Our take
Is Nannochloropsis Oculata Extract a Good Ingredient?
The evidence for lasting firming is limited and the tightening effect is mostly short-lived, with antioxidant support based largely on in-vitro data, which is why it rates Fair. Very sensitive skin may experience mild, temporary irritation.
