Naturium is a new, affordable and efficacious skin care line available on Amazon. The vitamin C serum will work to treat dark spots and acne scars... much in the same way that Drunk Elephant C-Firma Day Serum, $80, would, but for about a quarter of the price.
These are a great dupe for Peter Thomas Roth Max Complexion Correction Pads, $46. They're just as effective and they don't burn at all. They're gentle enough to use every day for exfoliated, brighter skin.
