Could your skin be dry on the inside but oily on the outside,like mine? Actually, my face was really oily last time too. Now cos of preg, it dried up a bit. Hee
There's nothing much you can do though. Just keep it really clean. Yap clay masks help to dry up the oil a bit. Use once or twice a week. & scrub your face about once a week. Use oil-free pdts.
Previously, I use this oil control serum from Bella Skin Care. Really help but very exp. You know those kind that's really concentrated.
Maybe you could go for facials? or even see a doc to control the oil. But not recommended. Only for short term control only.
