No amount of skincare can fix a hormonal acne issue.
You’ve tried every cream, acid and antibiotic. This is the one thing that works on the actual cause — 13 probiotic strains, zinc and skin vitamins. In a 30-day study, 90% saw clearer skin.

30-day dermatological study, 20 participants under dermatological supervision. Certificate of Excellence.
You’ve probably thrown thousands at your skin.
Drugstore products. A ten-step routine you dreaded every morning. Facials, lasers, the €80 serums. Then the medical route — tretinoin and its months of purging, antibiotics that worked until the day you stopped, the pill, maybe spironolactone.
Every step promised it would finally settle down. It never did. You’ve tried literally everything, and still — it’s every day, a new spot. Somewhere along the way it stopped being about skin: “I feel like the only adult on the bus with acne.” “My skin is betraying me.” You started to believe the problem was you — your discipline, your diet, that you weren’t doing enough.
You were doing plenty. You were just sold the same idea over and over — that clear skin is something you fix on the outside. So you bought the next cream, the next acid, the next routine. And the breakouts kept their own schedule, arriving like clockwork before every period.
It was never about the outside.
You weren’t doing too little. You were looking in the wrong place.
Hormonal breakouts don’t start on your face. They start in the gut — where 70% of your immune system sits and where the signals that drive inflammation and sebum begin.
A cream can only ever work on the layer you can see. It never reaches the place the breakout actually comes from. That’s why it keeps coming back the moment you stop — and why Radiance Powder takes the opposite route: it works from the inside, on the gut–skin axis, so the cause has somewhere to change.

Here’s what actually changes — and when
13 multi-strain probiotics rebalance the gut. Zinc regulates sebum and hormones. Vitamin C and B-vitamins support the skin. Together they break the breakout cycle from the inside.
70% of your immune system lives in your gut — and that’s where hormonal breakouts are switched on.
For years you treated the surface. But no cream can reach the place a breakout actually starts. As one customer put it: “I didn’t realise the correlation between gut and skin issues.” Calm the gut from the inside, and the skin finally stops fighting back.
Here’s the honest part: this isn’t overnight. In 30 days, 90% saw clearer skin — but the women who go the full 90 days report the real shift: breakouts that stop coming back, skin that stays calm even around their period. You’ve already waited years. We’re only asking for three months.
Nutrients travel from a rebalanced gut to the skin — calming inflammation at the source instead of the surface.
70% of your immune system lives in your gut — the engine behind inflammatory, hormonal breakouts.
Your gut starts rebalancing. Most notice reduced bloating within the first few days.
Fewer new breakouts. Existing spots heal faster. The inside-out shift begins.
90% of study participants saw noticeably clearer skin. Pores appear smaller.
Skin stays calm even around your period. This is the new normal.

The 15 questions we get most
How much does it actually cost per day?
On the 3-month Kur it’s €1.66 a day — less than a single facial, spread across a full cycle.
How does the 90-day money-back guarantee work?
Give it a full cycle. If your skin isn’t clearer, email us within 90 days and we refund you in full — opened jars included. No forms.
Which hormone does it balance?
We don’t claim to know which hormone is off for you — no supplement can. It works on the gut, where 70% of your immune system sits and where hormonal breakouts start. Zinc and B-vitamins support hormonal activity.
What exactly is in it, and how much?
13 probiotic strains, zinc citrate, vitamin C, a B-complex and prebiotic fibre. One scoop is 5g; the exact amount of each is printed on every pack.
How fast will I see something?
In the 30-day study, 90% saw clearer skin. Many customers notice fewer new spots within the first 1–2 weeks. A full cycle is 3 months.
Why three months?
Skin renews in cycles. The study ran 30 days; the biggest changes customers report come over a full 2–3 month cycle. The Kur is sized to match.
I recently came off the pill. Is this for me?
Yes — many customers come to klarskin after stopping birth control, when skin goes into overdrive. It works on the gut and hormonal support.
Is it vegan, and where is it made?
Yes — a vegan formula, made in Germany, no unnecessary fillers.
Can I take it with my medication?
It’s a food supplement. If you take medication or are under treatment, check with your doctor before starting.
I have sensitive skin — could it react?
It’s taken by mouth, not applied to the skin, so it won’t sting or irritate. If you have a diagnosed condition, ask your doctor first.
Do you have reviews outside your own store?
Our 276 reviews are collected via Loox. We’re actively adding more independent, third-party reviews.
How do I take it?
One scoop (5g) stirred into 300ml water, once a day with breakfast. A one-minute habit.
Can I cancel the subscription?
Yes — cancel anytime, no lock-in. One-time plans have no commitment at all.
What about shipping and customs?
Free EU shipping over €100. Any duties for non-EU orders are shown at checkout.
What if it just doesn’t work for me?
Then you pay nothing. The 90-day money-back guarantee covers a full cycle.
