I've used AHC eye creams for a long time, both the purple and green lines. While other products are good, this saponin one feels the most firming, with the best absorption and hydration power!
I used to buy bundles from home shopping and use them continuously, but if you're only buying this saponin eye cream, it's on the pricier side...
Before moving on to the final cream or nourishing moisturizer step, apply this generously until it feels almost too thick, then let it absorb. You'll likely feel your under-eye area becoming more firm...
