Your questions, answered
Does it hurt?
No. You'll feel a light tingle for about 30 seconds: that's the micro-spicules opening the way for PDRN. Most people find it weird at first, then reassuring, because you can actually feel it working.
I've tried PDRN serums before. Nothing happened.
That's not your fault. PDRN is a big molecule, so most serums just sit on the surface. That's why clinics inject it. Oursin's micro-spicules open temporary micro-channels so PDRN reaches where it works.
Is it like Botox or injections?
No. No needle, no frozen face, no "done" look. It's a cosmetic serum inspired by clinic PDRN treatments. Your face still moves and still looks like you, just more rested. Results are not equal to a procedure.
Will my skin go red?
Some people get a light pink flush that fades within a few hours. Use it in the evening and start 2 nights a week, then every other night once your skin is used to it.
When will I see results?
Smoother skin after the first few uses. Texture and glow around 4 weeks. Firmness, fine lines and marks 8 to 12 weeks, which is why most people start with the 12-Week Protocol.
I have sensitive or breakout-prone skin.
Patch test 24 hours before your first use and start slowly. Don't apply on active breakouts, broken skin or sunburn. Pregnant or have a skin condition? Ask your doctor first.
What if it doesn't work for me?
You're covered. 60 days to see visible results, or your money back. One email, no awkward questions.
Real results
Real women, real skin.
"I actually feel confident without foundation now."
My biggest frustration was how uneven and tired my skin looked. I wanted something more than another basic serum. My complexion looks brighter, my skin feels softer, and I love how it looks without makeup.
Emily R., 34 Customer
"My skin finally looks like it's had some rest."
I'd tried so many anti-ageing creams, but my fine lines always seemed to stand out. My skin looks smoother, fresher and more radiant. It's become my favourite part of my skincare routine.
Sarah M., 46 Customer
"My skin looks so much fresher."
I was starting to notice that my skin looked tired even after a good night's sleep. I love how hydrated and plump it feels now. My skin looks healthier, and my makeup sits so much better.

The formula
What's inside Oursin.
Four ingredients, one job: reach the layer where skin renews, then help it do what it used to do on its own.
001
002
The messengers
Exosomes
Tiny messengers that tell tired skin cells to wake up and get back to work. The secret to that rested, lit-from-within look, even after a short night.
003
Microneedling in a serum
Micro-Spicules
Natural micro-spicules open tiny, temporary channels so the actives actually get in. That light tingle? It means it's working. No needles, no device.
004
The calming one
Centella Asiatica
A Korean skincare classic that soothes and comforts, so your skin wakes up looking calm and balanced, not irritated.
No needles
No device
No downtime
60-day guarantee
Why nothing worked
It's not your skin. It's where your skincare stops.
That drawer full of lotions and potions? It wasn't you, and it isn't just your age. Your skin's barrier is built to keep things out, including your serums. So most actives, PDRN included, sit on the surface, feel nice for ten minutes, and never reach the layer where skin actually renews.
How Oursin works
Open. Deliver. Renew.
Oursin doesn't sit on top and hope for the best. It's built to get in, so PDRN and exosomes finally reach the layer where your skin renews. No needles, no device, no clinic bill.

Skincare stories
Different Skin. Different Stories.
Texture & pores
Finally something different
I've got a whole drawer of skincare that promised smoother skin. Honestly didn't expect much from this either. The texture is lovely and my skin feels much smoother now. My foundation doesn't seem to cling to every little bump anymore. Really happy with it.
First signs of ageing
Wish I'd found this sooner
Hit 40 and suddenly my skin just wasn't the same. Nothing dramatic, just little changes that bothered me. Been using Oursin for about a month and I'm genuinely pleased. My skin feels firmer and looks fresher. Even my husband noticed something was different, which never happens!
Tired, dull skin
Actually love this
Was getting so fed up with looking knackered all the time, even after a decent night's sleep. Bought this on a whim after seeing it online. My skin looks brighter and feels really soft. Still have my tired mornings obviously, but at least my skin looks a bit more alive!
Firmness
Really impressed
I've tried some ridiculously expensive skincare over the years. Wasn't keen on going down the injectable route, so thought I'd give this a go. It's easy to use and fits into my evening routine. My skin feels more supple and looks a bit firmer. Already ordered another bottle.
Post-acne marks
So glad I tried it
My spots finally settled down last year but I was still dealing with the marks they left behind. I've been using Oursin consistently and my skin looks more even now. I still use concealer on some days, but nowhere near as much. It's been a really nice addition to my routine.

Your Questions, Answered
Each stick contains 8.5g of psyllium husk, a natural fibre that absorbs water and expands into a soft gel in your stomach, so you feel physically full. Chicory inulin helps that fullness last longer and supports your gut as a prebiotic fibre.
Some people feel a little more full or gassy during the first few days while their body adjusts to more fibre. That's normal and usually settles quickly. Start with one stick a day and always drink a full glass of water with it.
Mix one stick with at least 250 ml (8 fl oz) of water, stir and drink straight away, once a day. Best taken 20 to 30 minutes before the meal or time of day your cravings usually hit. Keep at least 2 hours between lommy and any medication.
Psyllium husk (8.5g), chicory inulin (1g), natural lemon flavour, citric acid, steviol glycosides (stevia) and silicon dioxide (anti-caking agent). No stimulants, no caffeine, no added sugar.
Most people feel the physical fullness from the very first stick. Give it 2 to 3 weeks of daily use for it to become part of your routine. Results vary from person to person.
