IRRITATION AND MOISTURE TEST OF MOISTURIZER SERUM CIRCULATING IN BANDUNG CITY

Abstract

Serum is a popular cosmetic preparation, especially because of its lightweight, liquid form that is easy to apply and doesn’t leave any unpleasant residue. Its smooth, light texture allows it to be quickly absorbed into the skin without unwanted traces. A variety of serums are widely available and well-received, including brightening serums, anti-acne serums, anti-aging serums, and moisturizing serums. Moisturizing serums, in particular, are in high demand due to Indonesia’s tropical climate, which often leads to dry and rough skin conditions. The hot weather makes skin moisture essential, especially for facial skin, to maintain a clean, hydrated, smooth, and bright appearance. Thus, products that effectively hydrate the skin are essential. Moisturizing serums are expected to help address skin dryness caused by the tropical climate, necessitating a high level of moisture in these products. Additionally, it’s essential that these preparations are free of irritants to avoid skin irritation. This study simulates moisture efficacy and safety testing through irritation tests, using three brands of moisturizing serums sampled from online marketplaces in Bandung City
