Rated 5 out of 5 by from Lovely easily absorbed cream [This review was collected as part of a promotion.] This is a lovely texture, not thick and cloying, easily absorbed and therefore lends itself to being used in conjunction with other layers.

Rated 5 out of 5 by from Such a nice gentle niacinamide [This review was collected as part of a promotion.] Such a nice gentle niacinamide serum. I only had a delux sample of this product but it felt so comfortable on the skin. I have dry dehydrated skin busy mostly very sensitive skin. This serum felt gentle and soothing on the skin and I recommended it to my daughter that has an acne prone skin, think she will enjoy this one as helping soothing and diminishing scars.
