If you’re having trouble applying a discount code, here are a few factors to consider:

• The discount code has expired. If you received this discount code without a clear expiration date, let us know at orders@dieuxskin.com, and we’ll take a look.
• You’ve already applied a discount code to the order. Discount codes are not stackable unless otherwise noted in the promotion fine print.
• The discount code cannot be combined with a promotional item (e.g., a gift with purchase) that’s already in your cart. If you’d prefer to redeem your discount code instead of the promotional item, you can remove the promotional item from your cart and try the code again.
• The discount code does not apply to the item(s) in your cart. Special-edition items, bundles, and gift sets may be excluded from promotions.
• The discount code does not apply to subscription orders. As subscription orders are already discounted, discount codes are not applicable on subscription orders unless otherwise noted in the promotion fine print.
• Your order total doesn’t meet the USD minimum spend requirement. Our minimum spend thresholds for promotions are always based on USD amounts. If shopping outside of the U.S., check the conversion rates between your currency and USD to make sure you’re meeting the promotion’s spend requirement.
• Free shipping promotions apply to U.S. orders only. We do not offer free shipping promotions to areas outside of the U.S.

If a gift with purchase promotion is not adding, here are a few factors to consider:

• Your order total doesn’t meet the USD minimum spend requirement. Our minimum spend thresholds for gift with purchase promotions are always based on USD amounts.
• You’ve already applied a discount code to the order. Some gift with purchase promotions cannot be combined with discount codes. Please carefully review the terms of the gift with purchase promotion for restrictions.
• You’re shopping outside of the U.S. Some gift with purchase promotions do not apply to orders shipping outside of the U.S. Please carefully review the terms of the gift with purchase promotion for restrictions.

As bundles and sets are always discounted, additional discounts do not apply to bundles and sets* and only apply to individual, full-price items in your cart.

If Dieux has become a crucial step in your skincare routine, subscriptions ensure you always stay stocked up by allowing you to set up automatic product replenishments for your favorites delivered at your preferred frequency. Subscribers are given the option to receive their replenishment order every 4, 6, 8, or 12 weeks (which can always be adjusted in our self-service subscription portal here if needed). We offer tiered percent-off discounts that increase depending on the desired order frequency:

• Every 4 weeks = 12% off
• Every 6 weeks = 11% off
• Every 8 weeks = 10% off
• Every 12 weeks = 8% off

Once enrolled in the subscription program, replenishment orders are placed automatically on each scheduled date (we’ll always let you know via email and text when your upcoming subscription order will be processed, so you’re never caught off guard).

To start a subscription for a Dieux product, visit the product page of your favorite product. Instead of clicking “One-time purchase” in the buy box, click “Subscribe” and select your desired replenishment frequency.

You can make changes, additions, and upgrades to your subscription and account information (like shipping address, payment info, etc.) at any time by accessing the subscription portal here. If you need any assistance, our customer care team is happy to help at orders@dieuxskin.com.

If your subscription order is coming soon and you do not need more product right now, you can always skip your upcoming order in the subscription portal here. If you opt to skip your upcoming order, you will not be charged, and the order will not be processed. You’ll receive your next subscription order on the following scheduled date.

As long as your item is in stock, you’re free to bump up the delivery date in the subscription portal here.

Subscribers are notified of unavailable inventory a few days before their next subscription is scheduled to process. Subscribers affected by out-of-stock items have the option to skip their upcoming order or change the delivery date here. If the order is not rescheduled, the current delivery cycle is skipped, and the next order will process normally on its next scheduled date.

If your subscription features several items and one item is out of stock, the order will be skipped until the out-of-stock item is replenished. For assistance in this scenario, please contact us at orders@dieuxskin.com, and we’ll be happy to assist you in receiving your in-stock items.

Because subscription orders are already discounted, discount codes cannot stack with subscription orders unless otherwise specified in the promotion fine print.

We’re so sorry to hear that! You can cancel your subscription at any time by accessing the subscription portal here. If you need any assistance, our customer care team is happy to help at orders@dieuxskin.com. Please let us know why you’re wishing to end your subscription in a few words. We ❤️ your feedback!

No worries! Our customer care team is happy to help at orders@dieuxskin.com.

Short answer: The word “clean” in beauty has no regulated definition, so we choose not to use it. As a brand co-founded by an expert cosmetic chemist and a licensed esthetician, we formulate based on safety and efficacy instead of fear-mongering over specific ingredients. The modern “clean beauty” movement, while well-intentioned, has created a misleading equation that nature = safe and synthetic = harmful. But that’s simply not how chemistry works! In reality, toxicity is always about the dose, not the ingredient itself (see our explainer video on this here!) Water is even toxic if you consume a high enough dose. TLDR: Nuance is everything, and we’re here to go through it together.

All Dieux formulas are vegan and cruelty-free. We never test on animals, and all of our formulas are free of animal byproducts.

No, Dieux products are intentionally formulated without PFAS-containing ingredients as listed here, so we don’t need to test for them!

Yes, but not because parabens are unsafe. Science repeatedly demonstrates that parabens are safe for use in cosmetics; however, we made a business decision to formulate without them because the market has moved on from that conversation, and we’d rather meet our customers where they are. The preservatives we use instead have been vetted by our Chief Product Officer Joyce DeLemos and regulatory agencies in the U.S. and EU to be safe and play well in formulas.

At Dieux, we never want to scare you or be alarmist on things that don’t merit alarm. We are transparent on our formulas and dosing. If you have any questions or concerns on this topic, please ask us at hello@dieuxskin.com.

Most Dieux products are fragrance-free, with Baptism Gel Cleanser in Woodsy Bergamot being the only product formulated with a fragrance.

That being said, certain ingredients in any type of skincare or self-care formula have a natural scent to them. If a product has no discernible scent, what’s usually added to the formula is something called a “fragrance masking agent.” These are chemicals added to neutralize or hide the odor of the other ingredients.

While they’re fascinating (they can trick your nose to give the perception that a product is unscented), these agents can be sensitizing to the skin. This is why Dieux products do not feature fragrance masking agents. For our formulas, fragrance-free means simply that no ingredients were added to tamper with the fragrance, and no fragrance masking ingredients were added.

Every Dieux product goes through a rigorous testing process to ensure safety, stability, and proven results—no shortcuts. We start with stability testing to confirm the formula holds its texture, color, and active ingredient potency over time, followed by compatibility testing in the final packaging to make sure the product performs as intended from first use to last. Next, we conduct safety testing, including:

• HRIPT to ensure the product is non-irritating
• PET to confirm preservatives protect against mold, yeast, and bacteria
• Non-comedogenic/non-acnegenic testing to ensure it won’t clog pores or trigger breakouts
• Ocular safety testing to ensure products are safe and gentle to use around the eye area (even for products not intended for eyes as a precaution)
• For performance, we run clinical efficacy testing via third-party labs using trained graders and advanced skin analysis tools to ensure comprehensive results across a range of skin types and tones, alongside consumer perception studies to gather real-world feedback

All third-party testing is conducted at independent, validated labs to ensure unbiased results. The exact timeline varies by product, but most formulas undergo the full suite of tests before launch, ensuring every claim we make is backed by both science and user experience.

All Dieux products are formulated in-house in our Brooklyn lab—never white-label. This allows us to fully own the formula composition and have full control to optimize ingredients and delivery systems, prioritize efficacy, and create products that are differentiated from anything that exists on the market. Once formulas are finalized in our Brooklyn lab, our products are scaled up at contract manufacturers in the U.S.

Because Skin Mercy Recovery Cream is an over-the-counter moisturizer, Canada classifies it as a medicated skincare product. This means it must be regulated by Health Canada and meet a list of requirements, which includes completing a government review and registration process, receiving a Natural Product Number (NPN), and receiving a Canadian site license and foreign site registration number (FSRN) to prove that our facility is at the same standard and quality as a Health Canada Certified Facility. We are actively working to get Skin Mercy registered so we can bring it to Canada as soon as possible. Thank you for your patience!

Deliverance 3-in-1 Repair Serum contains cannabinoids, which are a class of ingredients derived from the cannabis plant. Deliverance contains three cannabinoids: cannabigerol (CBG), cannabinol (CBN), and cannabidiol (CBD), which are non-psychoactive (i.e., cannot get you high) and have clinically studied soothing, calming, and moisturizing benefits. Due to laws regarding the transportation of cannabinoids across international borders, we're unable to ship Deliverance outside of the U.S. at this time.

At Dieux, we want you to feel good about the products you purchase. While 100% recycled aluminum is always our preferred choice, we recognize plastic still plays a part in some of our packaging today and, in certain cases, plays an important role in protecting the stability and efficacy of our formulas. Rather than ignore its impact, we’re taking steps to address it while continuing to evaluate how we can evolve in the future.

Dieux is proud to be Plastic Negative Certified through our partnership with rePurpose Global. This certification is our commitment to recovering four times as much plastic waste from nature. Every piece of plastic recovered is a piece that would not otherwise have been removed or recovered from our ecosystem had it not been for our joint efforts with rePurpose Global. To read more about this partnership and its impact, check out our blog post here.

Having Plastic Negative Certified products means that we have measured our products’ plastic footprint using rePurpose Global’s measurement tool and fund the recovery of four times as much plastic waste by weight as we use in our products and packaging.

In addition to reducing our plastic footprint, this partnership enables us to support ethical wages for waste workers, strengthen waste management systems, and prevent plastic from entering nature. Our Plastic Negative certification funds verified plastic recovery at rePurpose Global’s impact project Hara Kal in Kerala, India. On our behalf, project Hara Kal employs and empowers marginalized waste workers to recover plastic that would otherwise be landfilled, burned, or flushed into our natural environment.

The $75 cart minimum doesn’t mean you have to spend more. It just means that your cart total (before discount) must be at least $75 to apply your TYB-acquired discount code.

TYB discounts can stack with some promotions, but not all. Make sure to review the promotion fine print in our emails (or on our FAQ page) or send us an email at hello@dieuxskin.com if you’re unsure of a promotion’s terms.
