Frequently Asked Questions
Quick answers about usage, skin comfort, formula, and expected results.
Usage
Can I use it during the day?
Yes. No.9 NAD+ Retinal Eye Cream is designed for AM and PM routines.
When using it during the day, apply sunscreen as the last step of your skincare routine.
How often should I use it?
If you are new to retinal-style skincare, start 2–3 times per week.
If your skin feels comfortable, gradually increase to daily use.
Skin Comfort
Is it suitable for sensitive skin?
The formula is designed to feel gentle, but every skin type is different.
We recommend a patch test before first use, especially if your skin is sensitive or reactive.
What should I do if my skin feels dry or uncomfortable?
Reduce frequency and use less product per application.
You can also follow with a moisturizer to support skin comfort.
Formula
What makes this different from a basic eye cream?
Basic eye creams usually focus mainly on moisture.
No.9 combines 3D Retinal, NAD+, 50 Peptides, Niacinamide, and Ceramide to support smoother, firmer, brighter-looking skin.
What is 3D Retinal?
3D Retinal refers to a retinal delivery concept designed to support stability, absorption, and daily-use comfort.
It helps make the formula feel more suitable for consistent eye-care routines.
Results
When can I expect to see results?
Some users may notice smoother-feeling skin earlier.
Visible-looking improvement usually depends on consistent use over several weeks.
Will it remove wrinkles or dark circles completely?
No skincare product can guarantee complete removal of wrinkles or dark circles.
This product is designed to help improve the look of fine lines, dullness, uneven tone, and tired-looking skin with consistent use.
