Do You Really Need Eye Cream?


Eye Cream


You've heard the promises: Eye creams reduce or even erase the signs of aging: fine lines, wrinkles, and dark circles. But aren't eye creams just more-expensive moisturizers in a smaller package?

Not necessarily, says dermatologist Patricia Farris, MD, a clinical associate professor at Tulane University School of Medicine. "Eye creams are formulated specifically for the delicate skin around the eye, so they tend to be thicker. They contain more oil than a regular facial lotion, and they have a lot of active ingredients aimed at the problems we see around the eyes," Farris explains.
The skin around the eyes is more fragile, more prone to dryness, and quicker to show age and fatigue. Squinting and constant movement of the eyes also hasten the appearance of lines and wrinkles, and fluids collect under the eyes and cause puffiness and dark circles. Eye creams can address some of these issues.
Fine lines and wrinkles come from both sun damage and your skin making less collagen as you age. Collagen helps maintain skin's elasticity. Vitamin C, peptides, and retinol have boosted collagen production, studies of skin creams show. Ceramide and hyaluronic acid also help; these are moisturizers that help prevent water loss in the skin and improve elasticity.
"Retinol is one of my personal favorites," Farris says. But it can be harsh on some skin. RoC Retinol Correxion Sensitive Eye Cream ($22.99) contains a gentle dose of retinol along with hyaluronic acid.
Dark circles under the eyes come from genes, sun damage, age, and blood build-up. Sodium ascorbate, or vitamin C, can thicken the skin and help conceal dark circles after about 6 months. Niacinamide, or vitamin B3, and kojic acid can lighten dark circles.
Farris likes Olay Regenerist Eye Regenerating Cream Plus Touch of Concealer ($21.99), which contains vitamin B3 to lighten dark circles and peptides to boost collagen.
Puffiness is a buildup of fluid and blood under the eyes. Some studies show that caffeine can help circulation, which could reduce puffiness. Other studies show that cold temperatures are just as effective to treat puffiness. That's why some people refrigerate their eye creams.

Is there a medication to thicken eyelashes?


Yes. The medication bimatoprost — marketed under the brand name Latisse — is approved by the Food and Drug Administration (FDA) to treat inadequate eyelashes (hypotrichosis). 

Bimatoprost is also marketed under the brand name Lumigan, which is used in prescription eyedrops to treat glaucoma. Eyelash growth was an unexpected side effect of Lumigan, which led to the creation and marketing of Latisse.

With regular applications along the lash line of the upper eyelid, Latisse gradually encourages growth of longer, thicker and darker eyelashes. Latisse isn't meant to be applied to the lower eyelid. 

For full results, you must use the medication daily for at least two months. Eyelash improvements remain as long as you continue to use the medication. When you stop using Latisse, your eyelashes will eventually return to their original appearance.

Potential side effects of Latisse include:
Itchy, red eyes
Dry eyes
Darkened eyelids
Darkened brown pigmentation in the colored part of the eye (iris)
Hair growth around the eyes if the medication regularly runs or drips off the eyelids

Although darkened eyelids might fade when the medication is stopped, any changes in iris color are likely to be permanent.

In one small study of people who have eyelash loss due to alopecia areata — a medical condition that causes temporary hair loss — Latisse triggered moderate eyelash growth for more than 40 percent of participants. Research isn't conclusive, however. In another small study of people who have alopecia areata, Latisse wasn't an effective treatment for eyelash growth.

If you're concerned about the appearance of your eyelashes, talk to your doctor. He or she can help you weigh the pros and cons of using an eyelash-growing medication.

Does drinking water cause hydrated skin?


Although proper hydration is important for your overall health, it's not clear whether drinking extra water affects skin hydration in healthy people.

Skin is made up of three layers — the outer layer (epidermis), the underlying skin (dermis) and the subcutaneous fat tissue. 




If the outermost layer of the epidermis doesn't contain enough water, skin will lose elasticity and feel rough. 

Despite this connection, however, there's a lack of research showing that drinking extra water has any impact on skin hydration or appearance.

If you're looking to maintain hydrated skin, there are steps you can take, including:

Avoid exposure to dry air

Avoid prolonged contact with hot or chlorinated water

Use a gentle cleanser instead of soap

Avoid using skin care products that contain alcohol

Moisturize immediately after a bath or shower and regularly throughout the day

Use a humidifier

Are tanning beds safer than natural sunlight?


Tanning beds don't offer a safe alternative to natural sunlight.

Exposure to ultraviolet (UV) radiation damages your skin, whether the exposure comes from tanning beds or natural sunlight. 


This damage increases the risk of skin cancer and premature skin aging. 

In fact, tanning beds emit UVA rays — which might increase the risk of melanoma, the deadliest form of skin cancer.

If you'd like the golden glow of a tan without exposure to damaging UV radiation, consider using a sunless tanning product. 

Is sunscreen from last year still good? When does sunscreen expire?


Sunscreens are designed to remain at original strength for up to three years. This means that you can use leftover sunscreen from one year to the next.

Some sunscreens include an expiration date — a date indicating when they're no longer effective. Discard sunscreen that is past its expiration date. If you buy sunscreen that doesn't have an expiration date, write the date of purchase on the bottle. Also, discard sunscreen that is more than 3 years old, has been exposed to high temperatures or has obvious changes in color or consistency.

Keep in mind, however, that if you use sunscreen generously and frequently, a bottle of sunscreen shouldn't last from one year to the next. Generally, a liberal application is 1 ounce (30 milliliters) — the amount in a shot glass — to cover all exposed parts of the body. If you have a 4-ounce (118-milliliter) bottle, you'll use about one-fourth of it during one application.

To maximize protection, use a broad-spectrum sunscreen with an SPF of at least 15. The American Academy of Dermatology recommends using a broad-spectrum sunscreen with an SPF of 30 or more. Apply sunscreen generously 20 to 30 minutes before going outdoors and reapply about every two hours — or more often if you're swimming or sweating. Be sure to rub the sunscreen in well.

Tattoos: Understand risks and precautions


Tattoos might 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. Before you get a tattoo, make sure you know what's involved. Also, be certain that tattooing is the right decision for you.


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 — 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, green, yellow and blue dyes — can cause allergic skin reactions, such as an itchy rash at the tattoo site. This can occur even years after you get the tattoo.

Skin infections. A skin infection — which might cause redness, swelling, pain and a pus-like drainage — is possible after tattooing.

Other skin problems. Sometimes bumps called granulomas form around tattoo ink. Tattooing can also lead to keloids — raised areas caused by an overgrowth of scar tissue.
Bloodborne diseases. If the equipment used to create your tattoo is contaminated with infected blood, you can contract various bloodborne diseases — including tetanus, hepatitis B and hepatitis C.


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

Medication or other treatment — including possible removal of the tattoo — might be needed if you experience an allergic reaction to the tattoo ink or you develop an infection or other skin problem near a tattoo.


Make sure you're ready

Before you get a tattoo, ask yourself whether you truly want to invest in permanent body art. If you're unsure or worried that you might regret it someday, give yourself more time to think about it. Don't allow yourself to be pressured into getting a tattoo, and don't get a tattoo if you're under the influence of alcohol or drugs.

If you decide to go ahead with the tattoo, choose the location of the tattoo carefully. Consider whether you want the tattoo to be visible or hidden under clothing. Also remember that weight gain — including pregnancy weight gain — might distort the tattoo or otherwise affect its appearance.

Insist on safety precautions

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

Who does the tattooing? Don't attempt to tattoo yourself or allow an untrained friend to do 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 the needle and tubes from sealed packages before your procedure begins. Any pigments, trays or 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 between customers. 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.

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. While showering, avoid direct streams of water on the newly tattooed skin. 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.

Avoid swimming. Stay out of pools, hot tubs, rivers, lakes and other bodies of water while your piercing is healing.
Choose clothing carefully. Don't wear anything that might 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 might 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.
