On the other hand, excessive sunlight exposure has been linked to all types of caused by the part of radiation from sunlight or sunlamps.[ can have mild to severe effects on skin; this can be avoided by using a proper cream or lotion or by gradually building up melanocytes with increasing exposure. Another detrimental effect of UV exposure is accelerated skin aging (also called which produces a difficult to treat effect.
