Relationship between skin response to ultraviolet exposure and skin color type.
Sun exposure is responsible for detrimental damage ranging from sunburn to photoaging and skin cancer. This damage is likely to be influenced by constitutive pigmentation. The relationship betweenExpand

Variations in skin colour and the biological consequences of ultraviolet radiation exposure
Harmful consequences of sun exposure range from sunburn, photoageing and pigmentary disorders to skin cancer. The incidence and extent of these detrimental effects are largely due to the degree ofExpand

Direct role of human dermal fibroblasts and indirect participation of epidermal keratinocytes in MMP-1 production after UV-B irradiation
Abstract. In vivo, matrix metalloproteinases are produced in response to ultraviolet B (UV-B) irradiation and are considered to be involved in connective tissue alterations observed in photoaging.Expand

Galectin-7, a human 14-kDa S-lectin, specifically expressed in keratinocytes and sensitive to retinoic acid.
A cDNA encoding a novel member of the S-lectin family has been cloned from human epidermis. The 14-kDa protein of pI7 predicted by the 136-amino-acid open reading frame of the sequence was calledExpand

Evaluation of the Protective Effect of Sunscreens on In Vitro Reconstructed Human Skin Exposed to UVB or UVA Irradiation
Abstract We have previously shown that skin reconstructed in vitro is a useful model to study the effects of UVB and UVA exposure. Wavelength-specific biological damage has been identified such asExpand

Different Oxidative Stress Response in Keratinocytes and Fibroblasts of Reconstructed Skin Exposed to Non Extreme Daily-Ultraviolet Radiation
Experiments characterizing the biological effects of sun exposure have usually involved solar simulators. However, they addressed the worst case scenario i.e. zenithal sun, rarely found in commonExpand

Ultraviolet B induces hyperproliferation and modification of epidermal differentiation in normal human skin grafted on to nude mice
Background  For ethical and technical reasons, the in vivo biological effects of ultraviolet (UV) radiation on skin are difficult to study in human volunteers. The use of human skin grafted on toExpand

UVA exposure of human skin reconstructed in vitro induces apoptosis of dermal fibroblasts: subsequent connective tissue repair and implications in photoaging
The skin reconstructed in vitro has been previously shown to be a useful model to investigate the effects of UVB exposure (). The present study describes the response to UVA irradiation. MajorExpand

Exposure to Non-Extreme Solar UV Daylight: Spectral Characterization, Effects on Skin and Photoprotection
The link between chronic sun exposure of human skin and harmful clinical consequences such as photo-aging and skin cancers is now indisputable. These effects are mostly due to ultraviolet (UV) raysExpand

Melanocytes Sense Blue Light and Regulate Pigmentation through Opsin-3.
The shorter wavelengths of the visible light spectrum have been recently reported to induce a long-lasting hyperpigmentation but only in melano-competent individuals. Here, we provide evidenceExpand
