Scientists at the University of Wyoming discovered that most plants â even those on soils containing selenium â contained 10 parts per million or less of selenium, whereas a selenium level of 14,990 ppm was found in a sample of Astragalus racemosus, which is a selenium accumulator.
Popping Pimples Damages the Skin. Yes, popping pimples really is as bad for our skin as the experts (and Mom) says it is. An inflamed acne pimple happens when the pore becomes engorged with excess sebum, dead skin cells, bacteria and, often, pus. Next thing you know, you're standing in front of the mirror debating if the pimple is ready to pop.
Why does it occur. Acne occurs when glands (called sebaceous glands) in the follicles of the skin become overactive. These glands produce sebum, an oily substance that helps to stop the skin drying out.Someone with acne produces too much sebum, which forms a plug with dead skin cells and blocks the follicle.If the blocked follicle is close to the skin surface, it balloons outwards and forms a whitehead.everal factors can cause acne to get worse: 1  Changing levels of hormones in teenage girls and women, usually two to seven days before their period starts. 2  Oil from skin products, such as moisturisers and make-up, or grease in the workplace (such as a kitchen with fryers).
