　　COSRX snail mucin serum: Our honest thoughts I have used the COSRX Advanced Snail 96 Mucin Power Essence for about 3 months now and I use it every night after cleansing my face (and toner three times a week). I apply the essence when my skin is still damp to lock in moisture and when it’s dry, apply my final step – moisturiser. If my skin is feeling extra dry, I use a face oil after the essence and then my moisturiser, to lock it all in. So far, I can say that the snail mucin definitely delivers on its promises.

　　When I use it at night, my skin feels far more hydrated in the morning than if I leave it out of my routine. I especially like the glass finish I am left with after applying, however that doesn’t typically last till the morning.

　　Before and after ©Closer For reference, my skin type is dry and dull, and I only tend to break out the week before my period and these are often under the skin lumps. Thankfully, I haven’t noticed this product causing me any breakouts and my skin feels smooth and healthy.

　　I also really rate the bottle itself which is sleek and made from a hard plastic - handy for me as I’m clumsy and tend to knock everything over on my dressing table as I get ready. The lid is on firmly, this is great for when I’m travelling as I can take the bottle with me and not worry about it opening and ruining clothes etc. Overall I would 100% recommend, giving this product a solid five-out-of-five stars.
