FAQ's

The numbuzin No.9 NAD Bio-lifting Serum is a high-performance anti-aging treatment designed to improve skin elasticity, reduce the appearance of wrinkles, and provide a radiant glow. Its primary benefit lies in "lifting" sagging skin and restoring facial contours by using advanced NAD technology to revitalize skin cells at a foundational level, making it ideal for those concerned with loss of firmness and dullness.

NAD (Nicotinamide Adenine Dinucleotide) is a vital coenzyme found in all living cells that plays a crucial role in energy metabolism and DNA repair. As we age, NAD levels in our skin naturally decline, leading to wrinkles and sagging. By incorporating 99% pure NAD, this serum helps "recharge" the skin's cellular energy, effectively slowing down the visible signs of aging and promoting a more youthful, resilient complexion.

Beyond its lifting properties, the No.9 Serum is formulated to provide an immediate and long-term "Bio-Glow." It works by improving skin density and hydration, which allows the skin to reflect light more evenly. The inclusion of skin-brightening components ensures that the complexion looks transparent and vibrant, helping users achieve the sought-after Korean glass skin effect.

Yes, the No.9 Serum is designed to be compatible with all skin types, including dry, oily, and sensitive skin. It has a lightweight yet nourishing texture that absorbs quickly without leaving a sticky residue. Because it focuses on cellular health and barrier support, it is particularly beneficial for those with mature skin or anyone looking to start a preventative anti-aging routine.

For the best results, apply 2-3 drops of the serum to clean, toned skin during both your morning and evening routines. Gently massage the serum in upward motions to support the lifting effect. In the morning, follow with a moisturizer and sunscreen; at night, it can be paired with the numbuzin No.9 NAD Retinol Eye Cream for an intensive overnight age-defying treatment.

While the serum is intended for full-face application to improve overall elasticity, it is highly effective when layered on areas prone to deep lines, such as the forehead, nasolabial folds (smile lines), and the neck. Its concentrated "Bio-lifting" formula helps to plump these specific areas, making fine lines less noticeable with consistent use.
