numbuzin retinal eye cream No.9 — 0.67 fl oz multi-use retinal with NAD+, peptides & niacinamide for firmer, brighter under-eyes

numbuzin No.9 is a multi-use retinal eye cream that combines NAD+ and liposome-encapsulated retinal to visibly firm skin, smooth fine lines, and refine rough texture for brighter-looking under-eyes and face.

This lightweight, beginner-friendly formula brings together NAD+ (a longevity-supporting coenzyme), retinal (a potent vitamin A derivative), peptides and niacinamide to address common signs of aging and texture concerns. Designed for the delicate eye area but safe for multi-site application, the cream aims to improve the appearance of wrinkles, enlarged pores, uneven tone and "strawberry skin" texture with consistent use. The formula is clinically tested to show measurable improvement in several wrinkle types and in pore and pigmentation appearance within weeks when used as directed.

How quickly can I expect to see results around my eyes?

Clinical testing reported visible improvement in five types of eye wrinkles within four weeks when used consistently. Individual results vary by skin type and routine, but many users notice smoother texture and reduced fine lines after several weeks of nightly use.

• Clinically tested improvement in crow's feet, under-eye lines and upper eyelid wrinkles in 4 weeks.
• Expect progressive smoothing—best results after continued nightly application.
• Combine with sunscreen during daytime to protect renewed skin.

Is this retinal cream safe for beginners or sensitive skin?

numbuzin No.9 uses liposome-encapsulated retinal to enhance delivery and help minimize irritation, making it more approachable for retinal newcomers. Start with every-other-night application and gradually increase frequency as tolerance builds.

• Encapsulated retinal improves absorption while moderating potential irritation.
• Begin with low-frequency use and increase as tolerated.
• Pair with calming hydrators like niacinamide-rich serums to support barrier function.

Can I use this cream beyond the eye area?

Yes—this is a multi-use retinal treatment formulated for under-eyes, face, neck, chest and other areas prone to texture issues or aging signs. Apply sparingly to thinner areas and follow with moisturizer to maintain comfort.

• Safe for targeted application on face, neck, chest, arms, knees and elbows.
• Use a pea-sized amount for smaller zones; more for larger areas as needed.
• Always follow retinal application with daytime SPF exposure control.

What skin concerns does this product address besides wrinkles?

Beyond smoothing fine lines, numbuzin No.9 targets enlarged pores, hyperpigmentation and bumpy or rough “strawberry skin” texture. The combination of retinal, NAD+, peptides and niacinamide supports visible tone, texture and firmness improvements.

• Helps reduce the look of enlarged pores and uneven tone within weeks.
• Refines rough skin texture and diminishes the appearance of dark spots.
• Peptides and NAD+ contribute to a firmer, more resilient look over time.

Who is this for: numbuzin No.9 is aimed at anyone seeking a results-driven retinal treatment that’s gentle enough to begin using on sensitive eye areas yet versatile enough for full-face and body spot treatments. It suits beginners building tolerance to retinal, those targeting early to moderate signs of aging, and people concerned with rough texture, pores or pigmentation who want a single, clinically tested product to integrate into an evening skincare routine. Avoid use during pregnancy and consult a professional for specific medical guidance. For best outcomes, introduce gradually and protect skin from sun exposure during daytime.
