You've already bought three that didn't work. With this one, you'll know in thirty minutes.
It stings for five minutes, and you can see the tightening effect within half an hour. It's the only product in your bathroom that you can judge right from the first night.

100 ml, enough for 3 to 4 weeks when used morning and night · Shipped from France within 2 to 4 days
The100-ml bottlelasts three to four weeks.Morning and evening. Apply to clean skin before using other products.Five minutes. It stings for a bit, then it subsides.
Here's what we'll tell you right away: the tightening effect wears off overnight. The long-lasting results, however, appear after a three-week treatment regimen. You'll know this before you pay, not after.
You can't really tell if most skincare products are working. You apply them, wait three weeks, still have no idea if anything's happening, and the bottle ends up in a drawer.
You can feel this one right away. The fruit acids work on the surface—it tingles for a few minutes, your skin feels slightly tight, and your pores look tighter before you’ve even left the bathroom.
What the title promises
What's Happening, Minute by Minute
Minute 0:You apply it. It gets warm and tingles. That's the fruit acids—it's a bit of a surprise the first time.
Minute 5: Thesensation subsides. This is when the skin feels tight.
Minute 30: Youcan apply makeup over it. Elo writes, “Smoother skin, tighter pores—an immediate effect,” and Samira says, “It looks like there’s a filter on the photos.”
The next day: Nothingspectacular—the surface effect has faded. It renews itself with each application, and it’s the three- to four-week treatment that makes the results last.

What's Changing
They thought exactly the same way you do.
What you tell yourself when you get here
Another Facebook ad—it won't work on me.
I've already tried three creams, and none of them worked.
Before-and-after photos are always retouched.
At my age, nothing really fazes me anymore.
What they sent us next
These photos were sent to us by real customers and their loved ones from their phones. They haven't been edited, and we didn't commission a single one.
A few seconds later, the face is split in two. On the right: the eyelid is lifted, and the cheekbones and facial contours are visibly more lifted.
The outline of the mouth: The lines around the lips and the nasolabial fold—top left, bottom right.
Sent by a subscriber. She had purchased the normal skin version. Photos received as is.
Kathie, 43. Shehad two deep wrinkles around her mouth after losing weight. She replied to one of the brand’s Instagram Stories, and her message is reproduced in full below the photo. Her takeaway: “I only have one line when I apply it.” This message is not a Judge.me review: it’s visible in the image.
Immediately after application, you'll notice a tightening effect. It fades over the course of a few hours, and with regular use, the skin's condition improves over the long term. Results vary depending on skin type and how often the product is used.
One was sent to us by a customer; the other four come from the brand's social media accounts, including the watermark. The bottle shown isn't always the one in the photo: it's the old packaging, but it's the same serum. We didn't edit the images; we just removed the black bars.
She applied it to only one side. The other half of her face serves as a control.A customer shows the underside of her eye, at point-blank range.A man uses it, too, and says so on camera.The entire process, from the bottle to the face."Tired, dull skin, dark circles," and then the same face afterward.

The first one shows results on the same day: this is the tightening effect, and it fades overnight. The long-lasting results, however, appear after a three-week treatment regimen. Results vary depending on skin type and consistency of use.
The mechanism
Why Things Are Heating Up
25 seconds, unedited.
The serum is formulated with fruit acids —alpha hydroxy acids. They work on the skin's surface, and that's what you feel. The sensation builds, lasts a few minutes, subsides, and becomes less intense with each application.
No needle. Nothing pierces the skin.
Fruit acidsRefine skin texture and restore radiance. They’re the ones that give you that tingling sensation.
Hyaluronic acidRetains water in the skin, making it appear plump.
Argan oilNourishes and softens.
Rose WaterSoothes the skin after acid treatment.
FenugreekSoftens the skin and gives it a plumper appearance.

The reviews that haven't been removed
Six out of 58 customers gave 3 stars or fewer. Two did not write a review. Here are the other four, in their entirety, unedited, along with what we did with them.
Hanane EL MOUTIQUI★★☆☆☆
"I had already tried the booster, which I loved, but the 'Max' booster stings so much that my face turns red for a while, and I don't think it has any smoothing effect. Plus, the container is definitely not practical because the pump gets stuck and I can't get the product out properly."
Verified Review · Skin Booster Max Serum - Normal Skin 100 ml
What we did about it: She had bought the version for normal skin, which was too harsh for her reactive skin. The version for sensitive skin is the same price; you can find it in the selection at the top of the page.
Juliette Luciani★★★☆☆
"It's great, but my skin has a hard time tolerating it... it feels like a burning sensation... it stings my face too much... I should have gotten the version for sensitive skin..."
Verified Review · Skin Booster Max Serum - Normal Skin 100 ml
What we did with it: It provides the answer itself, which is why the choice between the two versions is displayed before the first button—not hidden at the bottom.
Habiba Ferah★★★☆☆
"Good products, but expensive because, even with promo codes, the shipping costs are high."
Verified Review · Skin Booster Max Serum - Normal Skin 100 ml
What we did: The code on this page removes the entire shipping charge, not a percentage of the product price. That's exactly what she asked for.
Sweety Melchior★☆☆☆☆
"My package arrived damaged, and as of today, I haven't received a replacement—I'm still waiting."
Verified Review · Skin Booster Max Serum - Normal Skin 100 ml
What we've done about it: Nothing, so far, and we're not deleting it. It's the only one-star review out of 58, and it's not about the serum—it's about us.

Habiba Belfar★★★★★
“I can’t live without it anymore! I bought it using Maëva Ghennam’s promo code. At first, I wasn’t sold on it because no one mentioned that it stings, so I didn’t know if that was normal or not—but now they do mention it. I find the cream effective; it gives your skin a boost, reduces puffiness, and plumps it up. I’m very satisfied. I use the normal skin formula, but if you have delicate or sensitive skin, I recommend the sensitive skin version because it stings quite a bit. The customer service is wonderful—I had an issue with my package, and they resolved the situation quickly, efficiently, and kindly. A big thank you!!!!”
Verified Review · Skin Booster Max Serum - Normal Skin 100 ml
Here's why we're including this one right after: both customers are talking about the same damaged package. One is still waiting, while the other's issue was resolved “quickly, efficiently, and courteously.” We're giving you both—draw your own conclusions.

The gesture
Where to apply it
1Under the eyes—where dark circles form. This is the area clients mention most often.
2The cheekbones: Move upward toward the temples, never downward.
3The facial contour: Fromthe jawline to the ear, on both sides.
Apply in circular motions to clean skin after washing your hands. Use morning and evening for 3 to 4 weeks, then every other day to maintain results.
The gesture, in close-up
Bare skin, unfiltered, visible pores.
564 refunds out of 54,630 orders. That's our guarantee.
We don't accept returns on opened bottles: this is a cosmetic product, and once it's been opened, it can't be restocked—and we're not legally required to do so. The websites that promise you otherwise know this just as well as we do, and they'll cite this very rule the day you file a complaint. We're telling you this before you pay. Here's what we'll give you instead.
Unopened—you have 14 days
This is your legal right of withdrawal, and it applies in full as long as the bottle is unopened. If you return it, you'll get a refund.
Damaged or lost package, or it's not what you ordered
That's our problem, not yours. Please email contact@girlspowers.com with your order number.
Opened and half used, no
We're not going to lead you on just to make money off you tonight and then let you down in three weeks.
99,35 %
This is the percentage of orders that have never been refunded—not even partially—since the site launched: 54,066 out of 54,630. A page that promises you a refund will never give you that number. We’re not just throwing you a lifeline; we’re giving you the one number that actually means something to you.
I've already tried a lot of creams without any results. Why would this one be any different?
Because you can feel it. A traditional cream just sits on your skin: you don’t feel anything, and often you don’t see anything. Here, the fruit acids work on the surface—it tingles—and you can see the tightening effect within half an hour. That’s not a guarantee that it’ll work for you, but it’s a difference you can see the very first night.
How long does it take?
A few minutes. Nadia, verified review: “It stings for only 5 minutes because I used the one for normal skin, but it’s not bothersome.” Corinne, verified review: “It stings and burns at first, but after a week… you get used to it… very effective.” The sensation lessens with each application.
My skin gets red easily—can I use this?
Go for the sensitive skin version—it's the same price. That's exactly the advice given by our two customers who rated it 2 and 3 stars, and by Habiba Belfar in her 5-star review.
What if it doesn't work for me?
Once a bottle is opened, it can't be returned—as we stated plainly earlier. What we can give you instead are the raw numbers: out of 58 customers, 43 gave five stars, 9 gave four, and the other six reviews are posted in full above. Out of 54,630 orders, 352 were fully refunded and 212 were partially refunded.
Is that an injection?
No. There are no needles—nothing pierces the skin. It’s a serum that you apply and massage in. On the photo of the bottle, the label says “injection-like effects”: it refers to the desired visual effect, not a medical procedure. We’d rather tell you this than let you figure it out on your own.
When will I see the first results?
The tightening effect is visible within half an hour and fades over the course of several hours. For long-lasting results, follow the treatment regimen for 3 to 4 weeks, then use it every other day.
Ordering, Bottle Life, Shipping, Payment
How to use: Apply the serum first, morning and night, on clean skin. As part of your routine, apply the creams on top once the serum has been absorbed. Duration: 100 ml, which lasts 3 to 4 weeks when used morning and night, then much longer for maintenance. Shipping: Free in mainland France and Belgium; the code is already included in the buttons on this page, so you don’t need to enter anything. Without a code, the store offers free shipping on orders of €99 or more. Shipped from France; delivery takes 2 to 4 days.
What he does, in a nutshell
The skin looks smoother and pores are less visible starting with the very first application. You can see it in the photos above and in the 58 reviews. Maryde is 72 years old and doesn't want anyone to know it. Florence has been nicknamed Benjamin Button. Samira says her photos look like they have a filter on them.
It won't erase ten years overnight—no serum can do that. What it does, it does tonight.
You apply it, it tingles for five minutes, and you look at your face half an hour later. That's all we're asking you to do.
This is the only thing I put on my face, and I can assure you that this product delivers on its promises when I wear makeup—I look well-rested, and people don't guess my age at all—it's incredible.
Hello Maya, thank you for sharing your experience. We’re sorry that the Fontaine de Jouvence Duo didn’t deliver the results you were hoping for and that it’s making your skin too oily. Everyone’s skin reacts differently; please feel free to contact us so we can recommend a routine that’s better suited to you—for example, alternating between Lift No. 1 as your day cream and Botox No. 2 as your night cream.
Best regards
