Rated 5 out of 5 by from I love this product. It’s I love this product. It’s easy to use as part of my morning routine. Main tip would be: let the product dry / be absorbed by your skin for a few minutes before applying another product. If you don’t it sometimes bobbles off. It is expensive but lasts me a minimum of 3 months.
