Can you return skincare products to boots?

I bought some Bulldog skin care stuff from boots the other day like scrub and moisturizer, noticed it's half price at Tesco at the moment. I have had a look on boots returns and can't see anything although my eye for small print isn't good.

Do they stop people returning things like this even if they're not used or will it be fine. (I haven't used any of it yet as I haven't run out of my current one) but there is no seal on the things either...so not sure how boots will be about it
