Review (1/5): BURNS LIKE POISON
At first, I was skeptical of this product because it had no preservatives. Normally, no preservatives is good, but as anyone who's ever tried to make their own clay masks should know, clay/mud and water are notorious for being difficult to preserve "naturally" since it is highly susceptible to bacterial and fungal (mold) growth. Despite this, I bought the product because I wanted a cheap product to tide me over while I waited on materials to mix my own batch.
When I first opened the package, I immediately noticed a strong metallic smell, almost chemical in nature. I figured it COULD be some kind of metal found in the dirt, so I proceeded, though wary. I washed my face with a mild and gentle cleanser, patted it dry, mixed up the mask, and proceeded to use the brush to apply it onto my face. IMMEDIATELY, it started to burn. It burned like NOTHING I had felt before, and I regularly use AHA/BHA acids to chemically exfoliate & tone. I double checked the ingredients, and there is ABSOLUTELY NOTHING in the mask that should make it burn that way. I began to wash off the mask, but the burning sensation increased EXPONENTIALLY as I splashed water on my face to wash off the thin layer of mask that I had applied.
I can only guess that the burning is from one of two things: 1) the manufacturer lied about the ingredients or 2) the quality of the product was compromised by the fact that there were no preservatives, allowing harmful bacteria or fungus to manifest. I should note that there was no visible mold, but the fact is that you cannot determine with absolute certainty the presence or lack of bacteria/fungi in a product unless you do a microbial test, which I do not have handy.
I cannot say anything except that I would STRONGLY ADVISE AGAINST BUYING THIS MASK or any masks with similar ingredients.
