The Verdict
The numbuzin No.9 NAD+ Retinol Eye Cream is a high-performance option for those looking to target the trifecta of under-eye concerns: dark circles, puffiness, and fine lines. Its lightweight, serum-like consistency makes it an excellent candidate for daytime wear, though its potency means those with sensitive skin should approach with caution.
Who It’s For
This formula is best suited for individuals dealing with dullness and early signs of aging who want a product that layers seamlessly under makeup. If you struggle with morning puffiness, the immediate brightening effect offers a much-needed boost.
Why It Stands Out
Unlike heavy, occlusive eye creams that can cause concealer to slide or pill, this serum absorbs rapidly. The addition of a subtle, pearly shimmer provides an instant optical "wake-up" call, which users consistently report makes the eye area look more refreshed upon application.
The Downsides
While the formula is stellar, the packaging is a point of contention. The unique syringe-style applicator is intended to be precise, but many users find it cumbersome or difficult to open. Additionally, because it contains retinol, it is not for everyone. Some users noted that if too much product is applied, it can leave a white cast, and those with reactive skin may experience peeling or redness.
Final Thoughts
If you can navigate the quirky packaging, the numbuzin No.9 NAD+ Retinol Eye Cream is a sophisticated addition to a routine. Just remember to introduce it slowly to ensure your skin tolerates the active ingredients.
