COSRX The Vitamin C 13 Serum 20ml | Premium 13% Pure Vitamin C (L-Ascorbic Acid), Tocotrienol & Hyaluronic Acid Brightening Serum | 100% Original Made in Korea
Product Overview & Benefits
Fading dark spots, sun discoloration, and post-acne marks
under a warm, high-humidity tropical climate like Bangladesh requires daily
active antioxidant protection that brightens skin without causing irritation or
heavy oiliness. High solar radiation, environmental pollution, and humidity
accelerate oxidative stress on skin tissue, resulting in stubborn
hyperpigmentation, sallow dullness, and early fine lines. COSRX The Vitamin
C 13 Serum addresses these core concerns by delivering a stabilized 13%
pure Vitamin C dose tailored for daily barrier-friendly use.
What lifts this brightening serum to an elite tier is its
bio-available Super Vitamin Brightening & Barrier Architecture:
- 13%
Pure Vitamin C (L-Ascorbic Acid): A clinically balanced concentration
of pure Vitamin C that inhibits melanin production, lightens post-breakout
dark marks, and stimulates structural collagen synthesis.
- Super
Vitamin E (Tocotrienol): Up to 50 times more effective than standard
Vitamin E, Tocotrienol works in synergy with Vitamin C to neutralize free
radicals, speed up tissue recovery, and stabilize the formula.
- Hyaluronic
Acid & Allantoin: Deeply hydrates thirsty cell tracks, calms skin
sensitivity, and buffers against potential tingling, making it ideal for
Vitamin C beginners and sensitive skin types.
Dermatologically tested and non-comedogenic, this liquid
serum absorbs cleanly into facial contours without leaving a heavy, sticky, or
greasy residue.

Frequently Asked Questions
Why should I store COSRX The Vitamin C 13 Serum in the
refrigerator? Pure L-Ascorbic Acid can oxidize quickly when exposed to
ambient heat and sunlight. Keeping it inside the refrigerator preserves its
potency, delays oxidation (yellowing), and provides a cooling effect during
application.
Can I use COSRX The Vitamin C 13 Serum every day?
Yes. The 13% concentration is formulated to be mild enough for daily morning
application. If you have hyper-sensitive skin, start by applying every other
day and gradually increase to daily use.
Can I use this serum alongside AHA, BHA, or Retinol?
To avoid barrier over-exfoliation, it is best to separate active steps—use
COSRX Vitamin C 13 Serum during your morning routine and save AHA/BHA or
Retinol for your evening routine.
Is this serum suitable for active acne or oily skin?
Yes. Its lightweight fluid texture absorbs rapidly into skin tracks without
clogging pores, while Vitamin C helps clear post-acne dark marks.
Where can I buy the original 20ml COSRX The Vitamin C 13
Serum in Bangladesh? You can purchase the 100% genuine COSRX The Vitamin C
13 Serum 20ml directly from our verified storefront at thealoy.com, featuring
