From the beginning of puberty, due to the increase in sex hormones in the body, the secretion of sebaceous glands increases significantly. The texture of oil is relatively viscous and is not easy to be discharged. It gradually accumulates in the mouth of hair follicles and causes blockage, so the skin becomes clogged. Small pimples bulged up, and fat particles and acne formed.

Principles of daily care for acne:
1. Make up correctly. When using cosmetics, you should make choices based on your skin condition. To avoid causing acne breakouts, avoid using oily cosmetics. Oily substances can clog pores and these foundation creams will stick to the pore walls. Many cosmetics that can cover acne well are harmful to pores. If you have to use daily cosmetics, you should choose a water-based foundation to cover acne.
2. Use disposable cotton pads. When acne breaks out on your face, use a powder puff or sponge on the area with acne. The germs on the skin surface will stick to it. When you put the powder puff back in the makeup box, the germs will start to multiply in the cosmetics. Therefore, powder should be applied using toilet paper or disposable cotton pads, and for liquid foundation, use a new cotton swab. Likewise, avoid reusing makeup brushes because the bristles can pick up fungi and bacteria in the water.
3. Reduce the duration of sunlight exposure. For people with acne on their face, a small amount of sunlight exposure will stimulate the peeling of the surface layer of the skin, while excessive sunlight exposure or heat will produce more sebum, making acne more serious. Therefore, people with acne should avoid exposure to the sun and prolonged exposure to the sun.
