Laikou Switzerland Niacinamide Serum 17ml17ml

Key Ingredients

Laikou Switzerland Niacinamide Serum's primary active ingredient is Niacinamide (Vitamin B3). We want to flag an important caveat: no specific percentage concentration of Niacinamide is disclosed for this exact 17ml SKU by the brand. This product should not be confused with a separate SKU sold by the same brand, the "Laikou Pro 10% Niacinamide Brightening Serum," which does carry an explicit 10% concentration claim -- that percentage does not apply to this product. Based on a single full ingredient-panel source we located, the formula may also contain preservatives including Methylparaben and Diazolidinyl Urea, though we were not able to independently corroborate this specific preservative combination through a second source, so we present it as a single-sourced, unconfirmed detail rather than a certainty. We were unable to locate a complete, verified INCI list for this exact SKU from the brand's own official channels.

Key Features

Despite the "Switzerland" name, this product is not manufactured in Switzerland. Laikou uses country names such as Switzerland and Japan as marketing and product-line themes rather than genuine manufacturing-origin claims. The brand's actual manufacturer is Shantou Wesheda Cosmetics Co., Ltd., based in Shantou, Guangdong, China; at least one Bangladesh-based retailer has confirmed "Made in P.R.C." printed on this product line's packaging. This is a lightweight facial serum positioned around Niacinamide as a tone-evening and brightening ingredient, in a small 17ml format typical of trial or travel-sized serums.

Benefits

Niacinamide is a well-studied skincare ingredient generally associated with helping even out the appearance of skin tone, supporting the skin's barrier function, and reducing the visible appearance of enlarged pores with regular, consistent use. Because we could not confirm the exact concentration used in this SKU, we cannot make specific claims about how quickly or strongly these effects might be experienced; higher concentrations generally correlate with more pronounced (and potentially more irritating) effects, so we recommend not assuming this product matches the strength of any differently-named or differently-labeled Laikou serum.

Who Can Use This Product

Niacinamide is generally well-tolerated across most skin types, including sensitive skin, when used at typical over-the-counter concentrations. However, since the exact concentration and full ingredient panel for this SKU could not be independently confirmed, we recommend a patch test before regular use, particularly for those with reactive or sensitive skin. If the unconfirmed presence of Methylparaben and Diazolidinyl Urea is accurate, individuals with known sensitivities to parabens or formaldehyde-releasing preservatives should exercise additional caution and review the packaging closely before use.

How to Use

Apply a few drops to clean, dry skin after cleansing and toning, typically before a heavier moisturizer, as part of a morning or evening skincare routine. Gently pat or massage into the skin until absorbed. Since Niacinamide serums are commonly used with sunscreen during the day, daytime use should be paired with adequate sun protection. Always follow the specific instructions printed on the product packaging, which take precedence over this general guidance.

Storage & Safety

Store in a cool, dry place away from direct sunlight. Keep out of reach of children. Discontinue use if irritation, redness, or an allergic reaction develops, and consult a doctor if symptoms persist. Avoid contact with the eyes. Because the complete ingredient panel for this SKU could not be fully verified from the brand's own official channels, individuals with known sensitivities to preservatives or fragrance should patch-test before full use and review the product packaging carefully.

FAQ (Frequently Asked Questions)

Q: Is this serum actually made in Switzerland?

A: No. "Switzerland" is used as a marketing and product-line theme by the brand, not a genuine country-of-origin claim. The product is manufactured by Shantou Wesheda Cosmetics Co., Ltd. in China, and at least one retailer has confirmed "Made in P.R.C." on the packaging.

Q: What percentage of Niacinamide does this serum contain?

A: The brand does not disclose a specific percentage for this exact SKU. Please do not assume it matches the separately-sold "Laikou Pro 10% Niacinamide Brightening Serum," which does carry an explicit 10% claim -- that percentage is specific to that different product.

Q: Does this serum contain parabens?

A: One source we located suggests the formula may contain Methylparaben and Diazolidinyl Urea, but we could not independently confirm this through a second source, so we present it as an unconfirmed, single-sourced detail.

Q: Can I use this serum with sunscreen?

A: Yes, and we recommend it. Niacinamide serums are commonly paired with a sunscreen during daytime use as part of a complete skincare routine.

Q: Is this serum suitable for sensitive skin?

A: Niacinamide is generally well-tolerated, but since we could not fully verify this SKU's complete ingredient panel, we recommend a patch test before regular use, especially for reactive or sensitive skin.
