As the seasons change, many people notice their skin looking dull and tired. Dry air, busy schedules, and shifts in weather can leave the complexion feeling sensitive and lackluster. While thick, calming topical products can help soothe the skin, increasing antioxidant intake is another key strategy. Antioxidants fight free radicals, calm inflammation, and improve the overall appearance of tired skin by supporting it from the inside out.
Three specific antioxidants stand out for their ability to transform dull skin into a glowing complexion.
Vitamin C and Vitamin E
Vitamin C and Vitamin E are well-known for their role in collagen production. Vitamin C is a cofactor in the collagen production process, as skin cells rely on it to synthesize the protein. Vitamin E protects against collagen cross-linking, a process where collagen becomes hard and stiff, leading to skin aging. For those dealing with tired, sagging, or aging skin, these two vitamins are important additions to a routine.
These vitamins work together to make each other stronger. One study found that vitamin E increases vitamin C’s effectiveness eightfold. In turn, vitamin C regenerates vitamin E after the latter neutralizes free radicals, further reducing oxidative stress on cell membranes. Both are powerful antioxidants that help reduce free radical damage and ease inflammation. Vitamin C has been shown to improve overall skin quality and tone by reducing hyperpigmentation, brightening the complexion, decreasing moisture loss, and fighting against UV-induced damage.
Astaxanthin
Astaxanthin is sometimes called the “King of the Carotenoids” due to its effectiveness as an antioxidant. This nutrient is found in some types of red algae and marine life, such as salmon and crabs. While it appears in skin care products, it may be best used as a supplement, as research shows it can address several skin conditions from the inside out.
One study found that astaxanthin improved skin wrinkles, age spot size, and skin texture. In a double-blind clinical trial, subjects reported significant improvement in moisture levels, especially around the eyes, along with better elasticity and overall tone. Another double-blind study found that it can help the skin’s ability to retain water, thereby improving moisture and radiance.
Blood Orange Extract
Blood orange extract is a lesser-known superfood, but new research highlights its potential to improve the complexion. A randomized, double-blind, controlled study found that participants who took 100 mg daily saw a statistically significant increase in skin radiance. The increase was 9.2% after 14 days and 18.5% after 56 days.
The same study also found that the extract helped with wrinkle depth. Researchers measured the participants’ mean deepest wrinkle before, during, and after supplementation. They found that wrinkle depth decreased by 6.9% by the end of the study.
Increasing antioxidant intake is a reliable way to address dullness. These free-radical fighters can improve skin from the inside out, allowing the complexion to glow. While it is good to get a variety of antioxidants through diet, these options are among the most effective. If dietary intake is insufficient, supplementation may be considered.
