You can use moisturizer, specifically one meant for your skin type
The only moisturizers I've ever used (I have combination oily too) were the MAC face and body lotion and Acne.org's moisturizer
MAC's moisturizer was pretty good, it didn't make me look red in the face or get oily, but Acne.org's moisturizer might not be the best for our skin type because it makes me so oily and red in the middle of the day
But did you know that using a moisturizer can actually decrease the oil your face makes?
I cleared up so much when I started using a moisturizer(the MAC one) just because my face didn't have to make extra oil for the natural oil that I lost washing from my face
Just try to get a moisturizer with no comedogenic ingredients, no oil, and no alcohol
I have my eye on Trader Joe's Antioxidant moisturizer because it has pure ingredients and it is a good price
I've tried it before, and it works good
I think that you just need to look at the labels on moisturizers, and you can find a pretty good one for cheap
So remember, make sure that it is non-comedogenic, so that you don't break out, has no alcohol, so that it doesn't make your face overly dry and red, and no oil, because you don't need more oil on your face, and you should be good to go!
Sorry that I can't offer you any specific ones, because I haven't found the perfect one for me yet
But then again, I've only tried about 3 different ones, so I have the world's worth to try before I can find the best one
Hope I helped, and good luck on your search!
