Really liked how this product helped simplify my skincare routine. I have separate products with azeliac acid, tret, niacinamide, zinc and hydroquinone which takes quite a while to layer in the mornings/evenings so definitely appreciated this was essentially a two-step process with all the ingredients I already used. I unfortunately didn’t see noticeable results and it’s way more expensive than just getting tret through a prescription that is covered by insurance. The product sizes also didn’t make sense - I ran out of the dark spot formula WAY before the future formula since it’s applied both morning at night. Super skimpy with the amount. For how expensive the product is, they should definitely make the bottles more high-end. They’re plastic and the pump doesn’t work well. Overall, meh. Won’t re-buy.
