    KANOE GLOWS FROM THE INSIDE OUT WITH CAIRE

    "I love the Caire Serum & Mask, I use the serum twice a day and the mask twice a week. I noticed immediately that my skin has a glow. It feels soft and nourished. And while I love the immediate benefits, I also know that it's regenerating for my skin long term. As I'm aging, I realize that there's more than I need to do to make sure that my skin is healthy and moisturize. And I know the care beauty is doing that work in the short term and in the long term."

    Great serum

    I am 46 years old and experiences early menopause.

    Perimenopausal symptoms started around my 40 so my skin lost elasticity and firmness.

    Theorem Serum Bust makes my skin looks and feels well hydrated, rested, fresh and firmer. I tried some more expensive and well known skin brand but T.B.S works much better for me.

    I am hoping “Caire beauty” will develop their own face moisturizer to use with this serum

    Love this serum!

    I have a very dry skin and since I started using the serum, my skin has become much more moist and supple. I use the recommended amount and it is sufficient for my face, neck and chest. I'm very glad I found this product!
