Dark chocolate has long been hailed for its potential health benefits. In keeping with the anti-ageing themes we know our patients at The Doctors Laser Clinic like to read about, we took a closer look. We wanted to see what compounds it contains and how they may help the skin and body. The question we wanted to answer is: “Can incorporating dark chocolate into your diet enhance your skincare routine and help support your skin’s health and longevity?”
The Composition of Dark Chocolate
Table of Contents
Antioxidants and Flavonoids
Dark chocolate is rich in antioxidants, particularly flavonoids. These are a group of plant chemicals known for their powerful antioxidant properties. These flavonoids help combat free radicals in the body—unstable molecules that can damage cells and contribute to ageing and disease. By neutralising these free radicals, the antioxidants in dark chocolate may help protect the skin from oxidative stress and maintain more of a youthful appearance.Essential Vitamins and Minerals
As well as antioxidants, dark chocolate contains essential-in-the-body minerals. It is a good source of magnesium, which helps maintain healthy skin by supporting proper hydration and preventing dryness. Iron, another vital mineral found in dark chocolate, is involved in healthy blood circulation, and nourishing the skin. Copper, also present in dark chocolate, aids in the production of collagen and elastin, the proteins we keep going on about that keep the skin firm and elastic.The Importance of Cocoa Content
The health benefits of dark chocolate are most potent in varieties with a high cocoa content. Look for dark chocolate that contains at least 70% cocoa to ensure you are getting the maximum benefits. The higher cocoa content means more antioxidants and less sugar, making it a healthier choice overall. When selecting dark chocolate, aim for organic and ethically sourced options to avoid unnecessary additives and support sustainable practices. The darker the better mantra has a limit, as far as taste goes. Having tried 100% cocoa chocolate, it is not really edible on its own.Health Benefits of Dark Chocolate for Skin Health
Protection Against UV Damage and Free Radicals
Some surprising and interesting research has shown that the flavonoids in dark chocolate can help protect the skin against damage from ultraviolet (UV) rays. These compounds improve the skin’s resistance to UV-induced stress by increasing blood flow to the skin and improving its density and hydration. Regular dark chocolate consumption may enhance your skin’s natural defence mechanisms, reducing the risk of sunburn and long-term sun damage.Dark Chocolate may help to Improve Skin Hydration and Thickness
The hydrating properties of dark chocolate can help maintain and improve the skin’s moisture levels. Flavonoids increase blood flow to the skin, which helps to keep it hydrated and supple. Studies have also found that consuming dark chocolate can increase skin thickness, which contributes to a resilient complexion.Improve Blood Flow and Detoxification
The bioactive compounds in dark chocolate, such as theobromine and caffeine, can improve blood circulation. Enhanced blood flow ensures that oxygen and essential nutrients are effectively delivered to skin cells, promoting detoxification and healthy skin cell function. This improved circulation goes towards giving your skin a natural, healthy glow.
Dark Chocolate’s Skin Benefits
Increasing Blood Flow
Nitric Oxide Production
Flavanols in dark chocolate stimulate the production of nitric oxide (NO) in the endothelium, the inner lining of blood vessels. NO is a potent vasodilator that relaxes and widens blood vessels, improving blood flow. Enhanced blood flow ensures that more oxygen and nutrients are delivered to skin cells, promoting healthier skin and aiding in the removal of metabolic waste.Improved Microcirculation
Flavonoids improve capillary function and density, enhancing microcirculation within the skin. This consistent supply of nutrients and oxygen is essential for maintaining a youthful and vibrant complexion.Improving Skin Density and Hydration
Collagen Synthesis
Flavonoids stimulate collagen production, a structural protein that provides skin strength and elasticity. This process is crucial for maintaining skin density and preventing fine lines and wrinkles. Copper in dark chocolate supports collagen and elastin fibre cross-linking through lysyl oxidase, vital for skin firmness and elasticity.Reduction of Inflammation
Chronic inflammation contributes to skin ageing. Flavonoids’ anti-inflammatory properties help reduce cellular inflammation, preventing collagen and elastin breakdown, thus maintaining skin integrity and thickness.Hydration and Barrier Function
Flavonoids enhance skin barrier function by increasing lipid production, crucial for maintaining hydration and protection against environmental stressors. Improved hydration reduces transepidermal water loss (TEWL), keeping the skin supple and resilient.Other Bioactive Compounds
Theobromine and Caffeine
These compounds in dark chocolate have what are known as vasodilatory effects. They contribute to improved blood flow and nutrient delivery to the skin. Theobromine also acts as a mild diuretic, reducing puffiness and improving skin tone.Magnesium
This is essential for skin hydration. Magnesium regulates sebum production, preventing dryness and maintaining the skin’s moisture balance.Consuming Dark Chocolate
Moderation
It’s not all roses. There is a bit of a downside – sugar and fat, both found in dark chocolate. There is also, along with the beneficial mineral content (e.g. zinc), a question mark over the amount of lead and cadmium chocolate contains. Regularly eating dark chocolate may push your toxin load over a safe level. An article about this issue can be read here. More food for thought. If you are going to take this seriously, seeking out brands that contain lower levels of heavy metals would be prudent. With regards to amounts, when discussing chocolate, you may hear nutritionists recommend 1 or 2 squares per day (20-30 grams), and some 2-4 squares (30-60 grams). This is what we read. Somewhere around these amounts should be enough to reap the benefits without overdoing it.
