First of all, crystal drops may release some harmful gases during heating. When the crystal drop is heated to a high temperature, the polymer material in it may decompose and release some harmful gases, such as formaldehyde and benzene. These harmful gases are harmful to human health, and long-term exposure to these gases may cause respiratory diseases and allergic reactions.
Secondly, some ingredients in the crystal drops may be irritating to the skin. If you contact crystal drops for a long time, or smear them on your skin, it may cause skin allergies, itching, redness and other uncomfortable symptoms. Therefore, when using crystal drops, you should try to avoid direct contact with the skin. In case of accidental contact with skin, immediately rinse with clean water and consult a doctor.
In addition, crystal drops may also cause irritation to eyes. If you accidentally drop crystal glue into your eyes, it may cause discomfort such as eye pain, redness and tears. If this happens, immediately flush your eyes with plenty of water and seek medical attention as soon as possible.
To sum up, crystal drops are non-toxic under normal use, but may produce some harmful substances under certain circumstances. Therefore, when using crystal drops, care should be taken to avoid prolonged contact, heating or accidental contact with skin and eyes to avoid discomfort. If you feel unwell, you should seek medical advice promptly.
