Long-lasting skin starts from within: Nutrition, sleep, and exercise as the keys to true regeneration

When I think of beautiful, healthy skin, I don’t think of perfection first. I think of radiance, of balance, of that certain glow that emerges when skin is healthy, both inside and out. 

In my daily work, I see how much lifestyle and skin condition influence one another. And I am convinced: true longevity begins in everyday life. It is not just creams or serums that keep our skin young. It is the interplay of nutrition, sleep, exercise, and how we treat ourselves. 

Nutrition – our skin feels what we eat 

I find you can tell when people eat a nutrient-rich diet. Well-nourished skin appears more vibrant, smoother, and plumper. Antioxidants from fresh fruits and vegetables protect cells from free radicals, while healthy fats and proteins form the foundation of the skin. Many forget that the skin is our body’s largest organ. It needs energy, just like our muscles or our heart. 

When we nourish it from within, it can regenerate better, and that is exactly the basis for true skin longevity. 

Sleep – the moment the skin breathes 

I often say to my patients: Sleep is the best anti-aging measure, and it costs nothing. 

Fascinating things happen at night: the skin repairs minor cellular damage, forms new structures, and retains moisture. If we don’t get enough sleep, it shows—not just in our eyes, but in our entire skin structure. It appears tireder, duller, and thinner. 

Good sleep is therefore not a luxury, but a biological necessity. While we rest, regenerative processes are activated that are directly linked to skin aging—exactly the mechanisms I described in my last blog post about the 12 Hallmarks of Aging. They are a wonderful example of how skin aging doesn’t just happen, but depends on many small cellular changes that we can actively influence. 

Exercise – energy that you can see on the skin 

I am not a fan of extreme programs. But I am convinced that exercise, in any form, strengthens the skin. When your circulation gets going, blood flow improves, cells are better supplied with oxygen, and waste products are transported away more quickly. 

You can see it: the skin looks rosier, more vital, more alive. 

Furthermore, exercise lowers stress levels, which is one of our skin's greatest enemies. Less cortisol means a stronger skin barrier, fewer inflammatory processes, and more balance. Longevity also means taking responsibility. I firmly believe that longevity has nothing to do with vanity. It means taking responsibility for yourself, and for your skin, too. 

Our daily diet, our rest phases, our exercise—all these are decisions that show on the skin. High-quality skincare can only reach its full potential when the body is on board, providing, among other things, the optimal conditions for retinol to exert its regenerative effect. That is why I view skin longevity as a symbiosis between science, habits, and awareness. 

When we start not just to care for our skin, but to understand it, something wonderful happens. It begins to work with us, not against us.
