Can teens use Cosrx 96 snail mucin essence ?

Yes, it should be fine. However, do patch test it first before committing it to a routine. Some people are sensitive towards snail filtrate which is the main ingredient for snail essence. You may read the 1/2 stars reviews where you can find people talking about their irritation. For a safer alternative, I recommend centella toner from corsx. Its lightweight yet hydrating enough for oily skin. If you like something with a slight thicker consistency than toner, the pyunkang yul essence is a great choice for teen skin.

teens can use any skincare. just do a patch test.

Yes, teens who have oily and acne prone skin can use it. But you can also seek for your dermatologist opinion if ever you are under medication to avoid further complications. I myself have the same skintype and I find it hydrating on the skin, it can feel tacky at times especially if you put too much but a little goes a long way and you can actually work your way up once you get the hang of it.

yes they can
