It keeps coming back because
you're treating one place.

Skin, nails, shoes, socks. The fungus lives in all four — clear one and the other three put it right back. That's not a stubborn case. That's an untreated environment.

◆ START HERE

Where did yours start?

Most people treat the symptom they can see and miss where it's coming from. Pick the one that matches — we'll point you at the right starting product.

PATH 01 · SKIN

Itching, peeling, cracked skin

Between the toes, on the sole, or spreading to the sides. Burns worst at the end of a long day in shoes.

Start with the soap

$29.95

PATH 02 · NAILS

Thick, yellow or crumbling nails

One nail or several. Usually started on a big toe and spread. You've stopped wearing open shoes because of it.

Start with the pen

$44.95

PATH 03 · THE LOOP

Both — and it keeps returning

Skin clears, nails don't. Or it clears and comes back every few months. This is the loop running in full.

◆ THE PART NOBODY TOLD YOU

Four places. Not one.

This is why it cleared and came back. Every time.

01

Your skin

Where you see it. Where you treat it. The only place anything ever gets applied.

02

Your nails

Same fungus, denser keratin. Soap physically can't get in there.

03

Your shoes

Spores outlive your skin clearing. Every morning you step back into the source.

04

Your socks

A normal wash cycle doesn't reliably kill fungal spores in fabric.

Treat one point — the other three refill it.

◆ VERIFIED PURCHASES

Four to six weeks apart

Same person, same lighting, roughly a month between shots. Nail cases run longer — nails grow out rather than heal.

Athlete's foot

6 WEEKS

“Constant itching and peeling between my toes for years. A few weeks in, the burning stopped. It hasn't come back.”

◆ HONEST COMPARISON

Why not just use a cream?

A 15 g tube used twice daily on both feet lasts about ten days. An $8 cream is closer to $24 per cycle — and it only ever reaches one of the four places.

◆ BEFORE YOU ASK

Questions we get every day

I've tried the pharmacy creams. Why would this be different?

Those use real actives — but they sit on dry, closed skin while the fungus hides under a biofilm. Sanidermis works during the wash and breaks that shield down first. Same enemy, different point of contact.

Why are there six products?

Because the fungus lives in four places, not one. Most people treat the skin, clear it, then get reinfected from their nails, shoes or socks within weeks. Each product handles one point in that loop — and you don't need all of them unless all four are involved.

Should I start with the soap or the pen?

Skin symptoms — itching, peeling, cracking — start with the soap. Thick, yellow or crumbling nails — start with the pen. If it's both, or it keeps coming back after clearing, the bundle covers the whole loop and works out cheaper than buying them separately.

How long before I see something?

Skin: itching eases within days, appearance improves clearly by week four. Nails are slower — first signs at 3–6 weeks, visible clear nail at the base around weeks 8–12. Nails grow out rather than heal, so that part can't be rushed.
