GJ Fisher, The pathophysiology of photoaging of the skin. Early reactions include erythema and sunburn while delayed effects relate to damage on a molecular level such as changes in pigmentation and the development of precancerous lesions and tumors.12-14, The clinical image of prematurely aged skin includes wrinkles and coarse skin; over-drying; abnormal keratinocyte maturation; discolored, mottled hyperpigmentation; telangiectasia with hypertrophic solar keratosis and seborrheic keratosis; and reduced skin elasticity.15 UVA enhances the effect of UVB in the epidermis and damages the connective tissue.5, 7 Further, UVA disturbs microcirculation in the dermis and causes angiogenesis and a fragmentation of elastic fibers.16. Prior to IBR's work, carotenoids were impractical for use in skin care products because of their deep orange and red colors. Genetic changes in the activity of cells occur, such as slowed regeneration processes, weakening of natural resistance and a reduced ability to adapt and respond to environmental stress.
