Detailed answer

Witch hazel has natural astringent properties that can help soothe skin irritation and reduce inflammation. It can be beneficial in treating mild skin rashes, such as those caused by insect bites or contact dermatitis. To use witch hazel for a skin rash, apply it directly to the affected area using a cotton ball or clean cloth. Gently dab the witch hazel on the rash and let it air dry. Repeat this process 2-3 times a day until the rash improves. However, if the rash persists or worsens, it is recommended to consult a healthcare professional for further evaluation and treatment.
