Photo-DSC on the other hand, is a much more recent technique which has been developed thanks to technological developments in thermal analysis and coupled techniques. Until very recently, it has been used mainly to study photopolymerization or photocuring reactions by measuring the heat of reaction. We proposed the use of this powerful technique to study polymer photo-aging, using the photo-DSC as an accelerated aging device and coupled in situ analysis of the modification of the morphology of the materials. In this case, the crystallizability of the polymer is used as an indicator of the structural modifications. [Pg.259]

The UV radiation causes premature skin aging. This photo-aging is characterized by wrinkles, mottled pigmentation, dry and rough skin, and loss of skin tone. Use of topical vitamin A derivatives like tretinoin can improve photo-aged skin mainly by changing epidermal differentiation.52 However, skin dryness does not improve and even worsens with retinoid therapy, as well known from its systemic and topical use in several diseases in clinical dermatology. [Pg.123]

Impairment of the retinoid signal transduction pathways occurs as a result of prolonged UV exposure. Down regulation of nuclear receptors for Vitamin A occurs,269 resulting in a functional deficiency of Vitamin A. Application of Vitamin A derivatives would appear to be an obvious treatment modality. Topical application of Vitamin A does increase the HA in the epidermal layer, increasing the thickness of the HA meshwork after prolonged treatment.270 Vitamin A thus enhances repair, as can be demonstrated in photo-aged hairless mouse model.271 The decline in GAG, and in particular HA deposition that occurs with UVB irradiation, can be entirely prevented by retinoic acid treatment. [Pg.265]
