Definition
Carotenoids are natural pigments that give fruits and vegetables red, yellow, and orange colours.
Expanded Explanation
Carotenoids are a group of over 600 organic compounds found in plants, algae, and photosynthetic bacteria. They play an essential role in photosynthesis and serve as antioxidants, protecting cells from damage caused by free radicals.
The human body can convert carotenoids into vitamin A, which promotes healthy vision, immunity, and overall growth and development. This conversion process is essential for maintaining good health. Additionally, carotenoids are found in many fruits and vegetables, making incorporating them into a healthy diet easy.
Types of Carotenoids
The most common carotenoids include beta-carotene, alpha-carotene, lutein, zeaxanthin, and lycopene. These compounds have varying health benefits and can be found in different food sources.
Carotenoids in Skincare
Carotenoids have antioxidant properties that can benefit the skin by neutralizing free radicals, reducing inflammation, and protecting against UV damage. Some skincare products incorporate carotenoid-rich ingredients to promote skin health.
Examples
Example 1: Beta-carotene, a carotenoid found in carrots and sweet potatoes, supports healthy vision and immune function.
Example 2: Lycopene, a carotenoid in tomatoes, offers antioxidant benefits and helps protect the skin from sun damage.

Vitamin A: Vitamin A encompasses a group of fat-soluble compounds crucial for maintaining healthy skin, vision, immune system function, and overall growth and development. It is vital in various biological processes, such as cell growth, vision, and immune function.
It has antioxidant properties that help safeguard cells from damage caused by free radicals. There are two primary types of Vitamin A: Retinol and carotenoids.
Retinol, the preformed Vitamin A, is found in animal-based foods like liver, eggs, and dairy products. In contrast, carotenoids and provitamin A are abundant in plant-based foods such as carrots, spinach, and sweet potatoes.
Antioxidants: Antioxidants neutralize free radicals, protecting the skin and body from oxidative stress. This stress can cause cell damage, inflammation, and aging. Maintaining overall skin health and a youthful appearance requires antioxidants to combat the harmful effects of free radicals.
These unstable molecules can cause cell damage, premature aging, inflammation, and other skin issues. Various natural sources contain antioxidants, including fruits, vegetables, and certain skincare products.

Carotenoids: Linus Pauling Institute: Carotenoids, synthesized by plants, are pigments that impart yellow, orange, and red colours. Standard in the North American diet include α-carotene, β-carotene, β-cryptoxanthin, lutein, zeaxanthin, and lycopene.
Notably, the body can convert provitamin A carotenoids like α-carotene, β-carotene, and β-cryptoxanthin into retinol (vitamin A). However, lutein, zeaxanthin, and lycopene do not provide vitamin A activity.
Carotenoids: National Institutes of Health (NIH): The human diet includes two primary sources of vitamin A: preformed vitamin A (retinol and retinyl esters) and provitamin A carotenoids. Animal-based foods like dairy products, eggs, fish, and organ meats contain preformed vitamin A.
Provitamin A carotenoids plant pigments, are converted into vitamin A in the intestine. The primary provitamin A carotenoids in the human diet are beta-carotene, alpha-carotene, and beta-cryptoxanthin. Other carotenoids like lycopene, lutein, and zeaxanthin, present in food, do not convert into vitamin A and have different biological activities.
