Because I’ve been using Algenist Concentrated Reconstructing Serum. What I love most about this serum is its density. I find most serums to be too thick and heavy. This one is extremely thin and light, yet  still having the power to deliver its promises. The power ingredient here is the alguronic acid. This rebuilds skins firmness and elasticity, while restoring skin density, leaving wrinkles minimized and skin radiating.  I noticed smaller pores and an overall smoothness with in two weeks of use. So use Algenist day and night and get that glow, like you just had a great night ;)…..
