I love how they include a little size with a spatula to scoop it out so you can mix it with their targeted serums with ease. Otherwise you are mixing in your hand which can be problematic or if you pour into the big container you can't be as sure if you got the right ratio proportions not to mention will lose the potency of the vitamin c from oxidized exposure. They said to fill the mini container 1/4 inches up with the cream then mix 5-10 drops of the VC21% serum. I love the concept! This cream is a wonderful nighttime moisturizer, don't like wearing it daytime under makeup because it's a bit thicker and my foundation doesn't set how like. However this cream is wonderful powered by 🍄! Strong anti irritation, promotes skin recovery, reduce redness and other signs of sensitive skin minimized! Hydrates, nourishes, soothe and repair damaged skin cells, increased skin elasticity, improved texture, and clarity of skin. :) #IMaxBetaGlucanCream #serumceuticals #sensitiveskin #repair #hydrating #silky #matte #notgreasy #notsticky #damagecontrol #skincarechemist #mixitup #amazon #skincare
