The COSRX Low-pH Good Morning Cleanser is my favorite cleanser right now! It’s a very popular cleanser with lots of good reviews. If you google it, you’ll see lots reviews from other bloggers as well. I’ve read varying pH values with some people finding a value of 5.0 and others finding a value of 5.5, and and others a value of ~5.0-6.0. So know that what I found is based upon using these pH strips.
Whamisa’s deep rich toner is somewhere between a toner and an essence, I think. It seems to have a lot of positive reviews and people just love it. The instructions say to pat it on with your hands instead of using a cotton ball. This sorta implies you could use a cotton ball and use it like a toner if you wanted to. The texture, however, is a thick liquid so it is easy to apply using just your hands. A big selling point for me on this product is that it has fermented ingredients.
