1. Limit Sun Exposure

Although we need a limited amount of exposure without protection to the sun in order to produce Vitamin D, it's vital to avoid prolonged exposure. Dermatologists consistently emphasize that too much sun is a major cause of premature aging, leading to fine lines and sunspots. Even on cloudy days or if you spend most of your day indoors, you should use a sunscreen or a foundation with a high SPF factor, as UV rays can easily pass through glass windows. For the best protection, the American Academy of Dermatology recommends using a broad-spectrum sunscreen every single day.

2. Don't Smoke

Another major cause of premature skin aging is smoking. It's often surprising to see how many young women continue to smoke despite the dangers being well-documented for decades. Smoking restricts blood flow and depletes the skin of essential nutrients like oxygen. You can almost always identify a long-term smoker by the tell-tale lines around their mouth and forehead. If these young women could see how many deep wrinkles they'll likely have by the age of 40, they would probably give up smoking right away to save their skin's elasticity.

3. Too Little Sleep

Sleep gives the body the essential chance it needs to repair and regenerate itself. If you're constantly short on shuteye, your skin is going to suffer, appearing puffy or sallow. Interestingly, the position you sleep in could also contribute to premature aging. The best position for your skin is on your back, as sleeping on your face or side can cause "sleep lines" and wrinkles where your face is pressed against the pillow for hours. Research from the National Sleep Foundation shows that quality rest is a cornerstone of skin health.

4. Neglecting Hands & Neck

Stars who have undergone cosmetic surgery or advanced facial treatments such as skin peels often look much younger than their years in their face. However, their hands and neck almost always reveal their true age because these areas are often neglected. If you want to stay looking young for as long as possible, don't just focus on your face; give equal attention to your neck and hands. Moisturize them regularly and always apply sunscreen to these exposed areas, as they are just as vulnerable to the elements as your face.

5. Ample Antioxidants

As well as getting plenty of restorative sleep, your skin also needs the right fuel to keep it supple and strong. If you're eating a poor diet, it will eventually show in your complexion. Make sure that you're incorporating plenty of foods for glowing skin that are rich in antioxidants, which act against damaging free radicals.

Consider adding these antioxidant powerhouses to your daily meals:

Eating lots of fruit and vegetables, beans, and nuts—especially brightly-colored fruits like berries—provides the building blocks your skin needs to stay resilient against the aging process.

6. Not Cleansing

At the end of a long day, you might be tempted to leave your makeup on because you're too tired to remove it, or you might think that you don't need to cleanse because you haven't worn makeup that day. However, it only takes a couple of minutes to properly cleanse your face, and the benefits are worth it. If you leave makeup or daily grime on, your pores will get clogged, leading to breakouts and dullness. It's especially important to cleanse if you live in an urban area, as dirt and pollution particles will settle on your skin and cause oxidative stress.

7. Repetitive Movements

Do you rub your eyes frequently, squint because you've forgotten your sunglasses, or always drink through a straw? While they seem harmless, such repetitive movements may cause your skin to wrinkle prematurely by breaking down collagen in specific areas. Be aware of these subtle habits and try to catch yourself before they become permanent fixtures. Swapping a straw for a glass or remembering your shades can make a bigger difference than you might think!

With a few simple steps and consistent care, you can avoid showing the signs of aging too early and keep your skin looking vibrant. But don't worry too much about the fact that you're going to develop some lines one day; worrying itself can cause stress that shows on your face! Embrace the journey and take care of the skin you're in. What do you hope to be like when you're older? Are there any anti-aging secrets you swear by?
