Abstract

Retinol adalah bentuk aktif dan turunan generasi pertama dari vitamin A yang yang memiliki banyak manfaat untuk perawatan kulit, seperti memperbaiki tekstur kulit, merangsang pembentukan kolagen, dan mengatasi masalah penuaan serta jerawat yang membuat retinol banyak dibuat dalam sediaan kosmetika. Namun, stabilitas retinol dalam sediaan kosmetik memiliki banyak tantangan karena rentan mengalami degradasi akibat paparan faktor eksternal yang dapat memicu efek toksisitas retinol. Sehingga, review ini bertujuan untuk mengidentifikasi faktor-faktor yang dapat meningkatkan stabilitas retinol dalam sediaan kosmetik. Melalui kajian literatur dari 15 jurnal internasional dalam kurun waktu 10 tahun terakhir, ditemukan bahwa penambahan berbagai eksipien dan zat aktif lain dalam formulasi, penggunaan berbagai metode pembuatan seperti emulsi, enkapsulasi mikropartikel dan nanopartikel dengan beragam matriks, serta pemilihan kemasan yang sesuai dapat secara signifikan meningkatkan stabilitas retinol.

Abstract

Antioxidants protect the skin from the adverse effects of free radicals, which can potentially trigger premature aging and even skin cancer. Free radicals, with unpaired electrons, are highly reactive and can damage cellular structures. However, the high risk of side effects from synthetic antioxidants, such as skin cancer, has increased interest in natural sources. In cosmetic formulations, gel preparations are highly favored because they can optimally and stably deliver active ingredients to the skin. This study employed a literature review method by examining and collecting articles from relevant scientific journals published over the past 10 years (2014–2024), with 13 articles as primary references. The analysis found that several extracts, such as leilem leaf, pandan, and green tea, exhibited strong antioxidant potential, as indicated by low IC50 values, making them ideal as active ingredients in gel formulations. In addition to the type of plant leaves, the effectiveness of these antioxidants is influenced by the extract concentration used, solvent selection during extraction, and the processing techniques employed in formulation.
