Skin, Hair and Nail Problems

I developed acne about two years ago, with widespread inflamed breakouts, and tried several treatments. I started using 10% azelaic acid, which worked well for around a year, but eventually stopped controlling my acne. The acne returned, along with tiny comedonal bumps, especially on my cheeks, and I also feel small acne-like bumps developing under my skin. A dermatologist then prescribed Requil 0.1% retinol, which I have been using for one month now(2 times a week). My skin texture has improved slightly, but I’m still experiencing breakouts and feeling under skin acnes, so I’m unsure whether it is working or if I’m purging. After researching, I’m considering 0.1% adapalene since its a more acne centred treatment but am unsure whether to switch or trust and continue retinol longer. I have spent thousands on my skin and I feel very stressed and frustrated from the unimproved condition. Attached images show before and after retinol condition.

I have intense dark circles around my eyes and not sure what to do to get ride of it. I sleep well and I don't even have any other issues which will cause this problem, I look tired because of this darkness around my eyesight

A small pin point like mole appeared on my face overnight. I have not noticed it before. I am bit confused its a mole or sun spot. Attaching image for reference.

The colour of skin between legs is so dark compared to other parts of my body. Similar issue for underarms. Can this be fixed

We have noticed some very small blister like spots on the forehead and upper skin of eyelid. Don't know how it came. What can it be? And how can it be cured?

Actually, my acne problem started suddenly about a week ago. I have developed a lot of acne on my face, and I want to get rid of it. Could you please tell me approximately how much the medicines would cost per month, how many months it might take for my acne to improve, and whether the treatment could have any side effects?

I sweat excessively, especially on my face. When I go outside in hot weather, I sweat a lot. I also sweat while cooking, and even after applying makeup, I start sweating just by walking for a short while. Most of the sweating is from my face. I have also noticed that the skin around my upper and lower lip has become tanned/darker, possibly due to frequent sweating. I would like to know why I am sweating so much and what treatment or skincare would help control the sweating and the pigmentation around my lips.

Im a student. I have tiny pimple (sometimes) , pimple marks, overall rough texture n pigmentation on my underside of butt cheeks. What exfoliating creams or options should I use to get them rid of? And get a smooth finish

I have 3–4 very small bumps on the skin of my penis near the base. I first noticed them around February, and they have stayed almost the same in size and number for about 6 months. They don't hurt, bleed, or cause any other symptoms. I showed them to a dermatologist earlier. He said they could be skin tags, especially since I had gained quite a bit of weight, but he was not completely sure and told me to observe them for a few months. I have also done STI tests for HIV, VDRL (syphilis), HSV-1, HSV-2, HBsAg (hepatitis B), and HCV (hepatitis C), and all were non-reactive. I'm attaching pictures from around 6 months ago and pictures from now. Could you please tell me what these bumps look more like — skin tags, another harmless skin condition, or genital warts? Does the fact that they have remained almost unchanged for 6 months make warts less likely? What would you recommend I do about them? I mainly want to know what they are and whether there is anything I need to worry about
