Why it’s worth it: There aren’t many microcurrent devices we consistently reach for—tools are often an investment, after all—so when one makes the cut, it’s usually doing something right. Medicube Age-R Booster Pro stands out for keeping things refreshingly simple: no attachments, no conductive gel, just the device and your favorite serum. It packs four modes into one sleek tool, including Booster Mode (electroporation) to enhance skin care absorption, MC Mode (microcurrent) to target fine lines, Derma Shot Mode (EMS) to firm and contour, and Air Shot Mode to improve pore elasticity. Switching between modes is as easy as pressing a button, but testers say MC Mode is the real standout for its jaw-snatching results.
“I must say: This is the most powerful device I have ever used. Setting three out of five had my muscles twitching (in a good way). I also like that it has a screen that tracks the time, so I don’t have to keep track of beeps. I find the user experience is better than many microcurrent devices I’ve used in the past.” —Jessica Cruel, editor in chief

Frequently Asked Questions
Can I trust buying Korean skin-care products online?
Yes, as long as you’re thoughtful about where you’re buying from. Korean skin-care products are widely available online, including on Amazon, but it’s important to do a bit of due diligence on the seller. Listings, pricing, and third-party vendors can change frequently, so it’s best to purchase items sold directly by the brand or by Amazon itself. (Note: Sometimes the seller appears under a parent company name—for example, I’m From products are sold by Wishtrend.) You can also shop through trusted, stateside K-beauty retailers like Soko Glam, which carefully curates its selection, or Asia-based sites such as YesStyle and Olive Young—though orders from overseas may take a bit longer to arrive.

How we test and review products
When Allure tests a product, our editors look at it from every angle in an effort to best serve you. We review ingredients, scrutinize brand claims, and, when necessary, examine peer-reviewed scientific and medical studies. In addition to testing each and every product that’s included in each and every review, we rely on experts who shape their fields, including dermatology, cosmetic chemistry, and medicine, to help us vet the ingredients and formulas.
For our list of our readers’ favorite K-beauty products, we looked at Amazon order data to identify the K-beauty products that our readers shop (through our affiliate links) the most. As you can see, based on our quotes and video demos, we have tested and recommended all of these fan-favorite products ourselves over the past year. For that process, we considered each product’s performance across five primary categories: product ingredients and efficacy, packaging, fragrance, texture, and product wear. Every product was determined to have excelled in each category by our editorial team, which is composed of in-house writers and editors as well as contributors, along with special consideration from board-certified dermatologists, estheticians, and brand founders.

Our staff and testers
A beauty product is a personal purchase. You might be searching for a face cream to address persistent dryness or a new nail product to add to your Sunday self-care routine; you may simply be browsing around for the latest launches to hit the hair market. No matter what you seek or your individual needs and concerns, Allure wants to ensure that you love anything we recommend in our stories. We believe that having a diverse team of writers and editors—in addition to the wide range of outside testers and industry experts we regularly call upon—is essential to reaching that goal.
After all, can we really say a skin-care product is the “best” for people over 50 if the only testers we’ve solicited opinions from folks who have yet to hit 30? Can we honestly deem a high-end diffuser worthy of your hard-earned cash if it’s never been tested on curls? We’re proud that our staff spans a wide range of ages, skin tones, hair textures, genders, and backgrounds, which means that we are able to fairly assess any beauty product that comes into the beauty closet.
