Niacinamide Salicylic Acid Soothing Cream Cleanser
Cosmoderm
Niacinamide Salicylic Acid Soothing Cream Cleanser
Cleanser

A traditional, heavy-lathering saponified foam wash. Because it utilizes Myristic and Stearic fatty acids reacted with Potassium Hydroxide, it has a very high, alkaline pH. Despite marketing claims targeting soothing benefits, the aggressive alkaline soap base will strip the natural acid mantle, leading to a tight, squeaky feeling. The inclusion of Niacinamide and Salicylic Acid in a rinse-off alkaline format offers limited biological contact time, while the Peppermint oil creates a cooling but sensitizing wash experience.
