Avoid skincare products that leave your skin feeling taut and dehydrated. They cause the upper layers of the skin to shrink. This restricts oil flow through the pores leading to blockages and breakouts.
To cleanse oily skin, use oil-based products as they dissolve sebum effectively. Opt for oil-free moisturizers to maintain a shine-free complexion.

Keep your skin very clean. Limit washing your face to two or three times a day. Too much washing will stimulate your skin to produce more oil.

Take a diet rich in proteins but restricted in sugar, fluids and salt.

Take plenty of leafy green vegetables and fresh fruits.

Even a slight deficiency in vitamin B2 can cause oily skin. Nutritional yeast, wheat germ and organ meats provide both vitamin B5 and vitamin B2. Other good sources of vitamin B2 are whole grains, beans, nuts, and royal jelly. Buckwheat, black beans and whole rice are excellent to supply the body with iron and rejuvenate pate skin.

Drink plenty of quality water to keep the skin hydrated and flush out toxins.

Reduce the amount of fat in your diet. Avoid pork and fried and highly seasoned foods.
Consume no animal fats, or heat-processed vegetable oils.

Do not cook with oil. Do not eat any oils that have been subjected to heat, whether in processing or cooking. If a little oil is necessary, such as in salad dressing, use cold-pressed canola or olive oil only.

Do not drink soft drinks or alcoholic beverages. Avoid sugar, chocolate, and junk food.
