Under normal circumstances, observation can be suspended, that is, if erythema, papules, itching, exudation, telangiectasia and pigmentation appear on the skin a few days after stopping using cosmetics (usually 3~ 15 days), it is the clinical manifestation of hormone-dependent dermatitis.

At this time, it is recommended to go to the hospital in time. Once hormone-dependent dermatitis is diagnosed, all suspicious cosmetics should be stopped, and clinically proved safe cosmetics recommended by doctors should be selected to cooperate with drug treatment. According to the hygienic standard of cosmetics issued by the Ministry of Health, it is forbidden to add hormones to cosmetics, even if it is a small amount.

Adding hormones to cosmetics has two main purposes. First, for ordinary people with healthy skin, after using cosmetics containing hormones, they will feel more energetic and whiter in a short time, resulting in the illusion that "the skin gets better instantly". The other is for the problem skin. Cosmetics containing hormones can control inflammation, so many people with acne or skin allergies feel good after using them.

However, as long as you start to use cosmetics containing hormones, you will become dependent on hormones over time, and some people's skin will become thinner and bloodshot will become more and more obvious. Some people also have symptoms of excessive hair and papules. After stopping using it, I felt my skin getting worse and worse or my face became red, itchy and rash.

Mask beware of fluorescent brighteners. Because the skin has a barrier function, many masks that claim to have a "moisturizing" function are actually difficult to let moisture enter the depths of the skin; In addition, many masks have added fluorescent whitening agents, which are carcinogenic. Chen Weihua suggested that as long as you apply moisturizing cream to your face, you can ensure that the moisture on your face will not evaporate. Generally, the moisturizing cream produced by regular channels on the market will not have a negative impact on the skin.

In the process of making cosmetics such as powder cake, lipstick and eye shadow, some lead components will be added to achieve uniform powder quality and lasting color. When you choose these make-ups, you can apply them on the back of your hand, gently stroke them with a pure gold ring, and then observe the traces. The darker the color of this sign, the higher the lead content.
