Have you ever looked at someone your exact age and wondered why they look noticeably younger—or why you seem more tired, hollow, or aged than you feel on the inside? According to Dr. Amir Karam, a board-certified facial plastic surgeon and founder of KaramMD Skin, accelerated aging isn’t just about a few fine lines. It’s about deeper structural changes happening beneath the skin that can make some people age up to 10 times faster than others.
“When we talk about aging faster, it’s the difference between looking vibrant and rested versus dull, hollow, and older than your years,” Dr. Karam explains. Collagen breakdown, thinning skin, inflammation, oxidative stress, and slowed cell turnover all play a role—and many of these factors are driven by daily habits. The good news? Most of them are completely within your control.
Here are the seven biggest aging accelerators doctors say to ditch for good as we move into 2026.

1. Chronic Sun Exposure
If there’s one habit Dr. Karam calls the number one ager, it’s unprotected sun exposure. UV rays break down collagen, deepen wrinkles, trigger pigmentation, and thin the skin over time. Damage from tanning and sun exposure in your teens and 20s often shows up decades later. “Any conversation about aging has to start with sun exposure,” he says. Daily sunscreen isn’t optional—it’s foundational.
2. Poor Skincare Habits
Using nothing at all—or worse, the wrong products—can quietly damage your skin barrier and speed up collagen loss. Harsh cleansers, over-exfoliation, or skipping active ingredients altogether can leave skin vulnerable and inflamed. According to Dr. Karam, effective skincare isn’t about doing more; it’s about using the right products consistently.
3. Inconsistent Routines
Starting and stopping retinol, vitamin C, or antioxidants is like going to the gym for a week and expecting results. “You never see long-term progress,” Dr. Karam explains. Skin aging is continuous, so your routine needs to be consistent to counteract it. Daily use of proven actives helps support collagen production, cell turnover, and skin resilience over time.
4. Smoking and Alcohol
Smoking accelerates aging across the entire face, leading to deeper wrinkles, crepey skin, and a dull complexion. Alcohol, meanwhile, dehydrates the skin, weakens collagen, and increases inflammation. Together, these habits can push your skin far beyond what genetics alone would dictate, making you look older faster than expected.
5. Chronic Stress and Poor Sleep
Elevated cortisol from long-term stress acts “like acid for your skin,” says Dr. Karam. Pair that with inadequate sleep, and the effects are immediate—dullness, greyness, puffiness, and loss of glow. Over time, chronic stress and sleep deprivation accelerate internal aging, which inevitably shows up on your face.
6. A High-Sugar, Processed Diet
Sugar doesn’t just affect your waistline—it damages your skin through a process called glycation, which stiffens collagen fibers and leads to sagging, dullness, and uneven texture. Highly processed foods increase inflammation and oxidative stress, essentially “rusting” the skin from the inside out.
7. Ignoring Lifestyle–Genetic Interactions
While genetics play a role, Dr. Karam emphasizes that epigenetics—how your environment interacts with your genes—matters just as much. “Genetics loads the gun, but lifestyle pulls the trigger,” he says. Sun exposure, diet, sleep, stress, and skincare choices can either amplify or calm aging-related genetic tendencies.
The Bottom Line
Aging faster isn’t inevitable. According to Dr. Karam, skin aging is the one part of the aging process you have the most control over. Daily sunscreen, consistent medical-grade skincare, good nutrition, stress management, and healthy lifestyle habits can dramatically slow—and even partially reverse—visible aging.
As we head into 2026, the focus isn’t about chasing youth—it’s about avoiding unnecessary damage and supporting your skin so your reflection finally matches how youthful you feel inside.
