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.

Nice Product
Color: 2 Tier-Black, Color: 2 Tier-Black
Super Handy and So Stylish — A Must-Have for Any Kitchen! I’m really impressed with the Sinnsally Kitchen Sponge Holder! It’s simple, practical, and makes keeping my sink area neat so much easier. The 2-tier design is brilliant — the top shelf holds my sponges perfectly, while the bottom area keeps scrubbers and brushes organized and easily accessible. The stainless steel looks sleek and modern, and it has held up beautifully with daily use. Water drains well so everything dries quickly, and cleanup is a breeze. No more soggy sponges sitting around! Installation was quick and easy — it fits nicely right by the sink without taking up too much space. This little holder has made a big difference in keeping my kitchen tidy. Highly recommend for anyone who wants a clean, organized sink area with a touch of style!

Great space saver
Color: 2 Tier-Black
I love how this makes my sink so much more organized. For me, it holds a 20oz dish soap, a dish spray, 2 S.O.S. pads, 2 sponges, a steel wool scrubber, a bottle brush, a Stanley cap cleaner, and a sink stopper. I could still fit more if I wanted to. I can move the tall brush holder to whichever side I want, as well as the divider. It was super easy to put together, and functions well by draining all the drips right into my sink, instead of behind it. The black looks great and matches my kitchen well. This organized is built well and keeps mynsink area tidy and hygienic.

It Looks Nice and It Works
Color: 1 Tier-Black
I like it. It is too long for my sink area, but it still works. Next to my sink is a dish rack. One half of the caddy fits perfectly behind it, holding a 16oz bottle of dish soap and a 16oz bottle of multi-surface cleaner. The part of the caddy that fits on my sink ledge holds a sponge, scrubber and scouring pad, The caddy works great at keeping the ledge dry. It is a very nice, well-designed item. I recommend this caddy it's keeps everything organized and dry.

Good for organization, looks neat!
Color: 2 Tier-Black
I've had this for almost a year now and expect to have it for a few more; seems very durable. The drain board thingy requires consistent cleaning every few days, but its done in less than two minutes. I usually wash the entire thing every two weeks to keep it shiny as well. I am seeing a little bit of rust, but it's not too much and it's not noticeable if you don't look for it. It's great for organization and was easy to assemble. A very sturdy and well-sized product.

Serves purpose and holds what it was intended to
Color: 2 Tier-Black, Color: 2 Tier-Black
I like it. Keeps things organized and handy in small kitchen. The attachable bin holding my brushes I put on outside of unit not inside as company pics show it. That bin only has one clip to hold it in place. This makes it a little wobbly if you want to place it on the outside like I did. I used 2 trash bag twisties to help tighten it into place. Doing this made it no longer lose and the inside area space larger to hold both of my soaps. Fits everything I need it to. I appreciated the little lever on bottom that moves for water drainage. My sink design doesn’t work for the other drainage design I found these to have online.
