[CosDeBaha] CN Serum 30ml

The [CosDeBaha] CN Serum condenses caffeine, niacinamide, and two molecular weights of hyaluronic acid into a 30ml treatment designed to brighten uneven skin tone, improve surface texture, and elevate hydration levels without leaving heavy residue.

Engineered Active Profile

Caffeine and niacinamide work in tandem to visibly lift dullness, smooth irregular textures, and target areas of inflammation and hyperpigmentation. Hydration is delivered through both sodium hyaluronate and hydrolyzed hyaluronic acid, which pull moisture into different epidermal strata to support long-term elasticity. Panthenol, allantoin, and betaine cushion the skin barrier during repeated use, while ferulic acid and a precise botanical complex—including artemisia vulgaris, melissa officinalis leaf, camellia sinensis leaf, lavandula angustifolia flower, and rosa damascena extract—add steady antioxidant and soothing coverage.

Standardized Application Routine

Dispense a moderate amount onto cleansed, dry skin
Press gently with fingertips until the liquid absorbs fully
Layer a moisturizer or sunscreen immediately after to lock in moisture

The water-aqua and butylene glycol base ensures rapid integration with subsequent skincare steps. The formula stays clear and non-greasy, making it compatible with daily morning routines or nighttime regeneration cycles without causing pilling under bases.

Direct Formulation Advantage

Instead of relying on isolated actives, this serum combines brightening, anti-inflammatory, and multi-level hydration in one transparent package. If you need a reliable topical that addresses pigment concerns and dehydration simultaneously while remaining lightweight enough for year-round layering, this 30ml bottle offers a straightforward, ingredient-driven option for consistent skin maintenance.

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.

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.

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.

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?

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.
