I would highly recommend this." Another happy customer said: "I've used this product before and was really pleased with it. Leaves my sensitive skin feeling soft and nourished, a quality product that helps smooth out my wrinkles." However, not all skincare products suit everyone, as one customer noted: "Not my cup of tea. It was just another product to put on my skin. I felt 'overloaded'. Just didn't suit my skin but it may be fine for other people." Someone else knocked off a star, in a review which reads: "I love the tightening feel this product has on my face upon applying. The reason that I only gave it 4 stars is because the bottle is black, you have no idea how much product is left, and therefore don't know when to reorder."
