Pharmacological Review Of Chemical Agents Used In Sunscreen Preparations

Abstract

Prolonged exposure toUV radiation has been shown to cause skin disorders like sunburn and skin ageing etc. Sunscreens have been
shown to be beneficial effects on lowering the prevalence of skin disorders (sunburn, skin aging, and immunosuppression) because of
their chemical properties to absorb, reflect, and scatter UV radiation.A ton of commercial products have hit the marketin the last two
decades, made from traditional organic and inorganic UV filters. These products, in particular, have been enhanced with a number of
superior properties that protect against the harmful effects of ultraviolet radiation.Sunscreen is defined as a substance that shields the
skin from the sun's ultraviolet radiation. Because of their ability to prevent UV-induced sunburns (the sun protection factor -SPF),
sunscreen is frequently recommended for sun protection.It aids in the prevention of sunburn and the reduction of sun-related ill effects
such as premature skin ageing and skin cancer. They are routinely tested in humans and given a sun protection factor (SPF) that reflects
their ability to prevent sunburn.The following review discusses the pharmacology of various chemical agents used in sunscreen
preparations for sun protection. Physical and chemical sunscreen agents are the two types of agents. Physical agents that block sunlight
and chemical agents that absorb sunlight are listed and explained. The sun protection factor(SPF) is the calculated as the efficacy of
the sunscreen formulation. Understanding the pharmacology and chemical properties of various sunscreen agents is essential to develop
a better formulation. Shifting paradigm towards the herbal ingredient to reduce the side effects of chemical agents can be a promising
future aspect.
