Is importing the Tower 28 16oz refill to Hong Kong actually worth the cost?

Why everyone is talking about Tower 28

I recently noticed my social feeds blowing up with reviews of the Tower 28 SOS Daily Rescue Facial Spray. It seems like every skincare enthusiast in Taiwan is obsessed with it for managing sensitive skin and maskne. After doing some digging, I realized that while we can find the smaller bottles locally, the real prize is the 16oz jumbo refill. This massive size is currently a US-exclusive, making it a bit of a challenge for those of us living in Hong Kong to get our hands on without a little help.

Just a moment, securing your connection...

My skin has been acting up lately, and the hypochlorous acid in this spray is supposed to be a miracle for redness. I wanted to see if I could secure the best price-per-ounce by shopping directly from US retailers like Sephora or the official Tower 28 site, rather than paying the marked-up prices from local resellers who only carry the 4oz bottles.

The math behind the 16oz jumbo refill

When I calculated the costs, the difference was surprising. A standard 4oz bottle often retails for a significant amount when you factor in the reseller premium in Asia. However, the 16oz refill bottle in the US provides four times the product for a much lower relative price. Even with the cost of international shipping, the bulk purchase seems to make more sense for my daily routine in 2026.

I found that by using a tax-free US address, I could avoid US sales tax entirely, which adds up when you are buying multiple skincare staples at once. It’s the only way I’ve found to get the genuine jumbo size without waiting for a friend to visit California.

How I order from the USA

To get my package safely to my door, I used a freight forwarder. The process was much simpler than I expected. I just signed up for an account, got my personal US address, and used that at the checkout of the US store. Once the store shipped my Tower 28 refill to the warehouse, I received a notification to forward packages to my home in Hong Kong.

I always make sure to use a reliable international shipping service because liquids can sometimes be tricky with customs if the paperwork isn't handled correctly. My experience with comGateway has been smooth so far, especially since they understand the specific requirements for Hong Kong delivery.

Shipping estimates for Hong Kong

If you are planning to buy the Tower 28 16oz refill, here is what I estimated for the logistics side of things. Knowing these details helped me use the shipping calculator more accurately before I hit the buy button.

I recommend checking the latest international shipping rates before finalizing your cart. If you add a few more items, like a cleanser or a moisturizer, the shipping cost per item usually goes down, which is how I justify my little hauls.

Why volumetric weight matters

While the Tower 28 spray is relatively compact, I always keep an eye on the box size. If you decide to buy the jumbo refill along with something very light but bulky—like a pack of cotton rounds or a large makeup sponge—the shipping cost might increase because of the box volume. I usually stick to heavy, small items to get the most out of my international shipping budget.

My final verdict on the savings

So, is it worth it? For me, the answer is yes. By choosing to ship to Hong Kong directly from the US, I saved about 30% compared to buying four individual smaller bottles from local specialty shops. Plus, I have the peace of mind knowing the product is fresh and directly from the source.

I suggest you use the shipping calculator to see if the numbers work for your specific order. For anyone with chronic skin sensitivity who uses this spray as much as I do, the 16oz refill is a logical choice for 2026. If you are tired of running out of the 4oz bottle every three weeks, this is the way to go.
