I'm confused between these 2 vit C serums! Which one should I get? Share your opinions if you've used 'em ^^

The biggest concern with vitamin c serums are the packaging. Anything that has a light or see thru packaging will quickly go to waste due to the exposure of sunlight.. in this case, I would go with OST C20 as the packaging is dark enough to keep the sunlight away making it efficient and not a waste of money.
