Is Your Shower Water Making You Look Older?
If you're over 40 and your skin suddenly feels tight, dry, and dull no matter what products you use—it's probably not your skincare routine that's failing you.
It's your shower water.
Your shower water contains over 300 chemicals—chlorine, heavy metals, chloramines, and microplastics—all pushed through a system designed in the 1920s by men who never considered women's skin.
And after 40, when estrogen drops and your skin barrier naturally weakens, these harsh chemicals hit harder than ever before.
What Changes After 40
As estrogen declines, your body produces less of three protective elements:
- Collagen – Your skin becomes thinner and more vulnerable
- Ceramides – Your moisture barrier weakens
- Hyaluronic Acid – Your skin can't hold water like it used to
When these decline, your skin barrier is left wide open—and shower chemicals penetrate deeper, causing visible aging that happens twice a day, every day.
Why Radii Is Different
Radii uses a revolutionary 15-stage filtration system specifically designed for women over 40:
Removes 99.9% of chlorine, heavy metals, and harsh chemicals before they touch your skin
Infuses Vitamins A, C & E into the water while your pores are open—the exact nutrients dermatologists recommend for barrier repair
Boosts water pressure by up to 200% for a spa-like shower experience
The Results
Most women notice softer, less reactive skin within 24 hours. Within a week, rough patches soften and hydration lasts longer. By month one, their natural glow returns and their expensive serums finally absorb properly.
Your skincare routine doesn't need to change. Your water does.
How to use
+
Installation (Under 5 Minutes, No Tools Required)
Step 1: Remove Your Current Shower Head
Unscrew your existing shower head by turning it counterclockwise. Most come off easily by hand.
Step 2: Attach Radii
Screw the Radii filter onto your shower arm (the pipe from the wall) by turning clockwise. Hand-tighten until snug.
Step 3: Attach Your Shower Head
Screw your shower head onto the bottom of the Radii filter. Hand-tighten securely.
Step 4: Run Water for 30 Seconds
Turn on your shower and let water run for 30 seconds to activate the filtration system.
That's it. You're ready to shower with water made for your skin.
Daily Use
Simply shower as normal. Radii works automatically—removing harsh chemicals and infusing vitamins while you cleanse.
For best results, let warm water run over your face and body for 2-3 minutes to allow vitamins to absorb through open pores.
Filter Replacement (Every 1-2 Months)
When water pressure decreases or after 6-8 weeks of daily use, replace your filter cartridge:
- Unscrew the filter housing
- Remove old filter cartridge
- Insert new filter cartridge
- Screw housing back on
- Run water for 30 seconds
Replacement filters available on our shop page.

Frequently Asked Questions
Find answers to common questions about our products, shipping, returns, and more.
How long do the filters last?
+
Filter cartridges last approximately 1-2 months with daily use, depending on water quality. We recommend replacing when you notice decreased water pressure or every 6-8 weeks for optimal performance.
How is this different from other shower filters?
+
Most filters only remove some contaminants. Radii is the only system designed specifically for women over 40 that both removes harmful chemicals AND infuses skin-supporting vitamins A, C & E. It's water made for your skin, not just "cleaner water."
When will I see results?
+
Most women notice less tight, reactive skin within 24 hours. Visible improvements in hydration and glow typically appear within the first week. Full barrier restoration develops over 1-3 months.
Do I need a plumber to install it?
+
No! Radii installs in under 5 minutes with zero tools required. Simply unscrew your shower head, attach Radii, reattach your shower head.
What's included in my purchase?
+
Your Radii system includes: (1) Complete 15-stage filter housing, (1) Pre-installed filter cartridge, (1) Installation guide, and our 45-Day Money-Back Guarantee.
Can I use this with well water?
+
Yes, Radii works with both city and well water. However, well water may require more frequent filter changes depending on mineral content.
Is it safe for sensitive skin?
+
Absolutely. Radii is specifically designed for sensitive, mature skin. By removing harsh chemicals and adding skin-supporting vitamins, it's gentler than unfiltered water.

Not usually one to leave reviews but this actually works. I'm 52 and was skeptical about another "miracle" product. But after about 5 days I noticed my skin didn't feel tight and itchy after showering anymore. Now it's been 2 months and my skin looks healthier than it has in probably a decade. Even my hairdresser commented on how much better my hair looks. Highly recommend.
Patricia Hughes
Best investment I've made for my skin, hands down. I'm 55 and have tried literally everything - expensive facials, retinol, you name it. Nothing worked like I hoped. Radii fixed the problem I didn't even know I had. My water was destroying all the good stuff I was putting on my skin. Now my products actually work, my skin stays hydrated all day, and I look in the mirror and see myself again. The me I remember.
Sarah Mitchell
Honestly didn't expect much but WOW. I'm 47 and my skin has been so dry and flaky for the past few years, nothing seemed to help. Within the first week of using Radii my skin felt completely different - softer, less tight after showers. My serums actually sink in now instead of just sitting on top. Worth every penny.
Rachel Martinez
I was in tears before I found Radii. Menopause hit me hard and my skin just fell apart - dry, grey, irritated constantly. My dermatologist kept saying "it's just hormones" but I knew something else was wrong. One shower with Radii and I could feel the difference. The tightness was gone. Within two weeks my face actually had colour and life again. This gave me back a piece of myself I thought was lost forever.
Kelly Davies
This thing is magic. Within 3 days my skin felt completely different - softer, plumper, less dry. My fine lines around my eyes look so much better now because my skin is actually holding moisture. My husband even asked if I got a facial! I just shower normally and Radii does all the work. Obsessed.
Emerson Thompson
Game changer for my perimenopausal skin. I thought I just had to accept the dryness and dullness but turns out it was my water the whole time. My face doesn't feel like sandpaper anymore and those dry patches on my cheeks are completely gone. Wish I'd found this sooner!
Jenny Cole
Okay so I bought this because my daughter wouldn't stop talking about it lol. I'm 49 and honestly thought my skin was just done for. Took maybe a week before I noticed my moisturizer was actually absorbing instead of just sitting there. The redness on my cheeks has calmed down so much. My skin genuinely looks and feels better. Install was easy, results were real. Would recommend.
Michelle Andrews
I've had chronic eczema flare-ups on my arms and chest since turning 44. My dermatologist prescribed cream after cream but nothing helped long-term. Two weeks with Radii and the patches are 90% gone. My skin isn't constantly inflamed anymore. I can finally wear sleeveless tops without being self-conscious. This filter removed whatever was triggering my skin and I'm so grateful. Life-changing honestly.

15-Stage Advanced Filtration
Unlike basic filters that use 3-5 stages and miss most contaminants, Radii's 15-stage system targets every chemical that damages aging skin—removing 99.9% of chlorine, heavy metals, chloramines, and microplastics before they touch your face.
Vitamin A, C & E Infusion
Radii doesn't just remove the bad—it adds back what your skin needs. Hot water opens your pores, and Radii infuses skin-barrier supporting vitamins directly into the water for maximum absorption. It's the only filter designed specifically for women's skin, not just "cleaner water."
Designed for Women Over 40
As estrogen drops, your skin barrier weakens and becomes vulnerable to harsh chemicals. Radii was engineered specifically for mature skin that needs protection AND nourishment. Most filters were made for general use—Radii was made for you.
Spa-Quality Water Pressure
Most filters reduce water pressure, making showers feel weak and disappointing. Radii actually increases pressure by up to 200%, delivering a luxurious spa-like experience while protecting and nourishing your skin with every shower.

This is the best my skin has looked in YEARS. I've spent thousands on creams and treatments that barely made a difference. Three weeks with Radii and people are asking what I'm doing differently. My skin glows, my hair is shinier, and I finally understand what everyone was talking about. The installation was super easy too - took maybe 3 minutes.
