Sebum is the substance that moisturises the skin. It is manufactured deep inside the pore and it cannot get out if the top of the pore is clogged by these dead skin cells. When it gets trapped beneath the skin, conditions for the germs to settle in are optimal. This will lead to the bacteria breeding and multiplying and causing inflammation to the skin. These bacteria are normally present on the skin without causing much harm. When they increase in numbers then the immune system of the body will be forced to act. This results in the pimples and spots as the white blood cells of the body come to the rescue of the inflamed part.
A red appearance on the skin is an indication of this inflammation. The spots can enlarge as the white blood cells coming in increases. Pustules containing pus may develop and these will progress into nodules and cysts. Scaring can result from these conditions. Darker skinned people may suffer from the scars still being visible after the initial problem has cleared up.
9 out of 20 teenagers get acne. 3 out 0f 10 need further treatment. This is necessary in order to prevent scarring. Boys are more prone to getting it then girls. Several months of treatments may be required to help clear and keep the acne away. Maintenance treatment which means the occasional use of a topical treatment may still be required to keep future outbreaks under control.
This problem is caused by plugged or blocked pores. The dead skin cells which are shed will make the top of the pores get thicker. Tiny spots called blackheads and whiteheads will then appear. Skin pigment gives the black heads its colour. Most people may however think that it is the collection of dirt which is not the case.
Toothpaste is a readily available and could help in drying out the pustules. Applying it at night on top of the pimple before going to bed will help. It can also help in curing the spots. Already existing blemishes will be reduced as well.
Stress can make acne worse. Many different situations in life can cause stress. For the teenagers exam time is the most common trigger. Cells that produce sebum have receptors for stress hormones. Stress will serve to up-regulate the sebum producing hormones. More oil will be produced than normal and will clog the hair follicle and lead to the formation of a greater amount of acne. Acne levels are known to reduce greatly during the summer time, when the teenagers are mostly relaxed.
