Neocutis Bio Serum Firm - Hydrating and Anti-Aging Serum - 30ml

What is the difference between firm and firm riche?

I just purchased a bottle of the bio serum, i didn't realize it had been replaced with the bio serum firm. is my bio serum still effective?

Is this medical grade?

What results have you personally seen from this? How long does the bottle last? Is it worth the money? Be honest.
