Oily skin happens mainly because of overactive sebaceous glands. These glands, found under your pores, naturally produce an oily substance called sebum. Sebum itself is important — it keeps skin moisturized and forms a protective barrier — but when too much is produced, it leads to shine, clogged pores, and sometimes acne.

Here are the main reasons why skin becomes oily:

Genetics

If oily skin runs in your family, your sebaceous glands are naturally more active.

Hormones

Fluctuations in hormones — especially androgens — increase sebum production. This is why oily skin is common during puberty, menstruation, pregnancy, or hormonal imbalances.

Climate & Environment

Hot, humid weather: skin produces more oil.

Cold, dry air: skin may get dehydrated, prompting glands to overproduce oil to compensate.

Skincare Habits

Using harsh cleansers or overwashing can strip skin, making glands produce even more oil.

Skipping moisturizer can trick your skin into thinking it’s dry, again increasing sebum output.

Diet & Lifestyle

High glycemic foods (sugary, processed carbs) and excessive dairy sometimes worsen oiliness. Stress boosts cortisol, which can trigger more oil.

In short: Oily skin is mostly about overproduction of sebum due to genetics, hormones, and lifestyle/environmental factors.
