First, the reason:
1, cosmetics contain chemical components, but more or less there are harmful substances, which will irritate human skin. For example, depigmented cosmetic preparations contain toxic chemicals such as inorganic mercury salts and hydroquinone, which are potentially harmful to human body after long-term use.
2, some cosmetics, in order to highlight the effect of cosmetics, drugs such as antibiotics will be added, which will make the skin become very good for a period of time, but long-term use of the skin will produce dependence, causing inflammatory skin diseases on the face or other makeup parts.
3. In hot summer, most of the capillaries in the whole body are open, and the blood circulation in the whole body is accelerated, which will increase the absorption of harmful chemicals and easily poison cosmetics.
4, long-term lipstick will also affect the overall health. Lanolin and wax in lipstick have strong adsorbability, which often adsorb dust, bacteria, viruses and some heavy metal ions in the air on the oral mucosa, which not only increases the probability of causing allergies, but also easily brings lipstick and harmful substances attached to it into the oral cavity when drinking water and eating, which is harmful to the body.
Second, the solution:
1, makeup must be removed, and makeup removal is particularly important. It is necessary to take off makeup at night. Cosmetics attached to the skin for a long time will do great harm to the skin and easily lead to skin aging.
2, usually pay attention to grasp the degree of makeup, do not wear heavy makeup, makeup will affect permeability, skin will feel dull and itchy.
3. Try to choose mild and non-irritating cosmetics, and you won't be able to buy inferior cosmetics for a while.
Extended data
1. Cosmetics related to hair dyeing, perming, whitening and freckle removal, manicure, lip beauty and breast augmentation often contain a lot of chemicals, which are likely to cause harm, and need detailed consultation to understand the situation.
2. Choose high-quality cosmetics: First, pay attention to check whether the cosmetics have trademarks, production dates, manufacturers' names and hygiene license numbers.
Don't believe in advertisements, especially those that say they have magical effects, which may contain some chemicals with miraculous effects but huge side effects.
4. Anti-allergy: Before choosing a new, unfamiliar or never-used cosmetic, you should do a skin test, such as a small area on the back of your hand, to test whether you are allergic. Only when there is no redness, itching and other reactions can you choose.
5. Pay attention to the shelf life: Cosmetics contain substances such as fat and protein, which are easy to deteriorate or be infected by bacteria after a long time.
6, pay attention to the details of use: different brands, different series, different types of cosmetics, do not mix, so as not to produce adverse reactions or bad smell.
