Detailed answer

To determine if you have oily skin, there are a few signs to look out for. Firstly, if your skin appears shiny or greasy throughout the day, especially in the T-zone (forehead, nose, and chin), it is likely that you have oily skin. Secondly, if you have visibly enlarged pores, especially on your nose and cheeks, it can be an indication of excess oil production. Lastly, if you frequently experience breakouts, including blackheads, whiteheads, and acne, it suggests that your skin produces excess oil. These signs collectively point towards having oily skin, and it is important to choose skincare products and routines that are specifically formulated for oily skin types.
