COSRX Advanced The Vitamin C 23 Serum 20g | High-Potency 23% Pure Vitamin C & Super Vitamin E Antioxidant Brightening & Firming Glass Skin Serum | 100% Original Made in Korea
Product Overview & Benefits
Managing dark spots, post-acne blemishes, and sallow
dullness under a humid tropical climate like Bangladesh requires high-potency
antioxidant care. UV radiation and environmental pollution trigger free-radical
damage and accelerate melanin production, leading to uneven pigmentation and
loss of skin elasticity. COSRX Advanced The Vitamin C 23 Serum addresses
these core concerns by delivering a stable, maximum-strength formula that
brightens the complexion while strengthening the skin matrix.
What sets this serum apart is its High-Potency
Brightening & Antioxidant Core:
- 23%
Pure Vitamin C (Ascorbic Acid): A gold-standard antioxidant that fades
hyperpigmentation, stimulates collagen production, and restores skin
radiance.
- Super
Vitamin E (Tocotrienol): Offers up to 50 times greater antioxidant
efficacy than standard Vitamin E, working synergistically with Vitamin C
to neutralize environmental damage.
- Glutathione
& Niacinamide: Inhibits dark spot formation, clears sallow
undertones, and improves overall tone uniformity.
Supported by Sodium Hyaluronate, Squalane, Panthenol
(Vitamin B5), and Allantoin, the bi-phase formula buffers the skin
against potential active dryness. It hydrates deep tissue layers, calms
redness, and smooths surface micro-textures. Hypoallergenic and
non-comedogenic, this serum delivers noticeable clarity and a healthy glass-skin
glow.
