Can this medical-grade US serum really outperform my favorite Swiss skincare?

The Cult Hype Surrounding Prequel Lucent-C

I started noticing a massive surge in posts on Xiaohongshu about a brand called Prequel. In early 2026, it seems every skincare enthusiast is obsessed with their Lucent-C Vitamin C Serum. For years, I relied on high-end Swiss pharmacy brands, but the buzz around this 15% Vitamin C formula was too loud to ignore. Users are calling it a 'cult' brand because it offers clinical-strength ingredients at prices that feel far more accessible than what I usually find in Geneva or Zurich.

The serum features a stabilized 15% L-Ascorbic Acid, combined with Ferulic Acid and Ergothioneine. We know this combination is the gold standard for brightening skin and fighting environmental damage. I was curious to see if a product priced under $25 could actually rival the luxury serums I've been using.

Why I Switched to US Medical-Grade Formulas

My interest peaked when I realized that Prequel isn't just another 'clean beauty' brand. They focus on dermatologist-led, medical-grade efficacy. In Switzerland, similar concentrations often require a much higher investment. I found that the US market currently leads in providing these high-potency actives without the luxury markup. By using a freight forwarder, I can access these specific American formulations that haven't hit the European shelves yet.

How I Get Prequel Delivered to Switzerland

Since Prequel does not offer direct international shipping to my home in Switzerland, I had to find a reliable way to get my hands on it. I use comGateway to bridge the gap. They provide me with a tax-free US address in Oregon, which means I don't pay US sales tax when I shop US stores.

The how it works process is straightforward: I order the serum to my Oregon suite, and once it arrives, I am notified to ship it to my address in Switzerland. This package forwarding method has become my standard routine for all my US-exclusive beauty hauls.

Estimated Shipping Costs and Weight

When I plan my orders, I always check the shipping calculator to avoid surprises. Here is the data I use for estimating the cost of the Prequel Lucent-C Serum:

To see current international shipping rates, I recommend checking the rate table directly, as prices can fluctuate based on the carrier I choose, such as DHL or FedEx.

Overcoming Payment Blocks with BuyForMe

One challenge I occasionally face with US retailers is the 'payment wall.' Some stores are notorious for blocking international credit cards or rejecting orders that use a parcel forwarding service address. I've had my orders cancelled in the past because my Swiss billing address didn't match the US shipping location.

To solve this, I use the BuyForMe service. This proxy shopping option means comGateway buys the item on my behalf using a US-issued card. This assisted purchase is the most secure way I've found to ensure my skincare haul isn't flagged or cancelled by strict US merchants.

Handling Swiss Customs and Tax

Shipping to Switzerland means I have to be mindful of import duties. While the Lucent-C serum is affordable, the Swiss Federal Office for Customs and Border Security applies import tax (VAT) on items exceeding a certain value. I always keep my receipts ready to ensure a smooth transition through customs. If you are unsure about the local thresholds, you should check our guide on customs tax for 2026 to see if your total order value will trigger additional fees upon arrival in Switzerland.

By consolidating my Prequel order with other US purchases, I can often save on the overall international shipping fees, making the cost per item even more attractive than buying locally.
