Based on our previous finding (Biochem. Biophys. Res. Commun., 223, 578-582, 1996) of singlet oxygen generation from coproporphyrin excreted on the skin surface from Propionibacterium acnes, we hypothesized that singlet oxygen formed in this way under UV exposure would promote peroxidation of skin surface lipids. We found that squalene was oxidized efficiently by singlet oxygen derived from coproporphyrin under UV exposure, and that the rate constant of squalene peroxidation by singlet oxygen… Expand
Squalene and Skin Barrier Function: From Molecular Target to Biomarker of Environmental Exposure
The human skin naturally faces an aerial oxidative environment . The environment presents however a variable oxidative potential since enhanced by solar rays (UV, Visible) possibly combined toExpand
Oxidization of squalene, a human skin lipid: a new and reliable marker of environmental pollution studies
TLDR
In vitro, ex vivo and in vivo testings are proposed, aiming at studying ingredients or products capable of boosting or counteracting such chemical changes that, globally, bring adverse effects to various cutaneous compartments. Expand
Photo-Oxidation Products of Skin Surface Squalene Mediate Metabolic and Inflammatory Responses to Solar UV in Human Keratinocytes
TLDR
It is indicated that Sq could be a primary sensor of solar UV irradiation in human SSL, and products of its photo-oxidation mediate/induce metabolic and inflammatory responses of keratinocytes to UVA+UVB, which could be relevant for skin inflammation in the sun-exposed oily skin. Expand
Sebum, inflammasomes and the skin: current concepts and future perspective
TLDR
The potential role of inflammasomes (innate immune complexes) in the inflammatory response associated with UVR‐induced lipid peroxidation is examined, as well as the incorporation of new molecules into current skin therapies which better target oxidised lipids and or downstream mediators/pathways. Expand
Surface Lipids as Multifunctional Mediators of Skin Responses to Environmental Stimuli
TLDR
Qualitative modifications of SSL represent a pathogenetic sign of diagnostic value in dermatological disorders involving altered sebum production, like pytiriasis versicolor, acne, atopic or seborrheic dermatitis, as well as photo-aging. Expand

TLDR
Lipid oxidation products produced by these mechanisms are observed in human skin and induce various skin diseases, but in contrast to plasma and other tissues, identification and quantitative measurement of lipid oxidation products in skin are scarce and should be the subjects of future studies.

Niacinamide and 12‐hydroxystearic acid prevented benzo(a)pyrene and squalene peroxides induced hyperpigmentation in skin equivalent
TLDR
Topical stressor‐induced hyperpigmentation was achieved in vitro, with known bioactives showing protective benefits, and niacinamide was particularly effective against benzo(a)pyrene damage. Expand
Effects of Dietary Paprika Xanthophylls on Ultraviolet Light-Induced Skin Damage: A Double-Blind Placebo-Controlled Study.
TLDR
The results indicate the efficacy of dietary paprika xanthophylls in suppression of UV-induced skin damage and there were no significant differences in facial skin parameters between the verum and placebo groups. Expand
Evaluation of squalene oxidation mechanisms in human skin surface lipids and shark liver oil supplements
TLDR
The first evidence suggesting that the analysis of SQOOH isomers enables estimation of oxidation mechanisms is presented, which may provide a foundation for the prevention of skin diseases and food deterioration via regulation of squalene oxidation. Expand
Oxidation of squalene by singlet oxygen and free radicals results in different compositions of squalene monohydroperoxide isomers
TLDR
Results suggest that the analysis of SQOOH at the isomeric level allows for the determination of the cause of SQ oxidation in various samples, and provides a foothold for future studies concerning the prevention of SQ oxide. Expand

Mechanism of skin surface lipid peroxidation.
TLDR
Results may show that squalene peroxidation was mediated by singlet oxygen and the inhibitory effect of epidermal protein on the deposition or the formation of lipid peroxide in skin surface was suggested. Expand
Skin photosensitizing agents and the role of reactive oxygen species in photoaging.
TLDR
The skin-damaging effects of UVA appear to result from type II, oxygen-mediated photodynamic reactions in which UVA or near-UV radiation in the presence of certain photosensitizing chromophores leads to the formation of reactive oxygen species. Expand

A clear signal of singlet oxygen luminescence was detected in phosphatidylcholine suspensions irradiated by UVA, which affects the balance of UV radiation on the immune system, which is comparable to effects of broadband UVA irradiation. Expand
