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.

Fav Chew Toy 🦴
Color: Blue, Color: Blue
My baby is half rottweiler and half doberman &’ he has a pretty strong grip when it comes to chew toys. But this one, it’s his favorite toy! He never leaves the house without it. It’s also really fun to add his favorite treats in there when’s he bored to keep him entertained! Not loud at all and will keep him from chewing on other things and not heavy as other rough chew toys!

Great you made super well
Color: Blue Lil Snoop, Color: Blue Lil Snoop
This is such an awesome toy. It’s super durable strong bounces and a perfect size. We got the small. We got blue because our pup can see it. It allows for creativity and endless limits to what you can make for it to be a fun experience. It has a nice sized hole in the center which allows you to add treats and food. Pop it inward and it slightly if large enough prevents the treats from coming out super fast. The ball rolls bounces and they can grip it nicely. It is easy to clean The only thing I didn’t like was the way the plastic tabs were situated inside the toy as you just be careful you don’t allow it to drip inside and dog gets it. No noise just fun. Our 15lb Cavapoo loves it

No challenge once they figure it out once, or if they have a long nose
Color: Blue
The first time I used this with my 9 month old Shepard mix, it was great. We used about 1/3 cup of her kibble and added the Nook to make it harder. It kept her working for 20-30 minutes. However, now that she knows how to remove the Nook, and stick her snout into the opening and lick up the kibble, it lasts about 5 minutes, and is no longer a challenge. She still enjoys playing with this, even when it is empty, and hasn't it destroyed it yet, so for that 3 stars.

Buy it — it’ll be your dogs best friend!
Color: Orange
Best treat toy ever! In the beginning of 2025 I bought this for my 12yr old Alaskan Malamute who loves puzzles and brain games. She loved it and played with it every day. Sadly, she passed middle of this year. Now in December, I have purchased this toy again for my newly adopted 10 month Great Dane puppy. Again, it’s an absolute hit! My Dane eats very fast, so I actually use this as a way to break up her meals. I put about half her meal (freeze dried raw kibble) in her slow feeder bowl and fill this toy about two times to feed her the other half. Also, we are crate training and before I leave the house I put treats in this toy and leave it in the crate with her. She has bad separation anxiety, but this toy actually seems to help calm her down because she enjoys it so much. I have bought many treat toys — this one is supreme. It’s not too loud or too difficult for the dogs to play with. So far it has held up without being chewed apart. It’s good quality, great size (orange for large breeds) and honestly, worth every penny.

Well made dog toy
Color: Blue
The snoops are great for our active labrador. He is a very aggressive chewer, and so far, has not destroyed a snoop yet. He has mulitples. They are a great size for filling with treats or kibble and they keep him engaged in the activity. He even likes to carry them when he does his zoomies sometimes. They are lightweight and sturdy, and the material is nice and flexible. Great toy / puzzle ball to have around for your pup!
