PREMENSTRUAL SKIN SUPPORT

Why your skinchanges with your cycle.

What happens hormonally in the days before a period, and why the gut is part of that conversation. Plus what is in our daily powder. 10,000+ orders delivered.

THE GUT-HORMONE-SKIN AXIS

Three systems.One recurring problem.

The connection between the gut microbiome and hormone processing is an active field of research. Here is what is known about it.

01THE HORMONES

Estrogen fluctuates. Every cycle.

In the days before a period, estrogen levels drop sharply while progesterone tries to compensate. This shift is normal and inevitable.

What the research describes:

  • Testosterone becomes relatively dominant → sebaceous glands produce more oil
  • Skin often reacts → particularly along the jawline
  • Vitamin B6 contributes to the regulation of hormonal activity

SIGNS HORMONES ARE THE TRIGGER

  • Estrogen falls in the days before a period
  • Progesterone rises, then falls too
  • Testosterone becomes relatively dominant
  • The pattern repeats with every cycle

02THE GUT

Your gut is supposed to clear excess hormones.

The gut microbiome — specifically the estrobolome — is the system researchers associate with processing estrogen. It is an active field of study.

What is discussed in this context:

  • The share of Bifidobacterium and Lactobacillus strains
  • Fibre and cruciferous vegetables in the diet
  • Bowel transit time
  • Antibiotics taken in the past 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.

The skin is often where changes elsewhere in the body become visible — which is why it is worth looking at more than the surface.

What we took from that:

  • We formulate for the inside and the outside
  • A daily food supplement, plus cosmetic formulas
  • Neither replaces the other
  • Both list what is in them

SIGNS TOPICALS AREN'T ENOUGH

  • We formulate for the inside and the outside
  • A daily food supplement, plus cosmetic formulas
  • Neither replaces the other
  • Everything that is in them is listed

HOW TO TAKE IT

The routine,honestly explained.

One scoop a day, mixed into water, juice or a smoothie. Here is what that looks like in practice.

  1. Daily

    One scoop, every morning.

    One scoop of Radiance Powder each morning, stirred into water, juice or a smoothie. It contains 13 bacterial cultures and prebiotic fibres, seven vitamins above 15% NRV, plant fibres and enzymes.

  2. With breakfast

    Before or with breakfast.

    We suggest taking it before or with breakfast, so it becomes part of a routine you already have. The daily dose is 5 g.

  3. At least 90 days

    Give it time.

    A food supplement is not a quick fix. We suggest giving it at least 90 days — which is also how long our money-back guarantee runs.

  4. Ongoing

    Part of the routine.

    Most people keep it as a daily habit at this point. A subscription saves 23% and can be paused or cancelled at any time.

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."

— Antoneta, Founder

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 is a food supplement and can be taken alongside hormonal contraception. If you are unsure, ask your doctor.
  • "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 bacterial cultures before." — Many products contain 1-3 strains. Radiance Powder combines 13 strains with prebiotic fibres, which serve as food for the cultures.
  • "Can I take it if I'm on Accutane / antibiotics?" — Ask your doctor first, especially with Accutane. Radiance Powder is a food supplement, not a medicine, and the decision belongs with the person treating you.
  • "What if it doesn't suit me?" — 90-day money-back guarantee. If you are not satisfied, you get a full refund — no return required.
