The Science of Skin Defense

Your skin is a remarkable armour under continuous assault from external stressors and environmental aggressors. When its defenses are compromised, your skin is robbed of precious vitality. This is the ever-present threat of free-radical damage.

Nature’s potent defenders, antioxidants are the unsung heroes of skin health. Antioxidants work tirelessly to neutralize harmful free radicals in a relentless barrage from pollutants, toxins and radiation. Advancements in dermatology and skin care science have paved the way for a deeper understanding of how antioxidants work, and to formulate them into effective skin care products to harmoniously defend, fortify, and rejuvenate your skin.

Whether you're a skin care enthusiast, a seeker of radiance, or simply curious about the meaning of phrases like free radicals, oxidative stress, or HEV light exposure, read on to unleash the power of antioxidant defenders, the vital elements in skin health and vitality.

Thieves and Troublemakers

In the pursuit of radiant and healthy skin, an often-overlooked key factor is the role of free radical damage. These microscopic miscreants, known as free radicals, are reactive molecules that can wreak havoc on your skin cells. From premature aging to uneven skin tone to DNA damage, their effects can be far-reaching.

Free Radicals

Free radicals are thieves and troublemakers. They’re highly reactive and chemically unstable. They have an unpaired electron, which makes them eager to steal an electron from other molecules to become stable. This theft can cause serious cell disruption.

Internally, free radicals are a natural byproduct of various cellular processes in the body. While the body has mechanisms to neutralize and manage these free radicals, problems occur when there’s an imbalance between the production of free radicals and the body's ability to counteract them.

External factors like HEV (high-energy visible) light, pollution, toxins, and smoking can also create free radicals and contribute to this imbalance between attackers and defenders.

When there are too many free radicals and not enough neutralizers to stop them, this imbalance can have harmful effects in our cells, including our skin cells. When free radicals damage skin cells, this can lead to problems like premature aging, DNA damage, and chronic inflammation.

HEV Light

We’re hearing more and more about blue light filters. They’re available for your eyeglasses, your computer monitor, your smartphone’s screen protector, but what about for your skin?

Blue light is also known as high-energy visible (HEV) light. It's part of the natural spectrum of sunlight and is also emitted by indoor lighting and digital devices, like smartphones, computers, and LED screens. While blue light is a natural component of sunlight and plays a role in regulating your circadian rhythm (sleep cycle), excessive and prolonged exposure to artificial sources of blue light can have negative effects on your eyes and skin.

While blue light itself is not inherently harmful in the doses we encounter in our daily lives, prolonged and frequent exposure to digital screens can lead to the generation of free radicals in the skin, and can cause disruptions to our circadian rhythm, the internal clock that regulates our sleep-wake cycle and other biological processes.

Impact on Skin Health

Here's how free radicals and blue light exposure can impact your skin:

Oxidative Stress: Oxidative stress occurs when excess free radicals overwhelm the body's antioxidant defenses. This oxidative stress can damage important cellular components (like DNA, lipids, and proteins), which in turn contributes to various health issues. Oxidative stress in the skin accelerate premature aging, contributing to devitalization, wrinkles, and a loss of skin elasticity.

Collagen Breakdown: Free radicals damage collagen and elastin fibers (essential for maintaining skin's firmness and elasticity), and blue light exposure has been shown to inhibit collagen production. This destruction combined with inhibited regeneration of collagen gradually contributes to diminished elasticity, the formation of fine lines and wrinkles, loss of facial volume, and sagging skin.

Inflammation: Inflammation is the body's response to damage and free radicals trigger an inflammatory response in the skin. Chronic inflammation can manifest as redness, swelling, and irritation, contributing to skin sensitivity and discomfort.

Hyperpigmentation: Free radicals, blue light, and inflammation are linked to an increase in the production of melanin, the pigment responsible for skin color. This excess melanin production can lead to uneven skin tone and the development of dark spots or hyperpigmentation.

DNA Damage: Free radicals can damage the DNA within skin cells. This DNA damage can interfere with proper cell function and repair mechanisms, potentially leading to the development of skin cancers.

Weakened Skin Barrier: Oxidative stress can compromise the skin's natural barrier function. Like cracks in our armour, a compromised barrier allows essential moisture to escape more easily, and leaves the skin more vulnerable to environmental irritants.

Disruption of Circadian Rhythm: Overexposure to blue light, especially during evening hours, can disrupt the body's natural circadian rhythm, which is responsible for regulating sleep-wake cycles. Not sure why this is important? While you sleep, your body enters a state of rest and repair. This is when your skin's cells work hard to repair any damage that occurred during the day. During sleep, collagen is replenished more quickly and skin cells regenerate more efficiently. Sleep also increases blood flow, which means your skin receives more oxygen and nutrients. This improved circulation contributes to a healthier complexion and a natural glow.

Guardians of Skin Health

Antioxidants are the superheroes that neutralize free radicals and protect our cells from their harmful effects. Antioxidants are molecules that can neutralize free radicals by donating an electron without becoming unstable themselves. Antioxidant compounds are found in various natural sources, such as fruits, vegetables, and botanicals. Common antioxidants used in skin care include vitamins C and E, beta-carotene, resveratrol, and various botanical extracts. These antioxidants help protect the skin from oxidative stress, support collagen production, reduce inflammation, and promote overall skin health.

Antioxidant skin care products come in a variety of formulations, ranging from serums and creams to oils and masks. They work on multiple levels to provide comprehensive protection and rejuvenation. When applied topically, antioxidants infuse the skin with a dose of much-needed protection, helping to maintain its resilience and youthful appearance. They assist in repairing the skin's natural barrier, reducing inflammation, and promoting skin elasticity.

To incorporate antioxidants into your skin care routine, look for products containing ingredients like vitamin C, vitamin E, niacinamide, green tea extract, and resveratrol, among others. Vitamin C is renowned for its brightening effects and vitamin E is prized for its moisturizing and soothing qualities. Green tea extract and niacinamide offer anti-inflammatory properties. These potent ingredients work synergistically to create a protective barrier against the oxidative stress induced by factors like UV radiation, pollution, and blue light emitted from screens.

Additionally, practicing good screen hygiene by taking breaks from digital devices, using blue light filters or screen protectors, and maintaining a consistent skin care routine that includes sun protection can all contribute to minimizing the impact of blue light on your skin.

Integrating antioxidant-rich products into your daily regimen can yield transformative results. Whether you're aiming to diminish the appearance of fine lines, counteract the effects of pollution, or reclaim your skin’s vitality and glow, antioxidants offer an effective means to fortify your skin's defenses.
