The real problem

You're not forgetting your skincare. Vitamin C just isn't built into your routine yet.

Most women know Vitamin C works. They buy the serum. They use it for 3 days. Then life happens — and the bottle sits there, half-empty, for months.

The problem isn't motivation. It's the format. Anything you have to remember to apply will eventually be skipped. AUNAYA makes Vitamin C impossible to forget — because it's in your water.

Vitamin C delivered at the source

Stabilized Vitamin C is infused directly into your water — the moment it touches your face, the treatment begins.

Automatic consistency — 730 times a year

Twice a day, every day. You wash your face anyway — AUNAYA just makes every single wash a Vitamin C treatment.

Chlorine neutralized — bonus benefit

Vitamin C also neutralizes tap water chlorine on contact — protecting your skin barrier from daily damage.

How it works

From box to Vitamin C in under 60 seconds

No tools. No routine change. AUNAYA attaches to your faucet and delivers Vitamin C invisibly from day one.

1

Attach to your faucet

Clips onto any standard bathroom faucet in under 60 seconds. 5 adapters included. No tools needed.

2

Vitamin C infuses your water

Switch to Vitamin C mode and every drop that flows delivers stabilized Vitamin C directly to your skin.

3

Wash your face as usual

Nothing changes in your routine. AUNAYA works silently, automatically, every single time you wash your face.

4

See results in 2–4 weeks

Brighter glow, softer texture, more even tone — results that build every day, automatically.

The AUNAYA difference

The Vitamin C you keep forgetting — AUNAYA does it for you.

Serums work. The problem is consistency. You use them 3 days, skip 4, use them again, forget for a week. Results never come because Vitamin C only works when applied every single day. AUNAYA makes that physically impossible to skip — because it's built into the water you already use.

"I used to forget my Vitamin C serum constantly — like 4 days out of 7. I knew it wasn't working because I wasn't consistent. With AUNAYA, there's nothing to remember. I wash my face and it just... happens. My skin has never looked better."

"The problem was never the serum. It was me forgetting it. With AUNAYA I've been 100% consistent for 2 months without even trying. My skin tone is the most even it's ever been."

"My aesthetician asked what I changed. I told her: just my water. My skin looks brighter, feels softer, and I genuinely haven't done anything differently."

"Two kids, zero time. My Vitamin C serum sat on the shelf most days. AUNAYA fixed that. It's built into washing my face. More results in 5 weeks than in a year of trying."

FAQ

Your questions, answered.

Everything you need to know before trying AUNAYA.

AUNAYA is a faucet diffuser that attaches to your bathroom sink in under 60 seconds. Every time you wash your face in Vitamin C mode, it infuses stabilized Vitamin C directly into your water — delivering antioxidant protection the moment water touches your face. As a bonus, it also neutralizes tap water chlorine on contact.

The result: consistent Vitamin C, twice a day, automatically — without adding a single step to your routine.

Most users notice their skin feels less tight and more comfortable after washing within the first few days. Visible results like improved radiance, softer texture, and more even skin tone typically appear within 2 to 4 weeks.

Because AUNAYA works automatically every time you wash your face, consistency is built in — which is exactly what makes Vitamin C results compound over time.

AUNAYA comes with 5 standard faucet adapters that fit the vast majority of bathroom faucets. Installation takes under 60 seconds — no tools required.

If none of the 5 adapters fit your faucet, simply send us a photo and we will ship you a custom adapter, completely free of charge.

AUNAYA has two modes:

Standard mode — regular water for everyday tasks like washing your hands.
Vitamin C mode — activates the cartridge. Use this every time you wash your face.

This means your cartridge is only used when it counts — maximizing its 45-day lifespan.

Yes. AUNAYA is safe for all skin types, including sensitive skin. The formula contains no parabens, no fragrances, no harsh chemicals — only stabilized, food-grade Vitamin C. It is also safe during pregnancy and breastfeeding.

Simple and fully flexible:
