Works great as an extra layer of hydration under my moisturizer. I get clogged pores (white heads) when I use any heavy products, but the snail mucin is nice and light. A couple heads-ups (not a dermatologist): 1) It is not an occlusive, so make sure you use a moisturizer over it. I personally use an emulsion or lightweight gel since my skin hates heavy products. 2) If you are allergic to dust mites, be wary. There can be a cross-reactivity between snail mucin and dust mites. Not guaranteed to cause a reaction, but always do a small patch test before using it over your whole face. :)
