Hey there, the best product that I can think of that very is matte and gives great coverage is Revlon’s Colour Stay Matte. For really oily skin this is ideal to help avoid the shine and the reflection of light on your skin and it’s not too badly priced either. Another alternative you could also try is using a powder over your foundation to absorb any excess oils. Whe you do your cleansing routine and you are about to do your make-up right after, try using a blancing moisturizer instead of an oil-free one. A lack of oils will only encourage your own skin to continue to produce more oil so try and balance out instead of prevent all together.
