For most skincare enthusiasts, serums are an essential part of the perfect beauty routine. Whether it’s your nightly hyaluronic acid application or your weekly salicylic treatment, these skincare heroes can be super effective when trying to achieve clearer skin. 

But buying serums can often put a huge dent in your wallet, especially when the products you choose run for hundreds of dollars. And let’s face it, serums can get pricey.

Although celebrity-approved items or cult-favorites can be super effective and fun to use, there are many options on Amazon that are just as great — and half the price.

After scouring the internet and going through trial-and-error, I’ve found some amazing serums that work just as great as higher-end options. And while it’s understandable to splurge on skincare, you definitely don’t have to with these effective, top-rated and under-$20 hidden gems on Amazon.

From tackling dryness to aiding in healing acne, I’ve compiled a list below of your potential new skincare favorites. And fun fact: Many of these serums are popular buys among In The Know readers.
