How do we know if a skin infection is due to fungus or bacteria? How much is the estimated cost to get treatment? Thank you.
Doctor, is face whitening cream safe for our skin? My skin is on the tanned side and I do not feel confident about it. I bought a whitening cream online. After one month of usage, my skin is hot and peeling. Is that normal? Should I continue to use the product?
Doctor, sometimes when I am at a dusty place, I find red specks appearing suddenly on my arm. They don't itch, nor do they hurt. I usually treat this with an ointment from the pharmacy. However, if I enter a dusty place again, the same condition recurs. Is this an allergy? Is it okay if these specks keep appearing?
Doctor, I am 18 years old. I tend to sweat a lot - until my shirt is soaked. I don’t do strenuous activity though. Is that normal? What should I do to reduce excessive sweating?
Doctor, my son is 20 years old and he has some warts on his face. What is the cause? Are there any foods he should avoid? What is the solution and how much is the estimated cost to treat this problem? Thank you
Doctor, can I ask if moles are dangerous? I read an article that said a mole can turn into a tumor or cancer. I have a mole on my chin and I feel like it has grown bigger these 2 years. Should I be worried and see a dermatologist?
Dotorc, my son is 23 years old. He has some bald spots on his head. Some say the bald spots are due to fungal issues. I took him to a doctor who said it was baldness and that my son has very slow hair growth. What is the cause, Doctor? What should I do?
Hello Doctor. This past month, I have been having chapped skin on my right palm. It feels hot and itchy. This problem started after I wash the dishes. Does it mean I am allergic to dish soap, even though I have never had an allergy to any kind of soap before? How do I treat this allergy on my palm?
Doctor, the skin on my face has all along been dry - it's now gotten drier as I spend a lot of time in an air-conditioned room. I am not comfortable with my skin as it's sometimes chapped near the nose and mouth. Are there any suggestions on how I can treat dry skin, Doc?
Hi Doctor. Are there any foods that can whiten the skin? My skin is brown. I have tried whitening creams but the result was awful, with my face turning hot and chapped. I would like to whiten my skin naturally. Can my skin turn white by consuming certain foods?
Doctor, I have been living with a red circle on my face since I was born. People say it's a birthmark but my parents do not have something similar. Can it be removed so that I can be more confident?
Doctor, why are there red spots on the head of my penis? Urinating does not hurt for me though, and there is no pus.
Good morning, I read that it is common now to use long term maintenance therapy by Isotretinoin in low doses. I got one full dose of isotretinoin course 5 years ago (male, aged 35 years) for adulthood bad acne. My acne relapsed two years later and I got a few months on Doxybene - relapsed, so then I got a few months of 20 mg of isotretinoin daily, then 10 mg daily and now it is maintainance 3x10 mg weekly for more than one and a half years. It seems that for me, an effective amount is 30 to 40 mg of isotretinoin weekly. I have no issues, no side effects and acne and face seborrhea is gone. Is it possible to continue in this maintenance isotretinoin regime for long term? For years? I found articles that it is possible and even some dermatologists themselves use this regime only for oily skin. In our country it is not common and my doctor want me to stop treatment by isotretinoin. It also keeps my face seborrea under control. Thank you for your response.
