What Is Cos De BAHA Vitamin C 15% (VA) Serum?

This Korean Vitamin C serum is a high-performance brightening treatment formulated with 15% pure Ascorbic Acid. Known as one of the most effective Ascorbic Acid serum for face options on the market, it directly targets melanin overproduction to restore your skin's natural brilliance.

Key Product Details:

• Formula Type: A lightweight brightening face serum that absorbs rapidly without sticky residue.
• Skin Suitability: Ideal for dull, uneven, and mature skin types (patch test recommended for extremely sensitive skin).
• Key Active Ingredients: 15% Ascorbic Acid (Pure Vitamin C), Hyaluronic Acid, and botanical extracts.
• Core Results: Acts as the best Vitamin C serum for dark spots, significantly fading hyperpigmentation and boosting overall radiance.

Why It's Trusted (Deep E-E-A-T Protocol)

Clinical Backing & Science

Vitamin C in the form of Ascorbic Acid is the most extensively researched antioxidant in dermatology. A 15% concentration hits the "sweet spot"—powerful enough to stimulate collagen production and inhibit tyrosinase (the enzyme responsible for dark spots), yet balanced enough for daily use. Dermatological studies confirm that topical Ascorbic Acid between 10-20% offers maximal tissue absorption for anti-aging and skin brightening.

Sourcing & Quality

Every bottle sold at usmart.com.bd undergoes rigorous quality checks to ensure you receive a fresh, fully stabilized, and genuine product.

How to Use Cos De BAHA VA Serum

Step-by-Step Guide

1. Start by cleansing your face with a brightening cleanser like the Mamaearth Vitamin C Face Wash to remove impurities.
2. Pat your skin completely dry. (Never apply pure Ascorbic Acid to wet skin, as it can cause irritation).
3. Dispense 3 to 4 drops of the 15% pure Vitamin C serum into the palm of your hand.
4. Gently press and pat the serum into your face and neck, avoiding the immediate eye area.
5. Follow up with a rich moisturizer and a broad-spectrum sunscreen.

Dosage & Frequency

For best results, use this daily antioxidant face serum once a day in your morning routine. The antioxidant properties provide a second line of defense against UV damage when paired with sunscreen.

Pro-Tip

Store your serum in the refrigerator! Keeping Ascorbic Acid cold prevents it from oxidizing quickly, ensuring your serum stays clear, potent, and highly effective down to the very last drop.

Special Use Case & Results Timeline

Deep Dive: Fading Acne Scars and Dark Spots

If you need a reliable serum for acne scars and dark spots, 15% Ascorbic Acid is a powerhouse. It works by actively blocking the pathway that creates melanin in the skin, stopping dark spots from forming while breaking down existing discoloration.

Month 1

Your skin will immediately feel softer and look more radiant overall. The "dullness" begins to lift.

Month 2-3

You will notice that lighter hyperpigmentation and newer acne marks have faded significantly. Your skin tone looks remarkably more even.

Month 4+

Deep-set sun spots and older scars begin to break up and lighten. Skin elasticity improves, giving a firmer, more youthful appearance.

Potential Side Effects & Precautions

Because this is a potent 15% active, you might experience a mild, temporary tingling sensation upon application. This is normal and usually subsides within a few minutes as your skin adjusts to the low pH of the Ascorbic Acid.

Precaution: A 24-hour patch test is mandatory for new users. Apply a drop of the serum to your inner forearm or behind your ear. Wait 24 hours to ensure no severe redness, itching, or swelling occurs before applying it to your face.

Q7: Will this serum make my skin sensitive to the sun?

A: We recommend using Vitamin C in the morning and Niacinamide or Retinol at night to avoid overwhelming your skin barrier.

A: Buying from usmart.com.bd ensures you get a 100% authentic Korean product, at the best price, with reliable Cash on Delivery service right to your doorstep.
