The Supplement Stopped. The Effect Didn't.
A Swiss ceramide trial followed 72 women for 56 days, then took the capsules away and watched for 56 more. What happened next is why this formula exists.
Most beauty supplements have a simple problem: the day you stop, it stops.
That's not a scandal, it's just how consumables work. Your serum works while it's on your face. A filler dissolves on a schedule. Collagen, if it worked, which 23 trials this year suggest it doesn't, would stop working the day the tub ran out.
So when a 2024 trial reported that its effect was still measurable eight weeks after the last capsule, that's worth stopping on. Because it implies something different happened. Not a cosmetic sitting on a surface. Something structural, rebuilt, that stayed rebuilt.
Here's the whole thing, including the parts that are inconvenient for us.
What was actually measured
Kern C, et al. Journal of Cosmetic Dermatology, 2024;23:1320–1330. DOI: 10.1111/jocd.16130.
That's the reference. We're leading with it because everything below depends on it, and because you should check it rather than take our word.
Design: Double-blind, randomised, placebo-controlled, parallel-group. 72 women. 56 days of supplementation, then 56 days of follow-up on nothing.
Measured with instruments, not opinions:
- Corneometer CM 825, skin hydration
- Tewameter TM 300, transepidermal water loss (how fast your barrier leaks)
- Cutometer MPA 580, elasticity
Nobody was asked whether their skin felt nicer. Machines took readings against a placebo group.
Results at Day 56:
| vs placebo | ||
|---|---|---|
| Skin moisturisation | +19% | p < 0.001 |
| Skin elasticity | +18% | p < 0.001 |
| Skin roughness / smoothness | Significant improvement | p < 0.001 |
First significant separation from placebo: Day 14.
And at Day 112, 56 days after the last capsule, the improvement was still there.
A second trial (n=64, women 45–60) tracked crow's feet on the Lemperle scale and found a significant reduction vs placebo at Week 8, a full one-grade improvement.
Why the dose is the whole story
Here's the industry's standard move, and once you see it you'll see it on every shelf.
Put a famous ingredient on the label. Include a fraction of the dose that was actually studied. It's legal. It's accurate. It does nothing.
You've been buying molecules at homeopathic quantities with excellent typography. This is why you've taken supplements for months and felt nothing, not because the ingredient was fake, but because the amount was.
SOOID contains 70.65 mg of Ceramosides® per day. The Kern trial's arm was 70 mg WPLC-Oil.
That's not a coincidence and it's not marketing. The dose is the trial's dose. That's the entire design brief, every other decision in this formula was downstream of "match the published protocol or don't bother."
Check the label. Then check the paper. That's the whole pitch.
The mechanism, in plain language
Ceramides are the lipid mortar between your skin cells. They hold water in. That's not a metaphor, it's the literal architecture of the stratum corneum: cells as bricks, ceramides as mortar.
After 30, production declines. Through perimenopause, because ceramide synthesis is oestrogen-dependent, it collapses.
When the mortar thins: water escapes, light stops reflecting evenly off the surface (which is what "dull" physically is), the barrier lets irritants in, and everything you apply on top starts absorbing onto a compromised surface. Which is why the cream that always worked, stopped.
A topical ceramide sits on top of the shortage. It doesn't refill it.
Ceramosides® is a wheat polar lipid complex, glucosylceramides plus a digalactosyldiacylglycerol fraction. Swallowed, absorbed in the small intestine, partially cleaved to ceramides by an enzyme called glucocerebrosidase, then carried by the bloodstream to the skin, where it refills the pool from within.
That's the published pathway. Not "supports radiance from within."
What's in it, and why each dose
| Ingredient | SOOID/day | The trial it's matched to |
|---|---|---|
| Ceramosides® | 70.65 mg | Kern 2024, 70 mg arm. Matched |
| Astaxanthin (H. pluvialis) | 4 mg | Ito 2018, n=23, 10 wks, 4 mg exactly. Matched |
| Lutein | 10 mg | Juturu 2016, n=46, 12 wks, 10 mg. Matched |
| Zeaxanthin | 2.1 mg | Juturu 2016, 2 mg isomers. Matched |
| Biotin | 450 mcg | EFSA threshold: 7.5 mcg. Well over |
| Vitamin A | 120 mcg | EFSA threshold met |
Ceramosides®, refills the barrier lipid. The hero by mass and by evidence.
Astaxanthin, a carotenoid from algae that spans the entire cell membrane, quenching free radicals from both sides. At 4 mg over 10 weeks, Ito 2018 found increased UV resistance and reduced UV-induced moisture loss. Note: the wrinkle-protection data for astaxanthin is at 6–12 mg, not 4. We're not claiming it. It supports skin against daily environmental load, that's what 4 mg was shown to do.
Lutein + Zeaxanthin, deposit in the skin and act as an internal filter against UV and blue light. Juturu 2016: increased UV resistance (p<0.0001), improved elastic recovery (p<0.05), and, the interesting one, fine lines got worse in the placebo group and didn't in the supplement group.
Biotin, "contributes to the maintenance of normal hair and skin" (EFSA-authorised). Foundation, not hero. There's no good trial showing biotin improves skin in people who aren't deficient, and we're not going to pretend otherwise.
Vitamin A, "contributes to the maintenance of normal skin" (EFSA-authorised). The internal signal for cell renewal.
No collagen. Deliberately. The formula targets the causes of collagen loss rather than adding raw material to a pool that's draining.
The part where we argue against ourselves
You should be suspicious of this page. Here are the three things we'd attack if we were you.
1. "Seppic funds the Ceramosides trials, and Seppic makes Ceramosides."
True. Real conflict. Don't let us slide past it.
But look at what this year's 23-trial collagen meta-analysis actually punished. Not funding, design. Unblinded, uncontrolled, self-reported, small. Kern is double-blind, placebo-controlled, instrument-measured, published, indexed. It's the tier those studies kept failing. Judge the method, not the letterhead, and apply that standard to us as consistently as you'd apply it to collagen.
2. "+19% and +18% are averages against a placebo group. Not a promise to you."
Correct. A trial measures a mean effect across 72 women. It does not guarantee your face. Anyone converting a trial average into a personal promise is lying to you, and we're not going to.
3. "You have no customer reviews."
Also correct. SOOID has effectively no purchase history. We don't have thousands of reviews. We have a placebo-controlled trial.
For most of this category it's the reverse, thousands of glowing reviews and 23 trials that just came back empty. You've now seen how much those reviews were worth. We'd rather be the other way round.
What it costs, against what you're already spending
Not a discount pitch. Just the arithmetic.
| Per year | What it does | |
|---|---|---|
| Botox / fillers | €900–4,000+ | Relaxes what moves, fills what's hollow. Reversible on a schedule |
| Laser / Morpheus8 / Ultherapy | €1,500–4,000+ | Real results, real downtime, real needles |
| Premium skincare shelf | €800–2,400 | The surface. Genuinely well |
| Collagen powder | €300–600 | 23 trials, no significant benefit |
| SOOID | [LOCK THE OFFER] | The barrier lipid, at the trial's dose |
Clinic procedures work. They reach the deep layer, that's exactly why they cost what they cost, and why they involve needles. We're not pretending a chocolate is Botox.
But nothing on that list refills a ceramide shortage from the inside. That's a different job, and it's the only one this does.
What the timeline actually looks like
From the trials, the real measured points, marked. The rest is interpolation between them, and we've said which is which because you'd find out anyway.
| When | What was measured | Source |
|---|---|---|
| Day 14 | First significant hydration + elasticity separation vs placebo. TEWL down in the menopausal subgroup (n=31) | Measured, Kern 2024 |
| Week 4 | Effects continue building | Interpolated, not a trial timepoint |
| Day 56 / Week 8 | +19% hydration, +18% elasticity, p<0.001. Crow's-feet score down one grade (n=64) | Measured, Kern 2024 + extended |
| Day 112 | Improvement still present, 56 days after the last capsule | Measured, Kern 2024 |
If you want a supplement that promises something at Day 3, this isn't it, and the thing promising it is lying, nothing rebuilds a lipid barrier in 72 hours.
Why you haven't heard of it
No conspiracy. Four boring reasons:
- It's new. Ceramosides is a recent ingredient and the key trial published in 2024.
- It's Swiss and small-batch. SOOID makes a chocolate capsule in Switzerland. That's a real constraint on volume, not a scarcity tactic.
- Ceramides have no marketing budget. Collagen had a decade and nine figures of spend. Ceramides had a paper.
- The dose costs money. Matching the trial rather than sprinkling the label is most of the unit cost, and it's why this isn't €19.
That's it. Nobody's suppressing anything. It's just early.
The format, which sounds like a gimmick and isn't
Three chocolate capsules a day. No water, no pill, no mixing, no powdered-milk aftertaste. About 1.5 kcal a day total.
Here's why it's in the formula and not just on the box: this category's real failure isn't efficacy at week 8. It's that almost nobody reaches week 8. The first significant effect is Day 14; the wrinkle data is Week 8. Every supplement you've ever abandoned, you abandoned around week three because it was one more capsule to resent.
Nobody forgets to eat a chocolate. Compliance is the active ingredient, and it's the one thing every trial quietly assumes and no product design accounts for.

FAQ
How long until I see something?
Day 14 for the first measured change vs placebo. Week 8 for wrinkle depth. Not sooner.
Is this collagen?
No. There's no collagen in it. That's deliberate.
Can I take it with my routine / HRT / other supplements?
It's a food supplement. No known interactions. If you're on medication, ask your doctor, not a landing page.
Is it vegetarian?
Contains milk. Not vegan.
Gluten free?
Not confirmed. Ceramosides is wheat-derived. We don't have the certificate back. If you're coeliac, wait until we do.
What if it doesn't work?
[GUARANTEE]. And read the trial first, the DOI's at the top. We'd rather you check than take our word.
Contains: milk, wheat, soy, hazelnut, almond, macadamia. It's a real chocolate. If you react to any of those, this is not for you.
