synthetic

Welcome to my final installment on makeup brush hair types. Today's topic is synthetic hair. Sometimes faux is the way to go! Cosmetics companies make makeup brushes from a synthetic material like nylon as opposed to natural hair because this type of bristle is less expensive, and it provides a smooth and even finish for cream products. (Since it lacks a cuticle, it can't trap makeup.)

A common type of synthetic hair used to apply concealer, cream shadow, cream blush or cream foundation is taklon. This is a fine-grade nylon that is less absorbent than natural hair.

An excellent nylon brush is this Laura Mercier Creme Blush Brush ($36) which happens to be the perfect size to add natural definition to the cheeks. The downside of taklon is that it is less durable than natural hair brushes, and synthetic brushes also tend to become very stiff over time.

What you put on your body is just as important as what you put in it. Your skin is the largest organ in your body, and it absorbs everything including toxins. If you are concerned about not eating unhealthy foods like trans fat, then you'll definitely want to know which synthetic ingredients you should watch out for in the products you use.

1. Methyl, Propyl, Butyl and Ethyl Parabens: Used as a preservative to inhibit microbial growth and extend shelf life. Unfortunately, it can cause allergic reactions and skin rashes. Preliminary research found parabens in human breast cancer tumors.
2. Diethanolamine (DEA), Triethanolamine (TEA): These are used as foaming agents, but can cause allergic reactions, eye irritation, and dryness of the hair and skin. DEA and TEA are toxic if absorbed into the body over a long period of time, and are associated with cancer in lab animals.
3. Diazolidinyl Urea, Imidazolidinyl Urea: Often used as preservatives, the American Academy of Dermatology has found these chemicals to be a primary cause of contact dermatitis (irritation caused by foreign substance). Both these chemicals release formaldehyde, which can be toxic.
4. Sodium Lauryl/Laureth Sulfate: This is a cheap, harsh detergent used in many shampoos for its ability to cleanse and foam. Often derived from petroleum, it causes eye irritation, dry scalp, skin rashes and other allergic reactions. Be on the lookout for pseudo-natural products that list this ingredient with the phrase "comes from coconuts" - it's still bad for you.
5. Petrolatum: Also known as petroleum jelly, this is a mineral oil derivative that can clog your pores. This in turn disrupts your body's natural ability to moisturize its own skin, leading to dryness and chapping. Manufacturers use it because it's really inexpensive.

Many of today's vitamin and mineral supplements are made synthetically through chemical processes, rather than derived directly from plants or other foods. Some manufacturers do make supplements directly from natural sources, and claim that these vitamins are superior in quality to their synthetic cousins.

So which ones are better for you?

Basically, it comes down to science. If the molecular structure of a synthetic vitamin and one made from natural foods are the same, then there is no real difference between their effects on the body.

Most synthetically made vitamins are identical to the natural ones. If one says, "better quality," don't rely on that unless their claim is backed up with scientific evidence or reasoning.

The list of ingredients and their amounts are the most important aspects to look at when comparing the two. If the lists are the same, then go for the cheaper one. Some synthetic vitamins contain artificial chemical colors, or are made with products that some people are allergic to. If this is the case, you may want to choose the food based, natural vitamins.

Fit's Tips: Just so you know, most synthetic vitamins and nutrients are both cheaper and purer.
