numbuzin No.9 NAD+ Retinal Volumetox Eye Cream – 20mL

numbuzin No.9 NAD+ Retinal Volumetox Eye Cream is the upgraded formula in numbuzin’s bestselling No.9 firming line, replacing standard retinol with retinal (retinaldehyde), a form of vitamin A that converts to active retinoic acid in just one step, making it faster acting on the skin. Housed in a hygienic 20mL tube that protects the light- and air-sensitive retinal, this eye cream targets the delicate under-eye area to visibly restore firmness, volume, and radiance.

This formula pairs liposome-encapsulated retinal with NAD+ (Nicotinamide Adenine Dinucleotide), a longevity-focused ingredient recognized for supporting cellular energy, alongside a 50-peptide complex, niacinamide, and ceramide NP to reinforce the skin barrier while minimizing irritation. The result is a lightweight, fast-absorbing cream built for tired, sagging, or dull under-eyes that need visible firming and brightening care.

How to Use

Apply in the evening as part of your nighttime skincare routine. Dispense a small, grain-sized amount and gently pat it around the under-eye area using your ring finger until fully absorbed, avoiding direct contact with the eyelid or lash line. If you are new to retinoids, start with 2 to 3 applications per week and gradually increase frequency as your skin builds tolerance. Always follow with sunscreen the next morning.

Who Is It For?

This eye cream is suited for anyone noticing visible signs of aging around the eyes, including fine lines, crow’s feet, sagging, or loss of volume, as well as those looking to brighten dark circles and even out under-eye tone. It is especially useful for those wanting to introduce a retinoid into their routine through a gentler, encapsulated delivery system.

Warnings

This product contains retinal, a vitamin A derivative that is more potent than standard retinol, so it should only be used at night, followed by daily sunscreen use. Avoid combining it with AHA/BHA exfoliants or vitamin C in the same routine to minimize irritation. Not recommended during pregnancy or breastfeeding. A patch test is advised before full application, and mild dryness or redness may occur during the first couple of weeks as skin adjusts.

FAQ

How is this different from the No.9 retinol eye cream? This version uses retinal instead of retinol, which converts to active retinoic acid in one step rather than two, making it faster acting.

Can I use it every day? It’s best to start with 2-3 times a week and gradually increase frequency as your skin adjusts.

Can it be used beyond the eye area? Yes, it can also be applied to smile lines, forehead lines, and other areas showing signs of aging.

Is it suitable for sensitive skin? The liposome encapsulation is designed to minimize irritation, but a patch test is still recommended for very sensitive skin.

How long does the 20mL tube last? Since only a small amount is needed per application, the generous 20mL size can last several months with consistent nightly use.
