From sebum production balancing to skin brightening and collagen synthesis, the many forms of vitamin C in skin care provide a host of desired protection against many skin concerns. Citric Acid: A Twist of Natural Exfoliation Citric acid is a carboxylic acid with a twist. It contains a single hydroxyl group in both the α (alpha) and β (beta) positions. Because of its prominent role in the human metabolic process, citric acid is an important extract of citrus fruits. In the skin, it is an antioxidant and has been shown to reverse signs of photodamage and counter solar elastosis by encouraging collagen synthesis. As a natural keratolytic, it both encourages skin sloughing and an increase in healthy epidermal thickness and water-binding glycosaminoglycans. Because of citric acid's molecular size (six carbon chain), its skin "peeling" effect is very superficial, making citric acid a great component for all levels of skin preparedness. With many skin benefits, this citrus fruit extract can be used in formulations to encourage skin rejuvenation in nearly every skin type and condition. Flavonoids: The Protectors Flavonoids are a class of compounds found in citrus fruits that offer a range of protective benefits to the skin. They possess potent antioxidant and anti-inflammatory properties, which can help shield the skin from damage caused by environmental factors such as pollution and harmful ultraviolet (UV) rays. Hesperidin and naringin, two specific flavonoids found in citrus fruits, are known for their ability to contribute to improved blood circulation, which in turn can promote a healthier, more even-toned complexion. • Hesperidin—This bioflavonoid is found in high concentrations in citrus fruits. It has a great influence on skin health, especially in reducing inflammation. In addition to providing antimicrobial and antioxidant protection, it has been shown to enhance the skin's barrier function, which then leads to stimulating natural hydration and healthy skin cell production and differentiation. Additionally, it is an ingredient showing promise in stopping malicious cell development. It's a widely Initially, vitamin C was thought to hold only antioxidant value for the skin, but with research and clinical studies, we know the stabilization of ascorbic acid provides additional skin health benefits. • Traditional folk remedies—Throughout history, citrus fruits have been used in folk remedies for various skin conditions. For example, lemon juice was employed to address issues like acne, sunburn, and hyperpigmentation. THE CITRUS ALL-STARS There are several citrus fruit compounds that have been widely researched to support some of the inherited anecdotal elements we still use in modern skin care. Vitamin C: Skin Care's Little Darling Vitamin C is one ingredient that's extensively used in many of today's skin care products. The discovery and identification of vitamin C, or L-ascorbic acid, was less than 100 years ago. Albert Szent-Györgyi, a Hungarian biochemist, received a Nobel Prize in medicine in 1937 for the discovery of vitamin C and the description of oxidation, which had a profound impact on the approach to dermatology. Initially, vitamin C was thought to hold only antioxidant value for the skin,
