The step-by-step layout I built to get the Tower 28 16oz refill to South Korea

The foundation of my skincare needs in 2026

It is February 2026, and if you are living in Seoul or anywhere else in South Korea, you know that the humidity struggle is constant. My skin has been particularly reactive lately, and I realized that my usual 4oz bottle of Tower 28 SOS Daily Rescue Facial Spray was disappearing way too fast. We skincare enthusiasts often talk about hypochlorous acid as a hero ingredient for irritation, but buying those small bottles repeatedly felt like I was throwing money away.

I started looking at what was happening in the US market to see if there were better options. While keeping up with us trends, I noticed that Tower 28 released a massive 16oz refill bottle. The catch? It is a US exclusive. It is not available in our local shops here in Korea, which meant I had to build a specific plan to get it across the ocean.

Why the 16oz refill is the only logical choice

When I sat down to look at the numbers, the 16oz refill made so much more sense than buying individual bottles. I love the SOS spray because it mimics our white blood cells to fight bacteria and inflammation, but at the rate I use it for "maskne" and post-gym redness, I need volume.

By switching to the 16oz refill, I am essentially cutting my costs by nearly 40% compared to the standard bottle. This is the kind of efficiency I look for when building my yearly beauty budget. Plus, it is much more sustainable to refill my existing spray bottle than to keep buying new plastic packaging.

Mapping the source: Where to buy from the US

The first step in my plan was finding a reliable vendor. Sephora and the official Tower 28 website are the primary sources for this value-sized bottle. However, as many of us have experienced, trying to shop us store sites from South Korea isn't always straightforward. While these stores have the best popular products, they don't always make it easy for international fans to check out.

I decided to use a tax-free us address in Oregon provided by my favorite freight forwarder. This meant I wouldn't have to pay US sales tax, which further increased my savings on the $68 bottle.

The major hurdle with US payment systems

This is where my initial plan hit a snag. I tried to use my Korean issued credit card on Sephora, and the order was cancelled within ten minutes. Then I tried the Tower 28 site, and the same thing happened. It turns out that many major US retailers have strict security filters. They often block international credit cards or automatically decline orders that are being sent to a known freight forwarder.

It is incredibly frustrating to have the funds and the desire to buy a product, only to be stopped by a digital wall. I knew I needed a more robust solution to ensure my 16oz refill actually left the warehouse.

The BuyForMe blueprint: My secret to guaranteed delivery

To get around the payment blocks, I turned to comGateway's BuyForMe service. This was the turning point in my procurement plan. Instead of me trying to force my card through, the proxy shopping team at comGateway handled the purchase for me.

The process was simple: I provided them with the link to the Tower 28 refill and the quantity I wanted. They used a US domestic credit card to buy the item on my behalf. Because the transaction looks like a local US purchase, it bypasses the filters that usually flag international shoppers. I've found that this assisted purchase method is the safest way to guarantee their order doesn't get cancelled by difficult stores like Sephora or Nike.

Final assembly: Shipping from a tax-free US address

Once the 16oz refill arrived at my Oregon address, it was time to move it to Seoul. Before I gave the green light, I used the shipping calculator to estimate shipping cost. I always recommend doing this so you aren't surprised by the final bill.

I also took a look at the international shipping rates to decide which courier service suited my timeline. Since I was already running low on my current spray, I opted for a faster express option. Even with the shipping fees, the total cost was still significantly lower than what I would pay for four separate 4oz bottles if they were even available locally.

Import rules for South Korea delivery

When you buy from US ship to South Korea, you have to be mindful of customs. For the year 2026, the threshold for duty-free imports from the US remains at $200 (including the cost of the goods and domestic US shipping). Since my Tower 28 refill was only $68, I was well within the limit and didn't have to pay any additional import taxes.

If you are planning to add more items to your shipment, just keep an eye on that $200 cap to avoid extra charges. If you have questions about specific items, the help center or the FAQ section on the comGateway site usually has all the answers regarding South Korea delivery.

My package arrived in Seoul just six days after it left the Oregon warehouse. I now have enough SOS spray to last me through the rest of the year, and I didn't have to stress about a cancelled order. If you've been struggling with US stores, I highly suggest trying this layout for your next haul.
