Frequently Asked Questions
Can I trust buying Korean skin-care products online?
Yes, but where you shop matters—and thankfully, getting your hands on authentic K-beauty in the US is easier than ever. The new Olive Young x Sephora collaboration gives shoppers another mainstream way to discover Korean brands without having to navigate third-party sellers or international shipping. Other trusted options include stateside K-beauty retailers such as Soko Glam, as well as Asia-based retailers like YesStyle, though international orders may take longer to arrive. Amazon carries a huge selection, too, but it requires a little more homework: Sellers and inventory can change frequently, so at Allure, we only include products sold directly by Amazon or the brand itself at the time of writing. (And keep in mind that the listed seller may be a brand’s parent company—for example, Dear Klairs products may be sold by Wishtrend.)

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 best Olive Young x Sephora collaboration products, 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 dermatologists.

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.
