Glossary
A skin type characterized by excess sebum production, resulting in a shiny or greasy appearance, enlarged pores, and increased susceptibility to acne and blackheads. Oily skin is primarily determined by genetics and hormonal factors.
Oily skin occurs when sebaceous glands produce more sebum than is necessary to maintain the skin's moisture barrier. The excess oil accumulates on the skin surface, creating the characteristic shine (most prominent in the T-zone: forehead, nose, chin) and contributing to enlarged pore appearance. The pores appear larger because they are physically dilated by the volume of sebum flowing through them.
The most common mistake people with oily skin make is over-cleansing with harsh, stripping products in an attempt to remove all oil. This triggers a rebound effect: the skin detects the sudden loss of surface lipids, interprets it as a barrier emergency, and ramps up sebum production to compensate. The result is even oilier skin than before, plus a damaged moisture barrier that is now dry underneath the oil (dehydrated oily skin, one of the most frustrating skin states).
The solution is counterintuitive: gentle cleansing that removes excess oil without stripping the barrier, and lightweight moisturizing that tells the skin "the barrier is fine, reduce production." Products containing niacinamide (proven to reduce sebum production), hyaluronic acid (lightweight hydration without oil), and non-comedogenic oils like jojoba (which mimics sebum composition and may help regulate production) are the most effective strategies.
It is not all bad news. Oily skin ages more slowly than dry skin because the additional lipid layer provides natural UV protection and retains moisture better. People with oily skin in their 20s and 30s often develop fewer wrinkles and maintain skin firmness longer than their dry-skinned peers.
Yes. Oily and dehydrated are not mutually exclusive. Oily skin describes excess sebum (oil) production. Dehydration describes a lack of water in the skin. Stripping cleansers can create this combination: skin is oily on the surface but tight and uncomfortable underneath because the moisture barrier is damaged. The solution is gentle cleansing plus lightweight hydration.
Yes. Skipping moisturizer signals the skin to produce more oil. Use a lightweight, non-comedogenic moisturizer or a product containing hyaluronic acid that provides hydration without adding oiliness. Even our lighter formulations like lip balm provide barrier protection without heaviness.
