I love my moisturizer and use it day and night. Recently, I read that any moisturizer containing SPF should not be worn at night because it will block the effectiveness of the ingredients. What is your opinion?
What you read is true. Any product that has a high dose of SPF will contain either titanium dioxide or zinc oxide. These are great sun blocks but they are occlusive on the skin and will prevent the other ingredients from functioning efficiently. It is also important to understand that these two ingredients will put weight on your skin at night which is believed to accentuate aging. Yikes! Our advise is to wear it only during the day when you need UV protection and find another good treatment cream formulated to benefit your skin during the night.
