Numbuzin No.9 NAD+BIO Lifting-sil Essence

NAD+ is a coenzyme that skin cells use to produce energy, and its levels naturally decline with age, which is why it has become a popular anti-aging ingredient. In this essence, NAD+ is paired with ATP and resveratrol as the "NAD+ BIO" complex. These sit in the middle of the ingredient list, so they support the formula alongside niacinamide and adenosine.

Not automatically. What matters is which peptides are used and in what amount. In this essence, palmitoyl tripeptide-5 sits mid-list, while most of the other peptides appear at the very end in small amounts. The formula's main work comes from niacinamide, adenosine, glycerin and shea butter, with the peptide complex adding a supporting layer of care.

Not in the way a clinic treatment does. "Lifting" is part of the product name. With regular use, it helps skin look smoother, bouncier and more supple, thanks to deep hydration, adenosine for the appearance of fine lines and niacinamide for a more even-looking tone. Expect gradual improvement over several weeks rather than an instant lift.

After cleansing and toner, take an appropriate amount and apply it gently along the skin's texture, then pat lightly until absorbed, as the box recommends. Use it morning and evening, before your cream. In the morning, finish with sunscreen. It layers well under both light gel creams and richer moisturisers.

The terms overlap in Korean skincare. Essences are usually lighter, serums slightly more concentrated. This one is named an essence but described on the box as a facial serum, and it has a soft, cushioned texture thanks to shea butter and silicones. Use it as your treatment step between toner and moisturiser.

It's fragrance-free, which suits most sensitive skin, and includes calming panthenol and beta-glucan. The preservative system contains chlorhexidine digluconate, which can occasionally cause reactions, so avoid it if you know you're allergic to chlorhexidine. As with any new product, patch-test on your jawline for a few days first.

Yes. Niacinamide, adenosine and peptides pair well with both. Use a vitamin C serum such as Cos De BAHA VA in the morning, and retinol such as Celimax Retinol Shot in the evening. Apply the active first, wait a minute, then follow with this essence and your moisturiser. Always wear sunscreen during the day.

Yes. It's a simple, fragrance-free way for men to target the first fine lines, dull or tired-looking skin and dryness, all in one step. Apply after cleansing and shaving, morning and evening, then follow with moisturiser or sunscreen. Being fragrance-free, it's comfortable on freshly shaved skin.
