Performing Wudu
If it is mentioned on the products you mentioned that they had anything Haram in them only then you need to bother, if not, then not. But the important thing is that pig or alcohol etc are Haram for eating only, any ingredient of them used in some product to use on body is allowed. They are not like filth. Lotion or oil are not the thing which prevent wanter to reach the body.
Okay, I will keep that in mind. JazakAllah. I asked this question above, in case you have the time to answer: “Also Dr. Irfan Shahzad, I read somewhere that someone wrote a little bit of mucus on the face does not change the nature of water. But if I have lotion all over my face or oil all over my head, wouldn’t the nature of water change based on the above logic? What are your thoughts? JazakAllah and sorry for overwhelming you with so many questions!”
