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.

No irritation/ light pleasant scent
Scent: White Peach, Size: 8oz
I use this on my fur baby once or twice a day. She’s a country girl and she likes to get muddy and smelly. Very soft, pleasant peach scent. Not overpowering. Her fur is nice and soft. Doesn’t bother her except she’s a puppy and isn’t too thrilled about me spraying stuff on her yet! 🐶🐾

Works great!!
Scent: Sweet Chamomile, Size: 8oz
I got the Sweet Chamomile scent and it is amazing!! It is a game changer for my active Goldendoodle. It not only keeps her fresh in between baths, but seems to detangle and make brushing go smother with her tight curls. I absolutely love the scent and am not a fan of overly purfymy smells.

smells amazing
Scent: White Peach, Size: 14oz
smells heavenly and even with my stinky cat, she smelled like this shampoo for a week. It makes me want to bathe her more often despite the hassle just because she smelled so heavenly. She’s a long-haired cat and brushing her after the bath was easy. I’ve never felt her hair be so soft. Since it’s just lil old her getting baths every other month, this shampoo will last me forever.

Gentle cleaning with wonderful scent
The smell is clean, sweet, and fresh. It is a gentle cleanser that I use everyday. The bottle size is convenient and easy to use. The spray bottle holds up well to constant spraying.
