yes or no?

It depends on the question being asked.

just answer yes or no?

My apologies for any confusion. Without a specific question, I cannot provide a direct yes or no answer. Please ask a specific question, and I'll do my best to answer with a yes or no.

but the lotion or not?

I apologize for any misunderstanding, but I cannot determine if you should use lotion or not without more context or information. It depends on your personal preferences, skin type, and any specific concerns you may have. Generally, lotion can help moisturize and nourish the skin, but whether or not you should use it is a personal decision.
