Snail mucin secretion from cosrx?

The use of snail mucin in cosmetics is permissible. So, yes it is halal to use. It is haram to eat snails but for external use in cosmetics or medicine, it is permissible. You may refer to this fatwa by the Mufti of Kuala Lumpur, Malaysia. There are many other articles and websites that explains this as well, you can just Google it for further information.

I’m not very sure but I have seen quite a few of my Muslim friends using these, so i think they probably are halal! There are also a few snail products from the brand coxir and jumiso

It’s halal dear

It's okayish for me, worked on my redness
