Is the Tower 28 SOS 16oz refill actually a genius move or am I just mist-taken about my Swiss savings?

Why I'm obsessed with the 16oz SOS refill

My skin has a love affair with hypochlorous acid, but my bank account usually hates the constant restocking of small bottles. When Tower 28 dropped the 16oz SOS Daily Rescue Facial Spray Value Size Refill on April 22, 2026, I knew my bathroom cabinet needed a massive upgrade. This refill is essentially four of the standard bottles for a fraction of the price, making it the most cost-effective way to keep my skin calm during the dry Swiss winters.

I realized quickly that this specific jumbo size is a US-only exclusive for now. Retailers in Europe haven't stocked the 16oz beast yet, which left me wondering if I could bridge the gap between a US warehouse and my doorstep in Zurich without losing my mind.

My secret to grabbing US exclusives

I don't let geography dictate my skincare routine. To get my hands on this, I had to shop US store websites that don't typically offer direct international shipping to my region. My solution was to use a freight forwarder to provide me with a US-based address. This way, I could purchase the refill from Sephora or the Tower 28 official site as if I were living in the States.

We often find that these value sizes are designed to keep domestic customers loyal, but by using a tax-free US address, I managed to avoid US sales tax before the item even started its journey to me. It's a little loop I've learned to love for my high-end beauty hauls.

Shipping estimates for my Swiss haul

Before I clicked 'buy,' I needed to know if the shipping costs would eat up all my savings. I used a shipping calculator to get a rough idea of the damage. Here is what I found for the Tower 28 16oz refill:

Because the item is a liquid, I checked for any restrictions. Thankfully, hypochlorous acid sprays aren't flammable, so they don't fall under the same harsh 'dangerous goods' categories as perfumes or aerosol cans. This makes the Switzerland delivery much smoother and cheaper than I originally anticipated.

My step-by-step forwarding process

I get a lot of questions about how I actually manage this. I followed a simple how it works guide that involves three main steps. First, I sent my Tower 28 order to my comGateway address in Oregon. Since Oregon has no sales tax, I saved about 7-10% right off the bat.

Once the 16oz bottle arrived at the warehouse, I received a notification. I chose to forward packages immediately, but sometimes I wait and combine it with other US finds to save on the base shipping fee. My experience shows that consolidating two or three items is the sweet spot for the best value.

Dealing with Swiss import taxes

I always keep an eye on the total value of my shipment. When I buy from US ship to Switzerland, I remember that the Swiss VAT (currently 8.1%) and the Swiss Post handling fees apply if the tax amount exceeds 5 CHF. Since the 16oz refill is priced around $68 USD, I knew I would likely have a small bill to pay upon arrival.

However, even with the shipping fee and the Swiss VAT, I am still paying significantly less per ounce than if I bought four 4oz bottles locally in Europe (if I could even find them!). I've found that being proactive and using a reliable parcel forwarding service removes the guesswork from the process. My skin is hydrated, and my wallet isn't crying—that's what I call a win for 2026.
