The ingredients inside the 999 dermaplanin are actually mainly dexamethasone, also known as dexamethasone acetate, which is a glucocorticoid-like drug. For some inflammation of the skin, it has a certain elimination effect, and at the same time has a certain anti-itch effect. As the ointment contains certain menthol, camphor and other substances, so after applying to the skin, there is a certain cool feeling, but also has a certain role in killing itch, so 999 dermatoprene is very widely used in clinical practice. But because the cream after all contains glucocorticoids, so not for long-term use, if the patient reluctantly use these creams, regular use, may cause the area of the skin a certain skin atrophy, capillary dilation, or secondary skin infections and so on.
