My math on why shipping Prequel Skin Gerapy from the US actually saves money for us in Thailand

April 19, 2026

I have been seeing the Prequel Skin Gerapy Barrier Repair Serum all over my social feeds lately, and for good reason. As someone living in Thailand, our humidity can be brutal, but the constant air conditioning in our offices and malls dries out my skin barrier faster than I can say "urea." This serum, which features a massive 10% concentration of urea, has become the gold standard for chronic dryness and keratosis pilaris. In 2026, it is still a rising star because it offers pharmaceutical-grade results without the high-end boutique price tag.

The problem we face in Bangkok or Chiang Mai is that Prequel still only ships within North America. While some resellers on local platforms have stock, they often double or triple the price. I decided to take matters into my own hands and buy directly from the source in the US to ensure I was getting the fresh, authentic product.

The math of buying from the USA versus local markups

When I looked at my local shopping apps, a single 150ml bottle of Gerapy was listed for nearly 1,600 THB. If I buy it directly from the Prequel website, it costs roughly $22 USD (about 800 THB). Even with shipping costs, the savings start to add up quickly if I buy more than one bottle or combine it with other US skincare finds. I always start by using a shipping calculator to see if my haul makes financial sense.

For my last order, I bought three bottles. The total for the product was $66 USD. I used my tax-free US address provided by my forwarder, which saved me from paying US sales tax at checkout. After adding the international shipping fee, I ended up paying about 1,100 THB per bottle. That is a 500 THB saving per unit. Over a year of skincare, that is enough to fund a whole extra haul.

Shipping Estimates for Thailand

To help you plan your own budget, I have put together these estimates based on my recent experience shipping this specific serum from the US to Thailand in April 2026.

Metric Estimated Value
Box Weight Approx. 1.2 lbs (0.55 kg) for a single unit in its shipping box.
Box Dimensions Small (Approx. 8 x 5 x 4 inches).
Volumetric Warning Low. This item is dense and small, so you will likely be charged by actual weight rather than size. However, if you add large, light items like sponges or empty cosmetic bags, keep an eye on the volumetric weight.
Battery Check No lithium batteries. This is a liquid cream/serum, so it is safe for standard air freight.

Before you ship, I recommend checking the prohibited items list just to be sure there are no new 2026 restrictions on specific liquid volumes for air travel, though I haven't run into any issues with serums so far.

How I used a freight forwarder for my order

Since Prequel does not ship to Thailand, I had to use a freight forwarder. This is basically a warehouse in the US that receives my package and then sends it to my door in Thailand. I have found this to be the most reliable way to get my hands on North American exclusives.

The process was simple: I signed up for an account, got my US address, and used that address as my shipping destination on the Prequel website. Once the package arrived at the warehouse, I was notified and could choose my preferred shipping speed. Their international shipping rates are transparent, so there were no surprises when it came time to pay for the final leg of the journey.

Why I love package consolidation

One trick I have learned is to wait until I have a few things at the warehouse. If I am already paying for the first half-kilogram of shipping, I might as well add a few more items. I often grab some US-only sunscreens or tech accessories at the same time. Consolidating multiple packages into one box significantly lowers the cost per item.

Thailand customs and import considerations

Living in Thailand, we have to be mindful of the 1,500 THB de minimis rule. If your total shipment value (including shipping costs) is under 1,500 THB, you can often avoid import duties. However, with the current 2026 VAT regulations, you should expect to pay at least the 7% VAT on most imports. For my three-bottle haul, which exceeded the threshold, I factored in a small customs fee. Even with that fee, it was still cheaper than buying from a local reseller who has already baked those costs (and their profit margin) into the price.

My advice is to keep your invoices ready. If customs asks for proof of value, I just show them my order confirmation from the Prequel website. It makes the whole process much smoother.
