Cos-IQ Niacinamide Vitamin B3-5% Face Serum for Ultra-Sensitive Skin

About the Product:

  • 5% Niacinamide (Vitamin B3) Serum is the magic wand you've been looking for! It is a great lipid barrier builder ( a ceramide layer that helps retain moisture). It helps regulate the amount of oil the sebaceous glands produce and avaoid your glands from going into overdrive. The serum also protects against oxidative environmental stresses, such as sunlight, pollution, and toxins, and remove hyperpigmentation, lightens dark & brown spots, and discoloration.  It concurrently rebuilds healthy skin cells while also protecting them from damage caused by ultraviolet rays. It is a win-win for those looking to minimize pore appearance and blotchiness and also has wrinkles, worry lines, dullness, flare-ups, and compromised skin!
Directions to Use:
  • Clean face & neck area as per your skincare regimen. Pour 1-2 pumps on your hand & apply on dry skin with a gentle circular motion. Pat into the skin to aid absorption. A slight tingling sensation is normal. Dilute or follow up with a moisturizer if required. Always follow up with a SPF 30+ sunscreen. Use daily (in the AM or PM) for optimal results.

I’m happy with it
Size: L50 Hybrid-renewed, Size: L50 Hybrid-renewed
Works great. Edit: After a week that I wrote works great, it had the issue that when it starts cleaning it looses power and shuts off after it leave the dock. When it disengages from charging it’s dead basically so unfortunately I returned it. But I will buy it again I was happy with it.

Charging base makes awful high pitch noise.
Size: L50 Hybrid-renewed
It cleans fine but the charging base emits a terrible high pitch noise. I have to unplug it when nearby. Cats no longer want to sleep in the same room as the vacuum base. Update: A little over a year later and it appears the vacuum's onboard wifi module has passed the rainbow bridge to electric heaven. Can no longer connect the L50 to the app or local wifi. Tried resetting, reverting to older version of app, changing my wifi to 2ghz only. Trying setup in airplane mode. Nothing works.

It worked!
Set name: 10 Jumbo, Set name: 10 Jumbo
I bought this to fit a full size 4" memory foam mattress topper. I gotta say it took 3 of us. 1 to lay on the memory foam and 2 of us to get it shoved in and keep pulling the bag up. But it actually fit! My arm was dying using the hand pump so we used a vacuum. It worked better than the hand pump. Due to what I was storing it did not shrink very flat, but compared to the size of the memory foam it shrunk a lot and will definitely save space! The bags arrived today so I dont know how well it holds up long term but the bag was very sturdy yanking it up around the foam. Didn't tear or stretch. And it actually fit!

Air comes out and STAYS out!
Set name: 10 Medium
I’ve tried so many different versions of these vacuum storage bags over the years, and this company seems to have finally figured it out. They’re absolutely not exaggerating about the 80% space savings. What really impressed me is the pump design — it actually screws onto the bag, so it stays securely attached while removing the air instead of constantly slipping off. It also has a stop valve built in, which prevents air from escaping when you remove the pump to put the cap back on. Such a smart design improvement over other brands I’ve used. I bought the medium 10-pack to store my winter clothes in two 66-quart storage bins, and they fit surprisingly well. That said, part of me wishes I had also picked up a few of the smaller sizes just because they’d probably make stacking and organizing even easier. Overall though, I’m really impressed with the quality and design.

Great bags!
Set name: 10 Jumbo
These space bags are awesome! The company gives you a hand pump but your vacuum works great. They also give you tabs to slide over the ziplock part which works great. I bought the jumbo bags and I can’t believe what I was able to fit in them. More than one summer king size comforter in a bag, and 1 oversized extra large and thick king size winter comforter with shams and sheets in one bag. Other bags had several queen size quilts or comforters and decorative pillows. I highly recommend these bags. The price is great too.
