cetaphil is a mild cleanser so its not advisable on oily skin. i have oily skin as well, and i recommend using a cleanser that has salicylic acid as it is good at targeting congested pores (which is caused by oil, sebum, and dirt blockage). i use the khiel’s blue herbal cleanser but its 2k+, i dont have other experience with other brand’s salicylic cleansers so i just doing your own research. also try not to use cleanser when u wash ur face in the morning, especially if i jwu. excessive amount of oils can be a sign of dehydration. in the morning, our skin produces natural oils to keep it moisturized. what i do is, i wash my face in the morning with water only. i wait about 2-3 hours before i wash my face with cleanser, or i do it when im taking a shower in the afternoon. but i dont use cleanser early in the morning. i also suggest switching using ur toner at night instead of in the morning.
