This product works as advertised and provides a great base for makeup, as well as improving the appearance of blemishes. The serum really helped moisturise dry areas of skin after I'd had a cold, I could feel it working round my nose and mouth, and noticed that these areas looked and felt more healthy after use. The serum smells lovely and the bottle is small enough to pop inside your makeup bag if you're going away overnight. You don't need to used very much at a time, so a bottle should last a good amount of time before needing to be replaced.
