Citrus bioflavonoids and skin glow -
In another study, grape seed extract also decreased the level of ROS in UVB-irradiated human keratinocytes in vitro. Further, NF-kB p65 protein levels, a marker of inflammatory signaling, increased in untreated cells following UVB exposure.
But NF-kBp65 remained at pre-UVB exposure levels in cells cultured with grape seed extract [50]. DNA repair was significantly increased in xeroderma pigmentosum complementation group A XPA -proficient human fibroblasts that were cultured with grape seed proanthocyanidins GSPs for 3 hours while simultaneously being exposed to UVB light.
GSPs further enhanced nuclear translocation of the XPA protein and increased its interactions with ERCC1, a DNA excision repair protein [51]. These in vitro experiments demonstrate that GSP is not only capable of curbing the initiation stage of photodamage, by inhibiting ROS formation and inflammation, but may also amplify DNA repair mechanisms in skin cells.
Feeding of GSPs inhibited of UV-induced cyclooxygenase-2 COX-2 expression, prostaglandin synthesis, leukocyte infiltration and myeloperoxidase induction in the skin of SKH-1 hairless mice.
Pro-inflammatory cytokines TNF- α , interleukin 1 β and IL-6 were also lower in the skin of GSP fed mice than in control mice [52]. Chronic inflammation involves elevated production of proteolytic enzymes which then degrade the extracellular matrix of the dermis [53].
As such, the anti-inflammatory action of GSPs will reduce the UV-induced degradation in skin quality that occurs with sun exposure. Orally administered grape seed polyphenols decreased macrophage infiltration into and elastin degradation of aorta tissue as well as reduced expression of MMP-2 and MMP-9 [54].
The overall effect was to prevent excessive dilation of the aorta following repeated exposure to elastase. While this experiment did not directly involve UV irradiation of the skin, similar pathological processes were involved. And these results provide additional evidence of the ability of phytochemicals in grape seed extract to protect the structure and function of the extracellular matrix.
The addition of GSP to the diet of SKH-1 hairless mice for two weeks reduced tumor incidence, multiplicity and size after 30 weeks of UVB exposure to the skin. Biochemical analysis revealed significant reduction in lipid peroxidation, thus suggesting that the antioxidant activity of GSP is a major photoprotective mechanism [55].
Further, GSP ingestion maintained glutathione peroxidase, catalase, and glutathione levels while reducing hydrogen peroxide, lipid peroxidation, protein oxidation, and nitric oxide concentrations in the skin of UVB exposed mice. GSP also inhibited mitogen activated protein kinases MAK and nuclear factor- κβ NF- κβ signaling [56].
Additional research investigated the ability of GSP to prevent UVB-induced immunosuppression as another mechanism of protection against the development of skin cancer. In these studies, dietary GSPs mitigated UVB-induced suppression of dermal immune responses and increased IL production.
Intraperitoneal injection of a neutralizing anti-IL antibody abolished the immune protective impact of GSP [57]. From these results, it appears that antioxidant, anti-inflammation and immunomodulating activities all have some role in the photoprotective potential of grape seed extract in SKH-1 hairless mice.
Another line of anti-photoaging evidence involves melanogenesis. Feeding of grape seed extract to guinea pigs for 8 weeks resulted in less UV-induced skin pigmentation than that which occurred in control animals.
This anti-melanogenic effect appears to involve antioxidant action as there was a decrease in ROS-related proliferation of melanocytes.
Japanese melasma hypomelanosis patients ingested proanthocyanidin-rich grape seed extract for 11 months, divided into two phases with a one-month break in treatment after the first 6 months. Sun exposure is a major factor in melasma.
UV light is the primary causative agent that combines with other underlying factors to produce large areas of hyperpigmentation on the face. Since melasma is an excessive response to UV light exposure, ROS-mediated symptoms are reduced by dietary grape seed extract due to increased antioxidant capacity of the skin.
A 5-day clinical trial revealed that daily ingestion of grape seed extract increases serum total antioxidant activity.
No such increase was observed in the placebo group [61]. Again, photo damage is initiated by the production of ROS generation. Subsequent propagation of oxidative damage is attenuated by antioxidant action, and increased antioxidant activity in the serum directly translates to improved skin quality [62].
A few other clinical trials have been completed in which participants ingested dietary supplements containing grape seed extract as low as In these studies, ingestion of supplements containing grape seed extract significantly increased collagen and elastic fiber density both on the face and arm as well as skin luminosity by Significant improvements in erythema, skin hydration, skin radiance, overall appearance including fine lines and wrinkles and dermal ultrasound density were also evident.
Mottled pigmentation of the skin was also significantly reduced [63] [64] [65] [66]. Citrus species are some of the most widely cultivated fruits in the world.
Citrus fruit, juices, and processed compounds are major sources of nutrients in the human diet. Citrus is a well-known source of bioactive compounds, with flavonoids being major components [67]. Flavonoids are a large group of polyphenolic secondary metabolites widely occurring in plants.
Flavonoids exhibit a wide range of biological activities. Hesperidin is reported to be the major flavonoid in orange and lemon [68] [71]. The bioflavonoids naringin, isonaringin and didymin are also found in different parts of various citrus fruits [72] [73]. Naringin and isonaringin were found to be the main flavonoid in fresh, oven-dried, and freeze-dried peels of grapefruit, an important cultivar of the Citrus genus [72].
A wide range of biological and pharmacological activities have been reported for hesperidin [68] [74]. Citrus fruits and their flavonoids have potent anti-aging and photoprotective effects on the skin and could serve as powerful bioactive skincare agents [75].
The effects of hesperidin on UVA-induced skin oxidative stress and inflammation, as well as the underlying mechanisms of action, were evaluated in human keratinocytes [76]. The results of this study indicated that hesperidin directly protects cells from UVA-induced cell damage.
These data indicate that hesperidin protects keratinocytes from both UVA- and UVB-induced damage and may involve anti-oxidative and anti-inflammatory activities. Consequently, the authors of this study suggested that hesperidin might be a useful sunscreen agent. Hesperidin was also investigated for its ability to prevent apoptosis due to UVB-generated oxidative cellular stress.
Furthermore, hesperidin scavenged the 2,2-Diphenylpicrylhydrazyl DPPH radical in a dose-dependent manner [77]. In summary, the results indicate that hesperidin may scavenge ROS, absorb UVB irradiation and regulate apoptotic proteins, thus protecting human keratinocytes against UV damage.
Additionally, we observed in our laboratory that a preparation of hesperidin-rich Citrus aurantium extract, combined with vitamin C and grape seed extract Vináli , quite rapidly and thoroughly scavenged the DPPH radical. The immune-modulatory activity of hesperidin was observed in multiple studies.
The same dose of hesperidin was also found to increase the development of immunological memory in the cellular immune response. Treatment of UVA-irradiated human fibroblasts with 0.
Naringenin and naringin, well-known antioxidants, have been shown to extend the life span and health of the Caenorhabditis elegans under normal conditions as well as during UVA-induced stress.
This may be due to regulation of two stress-responsive genes skn-1 and sir Further, a synergistic anti-aging effect was observed when a combination of these compounds, in equal ratios by weight, were tested.
Jung et al. studied on the effect of naringenin on UVB-induced matrix MMP-1 expression and its direct target [82]. Like all-trans retinoic acid, a US FDA approved anti-wrinkle drug, naringenin was found to significantly inhibit UVB-induced MMP-1 expression.
This effect was further confirmed by an immunofluorescence experiment within the study. Naringin decreases oxidative UVB radiation damage in NIH-3T3 cells and the associated inflammatory response by modulating PPAR- γ expression.
As such, it can effectively prevent UVB-mediated DNA damage, photoaging, and apoptosis [83]. In another in vitro assay, fresh and oven-dried grapefruit peel extracts displayed strong cytoprotective properties in SH-SY5Y neuroblastoma cell cultures at concentrations ranging from 0.
Didymin from citrus fruit was reported to reduce the effects of UV stress on nematodes C. elegans by decreasing ROS levels and increasing superoxide dismutase SOD activity [84].
ROS levels are correlated with age-related phenotype. UV-induced bodily damage causes an increase in ROS levels. But didymin, at 0.
Kim et al. The results of this study indicate that HMF inhibits collagenase activity, increases type I procollagen content in UV-induced HDFn cells and suppresses MMP-1 expression. In addition, HMF was found to affect the MAPK signaling pathway.
These results suggest that HMF may possess photoprotective properties. Lee et al. investigated the anti-photoaging potential of hesperidin on dorsal skin in hairless mice [85].
Every day, six-week-old hairless male mice were administered 0. These animals were then exposed to UV light, and changes in skin wrinkle length and depth were measured. In the hesperidin-treated group, the average length and depth of wrinkles were significantly less than in the control group.
Further, hesperidin may reduce expression of MMP-9 and pro-inflammatory cytokines. Hesperidin was reported to decrease tryptophan intensity and interact with collagenase. It may inhibit metalloproteinases collagenase, elastases, and hyaluronidases by chelating their metal ions.
Further, a face cream containing hesperidin nanoparticles - nm may reduce black circles in the under eye region. Additionally, daily topical application of a hesperidin nanoemulsion led to a significant skin whitening, reduction in trans-epidermal water loss, and inhibition of skin irritation after exposure to UV rays [86].
Immature Citrus unshiu powder ICP contains high concentrations of flavonoids such as hesperidin and narirutin. Ingestion of ICP increased epidermal cell growth, suppressed epidermal cell mortality and prevented basement membrane destruction in the skin of UVB irradiated hairless mice [87].
ICP also improved skin hydration and decreased transepidermal water loss. An SKH-1 hairless mouse model was also employed to study the anti-photoaging of naringenin in vivo [82]. In this model, the dorsal skin was exposed to UVB three times a week with the irradiation dose being increased weekly from 1 MED to 4 MED.
The 4 MED UV dose was maintained until 15 weeks, after which skin surface impression were obtained and analyzed. During this study, the naringenin-treated group experienced significantly less MMP expression.
This inhibitory effect occurred mainly through the blockage of ERK2 kinase activity. Martinez et al. applied a topical naringenin containing formulation to hairless mice to examine its potential for reducing UVB irradiation-induced skin inflammation and oxidative damage [88].
The topical application of the naringenin formulation protected mouse skin by inhibiting edema and cytokine production TNF- α , IL-1 β , IL-6, and IL In an experiment performed by Tirkey et al. Hesperidin fed to mice also reduced superoxide generation in electron transfer and concerted proton transfer reactions [90].
A recent review of computational and experimental studies revealed that hesperidin, together with other flavonoids such as naringin, may outperform other drugs in COVID prophylaxis and treatment clinical trials [91]. Hesperidin appears to have high binding affinity for the main cellular receptors of SARS-CoV-2 and possibly dampens excessive proinflammatory responses by the immune system.
Hesperidin strongly inhibited rotavirus infectivity. A combination of citrus bioflavonoids and rosemary extract was evaluated for its photoprotective potential using human HaCaT keratinocytes as well as human volunteers.
The combination of these two ingredients increased survival rates of HaCaT cells, following UVB irradiation, more than the individual extracts alone, suggesting potential synergic effects.
The combination also decreased UVB-induced intracellular ROS and prevented DNA damage. It also decreased ex-vivo chromosomal aberrations in X-irradiated human lymphocytes isolated from the volunteers who had ingested it.
The authors of this study suggested that ingestion of the combined extracts may be an alternative treatment to topical sunscreen application [92]. Exposure to UV light leads to skin inflammation.
A systematic review and meta-analysis of randomized controlled clinical trials RCTs was conducted by Lorzadeh et al.
to evaluate the effect of hesperidin supplementation on inflammatory markers [93]. The authors used a random-effects model to examine the differences in inflammatory markers between hesperidin supplementation and a control group.
With participants included in the study, the analysis showed that hesperidin supplementation significantly decreased vascular cell adhesion molecule 1 VCAM-1 levels. As VCAM-1 is a key cell adhesion molecule involved in inflammation, the results confirm the clinical anti-inflammatory properties of hesperidin supplementation.
A placebo-controlled, randomized and double-blinded clinical trial was performed to evaluate the impact of hesperidin supplementation on the cognitive function of 37 senior healthy adults 60 - 81 years of age [94]. In this trial, participants were assigned to drink of one of two dietary interventions twice per day.
The study also found that the chronic consumption of hesperidin-rich juice significantly decreases diastolic blood pressure. This suggests that hesperidin-rich dietary interventions can prevent cognitive decline in neurodegenerative patients by increasing cerebral blood flow.
Dietary antioxidants have the potential to provide protection against skin photoaging. Results of in vitro , in vivo and human studies involving vitamin C, grape seed extract, and citrus bioflavonoids support the concept that antioxidant supplementation quenches UV-induced ROS generation in the skin.
Further, these substances also reduce inflammation and expression of proteolytic enzyme which are involved in the premature aging of the skin. Each of these well-known antioxidants exhibits multiple other health benefits to the human body. Therefore, there is ample reason to recommend regular ingestion of these natural antioxidants as a means of maintaining skin health.
