How to control pimples? Tips to avoid pimples.
Acne is a common problem faced by most of the teenager and youth. ACNE is actually caused because of lack of hormone imbalance. Our skin will break out because of a hormone called testosterone. Both men and women will have testosterone in their system.

There are lot of home made remedies to get rid of pimples should wash our hands and faces after heavy work, and steam the face once in a week which may kills the dead cells in our skin, vinegar can help to clear up the skin.

If you're going to pop your pimples, learn how to pop up the pimple correctly. The reason you're not supposed to pop pimples is that anytime you can break your skin, you risk creating a scar or infection through the break in the skin. If a pimple appears in a particularly bothersome place.

avoid pimples


Wash your hands thoroughly, especially underneath the nails. You'll want to avoid letting your fingers and nails actually touch the pimple, but just in case they do, having them clean will reduce the likelihood of irritation and infection.

Should clean the skin surrounding the pimple with an antibacterial cleanser. When you pop the pimple, you'll be opening the skin, creating a way for bacteria to enter. The pimple will heal faster if you don't give bacteria a chance to settle in and create an infection. In the process, you'll also be removing any oil, sweat, dirt, and makeup.

Find the center of the pimple (the highest point) and plant the pads of your fingertips evenly on each side. Instead of pushing your fingers together, like most people do, you want to pull the skin apart, it should pull apart easily, allowing the pus to come out. Now massage the skin around the pimple to encourage the remaining pus to come out, but don't touch the pimple itself, except to blot away the pus. There should be no bleeding whatsoever. If there is, you've squeezed too much, and created a wound that may scar.

Wipe the area with an antiseptic solution. Again, the important thing is to make sure bacteria doesn't invade the opening in the skin.

Apply a benzoyl peroxide acne treatment right on the pimple (not around it). This will help oust any bacteria that was inside the pimple.

REGENERATION

REGENERATION 
 

      Regeneration is a Biological process in some living organisms including both plants and animals. Regeneration is an ability to recreate or replace the  lost  or damaged or amputated parts like limbs, organs  or tissues  thereby restoring the  original function of the particular lost / damaged part.   

      Regenerative capacity is inversely related to the complexity of the body structure i.e., more complex the structure of an animal less the  capacity of regeneration

Ex. Mammals cannot regeneration generate.  While organisms like sponges, planarians have an enhanced capacity to regeneration generate;.  

      The ability of regeneration varies  greatly among living things.  Plants can regenerate  all parts of its from precursor cells, as Trees  which is cut off to the ground level , in due course, sprouts starts appearing at the margins of the stump. Then grow on to develop new stems, leaves and flowers. 

      Coming to the Regeneration in animals, Invertebrates like Sponges, Hydra, Planarian are capable of regenerating   entire body from  just a conglomeration of their cells.  Starfish can regenerate the entire organism from just one arm and the central disk. 

      In  Vertebrates   ability of regeneration is found in Amphibians and Reptiles.  Amphibians  can regeneration a missing tail, legs and even eyes,  This remarkable ability is particularly pronounced in the larval stage.  

      Regeneration process is extended to human beings also to some level.  In 1970, studies showed that children up to the age of 10 who lose fingertips in accidents can regenerate the tip of the finger within a month provided their wounds are not sealed up with flaps of skin. There are some references claiming that human ribs could regenerate if the Peritoneum the membrane surrounding the ribs were left intact.  The  Human liver is one the few glands  in the body that has the ability to regenerate  as little as 25% of its tissue. Regenerative Capacity of the Kidney remains largely unexplored.  The regenerative capacity of the mammalian Kidney is limited compare to that of lower vertebrates. Like other organs, the Kidney is also known to regenerate completely in lower vertebrates such as fish. Some of the known fish that show remarkable capacity of kidney regeneration are goldfish, skates, rays and sharks.
