At a glance

・Kiehl’s US has run promotions such as buy-one-get-one sets on selected favourites and Friends & Family sales of up to 50% off.
・The US site also carries the new 1cc CollaShot Plumping Serum and larger 500ml and 100ml sizes.
・Kiehl’s US only ships to US addresses. The easiest way to buy is Buy&Ship proxy shopping; if you are comfortable shopping overseas, you can also check out yourself and ship to our US warehouse, with shipping from S$9 for the first pound (Buy&Ship Shipping).

Kiehl’s began in New York, and the “Since 1851” on its logo is a mark the brand has carried ever since. Its Calendula Toner and Better Screen sunscreen are just as popular in Singapore, so why do many shoppers still order from the US site?
There are three reasons. Some bestsellers, such as the Micro-Dose Retinol Serum and the 500ml face wash, are clearly cheaper on Kiehl’s US even after fees and shipping. The US site has run promotions as generous as buy-one-get-one or half price. And it offers larger sizes that are not always sold locally. Below are five Kiehl’s US bestsellers with their US prices.
Kiehl’s US only accepts US delivery addresses. The simplest way around this is Buy&Ship proxy shopping: paste the product link and pay, and we place the order on the US site and ship it to Singapore. If you already shop overseas, you can also check out yourself, ship to the Buy&Ship US warehouse, and forward the parcel home.

Kiehl’s US vs Kiehl’s Singapore: how much do you save after fees and shipping?
The table below compares current prices on Kiehl’s US and Kiehl’s Singapore for the items where the gap is clearest. To keep the estimate conservative, each US price includes a 6% proxy service fee and a full first pound of shipping (S$9 with Buy&Ship Shipping). Where Kiehl’s Singapore does not sell a size, it is compared with the nearest size it does sell.
| Product / size | Kiehl’s US (approx. SGD) | With 6% fee + first-lb shipping | Kiehl’s Singapore | Difference |
|---|---|---|---|---|
| Calendula Foaming Face Wash 500ml | US$67 (about S$86) | about S$100 | Two 230ml bottles (460ml): S$128 | About S$28 less in the US |
| Micro-Dose Retinol Serum 30ml | US$65 (about S$83) | about S$97 | S$115 | About S$18 less in the US |
| Micro-Dose Retinol Serum 50ml | US$95 (about S$122) | about S$138 | S$155 | About S$17 less in the US |
Kiehl’s Singapore lists the face wash in 75ml and 230ml only, so the 500ml pump bottle is not sold on Kiehl’s Singapore. Ordering several items in one parcel spreads the shipping cost further.
Kiehl’s US promotions: buy-one-get-one, up to 50% off, and larger sizes
Kiehl’s US has run a range of promotions. It has offered selected favourites as buy-one-get-one duo sets, discounted some products by up to 50% during Friends & Family sales, and added free gifts above a spending threshold. Offers and eligible products change each time, so check the Offers page on the US site before you order.
Several products also come in larger 500ml and 100ml sizes on the US site, and for the same product the larger size usually costs less per millilitre, which suits anyone using it every day.
5 Kiehl’s US bestsellers and their prices
All five come from the Kiehl’s US Bestsellers list. Prices and stock were checked on 6 October 2026 and converted at US$1 ≈ S$1.28.
1. Better Screen™ UV Serum SPF 50+ 100ml
A serum-texture SPF 50+ broad-spectrum sunscreen with collagen peptide, number three on the US bestseller list. Alongside the 15ml and 50ml sizes, the US site sells a 100ml bottle, which is the better buy if you wear sunscreen every day.
Kiehl’s US: 15ml US$22 (about S$28) | 50ml US$45 (about S$58) | 100ml US$69 (about S$88)
2. Calendula Deep Cleansing Foaming Face Wash 500ml
The cleanser from the same Calendula line as the toner. Kiehl’s describes a calendula and glycerin formula that foams up with water, for normal to oily skin. The US site sells it in 75ml, 230ml and 500ml; the 500ml pump bottle is the most convenient for daily use and the best value per millilitre. Kiehl’s Singapore lists it in 75ml and 230ml only; even after a 6% fee and a full pound of shipping, the US 500ml comes in about S$28 under two Singapore 230ml bottles.
Kiehl’s US: 75ml US$21 (about S$27) | 230ml US$39 (about S$50) | 500ml US$67 (about S$86)
3. Calendula Herbal-Extract Toner 500ml
The long-running toner with real calendula petals in the bottle. Kiehl’s says the formula dates back to the 1960s; it is alcohol-free and suits normal to oily and sensitive skin. The US site sells 125ml, 250ml and 500ml, and the 500ml suits morning-and-night use.
Kiehl’s US: 125ml US$32 (about S$41) | 250ml US$48 (about S$61) | 500ml US$75 (about S$96)
4. Micro-Dose Anti-Aging Retinol Serum
Kiehl’s daily micro-dose retinol serum, with ceramides and peptide. Kiehl’s describes it as suitable for daily use with minimal discomfort, and labels it paraben-free and fragrance-free. It comes in 30ml and 50ml; if you are new to retinol, the 30ml is a sensible start. Kiehl’s Singapore sells it at S$115 for 30ml and S$155 for 50ml; with a 6% fee and a full pound of shipping, the US price is about S$18 and S$17 lower respectively.
Kiehl’s US: 30ml US$65 (about S$83) | 50ml US$95 (about S$122)
5. 1cc* CollaShot Plumping Serum
The newest launch on the US site and number two on its bestseller list. Kiehl’s describes a serum with recombinant collagen polypeptides and vitamin B12, aimed at skin that has lost firmness as collagen declines, for a visibly plumper look.
Kiehl’s US: 30ml US$55 (about S$70) | 50ml US$78 (about S$100)
*Kiehl’s US prices and stock checked on 6 October 2026 on Kiehl’s US. Prices can change at any time; the official site is the final word. Converted at US$1 ≈ S$1.28, excluding the proxy shopping service fee and international shipping.
How to buy from Kiehl’s US in Singapore: proxy shopping is the easiest route
According to Kiehl’s US shipping and returns policy, orders placed at kiehls.com ship only to addresses within the US (plus US territories and APO/FPO addresses). There is no international shipping, so an address in Singapore cannot be selected at checkout.
With Buy&Ship proxy shopping, you do not need a US address or a US checkout. Paste the Kiehl’s product link into the proxy shopping form, choose the size and quantity, then confirm the quote and pay online. We place the order on the US site, it arrives at our US warehouse, and we ship it on to Singapore. Proxy shopping carries a service fee from 6% of the item price; your quote shows the exact amount.
If you already shop overseas, you can also check out on the US site yourself, using the Buy&Ship US warehouse as the delivery address, then forward the parcel home and skip the service fee. The comparison table below sets out the differences.
What does it cost in total? Better Screen 100ml plus Retinol Serum 50ml
Take a proxy order for the Better Screen UV Serum 100ml and the Micro-Dose Retinol Serum 50ml: US$164 in total, which is above the US$50 free-shipping threshold, so there is no US domestic shipping to pay.
| Item | Cost (SGD) |
|---|---|
| Products: Better Screen 100ml US$69 + Retinol Serum 50ml US$95 = US$164 | about S$210 |
| Kiehl’s US domestic shipping (free over US$50) | S$0 |
| Proxy shopping service fee (from 6% of item price) | about S$13 or more |
| International shipping (about 1.5 lb with Buy&Ship Shipping, S$9 first lb + S$7/lb) | about S$13 |
| Estimated total | about S$236 or more |
Buy&Ship Singapore’s US-warehouse shipping is charged by actual weight. Buy&Ship Shipping is S$9 for the first pound and S$7 for each additional pound. UPS is S$10 for the first pound and S$6 for each additional pound, but UPS charges a minimum processing fee of S$23.60 on each shipment worth S$400 or less, so for a typical skincare order, Buy&Ship Shipping usually works out cheaper. See the pricing page for the latest rates.
Tip: Kiehl’s US ships free within the US on orders of US$50 or more, and charges US$8 below that. Combining several products in one order avoids the domestic fee and lets them travel to Singapore as one parcel, which costs less than shipping them separately.
Kiehl’s proxy shopping vs. ordering yourself and forwarding
For most readers, proxy shopping is the simpler choice: no US checkout to deal with and no worries about whether your card will go through. If you are an experienced overseas shopper who wants to skip the service fee, ordering yourself and forwarding is the alternative.
| Buy&Ship proxy shopping | Order yourself + US warehouse forwarding | |
|---|---|---|
| Who places the order | Buy&Ship orders for you on the US site | You order on the US site |
| US-only delivery | Handled for you; we send it to our US warehouse | Use the Buy&Ship US warehouse as the delivery address |
| Payment | Confirm the quote and pay online | Pay in USD on the US site; your card must be accepted |
| Cost | Product price + service fee (from 6%) + international shipping | Product price + international shipping |
International shipping costs the same either way and is generally charged by actual weight. The difference is who places the order, and whether a service fee applies.
Before you order from Kiehl’s US
Check the restricted items list before buying other skincare
Some skincare products cannot be shipped because of their ingredients. Before buying anything beyond these picks, check the full ingredient list on the product page (“See full list”) against our restricted items list, and contact Customer Service before ordering if you are unsure.
Fragrances and sprays are restricted too
The restricted items list also covers perfumes and other scented products, products containing alcohol, flammables, and aerosols. Check the restricted items list before ordering Kiehl’s fragrances or spray products.
Watch for promotions, and go for the larger sizes
Kiehl’s US buy-one-get-one and discount events come and go, so check the Offers page before you order. If you are using proxy shopping, ask Customer Service before ordering whether a current promotion can be applied. For the same product, larger sizes usually cost less per millilitre.
Protection for liquids and glass bottles
Every parcel comes with free basic protection, but fragile items and liquids have limited cover. Most skincare is liquid, and some comes in glass, so see the FAQ on the pricing page or ask Customer Service for details.
