REVIEWED BEFORE LISTING
Why HARUNARU curated GASH
We list a brand only after our own verification. GASH passed on paper and in practice — and it fits the way we believe a daily routine should work.
Documentation, reviewed
CPNP notifications for all four masks, an EU Responsible Person in place, safety assessments and certificates of analysis on file, and a manufacturer certified to ISO 22716 (GMP).
Tested in real routines
Before listing, the HARUNARU team ran a five-day real-routine trial to confirm the 10-second step holds up in everyday use.
A fit for calm routines
One quick no-rinse step suits our philosophy: short, structured skincare — consistency over hype.
One step, ten seconds, no rinse
GASH’s Air Bubble CDS micro-bubble texture turns the formula into an airy mousse you press into skin like an essence. Shake the can, spread a coin-sized amount, wait about ten seconds and gently pat it in — no rinsing. In the morning, continue with makeup. At night, use it as the final mask step.
How to use it
- Complete your usual skincare, morning or evening.
- Shake the can and dispense a coin-sized bubble mousse.
- Spread over the face, avoiding the eye area.
- Wait about ten seconds, then gently pat it in — do not rinse.
- Continue with makeup in the morning, or leave it on as the final mask step at night.
