What are the medicines for treating skin problems?

In fact, there is no "universal conditioning drug" that can cure all skin problems. All drugs used for skin conditioning have to respond to the specific causes of skin problems, and most of them need to be used under the guidance of professional dermatologists. It is not recommended to follow the trend and buy them on your own.

Take the most common acne problem as an example. For ordinary red, swollen and inflammatory acne, you can usually just use some benzoyl peroxide gel. A while ago, my best friend stayed up all night for a week working on a project, and she developed several red pimples on her forehead that hurt when touched. She applied aloe vera gel on her own for three days, but it didn't go away at all. I went to the dermatology department of a community hospital and prescribed benzoyl peroxide. I applied it on the pimples after washing my face every day. In three days, the pimples shrank, and even the red marks were mostly faded. If you have closed acne that feels hard to the touch, Adapalene gel will be more effective. However, this product is a type of retinoic acid, so you need to slowly build up tolerance. Many people apply it all over their face and their skin explodes. People say that this drug is very irritating. In fact, as long as you only apply it for 10 minutes at a time and then wash it off, and gradually extend the stay time, there will be basically no strong discomfort.

If you have sensitive skin that is repeatedly red and itchy, doctors usually prescribe pimecrolimus or tacrolimus ointment in the acute stage of inflammation. There has always been a saying that these two drugs "can cause dependence." In fact, this controversy mainly comes from the usage: if you only use it for a short period of 1-2 weeks to control the inflammation and then gradually reduce the dosage and stop it, there will basically be no dependence rebound problem. If you use it as a daily skin care product for a long time, it is possible that the redness will worsen when you stop taking the drug.

There are also people with post-inflammatory hyperpigmentation and chloasma on the face. Many people say that the 2% concentration of hydroquinone cream makes them darken after use. In fact, most of them are not doing a good job in sun protection. Hydroquinone itself is photosensitive. If you apply it during the day and go out without sun protection, it will aggravate the pigmentation. If you follow the doctor's advice and use it at night and use sun protection, it is still the first-line medicine for lightening spots, and its effect is much more reliable than the whitening essence of most daily cosmetic lines.

Recently, the use of metronidazole gel to remove blackheads has been very popular on the Internet. This statement has not been recognized by the dermatology circle. Metronidazole is mainly anti-anaerobic. Blackheads are formed by the oxidation of oil secreted by sebaceous glands that clog pores. It is completely inappropriate. A while ago, a colleague of mine followed an online celebrity tutorial and applied metronidazole on his nose every day to remove blackheads. As a result, after two weeks of application, the blackheads were not reduced, and the skin around the nose was dry and red and itchy. It took more than a month to recover. Not to mention the isotretinoin that many people take orally. This is a prescription drug for severe cystic acne. You must take it strictly according to the dosage prescribed by the doctor. You must also check your liver function regularly and use contraception. Many people buy it overseas after seeing that others have taken it to treat acne effectively. In the end, they end up with cracked lips and aunts. There are many mothers with disorders. My cousin used to have cystic acne on his face. He went to a tertiary dermatology department several times. The doctor prescribed a dose for him to take on a regular basis. After half a year, his face was basically smooth and there were no serious side effects. In the end, you still have to follow the doctor's instructions and you can't make up your own.

In fact, choosing medicine to condition your skin is like choosing fertilizer for a potted plant. You must first find out whether it is deficient in fertilizer or infested with insects. Applying fertilizer indiscriminately will burn the roots. No matter how useful the medicine is, it is only a supplement. Regular work and rest, and basic cleansing, moisturizing, and sun protection are the most cost-effective "good recipes" for skin care.
