Comedogenic is an important word to know when dealing with acne and cosmetic products. Its definition is "tending to produce or aggravate acne". Therefore, a comedogenic ingredient or product is one that will only make your acne problems worse.

For this reason, it is a good idea to read the label of your skin care and cosmetic products before buying them. If you find any comedogenic components, stay away from that product. If you have already purchased a product containing these types of components, throw it out.

Acne Formation

Our skin's sebum is complex, composed of six or seven main components, including triglycerides and squalene, a precursor of cholesterol. The triglycerides are degraded on the surface of the skin by bacteria to free fatty acids, which cause acne breakouts in genetically predisposed families. As we shall see, many cosmetics also contain these acids. Unfortunately, some cosmetics contain esters of fatty acids such as isopropyl mystrate or butyl stearate which are more likely to boost the production of some acne lesions. These cosmetics can interfere with traditional adult acne treatments.

Before we discuss cosmetic components, we should consider the purpose of sebum. We could assume that sebum is vital to our skin's health. However, there is no evidence to that effect. Apparently, the discharge of sebum is just a vestige whose usefulness has been lost in the path of evolution.

Sebum doesn't avoid wrinkles either. Wrinkling, or aging of the skin, is a reflection of accumulated sun exposure, and no moisturizer in the world is capable of reversing this exhaustion of tissues.

Harmful Ingredients in Acne Treatments

Three main categories of offending components

Lanolins Among cosmetics ingredients, the most commonly used is lanolin. Lanolin is basically sheep skin oil extracted from wool. The fatty acids in lanolin, just like fatty acids in our own oil, can accentuate some acne in the skin of individuals with genetic tendency towards acne. Many lanolin derivatives currently being used in cosmetics are damaging to acne-prone people, i.e., etoxylated lanolins and acetylated lanolins. The partially synthetic lanolins are able to permeate skin pores even better than biological lanolin. Lanolin oil, itself, is acceptable.

Isopropyl Myristate and its Chemical Cousins

One of the strongest products is a penetrating oil known as isopropyl myristate. It is the main component in penetrating rust remover called Liquid Wrench. Isopropyl Myristate helps cosmetics go on more smoothly and have a slicker feel. This particular penetrating oil is so invading that if left over night in a beaker, it will actually migrate over the top, down the borders and onto the table top. There are many chemicals similar to isopropyl myristate in cosmetics. The most common are: decyl oleate, isopropyl isothermal, octyl sterate, isopropyl palmitate, putty sterate, myristyl myristate, octyl palmitate, isostearyl neopentonate and isocetyl stearate and PPG myristyl propionate. All must be avoided, as must other surfactants such as laureth-4.

Drugs As Acne Treatments

Maybe one the most disturbing recent findings about acne-causing potential is the red colorations used in blushes. Some of the red dyes used in drugs and cosmetics are comedogenic. This discovery is not unexpected considering they are coal tar derivatives. Ever since doctors realized that acne was an occupational hazard of chimney sweeps, coal tar has been known for its acne-causing properties. An adequate substitute for red tincture is carmine, a dye derived from insect wings and discovered by the Aztecs.

Always be on the look out for these comedogenic components. To keep your skin healthy, remember to read product labels. This simple tip can mean the difference between beautiful and damaged skin.
