Do not use this in the washer and/or the dryer (no dryer sheets). The waxy residue gets on your pillowcases, towels, wash cloths, and sheets that have direct contact with the skin. The residue will clog pores of acne-prone individuals. If you want something to stop static cling in your dryer, you can get anti- static balls at Bed Bath and Beyond, Target, or online.
Detergents with fragrance can cause skin irritation. Best to use fragrance-free such as Cheer Free, All Free & Clear, Tide Free, and Arm & Hammer Free.
No Water Softeners
There is some evidence that water softeners can lead to acne, especially those containing high amounts of potassium chloride.
