Clinical findings point to vitamins C and E, astaxanthin and blood orange extract as nutrients that may help support radiance, elasticity and protection against oxidative skin damage.

A growing body of clinical evidence is drawing attention to four antioxidants that may help improve tired, dull and aging skin by targeting oxidative stress from within the body.
The nutrients — vitamin C, vitamin E, astaxanthin and blood orange extract — are being studied for their ability to help protect skin cells from damage caused by free radicals, which are produced through pollution exposure, ultraviolet radiation and normal metabolic processes. Researchers say those unstable molecules can contribute to collagen breakdown, inflammation, dryness, fine lines and premature aging.
The findings add to a broader shift in skin health research that looks beyond topical creams and serums and focuses on how nutrition affects the skin at the cellular level. Proponents of antioxidant-based skin support say consistent intake through food and supplementation may help improve complexion, elasticity and resilience over time.
Vitamin C remains one of the best-known nutrients for skin health because of its role in collagen production. Skin cells rely on vitamin C as a cofactor in producing collagen, the protein that helps maintain firmness and structure. Clinical studies have found that daily use of vitamin C formulations for at least three months improved both fine and coarse wrinkles on the face and neck.
Vitamin C also has anti-inflammatory properties. Research cited in the report found that topical vitamin C helped improve acne-related inflammation, reduced dark spots with little irritation and lowered acne lesion counts when applied twice daily compared with placebo.
Vitamin E works alongside vitamin C and is often studied for its role in helping protect skin from long-term sun damage and redness. The two nutrients are frequently described as complementary because they work through related antioxidant pathways and may strengthen the skin’s defense against environmental stress.
Astaxanthin, a red carotenoid found in marine organisms, has also emerged as a major focus in antioxidant skin research. The pigment gives salmon, lobster, shrimp and some other seafood their reddish color. Researchers describe astaxanthin as unusually potent because of its molecular structure, which allows it to penetrate deep into tissues and provide broad protection against oxidative stress.
Testing comparisons vary depending on the method used, but astaxanthin has been reported to show antioxidant activity far beyond vitamin C in certain assays, ranging from about 65 times stronger in ORAC testing to as much as 6,000 times stronger in singlet oxygen quenching tests. It has also been shown to cross the blood-brain barrier, giving it potential relevance beyond skin health, including protection for the eyes and brain from oxidative damage.
Blood orange extract is receiving attention as another skin-supportive ingredient. The extract contains vitamin C, flavonoids and anthocyanins, a group of plant pigments associated with antioxidant activity.
In a randomized, double-blind, controlled clinical study, participants who took 100 milligrams of blood orange extract daily had a 9.2% increase in skin radiance after 14 days and an 18.5% increase after 56 days. The same study reported a 6.9% reduction in wrinkle depth by the end of the trial.
The extract was also associated with improved elasticity, increasing by 5.9% after 14 days and 13.9% after 56 days. Researchers attributed those effects partly to vitamin C’s role in supporting collagen and elastin synthesis.
Dietary sources may help consumers increase intake of these antioxidants naturally. Vitamin C is found in citrus fruits, bell peppers and leafy greens. Vitamin E is commonly found in nuts, seeds and certain plant oils. Astaxanthin occurs naturally in salmon, rainbow trout, shrimp and lobster, with four ounces of sockeye salmon providing about 4.5 milligrams. Blood oranges provide vitamin C and antioxidant plant compounds, while concentrated blood orange extract is increasingly available in supplement form.
The report said consistency is important because visible improvements in clinical studies typically appeared after several weeks of regular use rather than immediately.
Researchers and health practitioners also advise caution before starting supplements. Astaxanthin is generally considered safe but may interact with blood pressure medications and drugs that affect blood sugar. Individuals with autoimmune conditions or those taking immunosuppressive medications are advised to consult a healthcare provider before use.
The findings suggest that skin health may be supported through a combined approach that includes nutrition, antioxidants and consistent care. While topical products remain widely used, evidence cited in the report indicates that vitamins C and E, astaxanthin and blood orange extract may help address aging-related skin changes by supporting collagen, reducing oxidative stress and improving radiance from within.
