We are using a variety of cosmetics every day, and no matter which kind of cosmetics, are constituted by many harsh chemicals, some of the components have direct irritation to the skin, which will possibly result in skin sensitivity, pigmentation, acne and ever worse, cancer. So we must have a clear awareness and choose the products manufactured by qualified companies. Sometimes, inspection services by authoritative third party service provider are necessary.
1. Ethanol
Ethanol has two fatal weaknesses and because of which, large-scale and long-term use of some cosmetics is unfavorable. One defect is its high volatility. And in the process of volatility, moisture will be taken away from our skin. Another defect is the strong decomposition. When the facial oil is decomposed, the protection film on skin surface will be damaged; as a result, our skin will become sensitive and fragile. So using skin care products which contain ethanol in the dry season require our attention.
2. Salicylic acid (BHN)
Initial use of products containing salicylic acid, skin is felt like a boiled egg, soft and slippery. In fact, the reason is very simple, salicylic acid plays a role in cleaning aging skin. However, keratinocytes updated every 28 days, excessive elimination of stratum corneum will undermine the protective layer of skin, and cause erythema, itching, tingling or hypersensitivity. So the use of salicylic acid need to be careful, it is best to avoid direct contact with eyes, face and mucous membranes.
3. Tartaric acid (AHA)
AHA acid, by making your skin thinning, increases the whitening and exfoliating effect. Although the effect is obvious and immediate, you will soon find your skin become sensitive, even worse, when taking a serious look at cheeks, capillaries can also be seen under the skin. And AHA has a strong photonasty and your skin will be suntanned if using the skin care product in the morning.
4. Lead and its compounds
Lead and its compounds are often added into hair dye. In accordance with state regulations, the content of lead in hair dye products must be less than 0.6% (Pb meter), otherwise it will have side effects and release toxins. By absorbing through the skin, lead and its compounds may be hazardous to human health, particularly affecting the hematopoietic system, nervous system and kidneys.
5. Cadmium and its compounds
In cosmetics products, the content of cadmium and its compounds must not exceed 40mg/kg. The toxicity of cadmium is small, but cadmium compounds are highly toxic, especially the cadmium oxide. Damages from cadmium and its compounds are primarily to heart, liver, kidney, skeletal muscle and bone tissue.
