Why Topical Skincare Isn’t Enough: 
The Inside-Out Solution to Acne That Finally Works

Written by Dr. Lars Rüther, Skincare & Gut Health Specialist 

Published on February 05, 2025

For years, I’ve worked with patients desperate to clear their acne—patients who have spent hundreds, if not thousands, of dollars on skincare products that promised to transform their skin but never delivered lasting results.

If you’ve been on this exhausting journey, I want you to know: it’s not your fault.

Most acne treatments focus only on the surface—but acne isn’t just a skin issue. The breakouts you see in the mirror are often a symptom of an internal imbalance linked to gut health, hormones, and inflammation.

Why Your Gut Health Is the Key to Clear Skin

It may surprise you, but your skin and your gut are deeply connected. Scientists call this the gut-skin axis, and it explains why an imbalanced gut microbiome can trigger acne, inflammation, and breakouts.

 

Your gut is home to trillions of bacteria—some good, some bad—that play a direct role in how your skin behaves. When the gut microbiome is off-balance (due to diet, stress, antibiotics, or other factors), harmful bacteria multiply, leading to increased inflammation, poor digestion, and toxin buildup.

1️⃣ Inflammation Triggers Breakouts: 
When your gut is out of balance, harmful bacteria thrive, causing systemic inflammation that can lead to persistent acne, redness, and irritated skin. If your skin is constantly inflamed, no amount of topical treatments will provide lasting relief.

2️⃣ Toxins Build Up and Show on Your Skin: 
A sluggish digestive system can fail to eliminate toxins properly, forcing your body to push them out through your skin—resulting in breakouts, dullness, and congestion. Poor gut health can make acne worse by allowing toxins and bad bacteria to thrive.

3️⃣ Nutrient Absorption Is Compromised: 
Your skin needs essential vitamins and minerals like B vitamins, Vitamin C, and Zinc to heal, repair, and stay balanced. When your gut isn’t functioning properly, your body struggles to absorb these nutrients, leaving your skin vulnerable to breakouts and slow healing.

4️⃣ Hormonal Imbalances Cause Persistent Acne: 

Your gut and hormones are directly connected. If your microbiome is out of balance, it can lead to fluctuations in androgens and estrogen, which often result in hormonal acne, especially around the chin and jawline. Balancing your gut is key to regulating hormones and preventing breakouts.

The best way to clear your skin isn’t just by using topical treatments—it’s by restoring gut balance with probiotics, prebiotics, and anti-inflammatory nutrients to heal your skin from within.

1. Probiotic Bacteria Strains: Balance the Gut & Reduce Skin Inflammation

The most powerful way to heal the gut and, in turn, clear acne is with probiotics. Radiance Powder contains 12 clinically researched strains of probiotics, including:

  • Bifidobacterium Bifidum & Bifidobacterium Lactis – Reduce gut inflammation, boost digestion, and prevent toxin buildup that worsens breakouts.
  • Lactobacillus Acidophilus & Lactobacillus Rhamnosus – Proven to reduce acne severity by promoting a healthy microbiome and strengthening the skin barrier.
  • Lactobacillus Plantarum & Lactococcus Lactis – Help to calm skin irritation, balance oil production, and prevent recurring breakouts.

🌿 The result? A balanced gut microbiome, reduced inflammation, and clearer skin that stays clear—without the side effects of harsh acne treatments.

2. Inulin & Psyllium Husk: Prebiotic Fibers That Detox & Reduce Bloating

Your gut bacteria need fuel to thrive. That’s where prebiotics come in.

Radiance Powder contains Inulin & Psyllium Husk, two fiber-rich prebiotics that:

Feed beneficial gut bacteria, making the probiotics more effective
Support digestion and nutrient absorption, so your skin gets the vitamins it needs to heal
Detox the body by removing toxins that trigger breakouts
Reduce bloating and constipation, improving gut function and overall skin health

🌿 The result? A cleaner, healthier gut environment that promotes a clear, radiant complexion.

3. Vitamin B Complex & Folic Acid: Regulating Hormones for Acne Control

Hormonal fluctuations are a major cause of acne, especially for women dealing with breakouts around their chin, jawline, and cheeks.

Radiance Powder includes essential B vitamins & folic acid that:

Support healthy hormone levels, reducing breakouts linked to imbalances
Boost skin healing and repair, helping to fade acne scars faster
Control oil production, preventing clogged pores and new blemishes

🌿 The result? Fewer hormonal breakouts, faster skin recovery, and a more balanced complexion.

4. Papaya & Pineapple Enzymes: Gentle Skin Detox & Anti-Inflammatory Power

Inflammation is the root cause of red, irritated, and painful acne.

Radiance Powder is enriched with Papaya & Pineapple enzymes, natural anti-inflammatory compounds that:

Reduce redness & swelling, calming inflamed acne
Break down excess sebum, preventing clogged pores
Support gut health & digestion, further balancing the skin

🌿 The result? Skin that looks calmer, clearer, and more even-toned.

From Science to Skin: How We Created Radiance Powder

At Klarskin, we believe that clear, healthy skin starts from within. That’s why the development of Radiance Powder was not just about creating another skincare supplement—it was about finding a science-backed solution that addresses the root causes of acne, inflammation, and gut imbalance.

 

Step 1: Identifying the Real Causes of Acne & Skin Imbalance

Traditional acne treatments only focus on the symptoms—drying out pimples, reducing oil, or masking breakouts. However, scientific research has shown that gut health, inflammation, and hormonal imbalances are major contributors to persistent acne and skin sensitivity.

We worked with leading dermatologists, nutritionists, and gut health experts to create a holistic formula that targets these issues at their source.

 

Step 2: Formulating the Perfect Gut-Skin Solution

To develop the most effective and bioavailable formula, we focused on three core pillars:

1️⃣ Clinically Studied Probiotics – A 12-strain probiotic blend was selected to help rebalance the gut microbiome, reduce systemic inflammation, and improve skin clarity.

2️⃣ Prebiotics & Digestive Support – We included Inulin & Psyllium Husk to promote digestion, reduce bloating, and help the body absorb nutrients essential for skin repair.

3️⃣ Anti-Inflammatory & Hormonal Balancing IngredientsBaobab Fruit, Vitamin B Complex, and Papaya Enzymes were carefully chosen to support hormonal health, detoxify the body, and provide deep skin nourishment.

This formula was rigorously tested to ensure optimal absorption and real, long-term results.

 

Step 3: Clinical Testing & Customer Trials

Before launching, we conducted independent consumer trials with individuals struggling with acne, digestive issues, and inflammation. After 30 days of consistent use, the results were remarkable:

 

90% noticed an improvement in overall skin clarity
85% reported reduced bloating and better digestion
80% saw a visible reduction in breakouts and redness

 

We also tested before-and-after microbiome samples, showing that Radiance Powder significantly improved gut flora diversity and balance, leading to long-term skin improvements.

 

Step 4: The Success of Radiance Powder

Since its launch, Radiance Powder has helped thousands of people worldwide finally achieve clear, healthy skin without relying on harsh treatments.

Today, Radiance Powder continues to be one of Klarskin’s best-selling products, with thousands of happy customers proving that healing your skin from within is the key to lasting results.

How to use the Radiance Powder

Step 1: Dosage

Add two scoops (5g) of Radiance Powder to water, juice, or a smoothie. Stir well until fully dissolved.

Step 2: Drink it in the morning

For optimal effects, drink Radiance Powder every morning on an empty stomach. Consistency is key—regular use helps your gut microbiome rebalance, leading to smoother digestion, reduced inflammation, and clearer skin over time.

Step 3: Support Your Skin from Within

Pair your daily Radiance Powder intake with a balanced diet, proper hydration, and a simple skincare routine for maximum results.

What our happy customers say

My body is thanking me by using a supplement to help itself heal from the inside.

I have taken The Radiance Powder 2 times in the last 2 years, usually after summer when I lose track of routines (lack of sleep, bad eating habits, drinking more than usual, etc.) and it is as if my body is thanking me by using a supplement to help itself heal from the inside.

Great product! It helps my skin every morning.

I drink the RP 10 min before coffee and breakfast each morning, I mix it with a cup of water and drink it in one go before the consistency gets thick (this is when the formula becomes active).  It does not really have any taste as there are no artificial preservatives or flavorings.

It´s been working an absolute dream so far!

I´ve had really bad acne in the past and my mum gave me the powder 2 months ago.  It´s been working an absolute dream so far! I have no idea how I didn´t know about this sooner but thank you, I really hope it keeps working as it has so far!

Jason P.

Verified Buyer

Can't recommend it enough!

I have used the Radiance Powder for a few months now after having awful skin (something I've never really suffered from) due mostly to a stomach infection. Not only did the probiotics in the powder clear my skin completely to the best it has been in years but also helped repair my gut health. I now tend to use this every few days to keep my skin clear and feel this is also helping with my overall digestive health so can't recommend it enough!!!
