivity
• Avoid simultaneous use with other strong exfoliating acids without guidance

What makes the ingredient delivery system different?

The proprietary delivery method increases ingredient bioavailability so higher concentrations of actives like retinol and vitamin C penetrate more effectively. This system supports fresher, more active ingredients in each drop for performance comparable to in-office dermatologist formulas.

• Enhanced absorption for faster visible effects
• Up to multiple times higher active levels than many department-store serums
• Formulated for stability and skin compatibility

How should I incorporate this serum into my routine?

Apply a small amount to clean, dry skin in the evening, followed by a moisturizer. Use sunscreen during the day when using retinol-containing products; gradual acclimation is recommended for sensitive skin types.

• Apply 2–3 drops to face and neck at night
• Follow with a soothing moisturizer to minimize irritation
• Use broad-spectrum SPF daily to protect results

Who is this for: This serum is intended for adults seeking a high-potency, dermatologist-formulated anti-aging concentrate that targets dullness, uneven tone, and early-to-moderate lines. It suits all skin types when introduced carefully, especially those looking for clinic-level performance at home and a clean, cruelty-free formulation manufactured in the USA.
