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 has the power to deliver its promises. The power ingredient here is the alguronic acid. This rebuilds skins firmness and elasticity, while restoring density. It leaves wrinkles minimized and skin radiating.  I noticed smaller pores and an overall smoothness within two weeks of use. So use Algenist day and night to get that glow…that just got some glow…
