What’s Really Causing Your Oil Skin? We Found Out!

What Causes Oily Skin?

Before you start playing the blame game, let’s put your mind at ease: Having oily skin is most likely not your fault. All of our skin has sebaceous glands that produce sebum (oil) as a means of protecting our skin from external factors. Those of us with dry skin could use more sebum, and those of us with oily skin could stand to have a little less. Dr. Saxton-Daniels explains, “Oily skin is caused by increased sebum production. This can be genetic, hormonal, stress-induced, or caused by environmental factors.” 

• Genetic Factors: You can thank your parents for your active oil glands. Oily skin tends to be genetic, as even the size of your sebaceous glands is hereditary. If your skin is naturally oily, you might be tempted to up your cleansing, but Dr. Saxton-Daniels says this is a common misconception. “The genetic component of oily skin is not because people aren’t washing their face,” she clarifies. “It’s not something they can control. However, it is a treatable condition.”

• Hormones: If your skin's oiliness fluctuates at various times of the month, it could be attributed to hormonal changes. Androgens (like testosterone and estrogen) affect the way that our skin functions. With higher testosterone levels, skin tends to be oilier, while higher estrogen is associated with drier skin.

• Environment: Your skin likely behaves differently in a dry, arid climate than it does in a sticky, humid environment. Humidity tends to increase oil and sweat production, hence why you might need to reach for a mattifying primer when packing for your next tropical vacation.

• Stress: Feeling shiny before your big presentation at work? It’s not just in your head—your skin could be oily as a result of stress. When we’re under stress, our body produces cortisol (the stress hormone), which prompts our oil glands to get to work. 

How to Prevent Oily Skin

While the factors that make you more prone to oily skin might be out of your control, there are still measures you can take to manage and prevent oily skin. Dr. Saxton-Daniels says, “There is not a way to change the genetic component of oily skin…but washing your face once daily with a gentle cleanser” is a great place to start. 

Using a gentle cleanser like FIRST AID BEAUTY Pure Skin Face Cleanser is recommended, but be careful not to overwash your face. Washing your face three or more times a day in an attempt to banish excess oil can do more harm than good. Overwashing can strip your skin of essential moisture and, in turn, cause your sebaceous glands to work even harder to replace it, leading to even oilier skin.

How to Treat Oily Skin

No matter how much shine you have on your T-zone by midday, you can still benefit from a full skincare routine, including a moisturizer suitable for oily skin. Dr. Saxton-Daniels explains, “Use oil-free, non-comedogenic products, including cleansers, moisturizers, and makeup. There are also products designed to absorb and disperse oil that are safe for daily use. Look for mattifying products, as long as they are non-comedogenic.” She also recommends seeing a board-certified dermatologist for medical management of severe oily skin. She continues, “Treatment examples include topical and systemic retinoids.”

While there are many over-the-counter retinol products available that will do wonders for your skin, Dr. Saxton-Daniels highly recommends leaving the systemic retinoids to the professionals and warns against ingesting any medication without a prescription from a dermatologist.
