Skin Erythema Sunscreen Photo Protection
Abstract

Solar ultraviolet type B radiations (UVB) is fundamentally liable to be absorbed by keratinocytes leading to production of free radicals or reactive oxygen species (ROS) which might cause skin erythema, sunburn, skin cancer and premature ageing. Herbal sunscreen guard skin from sun’s radiations which reduces sunburns with reduced risk of skin harms. Antioxidants quench free radicals and ROS which might aid photo-protection effect. This review compiled previously patented herbal photo protection compositions and sunscreens.

Introduction

Solar ultraviolet radiations at the earth’s surface encompass approximately 95-98 % UVA and 2-5 % UVB. The frequency of ultraviolet type B is fundamentally liable to be absorbed by keratinocytes leading to production of free radicals or reactive oxygen species (ROS) which might cause skin erythema, sunburn, skin cancer and premature ageing [1, 2]. Anti-oxidants quench free radicals and ROS which might aid photo-protection effect. Herbal sunscreen topical products guard skin from sun’s radiations which reduces sunburns with reduced risk of skin harms. This review compiled previously patented herbal photo protection compositions and sunscreens. Few herbal photo protectants have been represented in Figure 1.

Ultimate Characteristics of Sunscreen Product

A high-quality sunscreen ought to absorb or riddle out the sunburn emission causing and must be non-toxic and non-irritating. It should be stable under air, light and moisture. Moreover, it must be moderately non-volatile, subsequently will not evaporate [3]. Herbal sun protection compositions and sunscreens patented for patented for sunscreen and photo protection activity has been listed in Table 1, 2, respectively.
