<human>: Can you provide a brief rundown of the text in within 3 sentences?

Ok to clarify, I am not sure whether this is a medical problem or if it is a very common ~~normality~~ occurrence. 
Basically, throughout the day, especially in the mornings and at night, I find a 'build up' of ~~dead~~ loose *skin* on the inside of my cheeks and around the inside of my lips. I constantly bite at these ~~dead~~ skin masses until I rid my cheeks of them. 
The same, yet not as flimsy, build up occurs on the tips of my nails around my fingernails. It is most noticeable during a shower when my hands get moist *like the inside of my cheeks*. 
The skin appears white, almost transparent, and is constantly building up in these locations, hence why I bite them off. 
So my question to you redditors is, does anybody else experience this?
<bot>: I have dead skin building up in my cheeks and on my fingers and I bite it off. Is this normal for anyone else?
