Chest emblems, or markings, can come about naturally and can be associated with various causes, such as allergic reactions, skin infections, or dermatitis. Typical symptoms include redness, itching, and the appearance of a rash. It would be helpful to keep the area clean and well-moisturized and avoid irritants. Over-the-counter creams can help alleviate the discomfort. Nevertheless, one should be very careful to watch after the symptoms. If these signs do not go away, get worse, or are accompanied by more worried signs, it is better to consult a dermatologist for proper advice.
