Pimple marks are small bumps that can be red, swollen, or have pus, the pinky-gray of the skin. These things are generated when the pores become clogged with oil and dead skin cells. Pimple marks are dark or red spots left behind after a pimple goes away. In order to reduce your chances of getting pimples, you should wash your face regularly, stay away from oily products, and never pick or squeeze the pimples. Apply products that contain benzoyl peroxide or salicylic acid to treat them.

It seems like your skin is dry and lacks brightness; besides the pimple scars on your nose. Skin becomes dull due to lack of water in it. Spots get darker as a result of spots. Drink water and wash your face regularly using mild soap then apply lotion too. In addition, you can wear sunscreen to prevent the darkening of these patches further.

It is possible that you are suffering from a skin condition called eczema. Eczema is a chronic condition that causes the skin to become irritated, red, and itchy. If the itching is severe or does not improve with over-the-counter treatments, you should see a dermatologist for further evaluation and treatment. A dermatologist can help diagnose the problem and provide you with the best treatment plan. They may suggest topical steroids, oral medications, light therapy, or other treatments to help control your symptoms.

You likely have a fungus on your testicle. The symptoms you have mentioned like the peeling of skin, white substance, and smell, along with itching, appear to be a normal fungal infection. They may be caused by the lack of hygiene or tight clothes. This can be solved by keeping a dry and clean environment, wearing loose clothes, and using a pharmacist-recommended antifungal cream.
