Lovely duo, the serum is nice but I prefer my CosRx Snail Essence since it helps my redness so much, but I'll still use the Neulii serum when my other runs out. I really like the cream though, it's very moisturizing and gives life back into wintery-tired skin. Stops my skin from flaking, and that's a big win! I usually use quite a lot at night, like a sleeping mask, and I wake up with the most lovely skin. It's a must try for anyone with dry, or even dehydrated, skin!
