For most skincare enthusiasts, serums are essential in creating 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. 

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

Although celebrity-approved items or cult-favorites can be super effective and fun to use, I’m here to tell you, and your bank account, that 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 splurging on skincare is totally understandable, there are a ton of hidden gems on Amazon that you may have not considered before that are effective, top-rated and under $20. Some have even garnered loyalists who refuse to use anything else and others have more than 14,000 customer ratings. So yes, the ultimate skincare regimen does not have to break the bank.

From tackling dryness to fighting signs of aging, I’ve compiled a list below of your new favorite go-tos. And fun fact: some of these products have been the most-purchased items among In The Know readers.
