Skin samples in RNAlater were washed with HBSS (+) and then separated into epidermis and dermis as described above. The mobile phase was water adjusted to pH 2.6 using phosphoric acid with a flow rate of 0.4 mL/min. 5. "It naturally has a bright red/orange color, and its high content in salmon is what gives it its color. These products are not intended to diagnose, treat, cure, or prevent any disease. Wholesale According to Plescia, "astaxanthin can help protect the skin and reduce the appearance of fine lines, wrinkles, hyperpigmentation in addition to helping repair DNA damage due to UV rays.". 3. No, Is the Subject Area "Dermis" applicable to this article? Yes You may be surprised to hear that this under the radar ingredient is what gives flamingos, salmon and shrimp their pink color. This rejuvenating gel from DHC essentially does it all, revitalizing and brightening skin with an all-star roster of antioxidants. Wards off wrinkles: "Astaxanthinhas been shown to neutralize free radical damage, calm inflammation in the skin in eczema, and improve the appearance of fine lines and wrinkles in aging skin," notes Zeichner. All viewers of this content, especially those taking prescription or over-the-counter medications, should consult their physicians before beginning any skincare, nutrition, supplement or lifestyle program. TGM2 identified as a stable interaction partner of collagen VII is an important enzyme for protein cross-linking. The mouse epidermis (0.5 cm2), prepared as described above, was homogenized with 100 L of saline and then added to 300 L of ethanol. Copyright: 2017 Komatsu et al. https://doi.org/10.1371/journal.pone.0171178.s001. Based on the body weight, the calculated astaxanthin intake in the condition of this study was 20200 mg per day for human. less pigmentation and more luminosity and moisture). However, rodents lack the MMP-1 gene, which appears to be functionally replaced by MMP13 [50]. In cultured human skin fibroblasts, astaxanthin prevented UVA-induced DNA damage [20]. Daily food intake and body weight gain were not significantly different among the four groups during the experimental period (Table 2). 4. The astaxanthin monoester fraction eluted with acetone/hexane (1/5) was collected and then applied to silica TLC developed in chloroform/methanol/water (64/16/2, v/v/v) for checking the purity. Astaxanthins potent antioxidant activity along with its superior stability make it an exceptional ingredient for skin care effectively assisting with prevention and correction. Despite being weakly carcinogenic as compared to UVB, UVA radiation contributes up to 95% of the total UV exposure and plays a substantial role in photoaging of the human skin [8]. Plus, it has a positive effect on your overall health. No, Is the Subject Area "Body weight" applicable to this article? Intrinsic and chronological skin aging is characterized by atrophy of the skin with loss of elasticity and slowed metabolic activity. Everything You Need To Know. Theviews and products expressed are not intended to treat, cure or prevent any disease. It was suggested that exposure to UVA contributes to photodamage in human skin, because UVA accounts for approximately 95% of personal exposure to solar radiation [8]. UVB radiation critically damages cellular macromolecules and induces the formation of reactive oxygen species. The thermal cycling conditions were 15 min at 95C for 1 cycle, followed by amplification for 43 cycles with melting for 15 s at 95C and annealing and extension for 30 s at 60C. Astaxanthin is a clinically evaluated antioxidant with serious skin benefits. The reduction of the activity of TGM2 accounts for the decrease of adhesion, the reduction of cross-linking of the extracellular matrix, and the decrease of epidermaldermal integrity [56]. Data represent the means SD (n = 5). Type of Ingredient: Carotenoid (yellow, orange, and red pigments that are produced by plants, algae, and bacteria). After evaporation of the collected chloroform phase, the residue was dissolved in an aliquot of methanol and then subjected to HPLC analysis for the quantification of astaxanthin [23]. Astaxanthin is can be used as a supplement and/or a topical skincare treatment. According to a 2018 review, astaxanthin's benefits might be more comprehensive than previous research suggests, and include "photoprotective, antioxidant, and anti-inflammatory effects.". In the dermis, the mRNA expression of matrix metalloprotease 13 (MMP13) was increased by UVA irradiation, and this increase was significantly suppressed in the 0.1% astaxanthin group (Fig 8a). We confirmed that dietary astaxanthin was also able to reach the skin. Astaxanthin is one of the most powerful antioxidants known to science, which makes it beneficial to all skin types. It has been suggested that AQP3 upregulation is involved in keratinocyte proliferation, epidermal hyperplasia, and barrier disruption in skin disorders [47]. Although UVC is filtered out by atmospheric ozone for the most part, both UVA and UVB radiation can reach the Earths surface and cause biological consequence to the skin [5, 6]. The other authors received no specific funding for this work. Taken together, our study indicates the protective effects of dietary astaxanthin against features of photoaging induced by UVA radiation, such as impaired barrier function and wrinkling in the skin. Petri and Lundebye reported that the accumulation of dietary astaxanthin in hairless skin of the tail was much higher than those in other tissues. NMFs generated by the proteolysis of filaggrin are essential for the retention of water within corneocytes, and result in their optimal hydration and swelling [38]. https://doi.org/10.1371/journal.pone.0171178.t001. It has been proposed that cholesterol is first sulfated in the lower epidermis, and then desulfated back to cholesterol in the outer epidermis [45] Disruption of this cholesterol sulfate cycle by chronic UVA irradiation might partly account for the abnormal desquamation of photoaging, and dietary astaxanthin may contribute to improving this disruption. Furthermore, unlike other antioxidants, astaxanthin exerts antioxidative effects without being pro-oxidative [14]. We found that the mRNA expression levels of lympho-epithelial Kazal-type-related inhibitor (LEKTI), steroid sulfatase (STS), and aquaporin 3 (AOP3) were significantly increased by UVA irradiation for 70 days. This does not alter our adherence to PLOS ONE policies on sharing data and materials. AQP3, which is a water/glycerol-transporting channel, is expressed in keratinocytes of the epidermis [46]. Exposure to UVB radiation is the primary cause of skin cancer in humans and animals [7]. Nutrients. } King calls it "a rich night cream with potent antioxidant properties thankstoastaxanthinand pycnogenol.". The distance from the lamps to the mice was approximately 18 cm, and fans circulated the air. Yes Astaxanthins unparalleled antioxidant powers make it a worthy addition to your beauty ritual. here. Furthermore, this powerhouse ingredient is 100% natural and non-GMO, making it a vital player in an effective skincare routine. cDNAs were synthesized using SuperScript RNase II reverse transcriptase (Invitrogen, Carlsbad, CA) with random hexamers. In the control group, deep coarse wrinkles were formed. In the present study, we confirmed that dietary astaxanthin reached not only the dermis but also the epidermis by using HPLC-PDA analysis. They were housed at 24 1C with a 12-h light:dark cycle. Ambati RR, Phang SM, Ravi S, Aswathanarayana RG. Profilaggrin, the precursor of filaggrin, undergoes proteolysis by KLK5 to form filaggrin monomers [39], and filaggrin is degraded into small peptides and then into free amino acids through a multistep processes involving caspase-14 [40, 41]. https://doi.org/10.1371/journal.pone.0171178.g006, https://doi.org/10.1371/journal.pone.0171178.g007. However, not all antioxidants are created equal and some can become inactive as time goes on. Nutrients. In fact, strong expression of AQP3 was detected in both the stratum basale and the stratum spinosum in acute and chronic atopic eczema, although epidermal AQP3 was expressed weakly and mainly found in the stratum basale in the case of normal condition [48]. Boasting organic ingredients like apple extract, grape stem cells, shea butter, olive oil, and the brand's unique Aquacell complex, this easy-on-the-skin eye cream fights the look of too many consecutive sleep-deprived nights. Ideal for those with sensitive skin: As Plescia points out, "Astaxanthin has also been studied to have anti-inflammatory properties aiding in skin redness, sensitivity, and inflammation. PLoS ONE 12(2): Thus, we measured the contents of pyroglutamic acid (PCA) and urocanic acid (UCA), which are the major NMFs in the epidermis, by HPLC analysis. e0171178. The parameters to assess skin wrinkles were total groove volume ratio, wrinkle area ratio, wrinkle volume ratio, and the number of wrinkles. As shown in Fig 5, astaxanthin was dose-dependently accumulated in the skin of mice, similar to the pattern observed in plasma. For analysis of mRNA expression, the skin specimens were stored in RNAlater (Qiagen, Valencia, CA) at -80C until use. At 70 days, TEWL in both the 0.01% and 0.1% astaxanthin-supplemented groups was significantly lower than that in the control UVA-irradiated group, but the effect was not dose dependent. Clay Masks: 8 Amazing Skin Benefits & How To Use, What is Bakuchiol? To our knowledge, this is one of the first in vivo studies evaluating the protective effect of dietary astaxanthin against skin photoaging induced by UVA radiation. Astaxanthin: sources, extraction, stability, biological activities and its commercial applications--a review. The effects of astaxanthin on gene expression related to barrier function in the epidermis were analyzed by using real-time RT-PCR. The mRNA expression pattern of pro-opiomelanocortin (POMC) was similar to that of MMP13, but the effect of astaxanthin was not significant (Fig 8b). It also is found in some forms of red algae. Save 15% off fresh skincare callback: cb Tominaga K, Hongo N, Karato M, Yamashita E. Cosmetic benefits of astaxanthin on humans subjects.

Astaxanthin is a naturally-occurring carotenoid, a red pigment that the microalgae produce as defense mechanism against harsh environmental conditions. Our data supports the hypothesis that the accumulation of dietary astaxanthin in the skin could be sufficient to play a preventive role against UV damage. https://doi.org/10.1371/journal.pone.0171178, Editor: Andrzej T. Slominski, University of Alabama at Birmingham, UNITED STATES, Received: December 14, 2016; Accepted: January 17, 2017; Published: February 7, 2017. Most xanthophylls from dietary sources, including astaxanthin, are present in an esterified form. Astaxanthin possesses many highly potent pharmacological effects, including anti-tumor, anti-cancer, anti-diabetic, anti-atherosclerotic, and anti-inflammatory activities [1517]. The weight of mesenteric adipose tissue in 0.01%Ax group was significantly lower than that in control group. here. ), "Astaxanthin is a potent antioxidant known as a carotenoid, found in various foods," says Joshua Zeichner, MD, a dermatologist based in New York City and the director of Cosmetic and Clinical Research in Dermatology at Mount Sinai Hospital. Giving Back Erin Jahns is a hair, makeup, and nails expert and beauty editor with over five years of experience in the industry. Our results are consistent with a previous report that UVA irradiation increased POMC expression in human keratinocytes [51] and decreased TGM2 expression in human skin fibroblasts [52]. The thickness of the epidermis is generally used as a parameter to reflect photoaging in skin. Antioxidants help to counteract the damaging effects of oxidative stress to the skin. Clinical studies showed that astaxanthin supplementation along with applying a skincare product with astaxanthin improved skin appearance, including skin tone, fine lines and wrinkles and skin smoothness. LEKTI is a potent inhibitor of not only KLK5, KLK7, and KLK14 but also caspase-14 [43]. My Account The plasma concentration of astaxanthin in the 0.1% astaxanthin group was significantly higher than that in the 0.01% astaxanthin group. that natural skin glow). UVA exposure significantly decreased the content of PCA in the epidermis, and the content in the 0.01% and 0.1% astaxanthin groups demonstrated a trend toward improvement (Fig 7a). The other authors state no conflict of interest. Join Our Newsletter Astaxanthin is a super antioxidant because it never becomes a pro-oxidant (meaning it is very stable unlike vitamin C) and penetrate both the water and fat soluble part of the cell. The funder had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. As Zeichner noted, according to research, astaxanthin contains significantly more antioxidants than other superfood heroes, is anywhere from 10 to 100 times more powerful than other carotenoids like beta-carotene and lycopene, and may even be significantly more potent than skin-enhancing vitamin C and vitamin E.

"Using wildcrafted active botanicals, this formula works to bring vitality to the look of the skin," says Plescia. In normal epidermis, cholesterol sulfate is generated by cholesterol sulfotransferase, but desulfated in the outer epidermis by STS, forming a cholesterol sulfate cycle that potently regulates epidermal differentiation, barrier function, and desquamation [44]. Product Tips & Tricks No, Is the Subject Area "Ultraviolet A" applicable to this article? The increased expression and altered cellular distribution of AQP3 found in eczema may contribute to water loss. We found that the mRNA expression of lympho-epithelial Kazal-type-related inhibitor, steroid sulfatase, and aquaporin 3 in the epidermis was significantly increased by UVA irradiation for 70 days, and dietary astaxanthin significantly suppressed these increases in mRNA expression to be comparable to control levels. In this study, we evaluated the effect of dietary astaxanthin derived from Haematococcus pluvialis on skin photoaging in UVA-irradiated hairless mice by assessing various parameters of photoaging. Clinical studies showed that Astaxanthin helped to protect against environmental stressors.

Quantitatively different from intrinsic aging, skin photoaging, which is clinically characterized by dryness, pigmentation, laxity, and deep wrinkling, occurs as a result of the accumulation of environmental damage, particularly exposure to ultraviolet radiation [3, 4]. Disclaimer: This content is for informational and educational purposes only. Press, Contact Us On the other hand, dietary astaxanthin tended to suppress the decrease of transglutaminase 2 (TGM2) mRNA expression by UVA irradiation (Fig 8c). Data are presented as the mean SD. Protects against UV rays: It's worth mentioning astaxanthin's natural knack for protecting our skin against damaging UV rays when ingested or used topically. Result times vary from as little as two weeks, up to eight. Who doesn't love a good multitasker? Astaxanthin, 3,3-dihydroxy--carotene-4,4-dione, is a carotenoid found mainly in seafood such as salmon, trout, lobster, shrimp, and fish eggs [10, 11]. Astaxanthin is one of natures most powerful antioxidants. Citation: Komatsu T, Sasaki S, Manabe Y, Hirata T, Sugawara T (2017) Preventive effect of dietary astaxanthin on UVA-induced skin photoaging in hairless mice. Astaxanthin, a carotenoid found mainly in seafood, has potential clinical applications due to its antioxidant activity. In the dermis, the mRNA expression of matrix metalloprotease 13 was increased by UVA irradiation and significantly suppressed by dietary astaxanthin. Undoubtedly, eating a healthy diet full of antioxidant-rich foods on a daily basis is the most effective way to keep oxidative stress at bay. { We love it when we discover a little-known product that turns out to be a cult-loved nugget of gold. Total RNA was extracted from the epidermis and dermis using Sepasol reagent (Nacalai Tesque) according to the manufacturers instructions and treated with DNase (Wako Pure Chemical Industries). Clinical studies demonstrated visible improvements in skin elasticity and moisture content. Fig 4 shows the dorsal skin sections stained with H&E. Mice in experimental groups were fed a diet of AIN-93G with 0.01% or 0.1% astaxanthin monoester purified from H. pluvialis (0.01%Ax and 0.1%Ax groups) (Table 1). Mice in normal and control groups were fed AIN-93G alone. Because of the exceptional purity of Icelandic water, Icelandic Astaxanthin is the purest man-made source in the world. Astaxanthin: a review of the material. Water quality plays a major role in determining heavy metal content and as well as other contaminants. Dietary astaxanthin significantly suppressed these increases in mRNA expression to control levels (Fig 6). it features both astaxanthin and Pycnogenol meant to neutralize potentially damaging free radicals while reducing inflammation and improving circulation (i.e. No irradiation was performed in the normal group. No, Is the Subject Area "Ultraviolet radiation" applicable to this article? At the end of the 70 days, the mice were sacrificed under isoflurane anesthesia. "Thus, astaxanthin can help protect the skin and reduce the appearance of fine lines, wrinkles, hyperpigmentation in addition to helping repair DNA damage due to UV rays.". Just in case the name on its own doesn't sound intense enough, we also learned that this skin-firming serum contains, wait for it, dragon's blood. PCA and UCA were detected at 210 and 270 nm, respectively, and quantified at their peak area by using a standard curve with authentic standards. https://doi.org/10.1371/journal.pone.0171178.t002, https://doi.org/10.1371/journal.pone.0171178.t003. Data represent the means SD (n = 5). Mice in the experimental groups were exposed to a dose of 20 J/cm2 five times weekly for 70 days [24]. An increase of free-radicals in the body is caused by factors in everyday life such as pollution, UV exposure, diet and unhealthy lifestyle choices, all of which lead to oxidative stress. Our results underscore the potential for astaxanthin to be further developed as a nutraceutical against photoaging. The preventive effect of dietary astaxanthin on wrinkle formation could be due to the suppression of MMP induction by UVA irradiation. The UV source was a bank of two UV lamps BLB (15 W, maximum emission intensity at 365 nm, UVP, California, USA). Total lipids were extracted from each epidermis and dermis sample, as well as from plasma samples, by using chloroform and methanol [27]. Affiliation when you join our newsletter! Moisturizes: Some studies point out that combining a topical dosage with an oral dosage (we recommend this oral supplement from the geniuses at Care/of) might help youth-preserving efforts in the long run (e.g. By contrast, the balance between the activity of proteases such as KLK7 and protease inhibitors such as LEKTI determine the rate of desquamation (corneocyte shedding) [28]. Image Sources: Red & White Smoke via Karolina Grabowska, Our Story Is the Subject Area "Diet" applicable to this article? UVA is able to penetrate the dermis, resulting in damage to dermal collagen and elastin, while UVB mainly affects the epidermis and causes DNA damage [9].
