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 ingredients, stay away from that product. If you have already purchased a product containing these types of ingredients, throw it out.

Acne Formation

Our skin's sebum is complex, composed of 6 or 7 main ingredients, including triglycerides and squalene, a precursor of cholesterol. The triglycerides are degraded on the surface of the skin by microbes to liberate fatty acids, which cause acne episodes in genetically predisposed families. As we will 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 ingredients, we should consider the purpose of sebum. We could be under the impression that sebum is vital to our skin's health. However, there is no evidence to back up that statement. Apparently, the discharge of sebum is simply a vestige whose usefulness has been lost in the path of evolution.

Sebum does not avoid wrinkles either. Wrinkling, or aging of the skin, is a reflection of accumulated sun exposure, and no moisturizer on the market is capable of reversing this exhaustion of tissues.

Harmful Ingredients in Acne Treatments

Three main categories of offending ingredients

Lanolins Lanolin is, perhaps, the most common ingredient in cosmetics. Lanolin is simply sheep skin oil taken from wool. The fatty acids in lanolin, just like fatty acids in our own oil, tend to aggravate some acne in the skin of individuals with inherited tendency towards acne. Many lanolin by-products commonly being used in cosmetics are harmful to acne-prone people, i.e., etoxylated lanolins and acetylated lanolins. The partially chemical lanolins are capable of permeating skin pores even better than biological lanolin. Lanolin oil, itself, is acceptable.

Isopropyl Myristate and its Chemical Cousins

One of the worst components is a penetrating oil called isopropyl myristate. It is the main ingredient in penetrating rust remover called Liquid Wrench. Isopropyl Myristate aids cosmetics go on more softly and have a slicker feel. This particular penetrating oil is so aggressive that if left over night in a beaker, it will actually move over the top, down the borders and onto the table top. There are several chemicals analogous to isopropyl myristate in cosmetics. The most common are: myristyl myristate, isostearyl neopentonate, putty sterate, isopropyl isothermal, isopropyl palmitate, octyl sterate, octyl palmitate, decyl oleate 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 troublesome recent findings about acne-producing potential is the red tints used in blushes. Some of the red dyes used in drugs and cosmetics are comedogenic. This discovery is not surprising considering they are coal tar by-products. Ever since doctors noticed that acne was an occupational hazard of chimney sweeps, coal tar has been known for its acne-causing properties. An adequate substitute for red color is carmine, a dye derived from insect wings and discovered by the Aztecs.

Always be on the look out for these comedogenic components. Take a moment and read product labels. This simple action can keep your skin beautiful and healthy.
