When considering self-deployment of ointments to treat skin diseases, it must first be emphasized that the treatment of skin diseases should follow the guidance of professional doctors. There are serious risks of self-use of chemicals to deploy ointments, which may lead to skin irritation, allergic reactions, increased infection and even systemic side effects. Here are some important tips： ### 1. **Professional medical advice is preferred** -There are many types of skin diseases (such as eczema, psoriasis, fungal infections, etc.), and the cause needs to be determined through professional diagnosis. Self-medication may mask the condition or delay treatment. -The doctor may prescribe clinically proven topical ointments (such as preparations containing hormones, antibiotics, or antifungal ingredients), which must be used strictly as prescribed. ### 2. **Risk warnings for common ointment ingredients** -**Hormones (such as hydrocortisone)**: Abuse may cause skin thinning, pigmentation, or dependent dermatitis. -**Antibiotics (such as Mopiroxacin)**: Improper use may cause drug resistance. -**Antifungal agents (such as clotrimazole)**: Use after confirming the type of infection. -**Natural ingredients (such as aloe vera, tea tree oil)**: Some may be sensitized, and improper concentration can irritate the skin. ### 3. **Absolutely avoid dangerous behavior** -Do not mix chemicals (such as acids, alkalis, or unknown raw materials), which may cause chemical reactions and cause burns. - Avoid the use of industrial raw materials or non-medicinal grade chemicals (such as sulfur powder, high-concentration alcohol), which may contain impurities or irritating substances. ### 4. **Safety alternative recommendations** -**Moisturizing care**: Fragrance-free petroleum jelly or medical moisturizing cream can relieve some dry skin diseases. -**Gentle cleaning**: Use warm water and hypoallergenic cleaners to avoid scratching or rubbing. -**Medical channels**: If you cannot see a doctor in time, you can consult a dermatologist through a regular Internet hospital. ### 5. **Legal and health responsibilities** -In China, the preparation of drugs without permission may violate the "Drug Administration Law". -The skin is an important barrier to the human body, and improper treatment may cause irreversible damage. Please be sure to take safety as the primary principle and seek professional medical help in a timely manner. Health problems cannot be experimented with, and scientific treatment is the best choice.
