Cos-IQ Niacinamide Vitamin B3-10% Face Serum for Ultra Sensitive Skin

About the Product:

  • 10% 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 avoid 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.

34 DD approved
Color: Dark Beige, Size: 34DD
This is the first wired bra I’ve worn in years and also generally just my new favorite bra. I have breast hypertrophy and after 2 breast reductions and years of gravity, they’ll find a way to spill out of any cup and slip under any wire. The second I put this bra on I immediately felt weight off my back. The wires feel actually supportive instead of restrictive and my chest settled right into the cups smoothly and comfortably. As opposed to relying on padding (which makes me so sweaty), the construction and fabric do all the heavy lifting which makes me feel supported while still staying cool

SO very comfortable and supportive, but can't get the four hooks hooked in the back.
Color: Light Beige, Size: 44DD
I measured myself as described in listing and ordered 44dd based on that. The bra fits just right. It is super smooth and soft fabric and VERY comfortable! I especially like that it holds in the side boobs and the underwire does not poke out. I don't think I have ever had a bra before that actually stayed up on the sides! Maybe I have been wearing the wrong size?? I was skeptical and bought because of the free returns, but I am keep this one and one other style which is just as comfortable. THE ONLY THING WRONG AND THEREFORE 4 STARS is that I cannot hook the backs (4 hooks). The other one I bought was doable but with effort, this on I absolutely could not do and had to hook in the front and slide around. I don't know if there a fix for this but I will keep them because they are so dang comfy and supportive. And yes, they do minimize which is also wonderful for me!

Fits like a $100 bra
Color: Black, Size: 36H
I don’t know why HSIA bras are so comfortable. The underwire does not dig in. This is the third one I’ve purchased. This bra has a pretty lace pattern. I love it. Highly recommend.

Great bra!
Color: Dark Beige, Size: 38D
I have several different bras from this brand. This is a really good minimizer. It has a nice wide strap. I don’t love the clasp as it is covered in a hard material, but overall it is a good bra that you can wear all day under form fitting shirts.

Uncomfortable
Color: Light Beige, Size: 38DD
In my search for a comfortable well-fitting bra, I came across this one. Reviews were good, so I ordered one. Half way through the day, I had to take it off. This is the most uncomfortable bra ever. This one went on to the "uncomfortable pile" pretty quick Not full coverage and not supportive. Side coverage is pretty good but straps are thin and do not lift.
