Yes. And not because we say so.

Chlorine is a solvent. It dissolves fat. Your skin barrier is a fat layer. That is chemistry, not marketing.

Here is what the research already shows:

Journal of Investigative Dermatology, 2018. Washing in hard water leaves significantly more irritant residue sitting on the skin after rinsing, and that residue measurably damages the barrier. The effect was strongest in people who already had eczema.

Journal of Allergy and Clinical Immunology, 2016. Domestic water hardness mapped against eczema rates across a large population showed a clear association. Higher hardness, higher rates.

North American Contact Dermatitis Group. Nickel comes out as the most frequently positive allergen in patch testing, year after year. It is also one of the metals that sheds off older supply lines and arrives at your skin in the shower.

The Softened Water Eczema Trial. Fitting water softeners did not improve eczema. That result matters, because it tells you the hardness itself is not what is attacking your skin. It is what the water is carrying, and a softener does not take that out.

None of this is hidden or disputed. It is simply not on the form your dermatologist fills in, because there is no billing code for the water you rinse in.

Roselyn takes those irritants out before they reach you. In our customer survey, 92% reported fewer flare-ups after showering.

“Four weeks in I realised I had stopped bracing for the burn after I dried off. I had been doing that for six years without noticing.”
Marianne, 51, Oregon

“My allergy panel was clean, my patch test was clean, and I was still covering my arms in July. Nobody once asked me about my water.”
Teresa, 47, Illinois

“The cream I had used for years suddenly started working again. Same tube. That is the part I still cannot get over.”
Gail, 58, North Carolina

No. Vanto is a shower head with filtration built into the housing, not a puck you stack between the arm and your old head. Stacked filters cause the pressure drop people complain about. Most people say the spray feels slightly softer and more even.

Every Vanto arrives with a filter already inside it. Nothing else to buy, nothing to assemble. Screw it on and shower.

That first filter runs at full strength for about 3 months. After that the media is used up and it quietly stops doing the job. There is no light and no warning. The first thing that tells you is your skin.

Changing it takes about ten seconds. Twist the spent one out, drop the new one in, run the water for half a minute. Nothing comes off the wall, no tools, no plumber, and you can do it with wet hands.

Which is why most people add the year supply to their first order instead of reordering one at a time. It works out cheaper per filter, it ships in the same box, and you are never standing in the shower on month four wondering whether this one is still working.

Use it for 100 days. Run a full cartridge through it. If your skin is no calmer, email us and you get your money back. No form, no explanation, no original packaging.

1. Unscrew your old shower head by hand, counterclockwise.
2. Wrap the thread with the tape in the box.
3. Screw Vanto on until it is hand tight.
4. Run the water for 30 seconds to flush the cartridge.

Fits every standard half inch shower arm. No tools, no drilling, nothing permanent. If you rent, put your old head back on the day you move out.
