Excessive Sebum production
Excessive production of SEBUM by the large sebaceous glands on the facial skin leads to oily skin. This excessive sebum production is thought to be due to over sensitive receptors in the hair follicle to the hormone Dihydroxy testosterone that controls sebum production.
Excretion of excessive Sebum is a major causative factor in acne. People who have acne usually produce more sebum than those who have no acne. Some people believe that this OILYNESS on the skin is a result of eating oily food.Diet has no effect on sebum production.This is under the control of the hormone Testosterone.(often made worse by hot,humid conditions)The Sebaceous glands which produce Sebum are attached to the hair follicle,of which there are millions in the skin.The follicles are tubelike structures through which the Sebum flows from within the skin on to the surface of your skin.The follicle acts as a pipeline to the surface of the skin and can be observed as a pore on the skin.The oil flows to the skin surface in this tube.
Acne and Spots are caused by "clogged up pores"(MICROCOMEDONES).
The pores being the sebaceous duct and hair follicle. Clogged up pores full of sebum, dead skin cells and bacteria are an ideal combination for an inflammatory reaction that leads to spots. Blackheads (open comedones) and whiteheads (closed comedones) are formed due to inflammatory action of fatty acids-chemicals that are made by the action of bacteria on the sebum and dead skin cell plugs in the clogged up pores. These fatty acids cause inflammation and enlargement of the pore, leading to what we call a pimple-a nasty looking, reddish, inflamed "zit" or pimple.
The plugged pore(or a MICROCOMEDONE)
The plugged pore is occlusive and leads down to the hair follicle. Lack of oxygen causes accumulation of stagnant sebum which encourages the proliferation of anaerobic bacteria, especially the species Propioni Bacterium Acnes, Staphylococcus Albus and Corynebacterium Acnes. Despite the blockage, glands in the skin carry on producing sebum oil, resulting in a swelling behind the blockage which causes a white head spot, or a blackhead if the sebum is mixed with the skin pigment melanin and exposed to air but still stuck in the pore.
work to prevent MICROCOMEDONES and keep pores open and unblocked
is antibacterial and keratolytic.
work by reducing inflammation and reducing the bacterial population (propionibacterium acnes) on the skin.

Acne is best treated and prevented by addressing ALL the factors that lead to the formation of lesions. Therefore it is logical to combine treatment with products that address different causative factors(sebum, bacteria, dead skin). The action of each preparation will be ADDITIVE and lead to a more effective and faster result than can be achieved by a single product alone. It is usual to apply one product in the morning and a different one in the evening. However there are also products available that contain TWO of the active agents in the one application. All sufferers want instant results. You can help yourself by using this technique.
