Try tatcha, their skincare line is amazing. Natural, which is good for sensitive skin, and quality is top-notch, as you would expect from a luxury japanese line.
I have combination oily skin that is sensitive. Delt with acne until my early 20s, so I understand your pain, and it finally cleared now that I'm in my mid-20s (not from growing out of it, but from finally using the right products).
I recommend tatcha's:
-Silk Cream $120 - this is better for winter, it's very moisturizing, but not too much for combination/oily skin,
-Water Cream $68 - this is all the rage right now, it's water-based, oil-free moisturizer that is somehow very hydrating. Less moisturizing than the silk cream, but perfect for very oily skin. I'm not sure why it's so much cheaper than the silk cream, but in my opinion, it's just as good.
