Excess Oil and Shine

Excess Oil and Shine — the result of sebaceous glands producing more sebum than the skin needs, leaving a greasy or shiny appearance especially across the forehead, nose, and chin. Oil production is influenced by genetics, hormones, climate, and sometimes over-stripping the skin.

Key points

• Sebum is a normal and protective substance, but overproduction can lead to visible shine and contribute to clogged pores.
• Hormonal fluctuations, heat, and humidity can all increase oil production.
• Stripping the skin with harsh products may prompt it to produce even more oil in response.
• Ingredients such as niacinamide and gentle, non-comedogenic formulas can help manage the appearance of excess oil.

Frequently asked

Does oily skin still need moisturizer?

Yes, even oily skin benefits from a lightweight, non-comedogenic moisturizer, since skipping hydration can prompt the skin to produce more oil to compensate.

Can harsh cleansers make oiliness worse?

Overly harsh or drying cleansers can strip the skin's barrier and may trigger increased oil production, so gentle cleansing is generally recommended.
