I've found that some of the best products out there for combination to oily skin are those that contain charcoal or some sort of clay. I find that the addition of charcoal gives me enough of the daily exfoliation that I need, without being too much. The charcoal also will soak up the excess oil that is on your face, without stripping it in a harsh way.
When I am using products that contain charcoal, I find that my skin is very smooth, bright and has an even tone. I never would have that if I used a cleanser full of chemicals or acid. Below are some of my favorite products that I've found in the past couple of years:
LUSH | Cleansing Charcoal Bar - 13.95 for 3.5 oz
I loved using this bar. You use it like you would use a bar of soap. It feels a little gritty, but it always left my face feeling very clean for the entire day. It is a little bit expensive for how much you get, especially because of how you use it. I also bought a small tin from Lush to store this in when I'm not using it. It also doesn't have an amazing smell, but I think it does the best job at cleansing. I have purchased this multiple times, and will definitely purchase it again.
FIRST AID BEAUTY | Skin Rescue Deep Cleanser with Red Clay - $24.00 for 4.7 oz
I bought this from Sephora from a recommendation from a friend. She raved about it, and I am just as excited as she was. This is a very mild, foaming cleanser that I would use in the shower. You need very little to keep your face clean and oil free. Continuous use is best, and with this cleanser, I really saw my complexion balance. Even though it is pretty expensive, it lasted me a long time. I would purchase this again.
GARNIER | Clean + Shine Control Cleansing Gel - $7.99 for 5 oz
This is the cleanser that I am currently using, and I purchased it at Walmart because I ran out of the First Aid Beauty before we went on vacation. So far it is working okay, but I think I need to use it a little more continuously before I make a solid judgement. Garnier's website says that you will see best results in one week, and that is about where I am right now. So we will see. I do notice the same effects when I first use this cleanser, but the clean face feeling doesn't last all day like the other two.
So I will continue to be on the hunt for facial cleansers that will work with my combination to oily skin. I also should note that I also moisturize daily with an oil free moisturizer. Usually a BB or a CC cream.
