Hmmmm... I think that much oil means that your skin is dehydrated, so it's overprotecting with sebum? Or could be your diet? Try hydrating more, maybe that helps. I use the pore refining while I'm layering the serums and moisturizer, including oil control serum, then set it at the end (blow through a bottle really quickly, but worth it), and I can get away with not blotting for a while, or just spray some more on.
That setting spray does sound like a miracle though
I don't think it's any of the things you mentioned. I eat a healthy, balanced diet low in fat, high in fiber, and plenty of fruits and vegetables- and drink the fluids I'm supposed to drink.
My skin care routine consists of the following:
Pore Refining Toner
Oatmeal Serum and Super Serum mixed with Argan Oil (3 drops)
Intensive Moisturizer followed by the Cucumber Eye Cream
OCM for makeup removal
Lavender pH Toner
Oatmeal Serum mixed with Awesome Sauce and 4 drops of Argan Oil
Argan and Goji Berry Moisturizer followed by Cucumber Eye Cream
I exfoliate twice a week.
I feel like I'm already doing the right things as far as my skin is concerned. I spend a fair bit of change on Karen's products and don't scrimp on using it. It's just the way of things. I've always been oily, and I tend to look at the upside of that, the fact that it keeps me looking quite a bit younger.
I also use the Ultimate Luxury Powder as part of my makeup routine, and it's also a good skin treatment.
I have tried the Oil Control Serum on two different occasions for weeks at a time and felt that it didn't produce enough results for me.
