What is the opinion of Reddit about the
KRAVIN Collagen Serum with Natto Gum, Niacinamide, 1 fl oz?

I use this directly after Paula’s Choice BHA – I wasn’t expecting much because it’s so cheap but I’m happy with it. It has niacinamide as well as a bunch of other goodies (in microscopic quantities, ofc, I like it for that but it may be a concern if you have sensitive skin.) Let this or any other niacinamide serum sink in for a moment or two before any other steps in your routine.
