is there an expiration date for this product?

I see none listed on the box or container. I use mine regularly and have never encountered a problem. I also buy mine ahead so they sit unused for a while and have never had an issue.

Hello! recently i bought this mask. my question is how often for a week can i use it?

This is not a mask, it’s a night cream. You use it every night before bed, and leave it on.

Which of the swiss collagen cream is good for darker skin

I don't know that it matters as to skin color. What matters is skin condition. Read the information on the jars of cream to find one suitable.
