Core Product Details

The Art of Radiance, Perfected with Glutathione and Vitamins

Discover numbuzin No.5+ Glutathione Vitamin Concentrated Toner, an elegant Korean brightening toner designed to restore luminosity to dull, uneven-looking skin. Infused with Glutathione, Niacinamide, Vitamin C, Sea Buckthorn Water and a sophisticated blend of skin-conditioning ingredients, this essence-like formula delivers refreshing hydration while helping improve the appearance of dark spots and uneven tone.

More than a traditional toner, its moisture-rich texture prepares the complexion for subsequent skincare while enveloping the skin in antioxidant-focused care. With each application, the complexion feels refreshed, supple and beautifully conditioned, revealing a naturally luminous appearance.

Glutathione for Antioxidant-Rich Brightening Care

At the heart of numbuzin No.5+ Glutathione Vitamin Concentrated Toner is Glutathione, a naturally occurring antioxidant involved in protecting cells from oxidative stress.

Glutathione has attracted considerable interest in cosmetic skincare for its potential to support a brighter, more even-looking complexion. Research has explored its relationship with pigmentation pathways, although evidence for the effectiveness of topical Glutathione remains more limited than for several established brightening ingredients.

In this formula, Glutathione complements Niacinamide, Vitamin C and Arbutin, creating a multi-ingredient approach to improving the visible appearance of dullness and uneven skin tone.

Niacinamide for a Clearer, More Even-Looking Complexion

Niacinamide, a form of Vitamin B3, is recognized for its ability to support the skin's protective barrier and improve the appearance of uneven pigmentation, dullness and fine lines.

Its brightening benefits make it particularly appealing for skin affected by post-blemish discoloration and uneven-looking tone.

Combined with the formula's moisturizing ingredients, Niacinamide helps promote a smoother, more balanced complexion while supporting daily skin comfort.

Dual Vitamin C Complex for Luminous Skin

The toner contains two forms of Vitamin C: 3-O-Ethyl Ascorbic Acid and Ascorbic Acid.

3-O-Ethyl Ascorbic Acid is a Vitamin C derivative frequently used in cosmetic brightening formulations for its antioxidant and tone-refining potential.

Ascorbic Acid, the biologically active form of Vitamin C, is recognized for its antioxidant properties and its role in supporting collagen synthesis when delivered effectively to the skin.

Together, these ingredients complement the toner’s brightening-focused formula, helping promote a complexion that appears more radiant, refined and evenly toned.

Their effectiveness depends on concentration, formulation stability and regular use, and the individual percentages are not disclosed.

Sea Buckthorn Water for Botanical Antioxidant Care

Hippophae Rhamnoides Water, derived from Sea Buckthorn, contributes a botanical element to the toner’s antioxidant-focused skincare profile.

Sea Buckthorn is associated with naturally occurring plant compounds and has become a popular ingredient in Korean skincare designed for dull or tired-looking complexions.

Within this formula, Sea Buckthorn Water complements the Vitamin C Complex and other skin-conditioning ingredients, contributing to a refreshing and revitalizing moisturizing experience.

Arbutin for the Appearance of Dark Spots

Arbutin is a cosmetic brightening ingredient frequently used in skincare formulated for uneven pigmentation and dark spots.

It is studied for its ability to influence melanin-related pathways, making it a popular ingredient in tone-correcting skincare.

Combined with Niacinamide, Vitamin C and Glutathione, Arbutin contributes to a comprehensive approach to improving the appearance of discoloration and promoting a more even-looking complexion.

Visible improvements in dark spots generally require consistent use over time, and daily sun protection remains essential.

Nonapeptide-1 for Targeted Tone-Refining Care

Nonapeptide-1 is a synthetic peptide incorporated into some cosmetic formulations designed to improve the appearance of uneven pigmentation.

Its inclusion complements the toner’s combination of Niacinamide, Arbutin and Vitamin C, creating an additional layer of skin-conditioning care for complexions affected by dullness or uneven-looking tone.

Its individual concentration is not disclosed, and specific clinical outcomes cannot be established from ingredient presence alone.

Six-Peptide Complex for Smooth, Refined-Looking Skin

In addition to Nonapeptide-1, the toner contains Acetyl Hexapeptide-8, Hexapeptide-9, Palmitoyl Pentapeptide-4, Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7.

These peptides are commonly incorporated into anti-aging skincare for their skin-conditioning properties and potential to improve the appearance of fine lines and uneven texture.

While the toner is primarily designed for brightening and hydration, its peptide complex adds a complementary smoothing dimension to the overall formula.

Madecassoside, Bisabolol and Panthenol for Soothing Comfort

Madecassoside, a compound associated with Centella Asiatica, is valued for its soothing and skin-conditioning properties.

Bisabolol contributes additional calming care, while Panthenol, also known as Provitamin B5, helps support moisture retention and skin comfort.

Together, these ingredients complement the brightening actives, helping maintain a balanced and comfortable skin feel during regular use.

Ceramide NP for Moisture Barrier Support

Ceramide NP is a skin-identical lipid associated with the skin's natural protective barrier.

Combined with Hydrogenated Lecithin and Panthenol, it contributes to the formula's moisture-supporting properties and helps maintain a soft, supple complexion.

Its inclusion is particularly valuable in a brightening routine, where maintaining hydration and minimizing dryness can support consistent skincare use.

Glycerin and Moisture-Binding Ingredients for Essence-Like Hydration

Glycerin, Dipropylene Glycol, Butylene Glycol, Polyglycerin-3 and Erythritol form a complementary collection of moisturizing ingredients.

These humectants help attract and retain water at the skin's surface, reducing the sensation of tightness and leaving the complexion feeling refreshed and supple.

The result is a lightweight, essence-like toner that provides more than a simple refreshing step, helping prepare the skin for subsequent serums and moisturizers.

A Multi-Purpose Toner for Daily Brightening Rituals

numbuzin No.5+ Glutathione Vitamin Concentrated Toner can be incorporated into a skincare routine in several ways.

Applied with a cotton pad, it helps gently remove residual surface impurities while distributing its moisturizing formula evenly across the complexion.

Applied directly with the palms, it functions as a hydrating essence-like step, delivering a refreshing layer of moisture before serum.

Its versatile texture makes it a thoughtful choice for skincare routines focused on maintaining luminosity, hydration and an even-looking complexion.

Gentle Surface Refinement Without Harsh Exfoliation

The supplier describes this toner as suitable for gentle skin resurfacing. However, the supplied ingredient declaration does not identify a dedicated exfoliating acid at a disclosed active concentration.

Instead, its brightening ingredients, moisturizing humectants and skin-conditioning compounds help promote a smoother-looking complexion over time.

For this reason, it is best understood as a brightening and hydrating toner rather than a dedicated chemical exfoliant.

How to Use numbuzin No.5+ Glutathione Vitamin Concentrated Toner

After cleansing, dispense an appropriate amount of toner onto a clean cotton pad or directly into your palms.

For cotton-pad application, gently sweep across the face from the center outward, following the natural contours of the skin. Avoid excessive rubbing, particularly on delicate or irritated areas.

For an essence-like moisturizing application, gently press the toner into the face and neck with clean palms until absorbed.

Follow with your preferred serum and moisturizer. During the day, complete your skincare routine with broad-spectrum SPF 30 or higher.

Use once daily initially if your skin is sensitive or unfamiliar with brightening ingredients, then adjust frequency according to tolerance and manufacturer guidance.

Avoid direct contact with the eyes and application to broken skin. If using other potent brightening or exfoliating treatments, introduce products gradually to minimize the possibility of irritation.

There is a quiet luxury in a complexion that appears luminous, refined and naturally balanced. numbuzin No.5+ Glutathione Vitamin Concentrated Toner brings together the antioxidant appeal of Glutathione, the brightening potential of Vitamin C and Niacinamide, and the comforting hydration of an essence-like formula.
