Acute eczema usually subsides in 2 to 4 weeks, and it is impossible to generalize the exact time due to the different conditions of patients. Acute eczema is a recurrent skin disease, which has the possibility of self-healing, but can recur. Patients with acute eczema experience symptoms such as intense itching and rashes. Usually, if the patient’s symptoms are mild, the clinical symptoms can gradually subside in about 2 weeks, and its recovery time is relatively short. However, some patients with acute eczema have more acute onset and severe clinical symptoms, the recovery time is relatively long, and it may take about 4 weeks to recover after standardized treatment. If patients are diagnosed with acute eczema, they should follow the doctor’s instructions and undergo regular checkups during the treatment period in order to understand the recovery of the disease.
