Many of our customers use our Tiege Hanley Skin Care or Acne Systems in conjunction with products outside our line. While we cannot guarantee what results you'll see if you use a product we did not create, you're more than welcome to incorporate that into your routine.
If you have a question about a specific product, feel free to start a chat or reach out to info@tiege.com, and we can help you with instructions on how to incorporate it into your routine.
