Defending the skin
Carotenoids
Carotenoids are natural pigments found in many fruits and vegetables, responsible for their yellow, orange and red colors.
beta-carotenoids
Among the best-known are beta-carotene, lycopene, lutein, zeaxanthin, and astaxanthin, each with specific and valuable properties for the body. In addition to playing an important role as natural antioxidants, carotenoids are increasingly recognized for their visible benefits on the skin, both in terms of protection and aesthetic improvement.
Cosmetics and nutrition are increasingly merging, and carotenoids are proving to be among the best allies for skin health, thanks to their dual aesthetic and functional action. It’s not just about preventing aging, but also deeply nourishing the skin, respecting its biological rhythms and enhancing its natural beauty.
What are carotenoids
Carotenoids belong to the family of fat-soluble phytonutrients, substances that dissolve in fats and, once ingested, are converted by the body into active compounds. For example, beta-carotene is a precursor to vitamin A, essential for cell renewal and maintaining healthy, radiant skin.
Being natural compounds, carotenoids are not produced by the human body, so it’s essential to consume them through diet or specific supplements.
Carotenoids and skin: a winning combination
Several scientific studies have shown that regular intake of carotenoids can have visible and measurable effects on skin health. Here’s how they work:
1. Antioxidant and anti-aging action
Carotenoids neutralize free radicals, unstable molecules that damage cells and accelerate skin aging.
Thanks to their antioxidant action, they help:
– Reduce fine wrinkles and loss of elasticity.
– Protect collagen and elastin, essential for firm skin.
– Improve the texture and overall appearance of the complexion.
2. Protection from UV rays
Among the most appreciated benefits of carotenoids is photoprotection. Compounds such as beta-carotene, lycopene, and astaxanthin are able to absorb some of the harmful UV rays, acting as a sort of “internal filter.” This does not replace external sunscreen, but enhances its effect from within, reducing damage from exposure and preventing sunburn, redness, and discoloration.
3. Even skin tone and a “healthy glow” effect
A regular intake of carotenoids, especially through a diet rich in fruits and vegetables, gives the skin a healthy, radiant complexion. This is the so-called “carrot effect,” due to the deposition of pigments in the dermis. This effect is perceived as more attractive than a sun-induced tan, as it indicates health and well-being.
4. Support against acne and inflammation
Some carotenoids, such as zeaxanthin and lutein, have anti-inflammatory properties, useful for sensitive skin, acne, or rosacea. They help calm redness and reduce the oxidative processes underlying many types of dermatitis.
The main carotenoids for the skin
– Beta-carotene: Found in carrots, pumpkins, apricots, and green leafy vegetables. It is the best-known and a precursor to vitamin A.
– Lycopene: Found in tomatoes, watermelon, and pink grapefruit. It is one of the most powerful antioxidants for skin.
– Astaxanthin: Obtained from red algae, it is among the most effective carotenoids for counteracting UV damage and reducing wrinkles.
– Lutein and zeaxanthin: Often associated with eye health, but also important for protecting the skin from blue light and pollution.
How to take them correctly?
Because they are fat-soluble, carotenoids should be consumed alongside sources of healthy fats for proper absorption: for example, extra virgin olive oil or nuts.
They can be consumed through a varied and colorful diet or through supplements, especially during periods of poor nutrition or increased demand (sun exposure, stress, pollution, smog). Taking sustained-release supplements improves absorption.
When is it usefull to integrate them?
– Year-round for city dwellers whose skin is stressed by smog and blue light.
– In spring and summer, to prepare skin for sun exposure and protect it from UV damage.
– In older age, to combat skin aging.
– For blemish-prone or sensitive skin, to take advantage of its calming and soothing properties.
What can alter carotenoid levels?
Several factors can affect the availability of carotenoids in the body:
– Diet low in fruits and vegetables
– Smoking and alcohol
– Exposure to environmental pollutants
– Prolonged stress
– Chronic medication use
All these factors increase oxidative stress and can reduce the effectiveness of natural carotenoids, making targeted supplementation beneficial. Carotenoids represent a true natural “internal” treatment for improving skin health and beauty. They work synergistically with a healthy diet, a balanced lifestyle, and good skincare. Incorporating these nutrients into your daily routine is a winning choice for more protected, radiant, and youthful skin, lasting longer.
