Abstract
The effect of glycolic acid to the effectiveness of sunscreen products with oxybenzon and octyl methoxycinamate as the active ingredients has been investigated. The indicator of the sunscreen effectiveness was Sun Protecting Factor (SPF) value. Five formulas of sunscreens product with different concentrations of glycolic acid 0 %, 9 %, 10 %, 11 % w/w and the cream base as control were made. The measurement of the SPF value was done by Petros Spectrophotometry method. The result showed that glycolic acid increased the effectiveness (SPF value) of the sunscreen products that their moderate protection effect changed to maximal protection effect. The optimum concentration of glycolic acid can be reached at 9 % w/w .
