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 love that this is a two pack. I keep one at the house near our entry way and the other goes out with us. Easy to apply, does not streak or leave white residue. Kept my son protected through humidity and heat in Cabo! I would def buy again.

Gentle, no-tears formula with great sun protection
Size: 6 Fl Oz (Pack of 2)
I’ve tried tons of mineral and chemical face sunscreens. Most all burn my facial skin, especially my eyelids—and make my eyes sting, too. This one, however, lives up to its “tear free” label claim beautifully. No stinging or burning whatsoever. I can wear it for the entire day with no problems. It absorbs very well into a matte finish and does not leave a cast. Feels moisturizing but not sticky on the skin. It’s creamy, but not so thick that it’s difficult to spread. And the price is a fraction of the price of many other sunscreens. I love everything about it!
