Sebaceous glands across the face secrete an oily substance called sebum. These glands are more common across the chin, nose and forehead, which is why people with combination skin experience an oily T-zone. Combination skin stems from an imbalance in sebum production, where the skin can produce extra oil in an attempt to protect the skin's barrier.
Weather: Weather can play a large part in this skin response. Different climates, like cold or humid air, can make it easier or harder for your skin to stay hydrated, triggering a response from your oil glands to keep the skin balanced and protected. Changes in these climates can add to the confusion.
- Stress: Lack of sleep or stress can also make combination skin more problematic since our stress hormone cortisol stimulates extra oil production.
- Harsh Skincare: Picking the right skincare for your skin is important. A lot of skincare products on the market contain stripping ingredients that may show results in the short term, but can break down your skin's moisture barrier in the long term. This will make your skin have to work even harder to keep the skin in equilibrium.
Though it may seem like the answer is to clean away the excess oil production, it is actually your skin's response to thinking it’s too dry.
