Luxury anti-aging serums rarely give anything away for free. Most prestige clinical brands lock their best-selling actives behind counters or full-price bottles, with testers you cannot take home. DefenAge is pushing the other direction right now.
New customers can request a trial-size tube of its headline 8-in-1 BioSerum and have it shipped to their door at no cost. There is no basket minimum and no checkout step.
The offer runs through an invitation-style VIP page instead of a public storefront coupon. That means there is no promo code to hunt for — you submit a short sample request form with your name, mailing address, and email.
We verified every detail below directly against DefenAge's official sampling page and its published terms. No purchase is required, the trial size is fixed at 0.13 fl oz, and shipping is included. This guide covers who qualifies, what the fine print says, what the sample is worth, and what to watch out for.

What Is the Deal, Exactly?
DefenAge is mailing a 0.13 fl oz trial tube of its 8-in-1 BioSerum to new customers who request one through the official VIP invitation page. There is no purchase necessary and no promo code attached.
The sample itself is the offer, and it ships to you for free. This is a sampling program, not a storewide sale: you are not getting credit toward a future order and you are not subscribing to anything.
The full-size 1.0 fl oz BioSerum normally retails for about $198, so the trial is a low-risk way to test the formula before committing to that price tier. Submit through the official VIP BioSerum invite page to be considered.
Per the official terms, the offer is "available exclusively for new customers by invitation only." If you have ordered from DefenAge before, the terms say you are outside the target group.
The "8-in-1" name refers to a multi-tasking serum format: one bottle meant to cover several skincare steps in a single application, rather than building a routine from separate actives. That positioning is why the brand can afford to mail a trial — it wants first-time buyers to experience the whole product in one go.
What's Free (or Discounted)
The sample itself: an 8-in-1 BioSerum trial tube, 0.13 fl oz.
Shipping: included at no charge — the terms state the sample "is shipped to you for free."
No promo code: the invitation link replaces a code; nothing to copy at checkout.
What is not free: the full-size 1.0 fl oz BioSerum, which retails for about $198 if you decide to buy later. The program is a trial giveaway, not a credit.
Option | Price | Size |
|---|---|---|
Trial sample | Free | 0.13 fl oz |
Full-size bottle | ~$198 | 1.0 fl oz |
Luxury serum band | ~$150–$300+/oz | Category range |
The third row is a typical prestige anti-aging range, not a quote from a competing brand. It shows where DefenAge sits and why a free trial tube is unusually generous for this tier.
Official terms, verbatim: "No Purchase Necessary… the free sample is the 8-in-1 BioSerum, 0.13 fl oz (trial size) and is shipped to you for free."
How to Claim It Step by Step
Open the official VIP BioSerum invite page in your browser.
Confirm the page still shows the free BioSerum sample offer.
Click through to the sample request form.
Enter your name, mailing address, and email as prompted.
Confirm the new-customer and US-residency checkboxes.
Submit the form and wait for DefenAge to process the mailing.
No purchase step exists, so do not enter payment details on this flow. If the page redirects to a checkout or asks for a credit card, you have left the sampling page — back out and return to the official invite link.
Stock for these luxury giveaways moves fast. The offer is capped at one per person, so there is nothing to gain from waiting; submitting early is the whole strategy.
Processing and delivery timing are not stated in the published terms, so treat the window as standard first-class mail after the brand reviews your request. If you hear nothing after a reasonable period, re-check the live invite page rather than assuming the form failed.
Who Is Eligible?
The terms spell out a short list of rules. The offer is open to legal residents of the USA who are 18 years of age or older.
It is also "exclusively for new customers," which means existing DefenAge purchasers are not the target group. One offer per person is the stated limit: "Limit one offer per person."
Duplicate requests from the same household or email are unlikely to produce extra tubes. The brand's data handling is covered in its privacy policy.
International readers, Canadian or UK residents, and anyone under 18 are outside the stated eligibility. If your shipping address is not in the United States, do not submit.
Important Fine Print to Know
Read these before you submit, because they decide whether your request goes anywhere:
Invite-only: no public coupon; only the invitation link qualifies.
New customers only: prior buyers are excluded by the terms.
USA, 18+: residency and age stated in writing.
One per person: duplicates will not stack.
While supplies last: the offer "may be withdrawn at any time."
The exact end date is not published. The official wording is "while supplies last / may be withdrawn at any time," so treat the program as rolling and check the live page. Full legal wording lives in the terms and conditions.
A sample program can pause without warning. Because the terms explicitly say the offer "may be withdrawn at any time," submitting early costs nothing and beats waiting for a deadline that may never appear.
Frequently Asked Questions
Is the DefenAge BioSerum sample really free, or is it a subscription trap?
It is a no-purchase sampling offer, not a subscription. The official terms state "No Purchase Necessary" and that the 0.13 fl oz 8-in-1 BioSerum trial ships to you for free. No promo code is involved, and the request form only asks for name, address, and email. If any flow asks for a credit card, you have left the sampling page.
Check the live offer on the official invite page and review the terms yourself before trusting a third-party summary.
How much is the 0.13 fl oz trial actually worth?
DefenAge's full-size 1.0 fl oz BioSerum retails for about $198. Scaled down, a 0.13 fl oz tube carries an equivalent retail value of roughly $25.7 ($198 × 0.13). That is about $6.69 per mL at full-size pricing, since one fluid ounce is roughly 29.57 mL.
As a free trial of a prestige anti-aging serum, that is a meaningful sample — most luxury brands never mail anything near that value. Confirm the current full-size price on DefenAge's homepage before quoting it elsewhere.
Can I request the sample twice or split it with my household?
No. The terms limit the offer to "one offer per person," and the program runs invite-only. Submitting multiple forms from the same address, email, or household is unlikely to produce a second tube, and it risks having your request rejected entirely. Treat one request per eligible adult.
If another household member also qualifies, each person should submit their own separate request through the same official invite page, within the stated rules.
Do I need a promo code to get the free BioSerum?
No promo code exists. This offer is gated by an invitation link instead: you must submit through the official VIP page rather than entering a code at the DefenAge store. Be wary of any site advertising a "DefenAge coupon" for this sample — the brand's terms do not list a code-based promotion for the sampling.
Use only the official VIP BioSerum invite page and verify the terms and conditions on DefenAge's own domain.
When does this free sample offer end?
There is no fixed end date in the published terms. The offer is described as running "while supplies last," and the brand notes it "may be withdrawn at any time." That means it could disappear between one day and the next, without a formal closing notice.
The practical move is to submit your sample request promptly rather than waiting for a deadline that may never come. Always check the live invite page for the most current status as displayed officially.
Will I receive marketing emails after submitting?
The sample request form asks for an email address, which means DefenAge has a channel to reach you. The published terms do not spell out the exact mailing cadence, so treat opt-in wording as it appears on the live form. If you prefer not to hear from the brand beyond shipping updates, look for opt-out choices shown at submission.
The brand's data handling is described in its privacy policy; marketing frequency itself is "as displayed officially."

About DefenAge
DefenAge is a clinical anti-aging skincare brand selling direct to consumers through defenage.com. Its flagship product is the 8-in-1 BioSerum, a multi-tasking serum positioned in the luxury clinical range, where the full-size 1.0 fl oz bottle retails for about $198.
The U.S. brand launched in 2014 and built its line around defensin-based peptide technology, marketed toward skin renewal rather than surface correction. It is distributed through dermatology offices, medical spas, and its own direct-to-consumer site — the same channels used by other clinical skincare lines.
The brand runs its sampling program through invitation-style VIP pages rather than public storefront deals. That structure keeps free trials aimed at first-time buyers evaluating a high-ticket skincare routine.
Community feedback, not official data: in reader and forum discussions, DefenAge users commonly describe the BioSerum as lightweight and fast-absorbing, with results that vary across skin types. Treat those reports as anecdotal — try the free 0.13 fl oz trial on your own skin before judging. The offer follows the rules in the terms and conditions.
