A perspective on the ultrafast photochemistry of solution-phase sunscreen molecules [PDF]

, 2016
Sunscreens are one of the most common ways of providing on-demand additional photoprotection to the skin. Ultrafast transient absorption spectroscopy has recently proven to be an invaluable tool in understanding how the components of commercial sunscreen

Recent Perspectives on Phytochemical Profile, Pharmacological Activities, and Industrial Applications of Guava (Psidium guajava)

Food Safety and Health, EarlyView.
Psidium guajava leaves contain potent bioactive compounds like quercetin, myricetin, and triterpenoids that show antioxidant, antidiabetic, anti‐inflammatory, and anticancer effects. They act by modulating NF‐κB, PPARγ, and α‐glucosidase and by inducing apoptosis and cell cycle arrest.

Cutaneous Malignant Melanoma Incidences Analyzed Worldwide by Sex, Age, and Skin Type over Personal Ultraviolet-B Dose Shows No Role for Sunburn but Implies One for Vitamin D\u3csub\u3e3\u3c/sub\u3e [PDF]

, 2016
Because the incidence of cutaneous malignant melanoma (CMM) was reported to increase with increasing terrestrial UVR (290–400 nm) doses in the US back in 1975 and a recent publication showed no association exists with UVR exposure at all, we set out to ...

Exploring the Chemical Complexity and Toxicological Behaviour of Semi‐permanent Make‐Up Pigments: A Systematic Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Semi‐permanent make‐up (SPMU), or micropigmentation, involves implanting pigments into the dermal layer of the skin for cosmetic enhancement. Unlike topical cosmetics, which are rapidly cleared from the body, SPMU pigments persist in living tissues, raising unique toxicological considerations.

Organic Sunscreens—Is Their Placenta Permeability the Only Issue Associated with Exposure During Pregnancy? In Silico Studies of Sunscreens’ Placenta Permeability and Interactions with Selected Placental Enzymes

Molecules
One of the functions of placenta is to protect the fetus against harmful xenobiotics. Protective mechanisms of placenta are based on enzymes, e.g., antioxidant enzymes from the glutathione S-transferases group (GST) or human N-acetyltransferase 2 (NAT2).

Photochemical Degradation of the UV Filter Octyl Methoxy Cinnamate Probed via Laser-Interfaced Mass Spectrometry

Molecules, 2022
Octyl methoxycinnamate (OMC) is a common UVA and UVB filter molecule that is widely used in commercial sunscreens. Here, we used gas-phase laser photodissociation spectroscopy to characterise the intrinsic photostability and photodegradation products of ...

Starfished in the sand : developing the theory of planned behaviour to predict intentions to use sunscreen on the beach : a research project presented in partial fulfilment of the requirements for the degree of Master of Arts in Psychology at Massey University, Albany, Auckland, New Zealand [PDF]

, 2003
This study examined the predictive power of the theory of planned behaviour in explaining sunscreen use intentions among beach-goers in New Zealand (n = 148) and the United Kingdom (n = 280). Generally, the theory of planned behaviour performed well with

Probing the ultrafast energy dissipation mechanism of the sunscreen oxybenzone after UVA irradiation [PDF]

, 2015
Oxybenzone is a common constituent of many commercially available sunscreens providing photoprotection from ultraviolet light incident on the skin. Femtosecond transient electronic and vibrational absorption spectroscopies have been used to investigate ...

Nanostructured lipid carriers and natural deep eutectic solvents: a highly advantageous combination for the encapsulation of curcumin

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Curcumin is a naturally derived polyphenol known for its potent biological properties. Its therapeutic potential, however, is hindered by low bioavailability. Nanostructured lipid carriers (NLCs) have emerged as advanced delivery systems to overcome such limitations. Natural deep eutectic solvents (NADESs) have garnered attention as

The Effect of Sunscreens on the Skin Barrier

Life, 2022
Transepidermal water-loss (TEWL), stratum-corneum hydration (SCH), erythema, elasticity, pH and melanin, are parameters of the epidermal barrier function and skin homeostasis that objectively indicate the integrity of the skin barrier.
