[product question] Odacite serum with Vit C

My complexion is decent for my age (53) but a bit dull.

This routine in this article seems promising to me but I am not familiar with Odacite An Autumn on the World Vitamin C serum.

If anyone could share input/feedback/experience, I'd really appreciate it. Or if you'd recommend a similar product that would be welcome too :-)

Thanks!!
