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.

NOt good... not great... horrible
Set name: Sublimation Printer
I’m thoroughly disappointed with the Brother Sublimation Printer and would not recommend it. Out of the box, the setup process was more complex than anticipated, with unclear instructions and frequent errors. The print quality was inconsistent, with colors often coming out dull or inaccurate, despite multiple attempts at calibration. I experienced frequent paper jams, which disrupted my workflow and wasted a lot of materials. The printer’s software is buggy and doesn’t integrate well with other design programs, making it frustrating to use. The connectivity options were unreliable, causing frequent disconnections and delays. Additionally, the printer is quite noisy during operation, which can be distracting and bothersome. The build quality feels flimsy and not as durable as I expected. The customer support experience was also poor, with slow response times and unhelpful solutions. I faced issues with ink usage, as the cartridges seemed to run out quickly, leading to higher operational costs. The sublimation prints didn’t have the sharp, vibrant quality I was hoping for, making my final products look less professional. The lack of clear troubleshooting guides added to the frustration. The printer’s design is bulky and takes up more space than I anticipated. Overall, this Brother Sublimation Printer has been a letdown in terms of performance, reliability, and ease of use. I regret investing in this product and would advise looking for alternatives.

Pretty good for the price.
Set name: Sublimation Printer
So far so good. I have been producing a fair amount of items to date. My only wish was that the colors were more vibrant with this printer and it's ink.

Inkjets have come a long way
Pattern Name: Printer, Style: ET-15000
Just a lot to like about this printer and nothing I don't like. Very capable for the price. I do mostly black and white printing, rarely print photos. (This will supposedly do a credible job of photo printing too but I haven't tried it). If you want professional caliber photo printing, you probably want the Epson 8550 which is similar to this, a bit more expensive, but does 6 color printing. If you are doing more like every day business printing the 15000 might be a better choice because it's built more for speed. The tank system means I can just replace the black because I use it a lot. The black ink tank is double size of the others and based on my experience so far, I think I'll easily get over a thousand pages on the standard-vivid setting which is very strong black but still relatively high speed printing. Given that the black ink bottles are under $30 I think the cost per page will be comparable to laser. The booklet/pamphlet printing can be complicated to work out with layers of PDF software and the Epson printer driver. But once you work it through, it's super capable. I've printed a lot of 12 x 18 double-sided for booklets and the paper handling has been flawless. (It can duplex automatically for 8 1/2 x 11 but for other sizes you have to manually duplex, which you can do by printing back/front or even/odd.) It's not as fast as a laser printer but it's pretty fast -- inkjets have improved so much.

Perfect Printer for My Small Business
Pattern Name: Printer, Style: ET-15000
I purchased the Epson ET-15000 for my crafting and apparel business and have been very pleased with its performance. The print quality is excellent, colors are vibrant, and the large ink tanks help save money over time. It handles larger print sizes with ease and has become an essential part of my workspace.
