Is this mask halal?

I’ve peeked around the mediheal site, and cannot find a direct answer for you. I’d recommend emailing their help line (help@medihealcos.com) and waiting until you know for sure.

If i check from the allure.id website, the product doesn't have a halal certificate yet, so I don't know if it's halal or not, but usually Korean products if use pig collagen, they mention the origin of the collagen in the product, for example Holika Holika.

Not sure about this one, sorry 😔 Most kbeauty products don't state what kind of collagen they use so it's best to contact the brand directly if you still can't get any information about it. I usually will avoid any product with collagen if I can't find information on the source/type of collagen used stated anywhere
