Published: Jan. 7, 2025

Inclusion complexation of the sunscreen ingredient avobenzone (AVB) with β-cyclodextrin (β-CD) was investigated to improve its aqueous solubility and photostability; another ultraviolet (UV) filter, oxybenzone (OXB), phytochemical antioxidant curcumin (CUR) served as a comparison. In this study, 1-octanol/water partition coefficients, acid dissociation constants, phase-solubility diagrams β-CD, ultraviolet–visible (UV–vis) spectral changes induced by UVA1 (365 nm) irradiation were evaluated. β-CD at concentrations 50–100 times that AVB most effectively protected photostability AVB. Additionally, an UVA1-insensitive species diketo tautomer, which has UVC-absorbing band potential cause photodegradation, stored in inclusion complex. Acetonitrile–water mixtures various volume ratios screened mimic internal cavity for tautomeric using nuclear magnetic resonance (NMR) integrals components.

Published: Nov. 16, 2024

Overexposure to ultraviolet radiation mainly leads skin disorders (erythema, burns, immunosuppression), aging, and cancer as the most serious side effect. It has been widely accepted that using sunscreen products is an important way protect against harmful effects of UV rays. Although commercial sunscreens have constantly changed improved over time, there are emerging concerns about safety conventional, organic, filters due adverse on humans (such photoallergic dermatitis, contact sensitivity, endocrine-disrupting effects, etc.) well accumulation in environment aquatic organisms. This why natural compounds increasingly being investigated used cosmetic pharmaceutical sunscreens. Some these available, non-toxic, safer for use, considerable protective properties less effects. Plant-based such flavonoids can absorb UVA UVB rays possess antioxidant, anticarcinogenic, anti-inflammatory contribute photoprotection. Apart from flavonoids, other certain vegetable oils, carotenoids, stilbenes, ferulic acid also UV-absorbing properties. vitamins might be beneficial protection their antioxidant activity. Therefore, aim this research was gain insight into potential replace or reduce amount conventional filters, based recent research.

Nanotechnology is revolutionizing fields of high social and economic impact. such as human health preservation, energy conversion storage, environmental decontamination, art restoration. However, the possible global-scale application nanomaterials raising increasing concerns, mostly related to toxicity materials at nanoscale. The possibility using in cosmetics, hence products aimed be applied directly body, even just externally, strongly debated. Preoccupation arises especially from consideration that are synthetic origin, often seen "artificial" their effects unpredictable. Melanin, this framework, a unique material since nature it plays important roles specific cosmetics cover, photoprotection hair skin coloration. Moreover, melanin present form nanoparticles, clearly observable ink some animals, like cuttlefish. artificial nanoparticles share same biocompatibility natural ones chemical photochemical properties. Melanin nanocosmetic agent, but its actual still under development, also because regulatory issues.

Enhancing Photoprotection and Mitigating Ex Vivo Stratum Corneum Oxidative Stress: A Multifunctional Strategy Combining Rosmarinic Acid with UVB Filters

Antioxidants, Journal Year: 2025, Volume and Issue: 14(3), P. 274 - 274

Published: Feb. 26, 2025

Exposure to ultraviolet (UV) radiation is a major contributor skin injury, including sunburn, photoaging, and augmented risk of cancer, primarily through the generation reactive oxygen species (ROS) that induce oxidative stress. Rosmarinic acid (RA), natural phenolic compound with antioxidant several other biological properties, has shown promise in mitigating such damage when incorporated into sunscreens. We evaluated RA's possible interactions potential enhance efficacy three worldwide known UVB filters-ethylhexyl methoxycinnamate (EHMC), octocrylene (OCT), ethylhexyl salicylate (EHS). The performance sunscreens without RA (0.1% w/w) was analyzed vitro vivo photoprotective assessments. HPLC-TBARS-EVSC (high-performance liquid chromatography-thiobarbituric substances-ex stratum corneum) protocol, which quantified stress reduction human corneum, also used. assays showed had distinct levels filters. When associated EHMC, exclusively acted range (SPF-enhancing effect). Remarkably, for EHS, contributed higher profile total UV spectrum. OCT-RA sample reached highest critical wavelength value parallelly OCT, boosting SPF by more than 157% comparison OCT. However, its not affected addition, being comparable EHS-RA. Furthermore, protocol highlighted ability reduce lipid peroxidation, exhibiting most notable protective effect. These findings underscore as multifunctional additive sunscreen systems, enhancing both photoprotection mitigation.

Potential of Natural-Based Sun Protection Factor (SPF): A Systematic Review of Curcumin as Sunscreen

Cosmetics, Journal Year: 2025, Volume and Issue: 12(1), P. 10 - 10

Published: Jan. 15, 2025

Exposure to ultraviolet (UV) radiation from the sun significantly damages skin, leading premature aging, hyperpigmentation, and oxidative stress that disrupts skin homeostasis. UV increases production of reactive oxygen species (ROS), accelerating deterioration. Although sunscreens remain primary method for protection, chemical-based formulations are often associated with side effects, such as allergic reactions acne. To address these concerns, inclusion natural ingredients in sunscreen has gained attention. Curcumin, an active compound found turmeric (Curcuma longa) Java xanthorrhiza), is well-known its antioxidant anti-inflammatory properties. This review explores potential curcumin a ingredient enhancing Sun Protection Factor (SPF) products. A systematic literature was conducted, analyzing 200 articles sourced Google Scholar PubMed using keywords “Curcumin”, “Curcuma”, “Antioxidant”, “Anti-Inflammatory”, “Sun Factor”. Studies unrelated protection were excluded. The findings, presented tabular form, indicate Curcuma exhibit significant enhance SPF values due their antioxidant, anti-inflammatory, UV-absorbing Additionally, may aid repair following UV-induced damage. However, specific concentration various remains unknown, further research necessary determine optimal use. Consideration additional excipients also required maximize efficacy. In conclusion, demonstrates considerable promise sustainable effective protecting radiation, offering safer alternative conventional sunscreens.
