Why does my neck look so much older than my face?

Why does my neck look like it is ageing twice as fast as the rest of me, and what can I do about it?

Neck skin tends to age faster than almost any place else on the body, said Dr Theodora Mauro, a professor of dermatology at the University of California, San Francisco.

The skin on your neck is particularly vulnerable to damage, she said. Poor posture, insufficient skincare, sun exposure and the natural weakening and decline of your neck muscles can all lead to accelerated ageing.

The skin on your neck also does not heal as well as it does elsewhere on the body because the skin there is less durable and has fewer stem cells and other structures that help repair it, said Dr Katie Given, a board-certified dermatologic surgeon in the Bay Area, who has written about skin ageing in the lower face and neck.

When it comes to slowing the ageing process for neck skin, she said, “the trick is prevention, prevention, prevention”.

Your neck needs sun protection

“Sun is your neck’s enemy,” Dr Mauro said. Many signs of ageing on the neck can be traced back to sun exposure.

When your skin is exposed to even a little sunlight, she explained, ultraviolet A waves reach the dermis, or the skin’s inner layer, and damage the cells that are responsible for producing collagen and elastin.

Collagen and elastin are two proteins that are essential for keeping your skin’s structure intact, said Dr Oma Agbai, an associate clinical professor of dermatology at UC Davis Medical Centre.

“Collagen helps to maintain firmness of the skin, and elastin helps it resume its original shape after it has been stretched,” she said.

The dermis, which comprises these proteins, tends to be thinner on the neck compared with other parts of the body, like the face and the upper arms, she added.

Prolonged exposure to the sun can lead to a “more crepey and more wrinkled” appearance, as well as skin discolouration and sunspots, Dr Agbai said.

People often forget to use sunscreen on their necks, Dr Mauro said, but protecting that area is just as important as protecting the rest of your body.

She recommended using a moisturising sunscreen with an SPF of at least 30 every day. She added that one should apply it liberally all over one’s neck and, if one is outside, reapply periodically throughout the day.

Treat your neck as well as you treat your face

People tend to lavish attention and care on their faces, Dr Agbai said, regularly applying serums, moisturisers and more.

Necks, on the other hand, do not tend to get much love. People should be including that area in their skincare routines, she said, applying products all the way down to their necks.

As people grow older, their skin loses some of its capacity to retain moisture, Dr Mauro said. The skin on their necks becomes dry, dull and less smooth. So, make sure you use a moisturiser both morning and night, she said, and avoid using alcohol-based skincare products on your neck as they are likely to dry your skin out even more.

Many soaps contain ingredients called surfactants that also dehydrate the skin, she said, and products like Ivory bar soap have alkaline ingredients, such as sodium tallowate, that throw off the skin’s pH levels and moisture barrier.

If a product leaves your skin looking and feeling dry, that might be a sign for you to switch to something different.

To improve your skin’s firmness, Dr Given added,

consider trying a lotion or serum with retinoids,

which can help stimulate collagen production with regular use.

Beware of “tech neck”

Another factor that contributes to an older-looking neck is “tech neck”, or the tendency to slouch and look down when using a laptop or mobile device, Dr Agbai said.

In addition to causing neck pain and strain, this posture also scrunches up your skin. And if you hunch over like that for hours, you are going to develop horizontal lines on your neck and under your chin, she said.

To prevent neck lines from forming or deepening, position your computer and phone so you are not bending and craning your neck for prolonged periods of time, Dr Mauro said. She noted, however, that changing your posture will not do anything to improve existing lines.

Aside from following the best practices above, it is important to avoid smoking, which can damage the skin, and maintain good health overall, Dr Mauro said. NYTIMES
