Why has "single-use" become the new favorite in skincare? Aodod Onetouch serums—efficiency redefined.

China's single-dose serum market hit ¥7.5 billion in 2024, with year-on-year growth exceeding 20%.

66% of Sephora shoppers now prefer single-dose for potency assurance (NPD 2024), with TikTok's #singledoseskincare surpassing 200M views during Prime Day promotions.

You've seen them at Sephora - those convenient single-dose serums flying off shelves. But here's what even beauty insiders don't know: not all ampoules are created equal. While most focus on convenience, we solved the bigger problem - keeping powerful ingredients actually potent until you use them.

Here's how we fixed it:

1. We vacuum out the bad stuff first

Before filling, we remove 99% of oxygen (like how food lasts longer in vacuum-sealed bags)

2. Then add pharmaceutical-grade nitrogen

The same pure gas used to preserve hospital medicines creates an invisible freshness shield

3. Our ampoules actively fight oxygen

Special inner coating keeps absorbing stray oxygen molecules like a skincare sponge

What this means for you:

✓ Every dose works as powerfully as day one

✓ No more "did this serum stop working?" doubts

✓ Even unstable ingredients (like vitamin C) stay effective

"It's the difference between fresh-squeezed and store-bought orange juice - both are juice, but one just works better."
