Preventing skin aging: where to start?

When it comes to aging skin, we sometimes feel helpless or overwhelmed by a flood of products and promises. However, preventing the signs of aging is based on a few simple, prioritized principles. The challenge is knowing where to start—and in what order.

Many of the visible signs of aging can be prevented, since they depend on external factors that we can influence. Here are the key steps—from the most essential to the most complementary—for long-term skin care.

Intrinsic and Extrinsic Aging: What Is Inevitable, and What Is Not

Skin aging results from two processes. Intrinsic, or chronological, aging is linked to genetics and the passage of time: it is inevitable. Extrinsic aging, on the other hand, is caused by environmental factors and lifestyle: sun exposure, pollution, smoking, diet, and stress. However, it is this factor that has the greatest impact on the visible signs of aging.

A landmark study has estimated that sun exposure accounts for approximately 80% of the visible signs of facial aging. So there’s two pieces of good news: most visible signs of aging are caused by external factors, and these factors are largely preventable. This is precisely where prevention comes into play.

Step 1: Protect Your Skin from the Sun—the Most Important Step

Since the sun is the primary culprit, daily sun protection is, without a doubt, the most crucial step. It is also the most scientifically well-documented measure: a landmark randomized trial showed that regular use of sunscreen measurably slowed the appearance of visible signs of aging.

In practical terms, this means applying broad-spectrum sunscreen every morning, even on cloudy days. The PERS SPF 50+ Protection, with its invisible, non-sticky texture, is designed for daily use—which is essential for it to be effective. If you had to choose just one anti-aging step, this would be it.

Step 2: Boost Antioxidant Defenses

Sun exposure and pollution generate free radicals, which cause oxidative stress that damages the skin. To complement sun protection, it’s helpful to strengthen the skin’s antioxidant defenses. Vitamin C is a key active ingredient here: it helps neutralize these free radicals, aids in collagen synthesis, and supports a radiant complexion.

Apply in the morning before sunscreen, the 10% PERS Vitamin C Serum acts as an internal shield, working in a way that complements that of sunscreen. Sunscreen and antioxidants thus form the foundation of effective prevention.

Step 3: Stimulate cell renewal

Once the protective barrier is in place, you can take a more proactive approach by stimulating skin renewal. Retinol is one of the most extensively studied anti-aging ingredients: it promotes cell renewal and stimulates collagen production, which helps smooth the skin’s texture and reduce the appearance of wrinkles.

The 0.3% PERS Retinol Serum, which is highly tolerable, should be applied in the evening every other night, gradually increasing the frequency of use. It complements preventive care with a corrective action, while remaining suitable for even the most sensitive skin.

Healthy Lifestyle and Consistency: The Foundation of Prevention

Beyond skincare, a few basic habits can help maintain healthy skin over the long term.

• Support the skin barrier with proper hydration for more resilient skin.
• Get a good night's sleep, because the skin repairs itself mainly at night.
• Eat a balanced diet rich in antioxidants.
• Limit smoking and excessive sun exposure, which accelerate aging.

One final point matters more than anything else: consistency. Prevention is all the more effective when it starts early—ideally in your late 20s or early 30s—but it’s never too late to get started. It’s better to have a simple routine that you follow consistently than a collection of products that you use sporadically.

Key Takeaways

Most visible signs of aging are caused by external factors and are therefore largely preventable. To prevent these signs, follow these steps in order of importance: protect your skin from the sun every day—the most crucial step—boost your antioxidant defenses with vitamin C, and then stimulate cell renewal with retinol. All of this relies on a healthy lifestyle and, above all, consistency. Start with the most important step and stick with it: that’s the best strategy for skin that ages well.
