Minimize Large Pores, Regulate Sebum, and Brighten Dull Skin with Cos De BAHA Niacinamide 10 Serum (N)

Transform the texture of your skin with Cos De BAHA Niacinamide 10 Serum (N). Formulated by K-beauty experts in South Korea, this high-performance serum is engineered to tackle overactive oil production, visibly stretched pores, and uneven skin tone. Combining a powerful 10% concentration of pure Niacinamide (Vitamin B3) with 1% Zinc PCA, it effectively purifies congested pores and helps keep breakouts at bay. Instead of using a standard water base, Cos De BAHA utilizes organic Aloe Vera leaf extract to cushion the active ingredients, providing intensive hydration while significantly reducing the risk of irritation. Sourced with absolute integrity, Shei Shop brings this authentic clean beauty formula directly to skincare lovers in Bangladesh.


Key Ingredients & Their Benefits:

  • 10% Niacinamide (Vitamin B3): A gold-standard skincare ingredient that reduces the appearance of large pores, fades hyperpigmentation, smooths uneven texture, and builds a resilient skin barrier.
  • 1% Zinc PCA: Synergizes with Niacinamide to normalize sebum production, soothe red or irritated skin, and limit the factors that lead to frequent breakouts.
  • Allantoin & Licorice Root Extract: Natural botanical skin-soothers that reduce facial redness, calm inflammation, and aid in natural skin recovery.


Full Ingredient List:

Aloe Barbadensis Leaf Extract, Niacinamide (10%), Propanediol, Glycerin, 1,2-Hexanediol, Zinc PCA (1%), Sodium Hyaluronate, Allantoin, Dipotassium Glycyrrhizate, Aloe Barbadensis Leaf Extract, Camellia Sinensis Leaf Extract, Momordica Charantia Fruit Extract, Sambucus Nigra Flower Extract, Leontopodium Alpinum Extract. (Note: Ingredients are subject to change at the manufacturer's discretion. For the most complete and up-to-date list of ingredients, please refer to product packaging.)


Key Benefits:

  • Refines and Tightens Open Pores: Clears away build-up so pore walls can snap back to their natural, less visible shape.
  • Balances Excessive Oil Production: Significantly curbs midday greasy shine, especially across the forehead, nose, and chin (T-zone).
  • Fades Dark Spots & Acne Scars: Gently lightens post-inflammatory hyperpigmentation (PIH) to reveal a more uniform complexion.
  • Strengthens the Moisture Barrier: Helps skin lock in vital hydration more effectively, making it less vulnerable to environmental pollutants.
  • Clean, Vegan Formula: 100% cruelty-free and carefully manufactured without parabens, sulfates, drying alcohols, artificial colorants, or added fragrances.


Best Suited For:

  • Skin Type: Ideal for Oily, Combination, Normal, and Acne-Prone skin types.
  • Skin Concern: Large Stretched Pores, Excess Daytime Sebum, Post-Blemish Dark Marks, and Dull, Uneven Skin Discoloration.


How to Use:

  • Wash your face with a gentle cleanser and pat it completely dry.
  • Dispense 2 to 3 drops of the serum onto your fingertips or apply it directly onto your face.
  • Smooth it gently across your face and neck, then pat softly to maximize absorption.
  • Allow the serum to absorb fully for 1-2 minutes before applying your daily non-comedogenic moisturizer.
  • Usage Guide: Safe for daily use. For optimal results, apply in both your morning (AM) and night (PM) routines. Always protect your skin with a broad-spectrum high-SPF sunscreen during the daytime while using active facial serums.

Frequently Asked Questions

Answer: Yes, authenticity is our absolute priority. Every single bottle of Cos De BAHA Niacinamide 10 Serum is imported 100% genuinely through verified, official South Korean supply channels.
Answer: While Niacinamide is generally highly tolerated, a 10% strength is potent. Because this specific formulation is built on a calming Aloe Vera base rather than water, it is much gentler on the skin. However, we always recommend doing a quick 24-hour patch test behind your ear before full facial application.
Answer: Yes, modern dermatological research shows they can be used together. However, if you have easily irritated skin, it is best to use your Vitamin C serum during your morning (AM) routine and your Cos De BAHA Niacinamide Serum during your nighttime (PM) routine.
Answer: Oil control can often be noticed within the first 1 to 2 weeks of consistent daily use. Structural changes like the shrinking of stretched pores and the fading of dark acne marks typically take about 4 to 6 weeks of regular application.
