Abstract

Excessive frequency and duration of UV exposure causes adverse effects, including erythema, pigmentation, premature aging, and even skin cancer. Therefore, additional protection is required, such as the use of sunscreen. The development of natural active ingredients is necessary to reduce the negative impact of sunscreen products. Tahongai (Kleinhovia hospita L) contains flavonoid compounds that have the potential as sunscreens due to the presence of chromophore groups that can absorb UVA and UVB rays. The purpose of this study was to determine the potential of tahongai leaf infusion as a sunscreen. The test method of sunscreen activity was carried out in-vitro using UV-Vis spectrophotometry. The sunscreen activity test was carried out by calculating the percent transmission value (%Te), the percent transmission value of pigmentation (%Tp), and the SPF value. The results of the calculation of %Te, %Tp, and SPF values, as well as the sunscreen category at a concentration of 0.5 g are %Te of 3.368 (extra protection), %Tp of 1.248 (sunblock), and SPF value of 21.945 (ultra protection). Tahongai leaf infusion has potential as an active ingredient for sunscreen products and still requires further in vivo research to ensure its effectiveness as well as the duration of its protection
