1. Don't wash your face too often.
Washing your face twice a day is a must. Frequent washing can actually stimulate the sebaceous glands, because once the skin's surface oil is washed away, the sebaceous glands have to work overtime to perform their natural protective function. This makes the sebaceous glands increasingly irritated and overactive.
2. Don't use scrubs and astringents.
Scrubs and astringents over-stimulate the epidermis, worsening already inflamed skin and stimulating sebaceous gland secretion, making the situation worse. Furthermore, astringents can shrink pores, making already clogged pores even smaller.
3. Never pick, squeeze, or pop pimples.
Each pimple's lifespan is only 3-4 days. It will disappear naturally or come to a head when the time is up. Squeezing it with your hands or tools not only doesn't help but can also cause secondary infection due to bacteria on your hands, or cause subcutaneous bleeding due to the pressure, leaving scars that take 4-6 weeks to disappear. Furthermore, wounds caused by picking and squeezing, through repeated irritation and skin hyperplasia, can form raised scars.
4. Never smoke. Nicotine in cigarettes constricts the walls of capillaries, causing toxins to accumulate in the blood and lymph, reducing the oxygenation rate of skin cells, thus weakening the skin's healing ability and making it more susceptible to cross-infection of acne wounds.
5. Eat less spicy, fried, and high-calorie foods.While these foods do not directly cause acne, they can worsen existing acne because they increase the workload on the heart and reduce the quality of vitamin K in the blood, indirectly inducing acne formation.
