Zakia makes a very high quality clay. It is a relatively small container, but you will be able to use it for many months.A couple of things to keep in mind: Just because Ghassoul is right for me, doesn't mean it is right for you. I have very sensitive, dry skin. I moisturize obsessively throughout the day. I have very mild, occasional acne. Teenagers or anyone with severe breakouts and oily skin, may want to go straight to the Calcium Bentonite Clay. However, if you have very sensitive skin or dry skin in addition to severe acne, you may want to experiment with the Ghassoul Clay as well. Ghassoul is my favorite of the many different types of healing clays.Mix the clay with water and apply to your face or any external area you like. I don't have an exact science for the clay to water ratio, but you may try a one to one ratio to start and add more clay or water depending on how thick you want it to be. When you mix it, it will turn it into a smooth, silky paste. Put it on your skin for 5-10 minutes. If you see or feel it drying before you want to take it off, I would mist your face with water. If you know you have sensitive or dry skin, I'd try 5 minutes to make sure you don't irritate your face. Depending on the color of your skin, you may see redness, but that's normal unless it persists more than half an hour after the treatment. Ghassoul makes my skin unbelievably soft and supple. Do keep in mind that, you really should moisturize after you do a mask. I would put the mask on at night before a shower and then put on a heavy moisturizer to sleep. I like using coconut oil and Shea butter mixed together with sea buckthorn oil (especially the extremely delicate under eye skin). It will feel greasy, but it is extremely good for your skin! I promise if you use a Ghassoul Clay mask even on it's own you will see results. Smaller pores and Baby soft skin! When you pair it with a moisturizer before bed, you will wake up with the best skin you've ever had. I use it once a week as a facial/neck mask and I use it as body wash everyday. I use a coffee mug and a silicone spatula to mix it. **DO NOT USE METAL UTENSILS* Forgive, the obnoxious capital letters, but it is very important because the clay will absorb the metal and you don't want that.I love using as a body wash as well. You can do it the same way as you would mix the facial mask (one to one water to clay ratio and adjust according to your preferences) and put the mixture into a squeeze bottle. Just shake the bottle a bit to make sure it is mixed properly and then use it like you would a regular body wash. Keep in mind that it will work better if you can leave it on your skin for a minute or two. Remember, you need to use plastic without BPA because it will leech into your mixture and that would be a very bad thing. You can leave the mixture in the shower and change it once a week or so. You can also use the mixture to wash your hands as you would a regular hand soap as well. Ghassoul Clay is an amazing solution for cleaning your skin without exposing yourself to carcinogens and it will save you tons of money. I hope you all give it a try. It's worth it.
