Citrus bioflavonoids and sun protection -
When vitamin C is present alongside bioflavonoids, it is believed to create a synergistic effect, meaning that their combined action is greater than the sum of their actions.
This synergy is particularly notable in terms of enhancing vitamin C absorption and bioavailability in the body. The presence of bioflavonoids is thought to improve the absorption of vitamin C in the intestines by slowing down its breakdown and enhancing its transport across the intestinal lining.
This leads to better retention of vitamin C in the bloodstream, allowing the body to make more efficient use of this essential nutrient. One of the most well-known bioflavonoids that often accompanies vitamin C is hesperidin, commonly found in citrus fruits like oranges and lemons.
Hesperidin, along with other flavonoids like quercetin and rutin, has been shown to support the antioxidant activity of vitamin C and protect it from oxidation, ensuring its stability and effectiveness.
Finally, it is important to note that bioflavonoids themselves possess antioxidant properties, contributing to the overall antioxidant capacity of vitamin C-rich foods.
They work in harmony with vitamin C to scavenge free radicals and protect cells from oxidative damage, which is particularly important during periods of increased oxidative stress. Thus, due to its re-enforcement of the benefits of vitamin C, consuming vitamin C with hesperidin provides further protection against UV-induced damage and inflammation in the skin.
UV radiation consists of UVA and UVB rays, both of which can harm the skin and contribute to photoaging and increased risk of skin cancer.
While sunscreen forms a physical or chemical barrier to absorb or reflect UV rays, vitamin C works differently. It doesn't absorb UVA or UVB rays directly, but it can help mitigate the damage caused by UV exposure. Vitamin C's antioxidant properties neutralize free radicals generated by UV radiation, reducing inflammation, DNA damage, and collagen breakdown in the skin.
Hyperpigmentation, characterized by dark spots or patches on the skin, is a common concern caused by sun damage and hormonal changes. Vitamin C has been shown to have skin-lightening properties, helping to fade hyperpigmentation and even out skin tone.
By inhibiting the production of melanin, the pigment responsible for dark spots, vitamin C can help brighten the skin and reduce the appearance of sunspots. The skin has a remarkable ability to heal itself, but it can benefit from additional support.
Vitamin C plays a vital role in promoting the skin's natural repair processes, particularly after sun damage. By stimulating collagen synthesis and supporting the production of new skin cells, vitamin C helps expedite the healing of sunburns and other forms of UV-induced skin damage.
Additionally, vitamin C's anti-inflammatory properties help reduce redness and soothe irritated skin. To harness the protective benefits of vitamin C, it's essential to incorporate it into your skincare routine. Whether through topical application or internal consumption, vitamin C can enhance your skin's resilience and defence against sun damage.
Topical vitamin C serums or creams are a popular choice for delivering this antioxidant directly to the skin. When applied topically, vitamin C can penetrate the skin and provide localized protection against UV damage.
Look for serums or creams containing L-ascorbic acid, the most active and researched form of vitamin C. While vitamin C can provide additional protection against sun damage, it's important to note that it should not replace sunscreen. Instead, vitamin C should be used in conjunction with sunscreen for comprehensive sun protection.
Apply a broad-spectrum sunscreen with a high SPF before applying vitamin C serum or cream. The sunscreen will create a barrier against UV rays, while vitamin C will provide antioxidant support and further minimize the harmful effects of sun exposure.
In addition to topical application, consuming foods rich in vitamin C is crucial for maintaining optimal levels in the body.
Citrus fruits, such as oranges and grapefruits, are well-known sources of vitamin C. However, other fruits like kiwis, strawberries, and papayas, as well as vegetables like bell peppers and broccoli, are also excellent sources.
Including these foods in your diet can provide a steady supply of vitamin C, supporting overall skin health and sun protection from within. However, during periods of prolonged sun exposure, the body's natural reservoir of vitamin C may become depleted due to the continuous battle against oxidative stress.
As a result, the body may require additional vitamin C from external sources to ensure an optimal level of protection against skin damage. Higher levels are easier to achieve with supplementation. Supplementation with vitamin C that contains bioflavonoids is one of the best ways of helping support vitamin C status during periods of stress.
As we strive to protect our skin from the damaging effects of the sun, incorporating vitamin C into our skincare routine becomes increasingly important. With its antioxidant properties, collagen-boosting abilities, and potential to mitigate the harmful impact of UV radiation, vitamin C stands as a powerful ally in maintaining healthy, radiant skin.
Whether through topical application or dietary consumption, vitamin C can enhance the skin's natural defences, offering an extra layer of protection against sun damage. So, don't forget to reach for that vitamin C serum, savour those citrus fruits, and embrace the power of this remarkable nutrient in safeguarding your skin from the sun's rays.

Are recommended daily allowances for vitamin C adequate?. Compared with the model group, there was a significant improvement in the changes in the collagen fibers in the skin tissue of the mice in the LPF-treated group, the degree of collagen fiber damage was reduced, and the arrangement was relatively neat.
During the experiment, the mice were irradiated with UVB for 4 weeks, which clearly demonstrated continuous skin damage sustained by UVB, and simulated the damaging effect of UVB on the skin in an objective and specific manner.
UVB radiation causes many changes such as damage to the skin's epidermal structure, rupture of collagen fibers, and accompanying infiltration of inflammatory cells. After UVB radiation, epidermal keratinocytes release a large amount of inflammatory mediators and chemokines, such as IL-1, IL-6, IL, and TNF-α, and inflammatory cell hyperplasia occurs in the later stage of inflammation.
The application of LPF decreases the epidermal inflammation in mice with UVB-induced skin damage. The skin's own antioxidant system efficiently removes low levels of reactive oxygen species ROS. However, excessive exposure to UVB causes large amounts of ROS to be produced, resulting in oxidative stress.
SOD is an active substance that protects beneficial free radicals and maintains their balance in living systems, thereby effectively blocking oxidative stress damage.
In the current study, SOD activity in the LPF-treated groups significantly increased, indicating that LPF increased the SOD activity in mice. As an endogenous oxygen scavenger, CAT effectively prevents excessive cellular oxidation and decreases the oxidative damage in cells.
MDA effectively reflects the degree of lipid affected by ROS in the body, and indirectly reflects the cell damage. Nrf2 is a key factor in cell defense against oxidative stress, and Nrf2 is also an essential regulator for inducing phase II enzyme gene expression.
HO-1 in phase II enzymes had a protective effect upon cells, and it catalyzed heme to produce biliverdin, carbon monoxide, and iron. Biliverdin is transformed into bilirubin, while Nrf2 and HO-1 are powerful free radical scavengers in the body.
By regulating Nrf2-HOROS pathway, the damage degree of oxidative stress can be reduced, so as to reduce inflammation. COX-2, p38, NF-κB, and I-κB are all important factors related to inflammation. The regulation of Bcl-2 expression can control multiple signal pathways to reduce cell damage.
Activation of PPAR-γ can promote the expression of COX-2 and the production of PGE2, thus protecting the cells. Meanwhile, LPF regulated the expression of COX-2, p38 MAPK, NF-κB, and IκB-α in UVB-damaged mouse skin so that it normalized. Thus, IPF plays a role in interfering with UVB-induced skin damage.
HPLC is a common experimental method which can accurately determine the effective components of plants, and can be verified accurately in both component identification and fingerprint identification.
From HPLC assay, isomangiferin, rutin, astragalin, naringin, and quercetin are the main flavonoids present in LPF. Isomangiferin is an antioxidant flavonoid with antitussive, expectorant, cardiotonic, diuretic, and antidepressant effects.
In vivo animal studies also showed that it could repair liver damage caused by high-fat feed. These two actions synergistically inhibited the expression of COX-2 and iNOS in skin treated with UVB. It has anti-inflammatory, anti-oxidant, cardiotonic, anti-arrhythmia, analgesic, antibacterial, anti-allergic, and anti-hepatotoxic effects as well as the effects of enhancing immune resistance, stimulating the production of interferon, dilating blood vessels, and protecting the myocardium.
Naringin also lowers blood cholesterol, decreases the formation of thrombus, and increases the local microcirculation and nutrition supply, thereby indicating that it could be used to produce drugs for preventing and treating cardiovascular and cerebrovascular diseases.
Additionally, quercetin blocked the inhibition of cell membrane fluidity reduction and mitochondrial membrane depolarization, thereby blocking the inhibition of the outflow of cytochrome c , which in turn could inhibit apoptosis.
