Purchasing from an authorized CōTZ reseller helps to ensure that your CōTZ products are authentic, fresh and have been handled correctly.


The following online retailers are authorized to sell CōTZ products:
  • ULTA.com
  • Dermstore.com
  • Dermwarehouse
  • LovelySkin.com
  • Coolibar.com
  • PlanetBeauty.com
  • Sunprecautions.com
  • PlatinumSkinCare.com
  • Amazon.com (ONLY if “sold and shipped by Amazon”). Other 3rd party resellers on Amazon are considered unauthorized.


Unauthorized sites may carry products that are past their expiration date, spoiled, or counterfeit. These sites have no business relationship with CōTZ and do not purchase directly from us, and we can not confirm their authenticity or quality. Unauthorized retailers can pop up at any time, so the following list is not complete. If you have any question as to whether a site is authorized, please check the list above or call us with questions.
  • Walmart.com
  • Jet.com
  • eBay.com
  • Overstock.com
  • MakeupAlley.com


Diversion occurs when products are sold by unauthorized retailers. Since unauthorized retailers have no relationship with our company, we do not know where they obtained the CōTZ® they are selling and we consider these products to be diverted. Diverted products may be old, expired formulas that may not be safe to use, or may even be counterfeit. This means that if you purchase from an outlet other than our authorized retailers, we cannot guarantee that the products are authentic or that they will perform as tested.
