(2010) proved that -tocotrienol can suppress PGE2, COX-2, and interleukins in vitro. Naguib, Y., Hari, S. P., Passwater, R., Jr., and Huang, D. Antioxidant activities of natural vitamin E formulations. See additional information. Therefore, supplementation with vitamin E in the form of tocotrienol may efficiently protect skin from aging. Dermatol. However, the function and appearance of skin visibly degenerates with age due to its frequent exposure to harmful effects of the environment, including ultraviolet irradiation and hazardous substances, in addition to the progression of oxidative stress in aging. A: Almost all of the in-vitro, animal, human studies published so far, on the health benefits of tocotrienols was carried out with palm based tocotrienols. The overproduction of ROS as a result of UV radiation also induces downstream signaling, which activates mitogen-activated protein kinase (MAPK) and nuclear factor-B (NF-B). The https:// ensures that you are connecting to the 17 (21), 21962205. The physical features of wrinkles caused by intrinsic and extrinsic factors are different. Interestingly, only -tocotrienol, -tocotrienol, and TRF were found to significantly inhibit tyrosinase activity. Most teens and adults (including pregnant women) should get 15 mg (22.5 IU) per day of vitamin E. Since mixed tocopherols are To study the effects of these treatments on pigmentation, the melanin content and tyrosinase enzyme activity were measured. Tocotrienol-rich fraction from palm oil affects gene expression in tumors resulting from MCF-7 cell inoculation in athymic mice. Ter. The difference between tocotrienols and tocopherols is that tocotrienols have double bonds. home J Nutr 2002;132(10):3113-3118. (2010). Conversely, UVB radiation has a lower penetration rate, as it can only penetrate up to the epidermis layer. Anticancer Res. -Tocotrienol was found to prevent telomere shortening by decreasing telomerase activity at concentrations of 80M for young fibroblasts and 40M for old fibroblasts. official website and that any information you provide is encrypted People apply tocotrienols to the skin for buns, hair growth, and scars. View abstract. UV radiation exposure also provokes skin inflammation by producing inflammatory cytokines from epidermal keratinocytes and dermal fibroblasts. -Tocotrienol was found to reduce pigmentation in skin tumors induced in nude mice (Yap et al., 2010). (2003) tested the effect of a 14-day regimen on skin moisturization. Br J Nutr 2008;99(6):1247-1254. Meanwhile, Yamada et al. (2011). Ann N Y Acad Sci. (2014) observed decreased melanin content in cultures treated with TRF. Tocotrienols are often found in natural sources such as palm or rice brain oil. The regimen consisted of 5% w/vol -tocotrienol treatment followed by 10% benzoyl peroxide (BPO) treatment for 7days each. The results showed that skin hydration was improved, while the roughness of the skin and appearance of wrinkles were markedly reduced. WebAlthough tocopherols and tocotrienols are available from the diet, -tocopherol is the primary form of vitamin E found and maintained in the body, due to the specificity of a transport protein for -tocopherol (see the article on Vitamin E ). There isn't enough reliable information available about Tocotrienols to know if it is safe. Sylvester, P. W., Nachnani, A., Shah, S., and Briski, K. P.

Pregl. Curr. J. Mol. In this review, the effects of tocotrienol on skin health, including pigmentation, moisture, and wrinkles during aging and UV exposure, were systematically evaluated based on a literature search of the PubMed and Scopus databases. Sonneville-Aubrun, O., Yukuyama, M. N., and Pizzino, A. The present data showed that tocotrienols protect the skin from inflammation, UV radiation and melanin accumulation. (2009b) showed that skin moisture was improved after 56weeks of application with the self-developed whitening lotion containing tocotrienol. Diet-derived and topically applied tocotrienols accumulate in skin and protect the tissue against ultraviolet light-induced oxidative stress. The SC acts as a skin barrier due to its occlusive effects formed by the lipid bilayer matrix (Foster et al., 2020). However, conflicting evidence exists. Inflammation stimulates macrophages to eliminate damaged cells and oxidized lipids from the system. Cell Melanoma Res. vitamins, herbs, dietary supplements a-z list. Sci. J. Clin. Due to its potent antioxidant properties, tocotrienols can help to prevent and reduce the damage caused by UV irradiation by inhibiting DNA damage, lipid oxidation, telomere shortening, and the reduction in collagen content (Figure 2). doi:10.1093/gerona/glw240, Gu, Y., Han, J., Jiang, C., and Zhang, Y.

The results showed that the treated group had significantly lower skin reactions on the buttocks, except for erythema, than both the untreated and vehicle groups. In addition, epidermal proteins, such as aquaporin-3 (AQP3), also help to retain water content in the SC (Verdier-Svrain and Bont, 2007). These findings suggest that tocotrienols may provide more protection to aging skin than tocopherols and vitamin C. Thus, this review aims to summarize the effects of tocotrienols on age-related skin conditions based on evidence from in vitro and in vivo studies. 2022 Dec 24;15(1):92. doi: 10.3390/nu15010092.

Weng-Yew, W., Selvaduray, K. R., Ming, C. H., and Nesaretnam, K. Suppression of tumor growth by palm tocotrienols via the attenuation of angiogenesis. The skin is the primary protection layer that shields the body from environmental effects (Cravello and Ferri, 2008). UV exposure increases measures of pigmentation, such as melanin and erythema. PMC Tocotrienols also seem to benefit people with a genetic disorder called familial dysautonomia by increasing levels of a certain protein in blood cells. Elangovan, S., Hsieh, T. C., and Wu, J. M. Growth inhibition of human MDA-mB-231 breast cancer cells by delta-tocotrienol is associated with loss of cyclin D1/CDK4 expression and accompanying changes in the state of phosphorylation of the retinoblastoma tumor suppressor gene product. In another study by Nagakawa et al. Wrinkles develop due to extracellular matrix destruction and skin inflammation (Bae et al., 2010). A total of 103 duplicates were removed, which resulted in 118 unique articles. Tocotrienols are a subfamily of vitamin E with potent antioxidant activity. (2008). View abstract. WebIn a laymans term, tocotrienols can be defined as the Unsaturated Form of Vitamin E. Only UVA and UVB radiation can penetrate our ozone layer. Protease-activated receptor 2 induces ROS-mediated inflammation through Akt-mediated NF-B and FoxO6 modulation during skin photoaging. Ultimately, skin damage manifests through two mechanisms, namely, photoaging and photocarcinogenesis. If the repair mechanism fails to conduct its role, it will cause the inactivation of tumor-suppressor genes and elimination of negative regulatory proteins that subsequently lead to tumor development. -Tocotrienol could also reduce ROS generation, NF-B, COX-2 mRNA expression, PGE2 production, and interleukins (Makpol et al., 2010; Nakagawa et al., 2010). -, Bang E., Kim D. H., Chung H. Y. (2021). The downregulation of PGE2 is crucial to stop the inflammatory effects caused by UVB radiation, as it acts as the main modulator that activates the release of other inflammatory factors, such as interleukins. Osmolyte transporter expression is reduced in photoaged human skin: Implications for skin hydration in aging. 131 (2), 369S373S. Among these factors, oxidative stress has been widely studied as one of the main causes of skin aging. Based on in vitro studies, -tocotrienol is believed to be able to downregulate the production of melanin (Michihara et al., 2010; Ng et al., 2014). After 6weeks, half of the mice were exposed to UV irradiation once daily for 7days. The skin is the largest organ of the body that protects from mechanical, thermal, and physical injury. These factors result in phenotypic changes in the skin, including wrinkling, pigmentation, reduced elasticity, and hydration during aging. Free Radic. Redox Biol. Guthrie, N., Gapor, A., Chambers, A.

Inhibition of proliferation of estrogen receptor-negative MDA-MB-435 and -positive MCF-7 human breast cancer cells by palm oil tocotrienols and tamoxifen, alone and in combination. Some research shows that tocotrienols might decrease blood sugar in people with type 2 diabetes. Both tocotrienols and tocopherols have similar chemical structures. At this time there is not enough scientific information to determine an appropriate range of doses for tocotrienols (in children/in adults). Pharmacol. Experts believe that tocotrienols, such as annatto tocotrienols have many health benefits some that are even more powerful than those found in the more common tocopherols. Rose petal extract (rosa gallica) exerts skin whitening and anti-skin wrinkle effects. The activation of NF-B leads to a decrease in collagen production, while the level of the MMP gene increases (Zhang and Duan, 2018). Dermatol Surg 1999;25:311-5. The TRF in this study consisted of a tocotrienol and -tocopherol mixture. Atherosclerosis 2005;182(2):367-374. doi:10.1684/ejd.2020.3930, Zhuang, Y., and Lyga, J.

Compared to tocopherol isoforms, tocotrienols are assimilated into cellular membranes more easily and absorbed by skin more effectively (Makpol et al., 2010). Tocotrienols are a subfamily of vitamin E with potent antioxidant activity. (2010) performed several studies to understand the effects of tocotrienol isomers on tyrosinase activities in both human and animal samples. Careers. People take tocotrienols by mouth for aging, Alzheimer's disease, clogged arteries, cancer, diabetes, a genetic disorder called familial dysautonomia, high cholesterol, kidney failure, and stroke. View abstract. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. In HR-1 hairless mice, oral tocotrienol suppressed UVB-induced changes in skin thickness, COX-2 protein expression, and hyperplasia, while -tocopherol resulted in no changes. Many natural antioxidant compounds have been studied extensively to reverse the signs of aging skin. J. Gerontol. In theory, taking tocotrienols along with diabetes medications might cause blood sugar levels to drop too low. Vitam Horm 2007;76:419-433.
