EFINITYERAuriga Vitamin C Serum 8% Flavo-C 15 mL, 0.51 us fl oz, Anti-wrinkle serum Young Skin All day

How much volumen has this ?

Am I need put on refrigerator about 24 hours before to use?

Is this supposed to be a dark amber color and smell horrible? Heard great things about the product but its hard to get past the heavy medicinal smell
