This power duo of luxurious serum and anti-aging cream is specially formulated to meet the needs of mature skin. For the Boosting Face Serum, Dr. Stefan Duve has combined two of the most effective anti-aging ingredients: Growth Factors - peptides that stimulate collagen production - and Hyaluronic Acid, which adds volume and tone to the skin. Both are also included in the Boosting Face Cream, which can be used with the serum in both the morning and evening. They provide a visibly fresher, firmer and more youthful complexion. The two products are available here as a set at an attractive special price.
