At Bella Complexion, we believe education is an important part of supporting your skin health. One question we’re often asked is:

“What exactly is oxidative stress?”

If you’ve ever wondered about it, you’re not alone. Let’s walk you through the basics, the science, and how small lifestyle habits can support your skin and overall wellness.

What is Oxidative Stress?

Oxidative stress occurs when there’s an imbalance between free radicals and antioxidants in the body. Free radicals are unstable molecules that can form naturally during normal metabolic processes such as inflammation and exercise. However, they can also be influenced by external factors like pollution, sun exposure, and certain chemicals.

Antioxidants, on the other hand, are molecules that help neutralise free radicals. When your body has more free radicals than it can handle, this imbalance is referred to as oxidative stress.

How Does It Affect the Body?

Free radicals play a role in many biological processes. However, when present in excessive amounts, high levels of oxidative stress have been studied in relation to:

• Age-related changes in skin appearance
  
• Cellular function
  
• Inflammatory responses
  
• Long-term health conditions

More research is being done to better understand the full role oxidative stress plays in long-term health. It’s important to note that these are associations—not guarantees—and individual experiences may vary.

What Increases Oxidative Stress?

While oxidative stress is a natural part of life, some environmental and lifestyle factors may contribute to it. These include:

• Smoking or exposure to second-hand smoke
• Pollution and UV exposure
• Poor diet (high in processed foods or added sugar)
• Excessive alcohol intake
• Lack of sleep
• Chronic psychological stress
• Certain chemicals in household products or pesticides

Can You Reduce the Impact of Oxidative Stress?

Although oxidative stress can’t be completely avoided, supporting your body through healthy lifestyle choices may help balance its effects. Here are a few science-backed habits that may support overall wellbeing:

1. Eat a Colourful, Balanced Diet

Include a variety of antioxidant-rich fruits and vegetables in your daily meals. These foods are known to contain naturally occurring antioxidants, which are widely studied for their potential role in overall wellbeing:

• Leafy greens (like spinach or kale)
• Berries (blueberries, strawberries)
• Tomatoes
• Carrots
• Broccoli
• Citrus fruits
• Olives
  

Other sources of dietary antioxidants may include:

• Garlic and onions
• Green tea
• Spices like turmeric
• Nuts, seeds, and fish (sources of omega-3)
• Vitamins C and E (through food or as recommended by your healthcare provider)

2. Exercise in Moderation

Regular physical activity is associated with overall health benefits. Maintaining a routine that suits your lifestyle and fitness level is often encouraged. It’s best to adopt a balanced routine that works for your fitness level and lifestyle.

3. Prioritise Sleep

Adequate sleep is important for general wellbeing and is recognised as supporting a variety of bodily functions.

4. Limit Exposure to Harmful Substances

When possible, limit exposure to environmental pollutants, cigarette smoke, harsh chemicals, and unnecessary radiation. Using sunscreen daily is recommended as part of general sun safety practices.

5. Manage Stress Levels

Chronic stress may contribute to imbalances in the body. Mindfulness, relaxation techniques, and regular self-care may help promote emotional and physical wellbeing.

6. Avoid Overeating and Excess Alcohol

Overeating or consuming excessive alcohol may increase free radical production. Eating mindfully and drinking in moderation is often recommended as part of a balanced lifestyle.

Final Thoughts

Oxidative stress has been studied in relation to skin and general wellbeing. More research is needed to fully understand these associations. While we can’t eliminate free radicals altogether, we can support the body through informed choices.
