Aging causes the skin to undergo changes: 1  Cells divide more slowly and the inner layer of skin starts to thin. 2  The deeper layer of the skin, which provides the framework for the surface skin layers, loosens and unravels. 3  Oil-secreting glands shrink, leaving the skin without a protective layer of oil.
Money. Cuba operates a dual currency system. Visitors usually use the Cuban Convertible Peso (CUC), whereas locals use the Cuban Peso (CUP). The CUP is worth much less than the CUC; check transaction sums carefully. US Dollars arenât accepted as legal tender; youâll be charged 10% commission to exchange them.
The Currency The currency of Nicaragua is the cÃ³rdoba (C$), often called a 'peso' by locals, or a 'cord' by expats. CÃ³rdobas come in coins of C$0.25, C$0.50, C$1, C$5 and C$10 and bills of C$10, C$20, C$50, C$100, C$200 and C$500. Bills of C$100 and larger can be difficult to change; try the gas station, bank or street money changer.
