I use the charcoal sponge, and I like how clean and soft my face feels after cleansing with it. I don't use scrubs anymore. This is a great alternative.
Ugh. I fell onto the bandwagon again.
These sponges are novel...I have three, and I have to admit washing with them is *fun...but that's all that's fun.
I tried the Pink Clay ( I bought two) and the white "natural" one from The Konjac Sponge company. At first I loved them. I thought they were really making my skin look vibrant and happy. Within a week my skin started looking dry, and I got a few deep pimples. I have not changed my cleanser, or moisturizer. I tried the Pink Clay ones without cleanser and with, same for the white one. My skin felt grimy, dry and bumpy.
Konjac is just too alkaline. I tested my wet sponge with a pH Strip. It has a pH of 7.0! Skin needs to stay at 5.5 or thereabout to retain the lipid barrier.
Fun, novel thing...but I am going back to my muslin cloths and Clarisonic 2x a week.
This sponge is a natural product made from an ancient plant that the Japanese have been using for more than 1,500 years, appearantly. Konjac is naturally alkaline and hence ideal for facial cleansing. Check out videos on youtube to see how to use.
I have discovered these sponges only a year ago and find them very reccomendable. They come in a plastic packaging that keeps them moist, but once you have used them you just hang them to dry, and simply wet them with water every time you want to reuse them...What makes these very special is the peculiar consistency of the sponge, it is very moist and soft yet also firm, so it provides the gentlest exfoliation one can imagine....I would call this a facial "buffer". It leaves my skin radiant, smooth and sqeaky clean without any drying. I simply use in the shower for a minute every morning. The price is around 8€ on zuneta.com, which I find very decent considering you can use them 3-6 months.
Only negative point I want to point out is that contrary to the claims in some videos, this sponge alone will not get rid of all makeup, particularly not the waterproof kind. I actually cleanse with a face wash before using the sponge to " buff" my face.
