I am facing acne problem on my face. Mostly it is on my jaw line and chin area and on my cheeks as well. I am also facing hair growth a lot on my jawline area. What should be done for this?

I am constantly getting zits with white seeds near chin and cheeks.Please suggest something that can cure this permanently as I tried few medicines that only cure this for sometime.Once medical intake is stopped it starts popping up again.

What are the tests that can be done to determine deficiency of Vitamin B7.. Would appreciate a prompt response.

I have small black marks due to acne at my back ..which soap and moisturizer will reduce it .It's not fading away

I was prescribed Benzoyl Peroxide Face wash for Acne. It kept my skin clear for 3-4 weeks, but after that product became completely ineffective. I keep it in the bathroom. I read online that Benzoyl Peroxide goes bad if left in heat and moisture. Where should I keep it or store it?

Not sure about exact reason but the discoloration of skin in certain areas such as elbows, underarms, thighs etc is not going away. Can this be treated instantly? It's very much uncomfortable and am willing to resolve it if can be done in less time.

I have a cist on my back. There is etching and it has grown to a pretty big cist. I can't lie down flat.

For past 2-3 years, I have started seeing a burst of acne on my cheeks. There is always a pimple or two on my cheek. It is more on the left cheek than on right one. It is also leaving marks. I tried a few home remedies but did not get any results. Want to seek help in reducing acne and removing acne scars. I do not have any digestion problem and my periods are regular.

My skin tone is like an average indian complexion, not very fair not very dark. But lately, I'm seeing that my skin is becoming dark brown and pale. Due to lockdown I'm also not going out, I'm staying at home.. so what could be the reason why my skin is becoming black?
