Tattoos: Understand risks and precautions


Tattoos may be more common than ever, but don't take tattooing lightly. Know the risks and understand basic safety precautions and aftercare steps.

You could be the proud owner of a new tattoo in a matter of hours — but don't let the ease of getting tattoos stop you from making a thoughtful decision about permanent body art. If you first take steps to protect yourself from possible risks, what seems like a cool idea now is less likely to turn into a source of regret later.


How tattoos are done


A tattoo is a permanent mark or design made on your skin with pigments inserted through pricks into the skin's top layer. Typically, the tattoo artist uses a hand-held machine that acts much like a sewing machine, with one or more needles piercing the skin repeatedly. With every puncture, the needles insert tiny ink droplets. The process — which is done without anesthetics and may last up to several hours for a large tattoo — causes a small amount of bleeding and slight to potentially significant pain.


Know the risks


Tattoos breach the skin, which means that skin infections and other complications are possible. Specific risks include:


Allergic reactions. Tattoo dyes — especially red dye — can cause allergic skin reactions, resulting in an itchy rash at the tattoo site. This may occur even years after you get the tattoo.




Skin infections. Tattoos can lead to local bacterial infections, characterized by redness, swelling, pain and a pus-like drainage.


Other skin problems. Sometimes bumps called granulomas form around tattoo ink — especially red ink. Tattooing can also lead to raised areas caused by an overgrowth of scar tissue (keloids).




Bloodborne diseases. If the equipment used to create your tattoo is contaminated with infected blood, you can contract various bloodborne diseases, including hepatitis B, hepatitis C, tetanus and HIV — the virus that causes AIDS.


MRI complications. Rarely, tattoos or permanent makeup may cause swelling or burning in the affected areas during magnetic resonance imaging (MRI) exams. In some cases — such as when a person with permanent eyeliner has an MRI of the eye — tattoo pigments may interfere with the quality of the image.


Medication or other treatment may be needed if you develop an allergic reaction, infection or other skin problem. In some cases, the tattoo may need to be removed. Keep in mind that tattoo inks are classified as cosmetics, so they aren't regulated or approved by the Food and Drug Administration (FDA).


Insist on safety precautions


To make sure your tattoo will be applied safely, answer these questions:


Who does the tattooing? Go to a reputable tattooing studio that employs only properly trained employees. Keep in mind that regulation requirements and licensing standards vary from state to state. Check with your city, county or state health department for information on local licensing and regulations.



Does the tattoo artist wear gloves? Make sure the tattoo artist washes his or her hands and wears a fresh pair of protective gloves for each procedure.



Does the tattoo artist use proper equipment? Make sure the tattoo artist removes a needle and tubes from sealed packages before your procedure begins. Any pigments, trays and containers should be unused as well.



Does the tattoo artist sterilize nondisposable equipment? Make sure the tattoo artist uses a heat sterilization machine (autoclave) to sterilize all nondisposable equipment after each customer. Instruments and supplies that can't be sterilized with an autoclave — including drawer handles, tables and sinks — should be disinfected with a commercial disinfectant or bleach solution after each use.




Also ask yourself whether you truly want to invest in permanent body art. Choose the location of the tattoo carefully. Don't get a tattoo if you're under the influence of alcohol or drugs or worry that you might regret the tattoo later.


Take good care of your tattoo


How you care for your new tattoo depends on the type and extent of work done. Typically, however, you'll need to:


Remove the bandage after 24 hours. Apply an antibiotic ointment to the tattooed skin while it's healing.


Keep the tattooed skin clean. Use plain soap and water and a gentle touch. Pat — don't rub — the area dry.


Use moisturizer. Apply a mild moisturizer to the tattooed skin several times a day.


Avoid sun exposure. Keep the tattooed area out of the sun for at least a few weeks.


Choose clothing carefully. Don't wear anything that would stick to the tattoo.


Allow up to 2 weeks for healing. Don't pick at any scabs, which increases the risk of infection and can damage the design and cause scarring.


If you think your tattoo may be infected or you're concerned that your tattoo isn't healing properly, contact your doctor. If you're interested in tattoo removal, ask your dermatologist about laser surgery or other options for tattoo removal.

这是每一个想创业的人必须回答的终极问题. 在你开始创业之前,请认真思考一下,自己是否真的具备创业的决心和迫切欲望. 因为在生活中,荣耀的代价向来不菲,而在这个特殊的竞技场上,对于大多数人而言,代价可能更为高昂. 毕竟,当你不惜一切代价投身事业之时,“一切代价”不只是说说而已——它很可能成为现实. 你不能简单地仅以自己的资金来衡量创业的风险.

我在《金融对赌不是无价值交易》里分析了衍生品的风险配置功能,如何使得包含复杂风险的生意得以展开,从而推高整个经济水平;从我得到的一些反馈看来,许多朋友没能理解这一分析,或许通过类比和例子能够看的更清楚. 说到生产分工,一般想到的是效率改进和相应的成本节省,即,每个生产者若专注于某一工序,不断重复,会更加熟练高效;这没错,不过生产分工有另一个常被忽视但或许更加重要的效果:它拓展了生产的可能性,即,使得许多原本不可能的生产成为可能.
