Btw, testing over 3 months(as my message in La Prairie eye complex 3 months ago)I really like LP caviar complex and it lasts for a very long time! I only need 1/2 a drop each time, so even is expensive it works out not bad. 8 out of 10. Shame you need mosituriser on top in dry weather.Brandt is still my favorite due to price+effect together. Maybe I'll think to use cviar complex as serum then Brandt on top. 9 out of 10. Beacause it's worth the price and it's not too expensiv
