Oil is naturally secreted by skin glands for important functions. It helps maintain moisture in the skin and protect it from bacteria. But sometimes, the sebaceous glands (oil producers) overwork, resulting in oil imbalance. Is your face excessively shiny? Then, you might have oily skin.

Oily skin, when touched, has a very thick texture. It has a coarse texture because pores are enlarged. When examined closely, one can see the individual pores. The skin also feels very greasy.

After you wash or take a bath in the morning, the skin will look just fine-even healthy. But during midday, it is already soaking in oil. The skin will appear shiny and greasy. High temperature and physical activities will cause the secretion of oil (dermatologically, "sebum").

Since the pores are wide open, they are prone to trapping dirt. This will cause pimples. The sebaceous glands in the T-region (forehead, nose and chin) are usually more active. These areas are more prone to acne and blackheads.

The person must not pick or pop the pimples. Bacteria can spread easily on an oily skin. Instead, use gentle soaps and cleansers, and allow the pimples to heal through time.

Teenagers and those in early twenties are prone to oily skin. The spike of hormones increases the activity of the sebaceous glands. The trend is, as people grow older, the hormones get more stable and less skin oil is produced.
