My secret for getting the US-exclusive Summer Fridays Birthday Cake balm shipped to South Korea

The Birthday Cake balm obsession of 2026

It is February 2026, and my social media feed is dominated by one specific item: the Summer Fridays Lip Butter Balm in the limited-edition Birthday Cake scent. While my friends in France are posting TikToks about how impossible it is to find locally, I realized early on that this specific anniversary release remains a US-exclusive. For those of us in South Korea who crave that signature clean aesthetic and high-performance hydration, the struggle to get our hands on a single tube is real.

More about shipping to South Korea

The hype is not just about the scent. This balm has become a status symbol for the 'clean girl' aesthetic that remains massive in Seoul. However, because it is out of stock or simply not released in our local markets, I had to look toward the original source: US retailers like Sephora and the official Summer Fridays webstore.

How I buy from US stores while living in Seoul

I have learned that the most reliable way to secure these drops is to shop US store sites directly. Since these brands rarely offer direct international shipping to South Korea—or if they do, the costs are astronomical—I always use a freight forwarder. By using a freight forwarder, I get access to a tax-free US address in Oregon, which saves me from paying US sales tax on top of the product price.

When I forward packages from the US, I can often consolidate multiple beauty finds into one shipment, which makes the cost of international shipping much more manageable. If you are curious about the potential costs before you buy, I highly recommend checking the shipping calculator to see how it fits your budget.

The BuyForMe solution for difficult US retailers

One of the biggest hurdles I encountered when I first started proxy shopping was the dreaded order cancellation. Many high-end US beauty brands and major retailers like Sephora are known to block international credit cards or flag orders sent to known shipping hubs. There is nothing more frustrating than seeing a "Birthday Cake Edition" balm in your cart only to have the transaction declined because your card was issued in South Korea.

This is where the "BuyForMe" service becomes a lifesaver. When I cannot get my own payment method to clear, I use comGateway’s buy for me service. We essentially tell them what we want, and they purchase the item on our behalf using a US domestic credit card. It is the most effective way I have found to guarantee that my order actually ships. It takes the stress out of proxy shopping and ensures I do not miss out on limited-edition drops that sell out in hours.

Shipping estimates and box details

Before you hit the checkout button, it helps to know what you are dealing with in terms of logistics. A lip balm is small, but the way it is packaged matters for your final cost. Here is what I estimated for my recent order:

Always keep an eye on the prohibited items list just in case you are tempted to add aerosols or perfumes to the same box, as those have much stricter shipping rules.

South Korea delivery and import tax rules

Getting your South Korea delivery right means understanding the customs landscape. For goods coming from the USA, we benefit from a de minimis threshold. Usually, if your total order value (including US domestic shipping) is under $200 USD, you can avoid import tax under the KORUS FTA. However, if you go over that $200 limit, be prepared to pay VAT and duties upon arrival.

I find that using a professional package forwarding service makes the customs declaration process much smoother. They help ensure the paperwork is correct so my package doesn't get stuck at Incheon. Whether you prefer DHL international shipping for speed or FedEx international shipping for reliability, having a partner to ship to South Korea makes the process of owning US-exclusive beauty products feel effortless.
