Re: Charged water versus Fix+
^^^they actually cost the same, so one isn't more expensive than the other.
charged waters had charged ions in it, which helped the ingredients enter the skin more efficiently. each one had a different purpose, depending on the formula.
fix+ is more multi-purpose: it refreshes your skin, finishes (not sets) your makeup, tones down any overly powdery look of makeup, calms and soothes the skin (great for rashes or hot skin), and wakes up the skin (due to the caffeine!).
fix+ is what you want for what you're looking for.
