Every Summer for the past few years, this serum has been my number 1 go to product to give me that radiance that only a Caviar Gold Serum can offer. As the name suggests it contains Caviar Extract, real Gold Particles (Colloidal Gold) as well as Cucumber Extract. The tiny flecks of gold in the product give your skin an instant glow whilst the caviar extract luxuriously feeds your skin with vitamins and nutrients. What i like about this serum is that it is extremely light weight which makes it perfect to wear under makeup in hot weather. It wont clog your pores or break you out.
