8 Major Causes Of Oily Skin 

Genetics strongly influence skin type. You may inherit oily skin from your parents.  

Genetics 

Hormonal changes like puberty, pregnancy, menstruation, and menopause might boost oil production. Androgens, male hormones found in both men and women, increase sebaceous gland oil production.  

Hormonal Changes 

Sebaceous glands generate sebum, which moisturizes and protects skin. These glands can overproduce oil, causing oily skin.  

Overactive Sebaceous Glands 

Hot and humid weather boosts oil production. Pollutants and contaminants can irritate the skin, causing it to overproduce oil to protect itself.  

Environmental Factors

Harsh or unsuitable skincare products can strip away natural oils, causing the skin to overproduce oil. Lack of moisturization can dehydrate oily skin, causing sebaceous glands to create more oil.  

Skincare Products 

Sugary and saturated fat-rich diets may worsen oily skin, according to several studies. A diet rich in fruits, vegetables, and whole grains may improve skin.  

Diet 

Cortisol, a stress hormone, increases oil production. Other hormonal imbalances might also cause oily skin due to stress.  

Stress 

Hormonal contraceptives, corticosteroids, and lithium can cause oily skin.
