Cos De BAHA Vitamin C 15% Serum VA 30ml

Pollution, dust, and intense humidity in Dhaka often leave skin looking dull and congested, making pores appear larger and blackheads more prominent. The Cos De BAHA Vitamin C 15% Serum VA 30ml is a high-potency Korean beauty serum designed to brighten the complexion and refine skin texture. It is an ideal choice for those struggling with uneven skin tone and environmental stress who need a lightweight, active-driven solution that doesn't feel heavy or sticky in the heat.

How does Cos De BAHA Vitamin C 15% Serum VA 30ml work?

Cos De BAHA Vitamin C 15% Serum VA 30ml is a brightening serum that uses a 15% concentration of Pure Vitamin C (Ascorbic Acid) to neutralise free radicals and support a more radiant skin tone. Pure Vitamin C works by inhibiting excess melanin production to help fade the appearance of dark spots and by promoting the look of firmer skin by supporting natural collagen processes.

Unlike oil-based serums, this water-based formula penetrates quickly, making it effective for addressing the congestion and dullness caused by urban pollution. The concentration is balanced to provide visible brightening and pore-refining benefits without the excessive irritation often found in higher percentages. By clearing away the "grey" cast that pollution leaves on the skin, it helps the complexion look fresher and more luminous.

Ideal for

• Oily and combination skin types that need brightening without added greasiness
• Skin prone to blackheads and enlarged pores caused by excess sebum and pollution
• Those with dull, tired-looking skin that lacks a natural glow
• People dealing with post-inflammatory marks or uneven skin tone from sun exposure
• Anyone looking for a potent antioxidant to protect the skin from environmental aggressors

Because this serum contains a high concentration of Pure Vitamin C, those with extremely sensitive skin or active cystic acne should patch test on the jawline first, as a slight tingling sensation is common upon application.

How to apply

1. Start with a clean face; use a gentle cleanser to remove sweat and urban grime
2. Apply 2-3 drops of Cos De BAHA Vitamin C 15% Serum VA 30ml directly to the face and neck, avoiding the immediate eye area
3. Gently pat the serum into the skin using your fingertips until fully absorbed—do not rub aggressively
4. Wait a few minutes for the serum to set before applying a moisturiser to lock in the actives
5. Apply a broad-spectrum SPF 50 sunscreen every morning—Vitamin C increases the skin's need for protection, and Bangladesh's strong UV rays can negate the brightening benefits if sunscreen is skipped

The bigger picture

Brightening and pore refinement are gradual processes, not overnight changes. When using the Cos De BAHA Vitamin C 15% Serum VA 30ml, you can expect a more refreshed look within a few weeks, while the appearance of dark spots and pore congestion typically improves after 4-8 weeks of consistent use. Since Pure Vitamin C is sensitive to light and air, keep the bottle in a cool, dark place—or even the fridge—to maintain its potency against the Dhaka heat. Consistency and sun protection are the two most important factors in seeing real results.
