Table of Contents

Introduction

Sunscreen is a vital part of our daily skincare routine. It protects our skin from harmful UV rays that can cause sunburn, premature aging, and even skin cancer. With increasing skin health awareness, using sunscreen has become more critical than ever. However, not all sunscreens are created equal, and understanding what goes into them can make a big difference.
