Johnson Test Papers – pH Indicator Strips

July 30, 2011
By

After reading about pH level test strips on one of Sesame’s blog entries, I couldn’t help but seek them out at Watsons.

A fun way to test the pH level of beauty products, each box of these universal test papers costs slightly under S$12 for 100 strips.

The pH level colour wheel determines the results. Anything below neutral 7 is acidic, while anything above 7 is alkaline. Healthy skin has a slightly acidic pH 5.5, so skincare products with this level are generally recommended to maintain dermal well-being.

This brings back memories of pottering about in chemistry labs during Science lessons in secondary school!
