Are Periodic Method products safe to use on sensitive skin?
If you are using Periodic Method skincare products for the first time, we suggest you test a small amount on the inside of your arm or underneath the angle of your jaw line to eliminate the possibility of an allergic reaction or individual sensitivity. Allow at least 24 hours to pass. If no reaction has occurred, the product should be safe for you to use. Every formula is different, and individual skin can respond differently to even carefully formulated products.
Can I use Periodic Method with my prescription skincare?
While we believe in the high quality of our formulas, everyone can respond differently. We always encourage clients to schedule a consultation with dermatologist/healthcare professional before use if you have any concerns.
