Clinique’s Youth Surge formula makes use of “Sirtuins technology” ( naturally occurring agents that extend the skin’s youthful look) and natural collagen boosters to provide a product that has been clinically proven to turn back the clock by 8 years in just 4 weeks of treatment! This cream is also formulated with an SPF 15 to protect your skin from the harmful rays of the sun. As with all Clinique products, this moisturizer is allergy tested and 100% fragrance free. This product is available from the Clinique counters at the Edgars stores and costs around R565,00 for a 50ml jar. Clinique really have not impressed with me with their “Youth Surge . I found that not only did this cream give my face an unpleasant shiny appearance, but it looks and feels like a suntan lotion! I also had a break-out around day 5 of using this cream.
