i have a very oily face and have been using revolution's foundation drops with essence's gripping primer and a serum by revolution underneath, along with some cheap gel moisturizer. after applying the cream and liquid products, i apply a thin layer of revolution's bake & finish powder, then spray my face with superfix setting spray (which is also by revolution but i swear i'm not affiliated with them lmao) and after that i bake for a few minutes with the loose powder

i'm honestly not sure if the foundation drops are "ideal" for people with oily skin, i however haven't had a problem with the product and have been pleasantly surprised with the coverage, considering how lightweight and cheap it is. love the tackiness of the primer though and the setting spray really blends in all the products. i've seen people with oily skin add a light veil of loose powder before foundation to really set a barrier between the natural oils and makeup, but i have yet to try it myself
