FAQs

How can I get free shipping at Biotherm?

Biotherm has free standard shipping for orders of more than $120. With skincare such as Life Plankton Regenerating Serum costing $87 per 75ml, it’s not difficult to reach this total spend amount. If your order is less than $120, standard shipping costs $8.95. Your order should arrive within 3-5 working days.

Can I use more than one code at Biotherm?

No, Biotherm usually only allows one promo code per order. However, we’ve hand-tested and you can sometimes use a promo code with a free gift promotion. Currently, you can get 30% off and a free gift when you spend $80.

Which products are best for Biotherm discounts?

Generally, we’d recommend using 15% off discount codes on high-ticket items that won’t usually be on sale in the year. For Biotherm, this includes the Life Plankton Body Duo ($111) and Lait Corporal Body Duo ($69). Of course, if there’s a specific product you like, use it on that first.

Can I return a Biotherm product?

Yes, absolutely. Biotherm allows returns within 30 days from the day after your item arrives. Your item should be unused, unopened, and in its original packaging. It’s worth noting Biotherm does not pay the costs of returns unless the brand sent the wrong item, you do not want to keep a substitute for an exchange, or faulty.


Hints and Tips

Best times to shop sales: Save the most on your Biotherm purchase by shopping for specific sales dates. Our deals experts have inputted previous sales into our data system, so we can predict when this year’s will be. This includes 30% off for Lunar New Year (Feb), a 40% off sitewide sale (End Feb), 40% off for the Easter Event (April), and 25% off for Mother’s Day (May).

Newsletter discount: Sign up for the Biotherm email newsletter to get 15% off your first purchase. This a strong discount if there are no sitewide sales, and you’re a new shopper. Email subscribers will also be sent exclusive promotions and new product information, meaning you can stay a step ahead.

Special group discounts: Student and essential workers can get 30% off purchases of $150+ at Biotherm. You’ll need to verify your place of work through GoCertify for this discount code. It’s also worth noting the 30% off is available while a sale event is on, and we’ve previously seen a regular discount of 15% off.

Referral savings: Refer a friend to Biotherm and your friend will get $10 to spend on their purchase. Once your friend’s purchase is successful, you’ll also be sent $10 credit to your account. Note: your friend will need to spend a minimum of over $50.

How We Source Our Codes 

At Marie Claire, we have a dedicated team of deal experts, commercial colleagues, and editors who find and negotiate the best promo codes and coupons, as well as produce content aiming to help you shop affordably.

We have a dedicated team of 3 deal experts that are constantly sourcing and testing coupons and promo codes for some of the biggest retailers in fashion, beauty, and beyond to list on our website. They also work with affiliate networks to get a heads-up on future deals and discounts. This means we can update our pages

Meanwhile, our commercial colleagues are key to keeping good relationships with retailers. Their experience with lifestyle vouchers helps them to negotiate the best promo codes and exclusives for you.

On the pages themselves, you’ll find carefully researched saving information for all your beauty, lifestyle, and fashion purchases. Our contributing editors have years of experience in the industry and consistently update the page to reflect new ways to save. You’ll find helpful discount FAQs and saving tips which are checked and verified regularly.


What if my promo code doesn’t work?

Our team always tries to make sure any out-of-date sales or incorrect codes are not included on our coupon pages. To do this, we check a few things, including:

  • Trying the code and checking if they are valid ourselves.
  • Check we don’t have any unique, one-use codes.
  • Looking at the offer conditions to make sure you’ve got all the information.

However, there are occasions when details change or the codes may expire without us knowing. If this happens, be sure to contact us by emailing coupons.marieclaire@futurenet.com so we know.


How do we make money? 

It’s completely free for customers to use the coupon codes we have above. We’ll get a small percentage of the money spent as a commission from the retailer you shop at. As with most businesses, we do need to make money however this will never impact the price you pay. The brand will give us a small share of the profit for connecting you to them. This helps us keep going whilst saving you more money.

Simply put, the retailer makes a sale, we get a commission, and you get a discount.
