Formulation and Evaluation of Herbal Sunscreens: An Assessment Towards Skin Protection from Ultraviolet Radiation

Abstract

Sunscreen lotion is a sort of product that protects against the sun's harmful rays by containing ultraviolet radiation (UV rays), which is divided into two types: ultraviolet radiation A (UVA) and ultraviolet radiation B (UVB). The incorporation of herbal materials into sunscreen is one of the most effective and natural ways to protect against the sun, as measured by the sun protection factor (SPF), as well as the detrimental side effects of toxic chemicals. The present study aimed to develop herbal sunscreens containing turmeric (strong antiseptic property which protects skin from bacteria caused by excess sweat), coconut oil (used as a sun-block agent and helps to protect skin from sun damage), aloe vera (give a cooling effect to the skin and work as skin barrier), lemon (used to protect skin for sunburn) which will be effective for skin and protect skin against harmful sun rays, sunburn, and skin cancer. Prepared herbal sunscreens were evaluated for physicochemical characteristics, SPF, thermal stability, antioxidant activity, in vitro mutagenicity, and stability. Results showed that the F5 and F6 herbal sunscreens were of good consistency and viscosity with excellent antioxidant, non-mutagenic, nonirritant, stability activity and possessed 33.50 SPF for normal skin. In comparison to F1 through F4, formulations with a coconut oil base and carrot seed extract (F5 and F6) were shown to be stable and effective, with a high SPF.

Development and Characterization of Methyl-Anthranilate-Loaded Silver Nanoparticles: A Phytocosmetic Sunscreen Gel for UV Protection

“…To prevent sunburn, experts advise applying sunscreen to block UV rays and limiting your exposure to the sun. Sunscreen formulation efficacy is measured by its capacity to shield skin from the sun’s ultraviolet (UV) rays, and its performance is determined by its sun protection factor (SPF) [ 27 ]. TiO 2 and ZnO can protect against and lessen UV irradiation-induced damage by reflection, scattering, and absorption, respectively [ 28 , 29 ].…”

Novel Topical Formulations Based on O. Basilicum and T. Pratense: Antioxidant, Antimicrobial, and Anti-Inflammatory Effect

“…It has been estimated that the renewal time of the human epidermis is on average 40 to 56 days. The capacity for cell renewal declines rapidly with age, but this process can be slowed down or even reversed by some phytochemicals, which protect the skin by quenching free radicals and reducing inflammation through the inhibition of NF-κB [2,3]. Among the phytochemical agents, phenolic compounds constitute a group of secondary metabolites that have important functions in plants.…”
