COSRX's New RX DermSerums That Sold Out Within 24 Hours!

Have you met COSRX's newest serums yet? The brand's new RX line is a line of highly-concentrated new serums, which includes The Vitamin C 23 Serum, The Niacinamide 15 Serum and The Hyaluronic Acid 3 Serum, all formulated with research-backed ingredients tailored to solve multiple skin concerns! The serums are a product of detailed analysis of consumer reviews and have been formulated with a maximum concentration of active ingredients paired with synergistic components that provide a comprehensive skin care solution.

Curious to know more about these serums, which sold out within 24 hours of its release? Read on to learn more about them!

1. COSRX The Vitamin C 23 Serum

COSRX finally created a Vitamin C serum that can be used for all skin types, including those with sensitive skin! The Vitamin C 23 serum is packed with 23% pure Vitamin C, Vitamin E, hyaluronic acid and allantoin, which helps prevent the potentially irritating effects of highly-concentrated Vitamin C. This serum promises to brighten skin and dark spots, while visibly improving fine lines.

Fun Fact! Serums with a high Vitamin C concentration are known to oxidise quickly and lose their efficacy in a short period of time. To prevent this, COSRX developed a specialised packaging method that allows the container to expel gas while blocking the inward flow of oxygen to safely house the highly concentrated pure vitamin C formula. The serum also boasts a double-layer structure with an oil layer on top to maintain freshness and delay oxidation. 

Perfect for: All skin types, especially dull, uneven skin.

2. COSRX The Niacinamide 15 Serum

COSRX created this serum as an effective all-in-one care for anyone with acne-prone skin. With a combination of ingredients perfect for those battling acne, such as Zinc PCA and niacinamide, all ingredients in this powerful serum help acne at all stages, from cause to resolution, exfoliating, soothing and clearing post acne marks for complete acne domination!

Perfect for: Oily and acne-prone skin. 

3. COSRX The Hyaluronic Acid 3 Serum 

Irrespective of the product used, hydration is the most fundamental and important benefit many people expect from their serum. Packed with 3% hyaluronic acid, which can absorb up to 1,000 times its weight in water, the Hyaluronic Acid 3 provides a plumping and hydrating effect to skin, ensuring constant hydration. Combined with NMF and ceramide, it also strengthens your skin barrier, preventing the loss of hydration. 

Perfect for: Dry, rough, dehydrated or flaky skin.

Hi Team,

I bought COSRX Niacinamide, and it barely last for over 2 weeks while i used it once in 2 days’ time. It’s a black bottle and you can’t even figure out if its full or not. I found out later that it was half a bottle. I never been so disappointed before. Being a regular customer of Nudie Glow and it was an expensive product too, I feel really bad and not sure i order now then I wont be able to trust it fully.
