By now, you’ve probably already tried everything—from high-end, local, or Korean skincare. (ALSO READ: Get your Hair, Nails, Eyebrows, and Face Done in One Place: […]

It can seem as though the beauty industry is shouting about a new, often unpronounceable and supposedly miracle active skincare ingredient every other week.

Are you struggling with a skin problem and haven’t found the right fix? Read our guide on active ingredients so the next time you are dealing with a breakout, dullness or fine lines, you will know exactly what you need to fix them. Active ingredients are designed to target specific skin concerns.

Human skin is continually changing. The condition of the skin largely depends on the individual's overall state of health. A balanced diet plays an important role in the proper functioning of the human body, including the skin. The present study draws attention to bioactive substances, i.e., vitamin …

Quercetin and kaempferol, two well-known flavonols, were chemically conjugated with glucose to produce the corresponding flavonol glucosides, and the following biological activities were evaluated for cosmeceutical development: antioxidant activity, ability to increase collagen synthesis, and moisturizing activity. Among the synthetic flavonol glucosides, quercetin-3-O-β-D-glucoside significantly enhanced collagen synthesis (60 %) compared to quercetin. Kaempferol-3,7-di-O-β-D-glucoside showed promising skin-moisturizing effects, inducing a sixfold increase in the expression of aquaporin-3. Thus, both quercetin-3-O-β-D-glucoside and kaempferol-3,7-di-O-β-D-glucoside were shown to possess interesting biological activities which warrant their further development as cosmetic ingredients.

A variety of non-filtering agents have been introduced to enhance sunscreen photoprotection. Most of those agents have only weak erythema protective properties but may be valuable and beneficial in supporting protection against other effects of UV radiation, such as photoimmunosuppression, skin aging, and carcinogenesis, as well as photodermatoses. The question arises how to measure and evaluate this efficacy since standard SPF testing is not appropriate. In this perspective, we aim to provide a position statement regarding the actual value of SPF and UVA-PF to measure photoprotection. We argue whether new or additional parameters and scales can be used to better indicate the protection conferred by these products against the detrimental effects of natural/artificial, UV/visible light beyond sunburn, including DNA damage, photoimmunosuppression and pigmentation, and the potential benefits of the addition of other ingredients beyond traditional inorganic and organic filters to existing sunscreens. Also, we debate the overall usefulness of adding novel parameters that measure photoprotection to reach two tiers of users, that is, the general public and the medical community; and how this can be communicated to convey the presence of additional beneficial effects deriving from non-filtering agents, e.g., biological extracts. Finally, we provide a perspective on new challenges stemming from environmental factors, focusing on the role of the skin microbiome and the role of air p...

Ethnopharmacological studies have become increasingly valuable in the development of botanical products and their bioactive phytochemicals as novel and effective preventive and therapeutic strategies for various diseases including skin photoaging and photodamage-related skin problems including abnormal pigmentation and inflammation. Exploring the roles of phytochemicals in mitigating ultraviolet radiation (UVR)-induced skin damage is thus of importance to offer insights into medicinal and ethnopharmacological potential for development of novel and effective photoprotective agents. UVR plays a role in the skin premature aging (or photoaging) or impaired skin integrity and function through triggering various biological responses of skin cells including apoptosis, oxidative stress, DNA damage and inflammation. In addition, melanin produced by epidermal melanocytes play a protective role against UVR-induced skin damage and therefore hyperpigmentation mediated by UV irradiation could reflect a sign of defensive response of the skin to stress. However, alteration in melanin synthesis may be implicated in skin damage, particularly in individuals with fair skin. Oxidative stress induced by UVR contributes to the process of skin aging and inflammation through the activation of related signaling pathways such as the mitogen-activated protein kinase (MAPK)/activator protein-1 (AP-1), the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt), the nuclear factor kappa B (NF-κB) a...

Background The constant exposure to solar ultraviolet radiation (UV) has a variety of harmful effects on human health. Although synthetic sunscreen products have been introduced as a preventive/therapeutic strategy, with the realization of their adverse side effects, the recent trend is to search for human friendly alternative formulations especially of plant origin. Therefore, the present study focuses on evaluation of photoprotective activity of aqueous extracts (1 mg/ml) of eleven medicinal plants in Sri Lanka that have been widely employed in traditional medicine as treatment options for various skin diseases and to improve the complexion. Methods For the determination of UV filtering potential of the extracts, UV absorption was measured and the sun protection factor (SPF) was calculated according the Mansur equation. The antioxidant activity was evaluated by DPPH and ABTS assays. Results Among the extracts, Atalantia ceylanica, Hibiscus furcatus, Leucas zeylanica, Mollugo cerviana, Olax zeylanica and Ophiorrhiza mungos have displayed SPF value ≥ 25, which are even higher than two commercial photoprotective creams used as reference compounds. L. zeylanica and O. mungos have displayed a high UV absorbance in 260–350 nm range indicating their potential of being broad spectrum sunscreens. In addition, the extract of O. mungos was found to be photostable, without any significant reduction in the SPF after exposure to direct solar radiation for 21 days. DPPH assay and the ABTS assay revealed that the extracts possess high antioxidant activity. Conclusion The results of the present study suggest that the presence of secondary metabolites with antioxidant property could be responsible for the high UV absorbance. Our findings would offer an exciting avenue for further research towards the development of herbal cosmetics.

Background: Skin aging can be caused by long-term ultraviolet (UV) exposure that usually called as photoaging. Administered antioxidant substances can delay the photoaging process. Purple mangosteen is known to have abundant antioxidant properties such as xanthones and anthocyanins. This study aims to determine the effect of purple mangosteen peel extract on the collagen fiber in male Wistar rats after UV-B exposure.Methods: An experimental study was conducted among 21 male Wistar rats at Histology Laboratorium, Udayana University from a period of March-October 2017. The samples were divided into 3 groups as follows: control, placebo, and mangosteen extract with 7 rats in each group. Collagen fiber was assessed by using a light microscope with 400 times magnification. Statistical analysis was carried out using SPSS ver. 21 software using one way ANOVA.Results: The study found that percentage of collagen area within control group was 61.94%, placebo group 72.90%, and mangosteen peel extract 73.63%. The mean between-group analyzed using one way ANOVA found that there was a statistically significant difference in mangosteen peel extract than control group (p=0.0000), but not statistically significant if compared with placebo group (p=0.640) on the collagen fiber in male Wistar rats.Conclusion: there was a statistically significant difference in mangosteen peel extract than control group on the thickness of collagen fiber in male Wistar rats after UV-B exposure.

Die Klasse der Anthocyane (wasserlösliche Pflanzenfarbstoffe) wirken durchblutungsfördernd und gefäßschützend. Sie haben UV-absorbierende Eigenschaften und wirken als gute Antioxidantien und schützen die Pflanze vor oxidativen Stress. In-vitro haben Anthocyane eine vielfach bessere Wirkung als Vitamin C. Sie sind aber weniger Bioverfügbar und so ist die smarte Auswahl der Rezeptur entscheidend für die Wirkung in-vivo. So…
