I mean that my face will become oily after 3 to 4 hours after application...
Mild ones or uncomfortably oily? Which Kielh's series did you use? My personal experience with Kielh, let say I apply toner+moisturiser around 8am:
- oil control series: slightly oily around 12pm, by 4pm become a bit uncomfortable.
- pore refining white clay series: slightly oily around 3pm, usually can maintain comfortness till 6 or 7pm. Somehow after used it for few months my skin becomes noticeable dry
I notice on stressful day, my skin becomes more oily, perhaps we should learn how to improve stress control instead
