However, if you have extremely sensitive skin, it's best to test the Exfoliant first. Please refer to our application instructions available on the respective product page.

Can I use the kit during pregnancy? / Are the products pregnancy safe?

Dear Moms-to-be – please make sure to discuss your skincare products and routines with your trusted gynaecologist.

Accordingly, The Exfoliant is not suitable for use during pregnancy, as chemical peels in general can reduce the skin's sensitivity to light.
