Circumcision is surgery to remove the skin at the very tip of the penis.
Baby boys are born with a loose flap of skin that covers and protects the rounded top part of the penis. This skin is called the foreskin. It contains nerves, blood vessels, and a tiny part of muscle.
When you are born, the foreskin is stuck to the penis. It separates as you grow up. This allows urine to better exit the body and lets the skin pull back when you have an erection.
Here are answers to some of the most commonly asked skin care questions.
I have pimples. What should I do?
Pimples begin when the pores in your skin get clogged with a type of oil called sebum.
Some sebum is important to keep your hair and skin from drying out. But hormone changes can cause your body to make too much of it.
Here are steps to get rid of pimples -- and keep new ones from forming:
Wash your face twice a day with a gel-based or foaming cleanser.
Avoid harsh soaps and products containing alcohol.
When washing your face, gently massage it with circular motions.
When you have finished washing, use a lotion with the acne medicine benzoyl peroxide. You can get these in the drug store or supermarket without a prescription.
If zits are interfering with your life or if they don't improve with your daily cleansing routine, you may want to see a dermatologist (a doctor who specializes in skin conditions) to prescribe a stronger medicine. There are also many things you can do on your own to help.
Don't pop pimples. Popping pimples can make them look worse and may cause them to leave a scar.
Keep your hair off your face, neck, or other pimple-prone areas. Oil and dirt from your hair can block pores. If you want to wear your hair longer, make sure you keep it clean.
Don't touch your face. This can spread bacteria that irritate pores.
If you wear glasses, keep them clean. Cleaning them can help keep the oil on them from blocking the pores where they touch your face.
If you follow these steps, you'll also help keep your face from getting greasy. Greasy skin can lead to pimples.
I have acne scars. Will they go away?
First off, to reduce scarring, never squeeze zits. If a pimple does leave a red or brownish mark it should eventually go away on its own. Be patient -- it could take a year or more.
If your acne is under control but past pimples have left scars, there are things your dermatologist can do to help get rid of them.
The best treatment will depend on the type of scar and how bad it is. But these treatments aren't usually recommended for teens. Your dermatologist can give you more information.
