Overview of Numbuzin and Its Skincare Philosophy

Numbuzin focuses on helping you choose skincare based on your specific skin concerns rather than general categories. The brand builds its reputation on transparency, ingredient science, and a user-friendly system that simplifies your routine.

Brand Background and Vision

Numbuzin is a South Korean skincare brand that aims to make skincare more personal and straightforward. Instead of promoting one-size-fits-all solutions, it encourages you to select products that meet your skin’s unique needs.

Founded with the belief that skincare should be both effective and approachable, Numbuzin combines modern science with familiar Korean beauty principles. It avoids unnecessary marketing complexity and focuses on results that you can see and feel.

The company’s vision centres on clarity, accessibility, and trust. By designing products that are numbered and purpose-driven, Numbuzin helps you understand what each item does without confusion. This approach has made it popular among users who want reliable, easy-to-navigate skincare backed by proven formulations.

Approach to Ingredient Innovation

Numbuzin invests heavily in ingredient research and formulation technology. It uses active compounds such as peptides, ceramides, niacinamide, and NAD+ to target key skin concerns like ageing, hydration, and elasticity.

The brand often combines traditional Korean ingredients with advanced biotechnology. For example, its No. 9 NAD+ BIO Lifting-sil Essence blends NAD+, known for supporting cell repair, with 50 peptides to promote firmness and smoother texture.

You’ll notice that Numbuzin avoids unnecessary additives and focuses on balanced formulations. Many of its products are cruelty-free and suitable for sensitive skin. This scientific yet practical approach allows you to maintain healthy skin without harsh or overly complex routines.

Product Range and Numbering System

Numbuzin’s product range includes cleansers, toners, serums, essences, creams, and masks, each designed for specific functions. What sets it apart is its numbering system, which labels products by skin concern rather than by category.

For instance:

You can mix and match across numbers to build a routine that suits your skin’s changing needs. This modular system helps you shop efficiently and understand what each product contributes to your skincare goals.

Key Features of the No. 9 Bio Line

The No. 9 Bio Line focuses on anti-ageing skincare through advanced ingredients like NAD+ and peptides. It aims to improve skin elasticity, reduce visible fine lines and wrinkles, and maintain hydration with a distinctive elastic essence texture that absorbs quickly and suits various skin types.

Targeted Skin Concerns and Benefits

You can expect the No. 9 Bio Line to address visible signs of ageing such as fine lines, wrinkles, and loss of firmness. The products use NAD+, a coenzyme known for supporting skin cell repair and renewal. This helps your skin look smoother and more resilient over time.

The formula also includes 50 types of peptides that work to boost collagen production. This supports firmer, plumper skin and reduces the appearance of smile lines and frown lines.

Many users find the line beneficial for dull or fatigued skin. The blend of antioxidants, including vitamins C and E, helps protect against environmental damage that can accelerate ageing. With consistent use, your skin may appear more even-toned and refreshed.

Unique Elastic Texture and Absorption

The No. 9 Bio Lifting-sil Essence stands out for its thread-like elastic texture. When you apply it, the essence stretches slightly before melting into your skin. This texture helps the product spread evenly and ensures that active ingredients absorb efficiently.

You’ll notice that it sinks in quickly without leaving a sticky or heavy feel. This makes it suitable for both morning and evening routines, even under makeup.

The elastic formulation also enhances hydration by forming a light layer that locks in moisture. This helps maintain a soft, supple surface while improving the skin’s natural bounce.

Suitability for Different Skin Types

The No. 9 Bio Line is designed for mature and sensitive skin, but it works well for most skin types. Its lightweight texture and balanced formulation make it comfortable for dry, combination, and normal skin.

If you have sensitive skin, you’ll appreciate that the ingredients focus on strengthening the skin barrier rather than using harsh actives. The essence delivers moisture and firmness without irritation.

For oily skin, the fast-absorbing texture prevents excess shine while still providing essential hydration. You can layer it with other skincare steps without feeling greasy.

Because of its gentle yet effective formula, the No. 9 Bio Line fits easily into both simple and advanced skincare routines.

Hero Ingredients in the No. 9 NAD+ BIO Lifting-sil Essence

This essence uses a combination of cell-repairing, firming, and hydrating ingredients that support skin structure and resilience. It blends NAD+, peptides, antioxidants, and moisture-binding agents to help you maintain smoother, more elastic skin with consistent use.

NAD+ and Its Role in Skin Repair

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of your body. It helps convert nutrients into energy and supports cell repair. In skincare, NAD+ may assist in maintaining healthy skin barrier function and improving the appearance of tired or ageing skin.

When applied topically, NAD+ can help your skin’s natural renewal cycle by supporting adenosine triphosphate (ATP) production. ATP provides energy for key cellular functions such as collagen synthesis and barrier recovery.

You may notice improved firmness and texture over time as your skin becomes more efficient at repairing itself. This effect is gradual and depends on consistent use rather than instant results.

Peptide Complex and Collagen Support

The formula includes a blend of 50 peptides, short chains of amino acids that signal your skin to produce more collagen and elastin. These proteins keep your skin firm and smooth, reducing the look of fine lines and sagging.

Peptides such as acetyl hexapeptide and palmitoyl tripeptide are often used to target expression lines, while others focus on maintaining elasticity. Together, they help support your skin’s structure and improve its resilience against daily stress.

You can think of peptides as gentle messengers that remind your skin to stay active and maintain its natural strength without irritation.

Antioxidants and Skin Brightening Agents

The essence uses glutathione, vitamin C (ascorbic acid), niacinamide, and tocopherol (vitamin E) to protect your skin from oxidative stress. These antioxidants reduce the impact of environmental damage and help even out skin tone.

Niacinamide supports barrier strength and reduces dullness, while vitamin C brightens by supporting melanin balance. Glutathione works as a master antioxidant, helping to neutralise free radicals and support the effectiveness of other brightening ingredients.

This combination helps your skin look clearer and more balanced without harsh exfoliation or irritation.

Hydration and Moisture-Boosting Components

Hydration comes from sodium hyaluronate, beta-glucan, and panthenol, which attract and hold water in your skin. Sodium hyaluronate binds up to 1,000 times its weight in water, keeping your skin soft and plump.

Beta-glucan soothes irritation and supports the skin barrier, while panthenol (vitamin B5) improves moisture retention and elasticity. These ingredients work together to reduce dryness and maintain a comfortable, hydrated feel throughout the day.

Consistent hydration helps your skin better absorb active ingredients and maintain a healthy, smooth surface.

Ingredient Breakdown and Their Functions

Each formula in the Numbuzin No. 9 bio line blends structural emollients, moisture-retaining agents, and active peptides to support skin firmness and hydration. The ingredients work together to smooth texture, maintain barrier strength, and enhance product stability and shelf life.

Emollients and Texture Enhancers

Emollients soften your skin and give the serum its smooth, spreadable feel. In the No. 9 line, dimethicone, hydrogenated vegetable oil, and pentaerythrityl tetraethylhexanoate act as key texture enhancers. They form a light layer that reduces roughness and helps prevent moisture loss.

Cetearyl alcohol, glyceryl stearate, and hydrogenated lecithin also stabilise the formula. These ingredients keep oil and water components evenly mixed, improving consistency.

Fatty acids like palmitic acid and stearic acid, along with cholesterol, mimic the natural lipids in your skin barrier. This helps maintain flexibility and resilience.

Thickening agents such as carbomer, xanthan gum, and sodium polyacrylate control viscosity, giving the serum its firm yet silky texture.

Moisturisers and Humectants

Humectants attract and hold water in your skin. Glycerin, polyglycerin-3, and butylene glycol are primary moisturisers that keep your skin hydrated throughout the day. Propanediol and pentylene glycol enhance absorption and give a light, non-sticky finish.

Sodium hyaluronate and beta-glucan provide deeper hydration by binding water to skin cells. Tremella fuciformis extract, a mushroom-derived ingredient, adds a similar moisture-retaining effect.

Buffering agents like tromethamine and citric acid help maintain a balanced pH, ensuring comfort and stability. Sodium citrate supports this balance and improves product texture.

Cell-Communicating and Anti-Ageing Agents

These ingredients help your skin respond better to stress and ageing. Niacinamide supports brightening and barrier repair, while adenosine and peptide complexes encourage smoother, firmer skin.

Peptides like palmitoyl tripeptide-5 and acetyl hexapeptide-8 work to improve elasticity and reduce the look of fine lines. Cholesterol and lecithin complement these actives by strengthening the skin barrier.

You benefit from improved texture and hydration when these agents are used consistently. They don’t change your skin overnight but help maintain healthy function over time.

Preservatives and Stabilising Ingredients

Preservatives keep your product safe from bacteria and mould. Ethylhexylglycerin, chlorhexidine digluconate, and potassium sorbate act as mild yet effective protectants. They extend shelf life without adding harshness.

Stabilisers like sorbitan laurate, steareth-20, and polysorbate 20 help emulsify oils and water, preventing separation. Hydroxyethylcellulose and dextran adjust viscosity for a smooth, even texture.

Mineral salts such as magnesium chloride support formula consistency, while potassium hydroxide fine-tunes pH. These ingredients ensure each use feels the same as the first—balanced, smooth, and effective.

Clinical Results and Consumer Experience

You can expect results that focus on smoother texture, stronger elasticity, and a more radiant appearance. Users often notice visible changes in skin tone and firmness after consistent use, supported by ingredients that promote cell repair and hydration.

Visible Improvements in Wrinkles and Fine Lines

You may see a gradual softening of wrinkles and fine lines with the No. 9 NAD+ Bio Lifting-sil Essence and Face Lifting Mask. The blend of NAD+ and 50 peptides supports cell repair and collagen production, which helps restore smoother skin.

Many users report that forehead lines and smile creases appear less deep after several weeks. The essence’s peptide complex encourages new collagen formation while maintaining moisture, which can make the skin look plumper.

When used regularly, the serum and mask combination helps your skin retain elasticity and a more even surface. The results are not instant for everyone, but consistent application tends to improve visible firmness and reduce the look of ageing.

Effects on Skin Firmness and Radiance

You may notice a firmer, lifted feel after using the No. 9 sheet mask or essence. The NAD+ molecule acts as a cellular energy source, helping skin recover from stress and maintain elasticity. This process supports a more defined facial contour and a subtle, radiant inner glow.

The dissolvable PLA threads in the mask provide a tightening effect along the jawline. This helps enhance firmness temporarily while the peptides work on long-term elasticity.

Users often describe their skin as looking refreshed and slightly more sculpted after one or two uses. Over time, the consistent stimulation of collagen and elastin can make your skin feel more resilient and supple.

Texture, Absorption, and Layering in Routines

The No. 9 Essence has a thread-like, elastic texture that stretches slightly when applied. It feels thicker than most serums but absorbs quickly without leaving residue. You can apply it after toner and before moisturiser without pilling or greasiness.

Because the formula is fragrance-free and non-irritating, it suits most skin types, including dry or sensitive skin. You may find it layers well with hydrating toners, light creams, or sunscreen.

Users often describe the texture as comforting, especially in cooler weather. The serum’s balance of moisture and elasticity support makes it easy to integrate into both morning and evening routines.

How to Use the No. 9 NAD+ BIO Lifting-sil Essence for Best Results

This essence works best when applied with proper layering and consistent use. You can enhance its effects by pairing it with other numbuzin products that target hydration, repair, and firmness within the No. 9 bio line.

Application Steps and Routine Integration

Start with a clean face. Wash your skin with a gentle cleanser, then apply toner to balance pH and prepare for absorption.

Dispense 1–2 pumps of the No. 9 NAD+ BIO Lifting-sil Essence onto your fingertips. Spread evenly across your face, focusing on areas prone to wrinkles such as smile lines, forehead, and under the eyes.

Use gentle upward strokes to help the essence absorb. The formula’s NAD+, glutathione, and 50 peptides support cell repair and elasticity, so consistency is key.

Apply the essence morning and night before your moisturiser. If you use serums, layer lighter, water-based products first and follow with the essence.

Pairing with Other Numbuzin Products

You can combine this essence with other numbuzin formulas to create a balanced routine. For example, pair it with No. 3 Skin Softening Serum for improved texture or the No. 6 Deep Sleep Mask Serum for overnight nourishment.

Within the No. 9 bio line, use the NAD+ Duo set for enhanced lifting and firming benefits. The essence complements the serum in this set, helping boost collagen production and skin repair.

Avoid layering it with strong exfoliants or acids in the same routine to prevent irritation. Instead, use those on alternate days.

Finish with sunscreen during the day to protect the skin barrier and maintain the firming effects of the No. 9 NAD+ BIO Lifting-sil Essence.
