NUMBUZIN No.5 Vitamin Concentrated Serum 30ml – Korean Brightening & Barrier Care Serum

Niacinamide, tranexamic acid, alpha-arbutin and vitamin C derivatives complement care for visible dark spots and uneven tone. Post-blemish colour marks are distinct from indented or raised scars; scar healing and treatment of pigmentation disorders are not claimed.

Panthenol and ceramide NP complement moisture-barrier care, with beta-glucan and allantoin for conditioning comfort. This does not establish guaranteed barrier repair or irritation-free use.

Glutathione and the listed vitamin C derivatives provide antioxidant conditioning alongside tone appearance care. Antioxidants do not replace sunscreen, and results vary rather than following a guaranteed timeline.

Sodium hyaluronate and tremella mushroom extract complement moisture and a softer, plumper-looking finish. Follow with moisturiser to complete the routine.

A lightweight serum described as easy to layer before moisturiser and sunscreen. Start with a small amount and let it settle; stickiness, shine and absorption vary with skin type and other products.

• Check current packaging directions and patch test before first use.
• Start two or three times weekly, increasing only if comfortable. Twice-daily use is not a required goal.
• After cleansing and optional toner, smooth a small amount over the face, avoiding eyes and damaged skin. Follow the packaging's dispensing guidance.
• Follow with moisturiser.
• Use morning or evening as tolerated. Finish daytime skincare with sunscreen.
• Introduce separately from other new products and initially keep retinoids, strong exfoliation and additional concentrated brightening treatments in different routines.

Stop for persistent stinging, burning or irritation rather than applying more product.

Normal, dry, combination or dehydrated skin seeking care for dullness, uneven-looking tone and visible post-blemish colour marks.

Sensitive or reactive skin should introduce cautiously. A multi-active serum may not suit every skin type, even with moisturising ingredients.

Choose it if you want several tone-focused ingredients and moisture support in one serum. Additional vitamin C, niacinamide or dark-spot serums are optional, not necessary additions to an already concentrated routine.

• Niacinamide: Tone appearance, visible pore care and moisture-barrier support.
• Tranexamic Acid: Complements care for visible discolouration. It is not being positioned here as an exfoliating acid.
• Alpha-Arbutin: More even-looking tone and visible discolouration care.
• Glutathione: Antioxidant conditioning.
• Vitamin C Derivatives: Radiance and antioxidant care. Exact derivative identities and concentrations are not established in the existing description; this is not a stated pure ascorbic-acid percentage.
• Panthenol and Ceramide NP: Moisturising and moisture-barrier care.
• Beta-Glucan and Allantoin: Conditioning comfort and softness.
• Sodium Hyaluronate and Tremella Mushroom Extract: Hydration and moisture-based plumping.

Refer to current packaging for the complete ingredient list. No active percentages or guaranteed gentleness are established by the word Concentrated.

Morning: Cleanser if needed → Optional toner → NUMBUZIN No.5 Serum → Moisturiser → Sunscreen.

Evening: Cleanser → Optional toner → Serum → Moisturiser.

Begin with one application on chosen days. Use retinoids or strong exfoliating treatments in separate routines initially, following their directions. More brightening layers are not automatically better.

What does it do?
It complements brighter, more even-looking tone alongside hydration and moisture-barrier care.

Is it for dark spots?
The listed tone-focused ingredients complement visible dark-spot and post-blemish colour-mark care. No outcome or treatment timeline is guaranteed.

Does it heal acne scars?
Scar healing and changes to raised or indented scars are not established. Colour marks are a different concern.

Can I use it daily?
Start two or three times weekly and increase only if tolerated and within packaging guidance.

Can I use it in the morning?
Yes, if comfortable. Follow with moisturiser and sunscreen; the serum does not provide sun protection.

Can I use it at night?
Yes, before moisturiser. Keep other strong treatments separate while assessing tolerance.

Can I use retinol or retinal?
Introduce separately and use different routines initially. Moisture support does not prevent retinoid irritation.

Is it suitable for sensitive skin?
Not universally. Patch test and introduce cautiously despite the conditioning ingredients.

Do I need another vitamin C serum?
No. Additional concentrated brightening products are optional and may add irritation without serving your routine.

Focused tone care with moisture in mind. Keep extra actives optional, introduce patiently and make daily sunscreen part of the glow routine.
