Cos-IQ Niacinamide Vitamin B3-20% Face Serum for Ultra Sensitive Skin

About the Product:

  • 20% 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 help regulate the amount of oil the sebaceous glands produce and avoid your glands from going into overdrive. The serum also protects against oxidative environmental stresses, such as sunlight, pollution, and toxins and removes hyperpigmentation, lightens dark & brown spots and discolouration.  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 an SPF 30+ sunscreen. Use daily (in the AM or PM) for optimal results.

Helps repair skin barrier

This stuff is amazing! It has drastically helped repair my skin barrier. I had a flare up of dermatitis right before an important event and this helped clear it!

returned- for now
Style: Updated Formula
I was using the lotion version of this for about a year, then went to the balm for more hydration. However, it seems to be breaking me out. I think because it's spring, im not needing as much occlusion as i did during winter. I'm gonna go back to the lotion formula, then pick this up again next winter. It is a little hard to spread, but I spray the avene mineral water on, let it dry slightly, and press the balm into my skin when its still wet. That helps thin the balm just enough to rub in. Otherwise, it can actually feel kind of rough!

Impressive
Style: Updated Formula
Nice thick cream! I even saw results (skin improvement) within days. I like this way better than their Cicalfate+, as it’s easier to rub in, less greasy, and doesn’t have the water vs cream separation issue. I’m not a huge fan of the pump top for this one, but at least it’s a tube instead of a solid canister (where you can’t see how much is left or get to the last bit).
