As consumers become savvier about skincare, many people are looking for single-ingredient serums that provide them more flexibility to decide what goes into their skincare routine. With a single-ingredient serum, you know exactly what you’re getting, and you don’t have to worry about overexposure if two products contain the same strong ingredient.
Another benefit of single-ingredient serums is the freedom to experiment that they provide. When you use a single-ingredient product, you can perfectly pinpoint where the improvement (or lack thereof) comes from. Single-ingredient products are great for testing new ingredients the way a scientist runs an experiment — by only change one factor at a time.
