    If there is any Vitamin C in the botanicals, it can react over time to form a yellowish complex with the niacinamide.  AFAIK it doesn’t change the effectiveness of either ingredient, it’s just a charge-transfer coloration

    You have so many ingredients….doing a knock-out is gonna take a while.  But I’d probably start with the one that has copper.

    Organic this, natural this and that, and then a non-approved preservative under many standards. What is your marketing?
