How are blemishes on my chin related to my hormones?
Mehmet Oz, MD, Cardiology, answeredPimples on your chin can be related to changing hormone levels within your body and to touching your skin. Persistent adult-onset acne -- which occurs when people are in their 20s, 30s, 40s, and 50s -- usually appears on the lower face, including the chin. Women are at higher risk for this type of acne because their hormone levels can fluctuate with their menstrual cycle, pregnancy, and menopause. In addition, putting your hands on your chin can irritate your skin, increase sebum (an oily substance produced by the skin's sebaceous glands), and add certain germs such as Propionibacterium acnes (P. acnes) to your skin. If the skin has too many dead skin cells and too much oil, the skin pores can get plugged. When bacteria increase and settle inside the plugged pores, it causes inflammation, redness, and raised bumps or pimples.

How does a doctor diagnose plaque psoriasis?
Michael Roizen, MD, Internal Medicine, answered
A doctor can diagnose plaque psoriasis simply by examining it closely either with his or her eyes, or with the help of a microscope. Plaque psoriasis is similar to other skin conditions, like atopic dermatitis (a form of eczema), so careful examination can be key to making an accurate diagnosis.
