Thank you for reaching out to Natural Acne Clinic. :)

Here are a few tips when needing to travel light or can't use running water.

You can use Micellar Water when you don't have access to water.

You can also use face wipes, just make sure they don't have pore clogging ingredients.  

You could also bring hypochlorous acid spray.  Then apply your Mandelic in the AM and BPO in the PM.

Please let me know if you have any other questions, or concerns.

Safe travels!
