Choosing the right sunscreen for your skin type can be challenging due to the wide variety of products available and differences in skin types among users. This study aims to develop a web-based Decision Support System (DSS) to recommend the right sunscreen product using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. This system uses five criteria, namely: Broad Spectrum Protection, SPF Value, Skin Compatibility, Comfort of Use, and Skin Safety. The TOPSIS method is applied to perform normalization, weighting, calculation of ideal solutions, and ranking of alternatives. The results of the study show that the system is able to provide objective sunscreen recommendations based on user preferences, thereby helping users make more accurate and structured decisions.
