Numbuzin No.5+ Glutathione Vitamin Concentrated Serum

Numbuzin No.5+ Glutathione Vitamin Concentrated Serum is a concentrated brightening treatment built around high levels of niacinamide and tranexamic acid, layered with multiple vitamin C forms and glutathione. It's formulated to target dull, uneven-looking skin tone and the appearance of dark spots without alcohol, added fragrance, or essential oils.

Key Benefits

• Combines a high concentration of niacinamide with tranexamic acid to target uneven tone
• Layers multiple vitamin C forms (L-ascorbic acid and 3-O-ethyl ascorbic acid) with glutathione for antioxidant, brightening support
• Helps fade the look of dark spots and dullness over time
• Hydrates with panthenol and sodium hyaluronate
• Alcohol-free and free of added fragrance or essential oils

When to Use

Use in the morning or evening after cleansing and toner, before moisturizer. Suited to skin dealing with dullness, uneven tone, or visible dark spots.

How to Use

Dispense 2–3 drops onto clean, toned skin. Smooth over the face and neck, pat until absorbed, then follow with moisturizer (and sunscreen in the morning).

Key Ingredients

• Niacinamide (~5%): brightens and helps even the look of skin tone.
• Tranexamic Acid (~4%): targets the appearance of discoloration and supports an even tone.
• L-Ascorbic Acid & 3-O-Ethyl Ascorbic Acid (~0.2%): vitamin C forms for antioxidant and brightening support.
• Glutathione: antioxidant that supports a brighter-looking complexion.
• Panthenol (~5%): soothes and hydrates.

Precautions

Patch test before first use. The niacinamide/vitamin C combination may cause mild, temporary tingling on first use. Use daily sunscreen, as brightening actives can increase sun sensitivity. Avoid direct eye contact and discontinue use if persistent irritation occurs.
