Immunologic Protection Afforded by Sunscreens In Vitro [PDF]

, 1997
Several studies have suggested a lack of correlation between sunscreen sun protection factor and protection of the skin immune system, potentially allowing greater damage to the skin by removing the natural protective erythemal response to sun exposure ...

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.

The photophysics and photochemistry of aromatic 1,3-dicarbonyl compounds used as UVA sunscreens [PDF]

, 1999
UV radiation can cause harmful effects to human skin, including premature skin ageing and skin cancer. Historically, sunscreens were developed to filter out UVB (290 nm-320 nm), but now the importance of UVA (320 nm-400 nm) sunscreens is realised.

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.

Benefits of Anti-Aging Actives in Sunscreens [PDF]

, 2017
Sunscreens are functional, utilitarian, cosmetic products. The criteria of purchase are different from those for skin care and make-up. Companies are trying to add glamour and value to basic sunscreens by incorporating “active” ingredients (other than UV

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

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 ...

Phenolic composition and multi‐target bioactivities of Globularia alypum extracts across seasons

JSFA reports, EarlyView.
Abstract Background This study investigates the influence of seasonal variation on the phytochemical profile and biofunctional activities of ethanolic leaf extracts from Globularia alypum. Leaves collected across four seasons were extracted with a hydroethanolic solvent (80:20, v/v) and analyzed by LC‐ESI‐MS/MS.

Managing Skin Diseases During Pregnancy: Treatment Discontinuation, Concerns and Physician Counselling

JEADV Clinical Practice, EarlyView.
Physiological changes during pregnancy can trigger or worsen dermatological conditions, yet evidence‐based guidance for safe management remains limited. In a cross‐sectional survey of 273 pregnant women, 33.7% reported having a skin disease, and 56% experienced worsening of symptoms.
