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

This concentrated 0.5 fl oz serum is formulated for targeted skin-renewal results typical of professional skincare: brighter tone, smoother texture, and reduced appearance of fine lines with regular use. MD Complete by Dr. Brian Zelickson blends a stabilized, oil-soluble vitamin C (tetrahexyldecyl ascorbate) with clinically recognized retinol and skin-friendly antioxidants, delivered through a proprietary system designed to increase absorption and maintain ingredient freshness.

How quickly will I notice changes in my skin?

Visible improvements in brightness and tone clarity can appear within 7–14 days for many users, while more pronounced smoothing and reduction in fine lines typically develop over 60–90 days with consistent application. Results depend on skin type, baseline condition, and frequency of use.

• Early radiance: improved luminosity in the first 1–2 weeks
• Texture and lines: clearer, smoother skin across 2–3 months
• Recommended consistency: nightly or as directed by your skincare professional

What active ingredients are in the formula and why they matter?

The serum combines a high-potency, oil-soluble vitamin C (tetrahexyldecyl ascorbate) with retinol, vitamin E, carotenoids, and fruit seed extracts to target tone, antioxidant protection, and cell turnover. The proprietary delivery system supports higher active-loads and improved bioavailability compared with many over-the-counter serums.

• Tetrahexyldecyl ascorbate: stable, skin-penetrating vitamin C for brightness
• Retinol: supports natural renewal to refine texture and reduce the look of fine lines
• Vitamin E + carotenoids: complementary antioxidants that support skin resilience
• Fruit seed extracts and omegas: help condition skin and reinforce formulation benefits

How should I add this serum into my skincare routine?

Introduce the concentrate gradually if you are new to retinol—start with every other night and build to nightly use as tolerated. Apply a small amount to clean, dry skin; follow with a moisturizer and daytime SPF when used in your evening regimen to protect newly resurfaced skin.

• Begin slowly: every other night for sensitive or retinol-naive skin
• Apply after cleansing, before heavier creams or oils
• Use sunscreen daily to protect treated skin from UV exposure
