The Supersolutions products differ from The Inkey List’s regular assembly of goods, which also contain single-ingredient options but have lower concentrations of some of the active ingredients and haven’t been formulated specifically by a team of dermatologists.
Clinical-grade skincare isn’t always the most accessible or affordable, with some brands costing up to $250 for a single product. The Supersolutions products come at a relatively low price point, but Castilla said to keep in mind that “if trying to form a skincare routine, having to buy multiple products with single ingredients versus buying one product with multiple ingredients may be more expensive in the end.”
