Most of the scars left by cryptozoological dermatitis are post-inflammatory hyperpigmentation (referred to as “color deposition”), which can be eliminated through medication and laser treatment. 1. Medication: In the colored areas, hydroquinone cream and other decolorizing agents can be used externally to lighten the color deposits; oral tranexamic acid and other drugs can also be taken to whiten the treatment. 2. Laser treatment: Destroy melanin particles in the skin through the photothermal principle of laser, and then metabolize them through lymphatic reflux. Commonly used lasers include Q-switched laser, non-exfoliative fractional laser and so on. Besides, chemical peeling treatment, intense pulsed light treatment and radiofrequency treatment can also be used to lighten or eliminate the discoloration left behind by cryptorchid dermatitis. Scar marks left behind by cryptobiotic dermatitis can be eliminated by the above ways, but none of them can be solved at one time, so it is recommended that patients go to the hospital and choose the appropriate treatment according to the severity of the scar marks under the guidance of the doctor.
