I recently purchased Altaire Serium on a whim. After washing my face and applying the serium I instantly noticed a difference in my skin. It was silky smooth. Mind you I have combo skin (normal/dry). This serium made a huge difference in the apperance of my skin it made it feel so so smooth and I'm starting to notice my skin firming up from using it 2x's daily. I'm a firm believer in this product. Also you only use a little as it goes a long ways.
