The Science
Why your skin is dry.
What we do about it.
Hard water is a chemical problem. QUELL is a chemical solution. Here's the exact mechanism.
The Mechanism
How Hard Water Breaks Your Skin
Hard water deposits land on your skin
Every shower leaves behind calcium and magnesium ions. They don't rinse off — they bind to your skin's surface and stay.
Your lipid barrier degrades
Mineral deposits disrupt the tight junction between skin cells. Your natural ceramide layer thins. Transepidermal water loss (TEWL) goes up.
Chronic dryness, tightness, sensitivity
Without a healthy barrier, water evaporates faster than your skin can replenish it. The result: persistent dryness that moisturiser alone can't fix.
QUELL chelates, repairs, defends
EDTA binds and neutralises the mineral deposits. Ceramides NP, AP, and EOP restack the lipid layer. Niacinamide reduces inflammation and rebuilds skin protein.
The Formula
Three actives. One system.
Barrier Rebuilder
Ceramide NP + AP + EOP
Three ceramide subtypes that mimic your skin's natural intercellular lipid matrix. Applied together, they restack the lamellar structure that hard water degrades.
Mineral Chelator
Disodium EDTA
Binds calcium and magnesium ions at the skin surface — the exact minerals that hard water deposits after every shower. Neutralises the damage before it starts.
Barrier Strengthener
Niacinamide 4%
Upregulates ceramide synthesis, reduces TEWL, inhibits inflammatory cytokines. Clinically shown to improve barrier function in 4–8 weeks of use.
Research Backed
The evidence base
Ceramides restore the skin barrier
Clinical studies show topical ceramide application significantly reduces TEWL and improves skin hydration within 2–4 weeks of daily use.
EDTA chelates hard-water minerals
Disodium EDTA is a well-established chelating agent that binds calcium and magnesium ions, preventing them from interacting with the skin's surface proteins.
Hard water accelerates skin barrier damage
Bathing with hard water (>200 ppm CaCO₃) significantly increases skin surface pH and reduces barrier function compared to softened water.
Niacinamide reduces inflammation markers
4% niacinamide reduces IL-1α, IL-8 and significantly improves erythema and hyperpigmentation in 8 weeks of use.
