Why is my neck and chest sweating with rash?

You might be suffering from a fungal skin infection known as ringworm. Ringworm can turn your skin into white, reddish, thick, dry, and scaly. Apart from that, the skin can get very itchy. Ringworm is a type of fungus that spreads through skin-to-skin contact. To help get rid of ringworm, you can use antifungal cream. However, it would be best if you cleaned and dried the area.

For healthy skin, cleanse daily and avoid harsh irritants. Stay hydrated by drinking plenty of water, as dehydration can make your skin look dull. Eat fruits and vegetables to get the nutrients your skin needs. Protect your skin from the sun by applying sunscreen every day. Clear, radiant skin comes from gentle cleansing, proper hydration, a nourishing diet, and sun protection.

I see that you are having dark spots on your face after getting a sunburn. This is called hyperpigmentation. It happens when your skin makes more pigment, called melanin, to protect itself from the sun. To help, avoid direct sunlight, use sunscreen, wear a hat, and apply aloe vera to soothe the burn. Over time, the dark spots may fade, but protecting your skin from the sun is key.
