Do you really apply ointment?

According to incomplete statistics, there are about 0.42 billion people suffering from skin diseases in the world. Among them, there are about 0.15 billion patients with skin diseases in my country, and the number of patients is still growing. At present, we often relieve or cure some skin diseases by smearing external drugs. The process of this treatment is often operated by ourselves. If we do not master the use of external drugs, we will not only improve the condition, but even aggravate the skin diseases.
First, list a few common medication errors in life:
1. The thicker the ointment, the more effective it will be.
Some patients think that the more topical drugs are applied, the better the effect, and often a tube of ointment is applied in three to five days. However, this method is the most wasteful drug and the most harmful. Some experiments have proved that too much smearing at one time can not increase the absorption of drugs in the affected area and improve the drug effect, but it may increase the penetration of drugs into the blood circulation, resulting in systemic adverse reactions and waste at the same time.
2. Excessive cleaning
Some patients often pay more attention to the affected part of the skin, and will take pains to wash the affected part with water before and after each medication interval. This is also undesirable.
3. Cautious type
This type of patients are more common in female patients or parents of young children, worried about the various ingredients of external medicine, do they contain antibiotics? Do they contain hormones? Worried about too much medicine, they are all stained with cotton swabs of ointment, seemingly hygienic way, but because the ointment is absorbed by cotton, the amount of medicine and the strength of the application are insufficient, less transdermal absorption affects the therapeutic effect.
so how to properly apply ointment?
First of all, according to the fingertip unit application method (FTU) to select the appropriate amount of ointment. One fingertip unit is the amount of topical medication from the fingertip of an adult's index finger to the nearest interphalangeal joint. The fingertip unit application is a simple, personalized measurement that shows the amount of cream or ointment to be used for a skin lesion.
