Many women pursue fashion and aesthetics when applying makeup, and often do not pay enough attention to the side effects of various cosmetics. In fact, cosmetics (including various shampoos, hair dyes, skin creams, facial cleansers, nail polishes, etc.) are chemical synthetic products. They not only protect and beautify the human body, but also volatilize various harmful substances. It has a great stimulating effect on human skin, and some can cause skin edema, itching, rash and other "cosmetic dermatitis".
The common cosmetics in life are mostly processed from various pigments, spices, preservatives, fungicides, etc. Some special-purpose cosmetics should also be added to hair care, hair dye, perm, beauty, bodybuilding, deodorization, and freckle. And sunscreen and other ingredients. Some people often use cheeks, redness, water, itching, dermatitis and other damaged face or cause skin allergies, especially long-term use of hair dye, not only easy to cause contact dermatitis, but also cause other diseases. In cosmetics, the side effects caused by the side effects of hair dyes are the most. According to the survey, a large number of hair dyes are susceptible to blood diseases and Hodgkin's disease.
Therefore, we should not underestimate the side effects of cosmetics, on the one hand, try to use as little as possible, and do not abuse it; on the other hand, if you choose carefully, you must use cosmetics with good quality, small side effects and suitable for your skin characteristics. Be especially careful when you have a history of skin allergies. If you find that cosmetics have an adverse reaction to your skin, you should stop using it immediately.
Another source of side effects is the use of improper use leading to deterioration. Usually, the most important ingredients of cosmetics are oil and water. The growth of microorganisms also requires water. Therefore, as long as it contains water, it will cause bacterial contamination and rancidity of makeup and skin care products. Other moisturizing ingredients such as glycerin and polyols can be used. Provides carbon sources for microorganisms such as bacteria, while main components such as proteins and amino acids provide the best source of nitrogen for microorganisms. During the use of cosmetics, the chances of direct contact between the product switch and the finger may be nearly one hundred or more, which is very easy to accelerate. Infection with microorganisms such as bacteria, if the so-called preservative or antibacterial agent is not properly added, it is likely to cause oxidation or contamination deterioration of the cosmetic.
