Buy It For Me

Just a moment, securing your connection...

This refill is twice the size of the standard bottle but comes at a significantly better price-per-milliliter. For those who use Buffer every day, the 100ml size is the logical choice. However, there is a catch for those living in Hong Kong: this specific jumbo size is currently a US-site exclusive. Most international retail partners only carry the standard 50ml size, leaving global fans looking for a way to shop us store options directly.

Why the slugging community in Korea and Hong Kong is obsessed

Slugging—the practice of coating your face in an occlusive layer at night—has been a staple in Korean beauty routines for years. In Hong Kong, where air conditioning can strip the skin of moisture overnight, slugging is equally popular. The Experiment Beauty Buffer is frequently cited as the perfect 'slugging' base or alternative. It provides the barrier protection of petroleum jelly but with added skin-identical ingredients like ceramides and squalane.

Social media threads are filled with users showing off their 100ml refills, often calling it the only product that keeps their skin hydrated during the humid summers and dry winters of 2026. Because it is so effective, many users prefer to buy in bulk. This is where a freight forwarder becomes a necessary part of the beauty routine, as it allows fans to access the full US inventory that isn't available locally.

How to buy from the US store from Hong Kong

Buying directly from the Experiment Beauty US website is the only way to secure the 100ml Jumbo Refill. While the process seems straightforward, international shoppers often face hurdles. Many US-based skincare brands do not offer direct international shipping to Hong Kong, or if they do, the costs are prohibitive. By using a parcel forwarding service, you can get a tax-free us address to use at checkout, which often saves a significant amount on the initial purchase.

Before you place your order, it is a good idea to use a shipping calculator to see how much it will cost to bring your items home. Skincare bottles can be heavy, especially when you are ordering multiple 100ml refills. Knowing the weight and dimensions helps in planning your budget for the year.

The reality of credit card declines at US stores

A common problem for shoppers in Hong Kong is the strict payment security used by US retailers. Stores like Experiment Beauty, or larger giants like Nike, Sephora, and Apple, often block orders placed with international credit cards. Even if your card is valid, if the billing address doesn't match a US format or if the system flags the order as going to a known shipping hub, the transaction is often cancelled immediately.

This is where the comGateway "BuyForMe" service becomes essential. Instead of risking a cancellation, you can use this assisted purchase service. The process is simple: you tell us what you want to buy, and we use a US domestic credit card to make the purchase on your behalf. This is the safest way to ensure your Experiment Beauty Jumbo Refill order is confirmed and processed. It eliminates the frustration of seeing a "Transaction Declined" message after you have spent time hunting for stock. Using a domestic US card makes the retailer treat the order like any other local purchase, providing a seamless experience for the shopper.

Getting your skincare haul to Hong Kong in 2026

Once your package arrives at your US address, you can manage how it gets to Hong Kong. If you have questions about prohibited items or liquid restrictions, the FAQ section on our site provides clear answers. Generally, skincare products like Buffer are easy to ship, but it is always best to check the latest regulations for 2026.

You can also review the international shipping rates to choose between express or standard delivery. For many in Hong Kong, consolidation is the preferred method. You can wait for several US orders to arrive at your address and then ship them together to save on the base shipping fee. This makes the 100ml refill even more cost-effective, as you are maximizing the weight of your shipment. Whether you are a skincare minimalist or a dedicated slugging enthusiast, getting your hands on the right products shouldn't be limited by your location.
