PREMENSTRUAL SKIN SUPPORT

Why your skinbreaks out before your period.

And why nothing you've tried has stopped it — until now. The problem isn't your skincare. It's how your gut processes hormones. Support the gut-hormone-skin connection with one daily powder. 21,000+ women trust klarskin.

THE GUT-HORMONE-SKIN AXIS

Three systems.One recurring problem.

Most dermatologists never mention this. The connection between your gut microbiome, hormone processing, and premenstrual breakouts is real, well-researched, and the reason 27,000+ women stopped chasing topical fixes and started working from within.

01THE HORMONES

Estrogen fluctuates. Every cycle.

In the days before your period, estrogen levels drop sharply while progesterone tries to compensate. This shift is normal and inevitable — but for it to pass without breakouts, your body needs to eliminate the excess hormone efficiently.

What happens if it doesn't:

  • Testosterone becomes relatively dominant → sebaceous glands produce more oil
  • Pores clog faster → hormonal comedones and cysts
  • Inflammation ramps up → the deep, painful jawline spots you can't cover with concealer

SIGNS HORMONES ARE THE TRIGGER

  • Breakouts appear 5-7 days before your period
  • Same area every cycle — usually jaw, chin, cheeks
  • Deep, painful cysts that take weeks to heal
  • Cyclical bloating that arrives with the acne

02THE GUT

Your gut is supposed to clear excess hormones.

Your gut microbiome — specifically the estrobolome — is the primary system that processes and eliminates old estrogen. Healthy microbiome, healthy elimination, no recirculation.

But when the microbiome is imbalanced (stress, antibiotics, low-fibre diet, years of failed acne treatments) it can't do its job. Old estrogen recirculates through your bloodstream instead of leaving your body.

The gut can't clear hormones when:

  • Microbiome is low in Bifidobacterium and Lactobacillus strains
  • Diet is low in fibre and cruciferous vegetables
  • Bowel transit is slow (constipation, bloating)
  • Antibiotics have been taken in the past 12 months

SIGNS YOUR GUT NEEDS SUPPORT

  • Bloating that worsens before your period
  • Irregular bowel movements
  • History of antibiotics or the Pill
  • Food sensitivities alongside skin issues

03THE SKIN

The skin becomes the exit route.

When the gut can't eliminate excess hormones efficiently, the body tries to release them through the next-largest detox organ: your skin.

What you see is a symptom. What's happening underneath is a bottleneck. And every topical treatment you've tried — retinols, antibiotics, spot treatments — works on the visible symptom while the underlying pipeline stays blocked.

Why topical treatments alone don't work:

  • They can't address the hormone recirculation
  • They don't rebuild the microbiome
  • They can weaken the skin barrier, making things worse long-term
  • The next cycle brings the same problem back

SIGNS TOPICALS AREN'T ENOUGH

  • Breakouts return every cycle no matter what you apply
  • Skin gets more reactive with each new product
  • Retinols and antibiotics work briefly, then stop
  • Post-acne marks that never fully fade

WHAT TO EXPECT

The timeline,honestly explained.

This isn't a cream that works overnight. Rebuilding your microbiome and stabilising hormone processing takes cycles. Here's exactly what tends to happen.

  1. Week 1-2

    Microbiome rebuild starts.

    You take one scoop of Radiance Powder each morning. The 13 probiotic strains and prebiotic fibres begin re-populating your gut microbiome. You may feel less bloated within days. Skin might get slightly worse before it gets better — that's normal.

  2. Week 3-4

    Your first period on the protocol.

    The premenstrual flare should be less severe or less cystic than usual. Not gone yet — but the ceiling of the breakout is lower. Bloating is typically noticeably reduced.

  3. Week 5-8

    Second cycle. Real changes.

    By your second cycle on the protocol, most women see fewer breakouts, faster healing, and less inflammation around jaw and chin. Post-acne marks from previous cycles begin fading.

  4. Week 9-12

    The new baseline.

    By month three, most women describe their premenstrual skin as "a totally different experience". The cycle still exists — but the skin doesn't take the hit anymore. This is the point at which most switch to the subscription and never look back.

REAL WOMEN, SAME PATTERN

The cycle changes.The skin doesn't have to.

"I've had cyclical acne since I was 22. Nothing lasted. On month three of Radiance Powder my period came and I actually forgot to check my chin. That's when I knew."
— Julia, 31, Vienna
"I always got a huge cyst on my jaw before my period. Doctors offered the pill, then Accutane. This was the first thing that just... let it not happen."
— Marie, 28, Copenhagen
"The bloating went first. Two weeks in I felt lighter, less puffy. Then the skin followed. My hormonal breakouts are 80% smaller now."
— Anna, 34, Berlin

THE FORMULA BUILT FOR THIS

Antoneta, founder

"I designed Radiance Powder around the gut-hormone-skin axis because I lived this. Once my gut could clear hormones properly, my cycle stopped showing up on my face. It's the same protocol I still take today."

COMMON QUESTIONS

Before you decide.

Five things women ask before starting. Honest answers, not sales copy.

  • "I'm already on the pill / IUD." — Radiance Powder complements both. The gut microbiome still needs support regardless of hormonal contraception, and many women see improvements even when their contraceptive alone was insufficient.
  • "Won't this affect my hormones?" — No. Radiance Powder doesn't add hormones or hormone-mimicking compounds. It supports your body's own elimination pathway — the estrobolome — so your existing hormones cycle cleanly.
  • "I've tried probiotics before. They didn't help." — Most consumer probiotics have 1-3 strains at low potency. Radiance Powder combines 13 clinically-selected strains with prebiotic fibres — the fibres feed the strains so they actually establish in your gut.
  • "Can I take it if I'm on Accutane / antibiotics?" — Ask your doctor first, especially with Accutane. In general, probiotics help repopulate the microbiome antibiotics wipe out, which is why many dermatologists actively recommend them alongside.
  • "What if it doesn't work for me?" — 30-day money-back guarantee. If after 30 days of consistent use you see no change, full refund — no return required. That said, most cyclical patterns need 2-3 cycles to shift, not 30 days.
