[CosDeBaha] TN Tranexamic 5% Acid Niacinamide Serum 30ml
Address persistent discoloration and post-inflammatory marks with the [CosDeBaha] TN Tranexamic 5% Acid Niacinamide Serum, a 30ml treatment formulated around two of the most evidence-backed brightening compounds. This serum delivers 5% tranexamic acid alongside niacinamide to actively fade existing hyperpigmentation and block the development of new dark spots following breakouts.
The formula is engineered to decrease the skin’s sensitivity to UV rays, helping to stabilize tone while supporting daily sun exposure. Rather than depending on abrasive peeling agents, it relies on a soothing matrix of sodium hyaluronate, allantoin, betaine, and four botanical complexes—including Camellia Sinensis leaf, Sambucus Nigra flower, Momordica Charantia fruit, and Leontopodium Alpinum extract—to calm irritation and maintain hydration during correction.
Clean Formulation Standards
To address sensitive-skin concerns and minimize barrier disruption, this serum is free of eight known irritating additives, specifically excluding sulfates and mineral oils. The streamlined base allows for rapid absorption without pilling or heaviness, making it compatible with both morning serums and evening retinoid or peptide routines.
Recommended Application
Dispense a moderate amount onto cleansed skin. Gently pat the liquid into the face and neck until fully absorbed, then lock in moisture with your preferred cream or gel. Consistent daily use across the full 30ml volume supports measurable improvement in spot fading and overall radiance.

Wonderfully soothing lip balm.
The sleeping mask has a very slight and pleasant hint of strawberries, It goes on smoothly. It coats the lips with a clear balm. The lIt comes with a cute applicator. Personally I like it and would order it again.

Best Face Masks
This mask is so smooth and hydrating, without being too heavy. I have been using it nightly since I purchased and I love it. The best part is that you don't have to wash it off, it absorbs perfectly.

Shipping Policy
Shipping Policy
Do you offer free shipping?
We most certainly do! Please see the "FREE Shipping" tab below for a breakdown by Country.
When will my KBeauti order ship?
We process and ship out all orders Monday through Friday, not including holidays.
Orders with standard shipping will usually be fulfilled and shipped within 1-2 business days (Monday through Friday, not including holidays).
Please note that due to global supply chain delays, some orders may take longer than expected to reach you.
Please reach out to us at info@kbeauti.ca for further assistance.
Once your order has shipped, you will receive a shipping confirmation email with your tracking information enclosed.
Please note that it may take up to 24-48 hours for your tracking information to update.
Where will my KBeauti order ship from and how long will it take for my order to arrive?
All KBeauti orders are shipped directly from Soeul, Korea.
Orders with standard shipping usually take 10-15 business days from the day the order is placed to arrive at it's final destination.
Orders with express shipping usually take 4-7 business days from the day the order is placed.
Do you charge domestic sales tax?
Domestic sales tax will be applied to orders based on order destination and in compliance with federal, state and local laws.
Will I have to pay customs duties or import taxes?
Possibly. Orders shipped from Korea may be subject to customs duties, import taxes, VAT/GST, or brokerage fees depending on the country of delivery.
These charges are determined by your local customs authority and are not included in our product prices or shipping fees.
Who is responsible for paying these charges?
The customer is responsible for paying any duties, taxes, or import fees required by the destination country.
We do not collect or control these charges.
Why are there additional fees?
Because your order is being imported from Korea. Many countries apply duties or taxes to international shipments once they arrive in the destination country.
What about U.S. orders?
The United States currently has a de minimis threshold (generally USD $800), meaning shipments under that value may enter duty-free. However:
This threshold is set by U.S. customs and may change.
Certain products may still be assessed.
Customs has final discretion.
We are not responsible for duties assessed by U.S. customs authorities.
What happens if I refuse to pay customs charges?
If duties or taxes are not paid, the shipment may be returned or abandoned. Any return shipping, storage, or carrier fees may be deducted from your refund.
All KBeauti policies are subject to change without advanced notice.

Sunscreen & SPF Products in Canada
Sunscreen & SPF Products in Canada
Unfortunately due to regulations by Health Canada we are unable to offer any Korean sunscreen or SPF products to Canadian customers.
We are working with Health Canada to obtain Federal approval for these items, but it's a lengthy process.
We apologize for the inconvenience and will let you know as soon as this changes!
Why does my product look different from the photos on your site?
Why does my product look different from the photos on your site?
Korean beauty brands update their formulas and packaging regularly - sometimes several times a year - and these changes often happen faster than we can update every listing. We do our best to keep product pages current, but what you receive may have a newer formulation or updated packaging. The core product and its function remain the same. If you'd like to verify what's currently in stock before ordering, reach out to us at info@kbeauti.ca and we'll confirm for you.
