Introduction: Sun exposure has a pathogenic effect on the skin in the form of photo aging, melasma, tanning and others. Aim: The aim of this study was to evaluate the awareness of Indian population regarding effects of sun exposure, as well as to study their sun-protective attitudes and practices. Materials&Methods: A cross-sectional population-based survey using specially devised questionnaire on a stratified random sample of general population in Navi Mumbai, Maharashtra was done between January and February 2012. Results: 500 persons participated in the study, out of which 255 were females and 245 were males. Their average age was 33.5 yrs. Out of 500, 224 (44.8%) subjects were aware of the damage caused by sun exposure. Also, 82.2% subjects were aware about sunscreens. Despite that, only 69 (13.8%) participants used sunscreens. Commonest factor for non-usage of sunscreens was its cost-ineffectiveness, as said by 265 (61.48%) participants and side effects such as acne (68.13%). Conclusion: This study has indicated a low rate of awareness regarding sun exposure. Also various factors like cost, sticky consistency, need for multiple applications and climatic conditions limit widespread use of sunscreens by the general population, despite sufficient awareness. This necessitates the need for development of sun awareness policies and newer sunscreen preparations.
