PENENTUAN NILAI SPF (SUN PROTECTING FACTOR) EKSTRAK ETANOL JAMUR KANCING (Agaricus bisporus) SECARA IN VITRO DENGAN METODE SPEKTROFOTOMETRI UV-VIS

Abstract

Chronic exposure to ultraviolet light from the sun will cause changes in skin structure and oxidative stress on the skin. The effects can be in the form of acute changes such as erythema, pigmentation and photosensitivity, as well as long-term effects of premature aging and skin damage. Sun Protection Factor (SPF) is a universal indicator that explains the effectiveness of a product or substance that is UV protection. Natural ingredients that can be used as UV protection are button mushrooms (Agaricus bisporus). This study aims to determine UV light protection activity in the ethanol extract of button mushrooms (Agaricus bisporus) based on the SPF values analyzed by UV-Vis spectrophotometry at wavelengths of 290-320 nm. The results showed that at concentrations of 1% and 2% had a medium SPF category with SPF values of 17,762 and 28,643. For concentrations of 3% and 4% it has a high SPF category with SPF values of 30,592 and 31,325. The higher the concentration used, the better the SPF value.

Sunscreen lip balm stick formulation containing a combination of virgin coconut oil and crude palm oil

“…The skin can naturally withstand 10 minutes of exposure to UV rays before turning red and experiencing a burning sensation. The SPF value is the duration of sunscreen protection from UV rays [18]. In the current study, the higher the concentration of CPO used, the higher the SPF value, implying that more active compounds capable of absorbing UV radiation were present.…”

“…The length of time the skin is protected by a sunscreen is largely determined by the SPF value listed on the product. Without sunscreen, the skin turns red and burns within 10 minutes in the sun [18].…”
