COSRX 15% Niacinamide Face Serum - 20ml
 
Revitalize your skin with the COSRX 15% Niacinamide Face Serum, a powerful yet gentle formula designed to transform your complexion. This 20ml serum is a game - changer in your skincare routine, packed with benefits that target multiple skin concerns.
 
High - Potency Niacinamide Formula
 
At the core of this serum is 15% niacinamide, a highly effective ingredient renowned in the skincare world. Niacinamide, also known as vitamin B3, works wonders for your skin. It helps to visibly reduce the appearance of enlarged pores, making your skin texture smoother and more refined. By regulating sebum production, it's an excellent choice for those with oily or combination skin, keeping shine at bay and preventing breakouts.
 
This serum also plays a key role in brightening the skin. Niacinamide inhibits the transfer of melanin to skin cells, gradually lightening dark spots, hyperpigmentation, and uneven skin tone. Over time, you'll notice a more radiant and even - toned complexion. Additionally, it strengthens the skin barrier, improving its ability to retain moisture and protect against environmental stressors like pollution and UV damage.
 
Lightweight and Fast - Absorbing
 
The COSRX 15% Niacinamide Face Serum has a lightweight, non - greasy texture that glides onto the skin effortlessly. It absorbs quickly, leaving no sticky or oily residue behind, making it suitable for use under makeup or as part of your nighttime skincare routine. The serum is formulated to penetrate deep into the skin layers, delivering the niacinamide and other beneficial ingredients where they're needed most for maximum effectiveness.
 
Gentle and Skin - Friendly
 
Despite its high - potency formula, this serum is gentle enough for daily use. COSRX is committed to using safe and effective ingredients, and this serum is free from harsh chemicals like parabens, sulfates, and phthalates. It's suitable for a wide range of skin types, including sensitive skin. However, as with any new skincare product, it's recommended to do a patch test before full - face application.
 
How to Use
 
After cleansing and toning your face, apply 2 - 3 drops of the serum onto your fingertips. Gently pat and smooth the serum over your face and neck, avoiding the eye area. Follow up with your favorite moisturizer to lock in the benefits. For best results, use the serum both in the morning and evening as part of your regular skincare routine.

With a focus on using natural and active ingredients, COSRX creates formulas that deliver real results.

Great dog toothbrush!
Color: Blue (2-pack)
I’ve been using this product for a year now, and it’s been working great. When paired with vanilla mint enzymatic toothpaste, it effectively cleans my Pomsky’s teeth, including the back teeth. As a result, my fur baby’s teeth remain as white as ever!

Hair growth
I see results with my hair growth I'm very pleased. There is a noticeable smell to it but dissipates over a short time.

Great product, saved my hair
Honestly this is one of the best products I have ever used for my hair. I have been able to increase volume and thickness of my hair. The product is versatile and can be used in conjunction with other products as well. The application is very easy and I usually use any excess product on my skin for the added benefits. If you have fine hair your hair will get oily if you don't wash out so I just apply at night and wash out the next morning. Overall my hair is so much healthier and I am really happy I found this. Also I apply this 2-3 times per week overnight and wash in the AM. It will stain your pillow case so sleep with a bonnet or something with breathable material.
