I was nervous, but the results speak for themselves
I wanted something effective but I'd been let down by cheap devices before. The gentle tingling reassured me it was working — not painful at all. After 8 weeks, my neck looks tighter and my jawline is noticeably firmer. My colleagues have asked what I've been doing differently. Best £89 I've spent on skincare.
Why YOOJ Works Where Other Systems Fail
Precision-Flow Technology Delivers Real, Lasting Collagen Stimulation
Product Details
The Problem
You're caught between two failing options. Clinic treatments deliver results — but at £250+ per session, you can't sustain them long-term. Traditional serums and creams sit on the surface, absorbing just 3-7% of active ingredients. Your skin shows deepening lines, sagging around the jawline and neck, and visible loss of firmness — but you've given up because nothing affordable actually works.
The Solution
YOOJ bridges that gap with controlled micro-infusion technology. The 0.5mm depth creates microscopic channels that allow barrier-safe serum to reach the dermis — where collagen production happens — without the trauma, cost, or recovery time of clinic treatments. You get 70-80% of professional results at home, for under £10 per treatment.
Specifications
✔ Needle depth: 0.5mm (clinically optimal for at-home collagen stimulation)
✔ Treatment area: Face, neck, jawline, décolletage
✔ Cartridge volume: 2ml per cartridge (sufficient for full-face + neck treatment)
✔ Serum formulation: Peptide-Ceramide-Hyaluronic Acid complex (fragrance-free, barrier-safe)
✔ Device dimensions: 12cm x 4cm x 3cm
✔ Weight: 85g (lightweight, ergonomic grip)
✔ Cartridge compatibility: YOOJ proprietary click-and-twist system
The Science: How YOOJ Micro-Infusion Works
The Mechanism:
The YOOJ system uses a 0.5mm microneedle stamp combined with pre-loaded, barrier-safe serum cartridges. When pressed gently against cleansed skin, the device creates thousands of microscopic channels in the epidermis. These channels allow the Peptide-Ceramide-HA serum to penetrate deeply into the dermis, triggering your skin's natural wound-healing response — which stimulates fresh collagen and elastin production over 8-12 weeks.
Why 0.5mm is Superior to Clinic Depths:
Less trauma, faster recovery — Clinic treatments use 2.0mm depth, causing redness and swelling for 3-5 days. YOOJ's 0.5mm depth stimulates collagen effectively whilst keeping recovery time under an hour.
Safer for delicate areas — The controlled shallow depth is ideal for your neck and décolletage, areas that show ageing first but cannot tolerate aggressive clinic treatments.
Sustainable routine — You can treat every 2 weeks comfortably, maintaining consistent collagen production instead of spacing out expensive clinic visits over months.
Unique Advantages:
✔ Pre-loaded cartridges eliminate contamination risk — No messy vials, no guessing dosage
✔ Barrier-safe formulation — Peptides, ceramides, and HA support your skin barrier instead of irritating opened micro-channels
✔ Ergonomic stamp design — Even pressure distribution across treatment area
✔ CE-certified medical-grade materials — Sterile, single-use cartridges
✔ Quiet, discreet use — No loud motor or vibration like derma-rollers
Why Women Over 40 Trust YOOJ
Real Results Backed by 10,000+ British Users
Traditional at-home devices either break after three uses or deliver zero visible improvement. Clinics work — but cost £250+ per session, making long-term maintenance impossible. YOOJ finally solves this with a system that's affordable enough to use consistently whilst delivering genuine, measurable transformation.
Evidence & Results:
✔ 70-80% of professional results at under £10 per treatment
✔ 4.7-star rating from over 10,000 verified British customers
✔ Visible tightening of neck, jawline, and nasolabial folds within 8-12 weeks
Expert Insight:
"The 0.5mm depth sits in the optimal range for stimulating collagen production without excessive trauma. Combined with barrier-safe serum delivery, this approach offers a genuine middle ground between ineffective topical products and invasive clinic procedures."
— Dr. Sarah Collins, Aesthetic Dermatology Specialist
How to Use YOOJ
Quick Start (3 Steps):
Step 1: Cleanse your face and neck thoroughly. Pat dry.
Step 2: Attach a fresh serum cartridge to the YOOJ device using the click-and-twist mechanism. You'll hear a satisfying click when it's locked in place.
Step 3: Gently stamp the device across your treatment area in a grid pattern — forehead, cheeks, jawline, neck. Apply light, even pressure. You'll feel a gentle warm tingling sensation as the serum penetrates.
Step 4: Allow serum to absorb for 2-3 minutes. Follow with your usual moisturiser if desired.
Recommended Frequency:
Use once every 2 weeks for optimal collagen stimulation. This gives your skin time to complete its natural healing and rebuilding cycle.
Results Timeline:
Day 1: Immediate glow and plumpness from enhanced serum absorption
Week 1-4: Skin texture feels smoother, fine lines appear softened
Week 8-12: Visible tightening around neck and jawline, reduction in deep lines, improved firmness
✔ Pro Tips:
✔ Treat in the evening so any mild redness fades overnight
✔ Use on neck and décolletage — these areas show ageing first but respond beautifully to 0.5mm depth
✔ Store cartridges in a cool, dry place to maintain serum potency

Frequently Asked Questions
About the Product
1. What makes YOOJ different from derma-rollers or other at-home devices?
YOOJ uses a stamp mechanism instead of rolling, ensuring even pressure and controlled 0.5mm depth across your entire treatment area. The pre-loaded cartridges eliminate the mess and contamination risk of traditional vials — just click, twist, and treat.
2. Will this work on mature skin (50+)?
Absolutely. The collagen-stimulation mechanism works at any age. In fact, women over 50 often see the most dramatic improvement because their skin responds powerfully to consistent, gentle stimulation after years of ineffective topical products.
3. Can I use my own serums with the device?
We strongly recommend using only YOOJ cartridges. Our Peptide-Ceramide-HA formula is specifically designed to be barrier-safe for opened micro-channels. Using random serums risks irritation from fragrances, harsh preservatives, or incompatible pH levels.
Shipping & Delivery
1. How long until my order arrives?
We dispatch within 24 hours (Monday–Friday). Standard UK delivery takes 2-4 working days. You'll receive tracking details via email as soon as your order ships.
2. Do you ship to Northern Ireland and Scottish Highlands?
Yes, free UK shipping covers all regions including Northern Ireland, Scottish Highlands, and offshore islands. Delivery may take an additional 1-2 days for remote areas.
3. Is the packaging discreet?
Yes. Your YOOJ system arrives in plain, unmarked packaging with no external branding.
Returns & Guarantee
1. What does the 90-day guarantee actually cover?
We cover the full collagen cycle — 8 to 12 weeks — so you have time to see real, lasting results before deciding. If you're not satisfied for any reason within 90 days, simply return your device (even if used) for a full refund. No questions asked.
2. What if I don't see results?
Collagen stimulation takes time. Most women see visible tightening around week 8-12. If you haven't noticed improvement after consistent use (once every 2 weeks for 12 weeks), contact our support team — we'll either extend your trial period or process your refund immediately.
3. Do I need to return the used cartridges too?
No, only the device itself. You can keep or dispose of any used cartridges.

Product Reviews
H
Finally something that actually works on my neck
id given up on my neck honestly, creams did nothing and i couldnt justify £250 sessions every month. This has genuinley tightened the area under my chin and my jawline looks more defined after about 9 weeks of using it every fortnight. The tingling is noticable but not painful - more like confirmation its doing something. I use it Sunday evenings whilst watching telly and any redness is gone by morning. Worth every penny and ive already ordered my second pack of cartridges.
M
Sceptical at first but genuinely impressed
I'm 52 and I've wasted money on SO many devices that broke or did absolutely nothing... I was very sceptical but the 90 day guarentee convinced me to try. The cartridge system is brilliant - no mess, no guessing!! I've been using it for 10 weeks now and my nasolabial folds (the lines from nose to mouth) are visibly softer and my skin texture is smoother. My daughter asked what I'd been doing differently which made my week 😊 Only slight downside is I wish the cartridges lasted two treatments instead of one, but I suppose that keeps everything sterile.
L
Good results but cartridges run out quickly
The device itself is excelent and I'm seeing improvement in my forhead lines and around my mouth after 8 wks. The serum feels lovely and the tingling lets you know it's working. My only complaint is the cartridges - there single use so if your treating face and neck like I am you go through them fast. Works out to about £10-12 per session which is still far cheaper than clinics but I'd love a slightly larger cartridge option
S
Transformed my morning routine
quick effective and fits into my actual life!! takes me 5 mins max and i do it saturday mornings after cleansing. no more booking appointments or sitting in waiting rooms. the gentle tingling is oddly satisfying and my skin looks plumper almost immediatley, though the real firming took about 10 weeks to properly show
P
Better than my £280 clinic sessions
I used to go to a clinic in Harley Street for microneedling but couldn't keep up with the cost or the 4 day recovery where my face looked like I'd been sunburnt. This gives me very similar results - my skin is tighter, my pores look smaller, and the deep line between my brows has softened significantly. The 0.5mm depth is perfect becuase I'm not stuck indoors recovering. I treat every two weeks religiously and I'm on month 3 now with visible improvement. Genuinely life changing for my confidence.
C
Works well but took longer than expected
Im happy with my purchase but just be aware the dramatic results dont happen overnight... I started seeing subtle changes around week 6-7 but the real "wow" moment was closer to 11 weeks. My neck definately looks tighter and my jawline is more defined. Knocked off one star because I wish the instructions included a video - I had to watch a youtube tutorial to make sure I was doing it correctly
J
My colleagues keep asking what I've done
I work in an office and THREE separate people have asked if I've "had work done" which is the best compliment!! 😄 My skin looks fresher and the sagging under my chin thats bothered me for years is noticably improved. The cartridge system is so clever - no faffing about with bottles. I do it sunday nights and monday mornings i look glowy. Shipping was fast too arrived in two days
A
Finally addressing my décolletage
Nobody talks about chest wrinkles but they age you terribly!! I've been using this on my face neck and décolletage for 12 weeks and the crepey texture on my chest has improved dramatically. The serum absorbs beautifully and doesnt irritate even on that delicate area. So glad I found something that actualy works on these areas that clinics charge extra to treat.
E
Excellent device, packaging could be better
The product itself is fantastic - I'm 8 weeks in and my skin texture is noticeably smoother and my jowls are less prominant. The tingling is mild and kind of pleasant. Only reason for 4 stars is the outer packaging arrived a bit dented (though the device inside was fine) and I think the protective case could be slightly sturdier. Minor complaints really the results speak for themselves.
K
Best investment in my skincare routine
Im 48 and this has replaced about 4 products in my bathroom cabinet!! The way the serum actually penetrates instead of sitting on top of my skin is game changing. My forehead looks smoother and the lines around my mouth are much less deep after 10 weeks. Its become my sunday evening ritual and I genuinely look forward to it. Cant recommend enough
D
Bought one for my sister too
Worked so well on my neck and jawline that I bought one for my older sister for her birthday, shes thrilled with it. Were both seeing proper results - tighter skin fewer deep lines and that annoying sagging under the chin improving week by week. The fact its affordable enough to maintain long term is what makes it actually sustainable unlike clinic appointments
S
Great results, wish cartridges were cheaper
The device is excellent and I'm genuinely seeing my skin firm up after 9 weeks of consistant use. My only grumble is the ongoing cost of cartridges - theyre not cheap and you do need to reorder regularly. That said its still far more affordable than professional treatments and the convenience of doing it at home whilst having my morning coffee is priceless. Would buy again
J
No more hiding my neck in scarves
i used to wear scarves and high neck tops constantly to hide the crepey skin on my neck 😞 after 11 weeks with YOOJ the texture has improved so much i actually wore a v-neck jumper last week without thinking twice!! the device is so easy to use and the serum doesnt irritate my sensitive skin at all. genuinely life changing
C
Works brilliantly but requires patience
If your expecting overnight miracles this isnt for you... but if your willing to commit to the routine (once every 2 weeks) you'll see real results. I'm at week 12 and my skin is visibly tighter around my jawline and the marionette lines have softened considerably. Lost one star only because it took the full 12 weeks to see the transformation I was hoping for - but it did happen so I'm happy overall.
B
So much better than the roller I tried before
I tried a derma roller last year and it was a disaster - uneven pressure hurt like mad and I couldn't tell if I was using it correctly 😣 This stamp system is completley different. Even pressure every time, the cartridges mean no mess and the 0.5mm depth is comfortable. My skin looks healthier and plumper after 8 weeks and I've had zero issues with irritation
D
My skin hasn't looked this good in years
I'm 56 and honestly thought i'd missed the boat on improving my skin without going under the knife. This has proved me completley wrong!!! The transformation in my neck and face after 12 weeks is remarkable - firmer smoother and the deep lines around my nose and mouth are significantly softer. I stand by mirrors now instead of avoiding them. The gentle tingling during treatment is reasuring rather than scary and I love that I can do it in my own bathroom. Absolute game changer for my confidence and worth every single penny.
