Oily skin happens when the sebaceous glands in the skin make too much sebum. Sebum is produced by the body to help keep the skin healthy, it is the waxy, oily substance that protects and hydrates the surface, but there can be too much of a good thing. Excess oil can lead to blemishes and acne flare-ups.
Oily Skin Symptoms: - a shiny or greasy appearance - very large or apparent pores on the skin - skin that looks thick or rough - occasional or persistent pimples - clogged pores and blackheads
NOTE: you can have oily skin (seborrheic skin) and can also be dehydrated, this is probably why you feel like all your moisturizer is making your skin oily.
