numbuzin No.5+ Glutathione Vitamin Concentrated Serum 30ml

Description

numbuzin No.5+ Vitamin Concentrated Serum is designed as a targeted treatment for pigmentation rather than a simple Vitamin C serum.

The formula combines several brightening ingredients that address uneven-looking pigmentation through different cosmetic pathways:

• Niacinamide supports brighter, more even-looking skin.
• Tranexamic Acid helps improve the appearance of discoloration.
• Alpha-Arbutin targets uneven pigmentation and dark spots.
• Vitamin C forms provide antioxidant and brightening support.
• Glutathione contributes additional antioxidant and tone-evening care.
• Bisabolol helps soothe and support skin comfort.

At the same time, the formula includes Panthenol, Ceramide NP, Hyaluronic Acid, Beta-Glucan, and Allantoin so the serum can deliver intensive brightening care without focusing exclusively on pigmentation.

How the Brightening Complex Works

Niacinamide – 5%

Niacinamide supports:

• More even-looking skin tone
• Brighter complexion
• Improved skin texture
• Barrier function
• Healthy-looking skin
• Reduced appearance of uneven pigmentation

Tranexamic Acid – 4%

Tranexamic Acid is included at a substantial 4% concentration and is one of the main pigmentation-focused ingredients in this formula.

It helps improve the appearance of:

• Dark spots
• Post-acne discoloration
• Uneven tone
• Areas of visible pigmentation

Alpha-Arbutin

Alpha-Arbutin complements Tranexamic Acid and Niacinamide by targeting uneven-looking pigmentation.

Vitamin C System

The formula contains multiple Vitamin C forms:

• 3-O-Ethyl Ascorbic Acid – 0.2%
• Ascorbic Acid
• Ascorbyl Glucoside

Together, they provide additional brightening and antioxidant support.

Glutathione

Glutathione is included at 100 ppm / 0.01%.

Its main role in the formula is antioxidant and tone-evening support rather than acting as the highest-concentration brightening ingredient.

Important Glutathione Concentration Clarification

The product name strongly emphasizes Glutathione, but the current Korean official ingredient disclosure lists:

Glutathione: 100 ppm = 0.01%

By comparison:

• Niacinamide = 5%
• Panthenol = 5%
• Tranexamic Acid = 4%
• 3-O-Ethyl Ascorbic Acid = 0.2%

Therefore, for scientifically accurate Infinity Skincare Solutions content, Glutathione should be presented as one part of a broader multi-active brightening system, rather than implying that Glutathione is the highest-concentration ingredient.

Antioxidant Complex

The formula includes multiple antioxidant ingredients:

• Glutathione
• 3-O-Ethyl Ascorbic Acid
• Ascorbic Acid
• Ascorbyl Glucoside
• Tocopherol
• Tocopheryl Acetate
• Ubiquinone / Coenzyme Q10
• Thioctic Acid / Alpha-Lipoic Acid
• Turmeric Root Extract

This broad antioxidant system complements the pigmentation-focused actives and helps support healthier-looking, more radiant skin.

Hydration & Barrier Support

Despite its strong brightening positioning, No.5+ Vitamin Concentrated Serum includes several ingredients focused on skin comfort.

Panthenol – 5%

Provides:

• Hydration
• Soothing support
• Barrier care
• Improved skin comfort

Ceramide NP

Helps support the natural lipid barrier and reduce moisture loss.

Sodium Hyaluronate

Helps attract water and support hydrated, plump-looking skin.

Beta-Glucan

Provides additional moisturizing and soothing support.

Allantoin + Bisabolol

Help calm and condition sensitive-looking skin.

Clinical Results

numbuzin reports clinical testing showing:

The company also states that hypoallergenic and skin-irritation testing was completed and positions the serum as suitable for sensitive and acne-prone skin.

Note: These are manufacturer-reported results under specific test conditions. Individual results will vary.

Who Is This Serum Best For?

numbuzin No.5+ Vitamin Concentrated Serum may be particularly useful for:

• Dark spots
• Post-acne marks
• Uneven skin tone
• Hyperpigmentation
• Dull-looking skin
• Acne-prone skin
• Sensitive skin seeking tone-evening care
• Combination skin
• Dry skin needing brightening plus barrier support
• Oily skin with lingering blemish marks
• Users wanting multiple brightening actives in one serum

Can Sensitive Skin Use It?

Yes, numbuzin specifically recommends the serum for sensitive skin and states that hypoallergenic and skin irritation testing has been completed.

However, individual sensitivity varies.

For reactive skin:

• Patch test before full-face use.
• Start once daily or every other day.
• Avoid applying on broken or actively irritated skin.
• Follow with moisturizer.
• Reduce frequency if persistent irritation develops.

Can Acne-Prone Skin Use It?

Yes. numbuzin includes acne-prone skin among the officially recommended skin types.

The serum may be particularly useful for the marks and discoloration remaining after blemishes, but it is not a direct acne medication.

For active inflammatory acne, dedicated acne treatments may still be required.

Ingredient Compatibility

Can You Use It with Hyaluronic Acid?

Yes. Hyaluronic Acid is compatible with this serum.

The formula already contains Sodium Hyaluronate, but additional hydrating products may be layered if needed.

Can You Use It with Niacinamide?

The serum already contains 5% Niacinamide, so an additional high-strength Niacinamide serum is usually unnecessary.

Can You Use It with Vitamin C?

The serum already contains three Vitamin C forms.

Adding a strong pure Vitamin C product in the same routine may not provide much additional benefit and can make a routine more complicated.

Can You Use It with Retinol?

Generally yes, but users with sensitive skin may prefer:

Morning: numbuzin No.5+ Serum
Evening: Retinoid

This keeps the routine simpler and may reduce irritation.

Can You Use It with AHA/BHA?

Potentially, depending on tolerance. Users with sensitive skin may prefer alternating strong exfoliating acids and this serum rather than layering everything together.

Suggested Morning Routine

Suggested Evening Routine

Important Formula-Version Clarification

Some older retailer descriptions of this product claim “60.4% Bilberry Extract” or list Vaccinium Vitis-Idaea Fruit Extract as the first ingredient.

However, numbuzin’s current Korean and global official formulas list Water first, followed by Butylene Glycol, Niacinamide, Panthenol and Tranexamic Acid. The Korean official page also discloses precise percentages for several major actives.

For current Infinity Skincare Solutions product content, it is safer to use the current official formula rather than advertise 60.4% Bilberry/Lingonberry unless your physical packaging specifically matches an older version.
