Cryptococcal dermatitis hyperpigmentation is considered to be post-inflammatory hyperpigmentation, and its self-healing time is usually about 3 months, but the time for the disappearance of its symptoms will be different due to the size of the lesions and the post-disease care. Post-inflammatory hyperpigmentation is a hyperpigmentation disease that occurs after a chronic or acute inflammatory process in the skin, which can subside on its own, and its self-healing time usually takes about 3 months. If the area of inflammation is large, the recovery time will be longer in comparison. In addition, the recovery time may be increased if the affected area is exposed to sunlight frequently due to improper post-inflammatory care. Therefore, it is impossible to generalize how long it will take to recover from post-inflammatory hyperpigmentation. For patients with post-inflammatory hyperpigmentation, the symptoms may subside on their own, and they need to protect themselves from the sun on a daily basis. If the symptoms can not subside, it is recommended that the patient go to a regular hospital, cooperate with the doctor for standardized treatment, such as follow the doctor’s instructions for external use of azelaic acid, hydroquinone and other drugs to help reduce and eliminate hyperpigmentation.
