COSRX The Niacinamide 15 Serum delivers targeted support for acne-prone skin with a clinically high 15% concentration of niacinamide, effectively reducing inflammation and regulating sebum production for a clearer complexion.

We value this serum for its precise formulation that balances potent, synergistic ingredients to enhance skin clarity and strengthen the skin’s barrier function. The lightweight texture absorbs quickly, leaving the skin feeling hydrated without any residue or heaviness, making it suitable for layering within a skincare routine.

Key Ingredients:

  • Niacinamide (15%): Reduces inflammation, minimises pores, and regulates excess sebum to control acne breakouts.
  • Acetyl Glucosamine: Promotes skin brightening and evens out skin tone by supporting natural exfoliation.
  • Zinc PCA: Helps balance oil production while providing antimicrobial properties to prevent further blemishes.

How to Use:

  1. Apply 2-3 drops to clean, dry skin after cleansing and toning.
  2. Gently pat the serum across the face, focusing on areas prone to blemishes.
  3. Follow with moisturiser and sunscreen during the day.

The Ritual Tip: For optimal results, incorporate this serum into both morning and evening routines consistently, and allow it to fully absorb before layering other products to maximise its anti-inflammatory and pore-minimising effects.

Magnets are strong
Color: E-Blackpro 4
Arrived fast. Magnets are really strong on my husbands metal peg board in the garage outside. The only draw back, the rings are slightly long for a work bench area. Wish they were 3-4''.

High Quality and Operability - Great!
Great mouse! Not only good, but feels and operates as well as, or better than a Microsoft mouse, and a lot more reasonable! Comes with AAA batteries, the USB transceiver is stored inside the battery compartment (good when packing and traveling), and a white support strap lays down below the installed batteries so that it is easier to remove them when its time to change the battery. Be sure to go into Control Panel/Mouse and make any click-speed or mouse movement adjustments to your liking. I plan on buying another one of these for my second HP laptop. The USB transceiver is immediately responsive and you will see a red laser at the bottom of the mouse.

It works and is well priced.
This mouse works as well as much higher-priced brand-name items. It fits well in the hand. The durability is very good. Considering the price compared to other brand names, this is a very good value.

Solid Everyday Mouse with a Few Comfort Trade-Offs
I’ve been using this Amazon Basics 2.4 GHz wireless optical mouse as a simple, no-frills option, and overall it does exactly what it’s supposed to do. Setup was instant with the USB nano receiver, tracking is accurate, and the wireless connection has been reliable with no dropouts or lag during daily use. It’s lightweight and works well for general browsing and office tasks. Where it falls a bit short for me is ergonomics. Compared to my Logitech mouse, this one doesn’t feel quite as natural or contoured in the hand during longer sessions. It’s by no means uncomfortable, just not as refined in terms of hand fit. That said, for the price and simplicity, it’s a dependable mouse that gets the job done. A solid choice if you want something basic and reliable.
