Most likely, you are faced with an ingredient called benzalkonium chloride, which can cause irritation to the skin. It is often found in hand sanitizers, so your fight against germs can cause itching and redness on the skin. This substance is also found in many eye drops as a preservative. Their use causes similar symptoms in the eye. An optometrist cannot predict how your body will react to this ingredient, but it can prescribe different eye drops for you to determine if you are allergic. The problem is that they may contain the same preservative that will only prolong the symptoms. Ask the pharmacist to pick up the drops without BH content. In the case of an antiseptic for hands, check the composition for the presence of this substance (some manufacturers indicate on the packaging that the product does not contain benzalkonium chloride).
It is well known that costume jewelry can cause an allergic reaction, since these products are often made from materials such as nickel. Your fitness tracker can also be made from metals that irritate your skin. Allergies to new devices may soon become commonplace. In fact, nickel is one of the most common allergens that cause skin rashes. These rashes can be observed several hours or days after using the product, so the culprit is quite difficult to detect. An allergist can do a patch test to determine the source of skin problems.
You enjoy a big juicy burger, as suddenly you get a rash. The bite of a dangerous tick can cause this strange allergic reaction. After being bitten by a paralyzing tick, you become more sensitive to the protein found in red meat. This is a very rare type of allergy, so if you have a rash for several days and you cannot determine the cause, you should seek professional help.
The use of sunscreen is necessary to prevent premature aging of the skin and the development of cancer. However, you can detect a negative reaction from the skin. If there is a burning sensation, tightness, or even a rash, you may be allergic to your favorite means of protection from the sun. Most often, an allergy occurs to products with chemical protection factors. But this does not mean that we must completely refuse from the SPF. 90% of melanomas (malignant tumors) are formed due to exposure to UV radiation. In this case, it is better to switch to mineral-based products that contain zinc oxide or titanium dioxide.
If you think that in the winter you do not have to sneeze and itch, then you are mistaken. In fact, when you spend a lot of time indoors, your body can react to most winter allergens, such as dust mites that live in decorative pillows on your sofa or bed. Their metabolic products cause an allergic reaction. Besides, you probably rarely wash such pillows. But simple washing is very effective in the fight against ticks. If you find yourself allergic to dust mites, keep such interior objects in minimal quantities.
