Can I put other cosmetics or purified water in Hyfuser?

DOSIÉ FLUID 01 or 02 is recommended, and other cosmetics, ampoules, serums, or toner should not be used. Purified water may be used, but a fault confirmed after inspection to have resulted from that use is not covered under warranty.

How many uses are in one FLUID vial?

One 10mL vial provides approximately 15 uses. The actual number varies with the amount and method of each use.

Can I use FLUID 01 and 02 together?

Start with one at a time. Choose 01 when skin looks dry or dull, and choose 02 when texture or tone looks uneven. Then check how your skin feels.

What should I do if the spray is weak or stops?

Stop use and lightly tap the device body with your fingertips to help the FLUID reach the spray unit, then try it again. Do not hit the device hard or turn it over and shake it. If there is no improvement, wipe the nozzle and contact area, check the FLUID level, charge, and vial fit, then submit a service request through DOSIÉ CARE.

Hyfuser Dedicated Fluid Guide | FLUID 01 vs 02 | DOSIÉ

Learn what to use in Hyfuser, how FLUID 01 and 02 differ, and what to check when the spray feels weak.

Start Hyfuser with dedicated fluid.

Purified water may be used with different warranty coverage. Start with spray performance, nozzle care, and how to choose FLUID 01 or 02.

What goes inside shapes the routine.

Hyfuser is a skincare device for applying fluid in a thin, even layer. Ingredient names matter, but so do formula texture, spray consistency, and nozzle condition. DOSIÉ guides use around dedicated FLUID 01 and 02.

Check these basics first

On the first day, set the device and fluid conditions before experimenting with more ingredients.

Basic: Dedicated fluid. DOSIÉ FLUID 01 or 02 is recommended. Purified water may be used, but a fault confirmed after product inspection to have been caused by purified-water use is not covered under warranty.
Choice: 01 for radiance, 02 for texture. Choose 01 when skin looks dry or dull. Choose 02 when texture or tone looks uneven. Start with one fluid at a time.
Care: Tap lightly if the spray is weak or stops. Stop use and lightly tap the device body with your fingertips to help the FLUID reach the spray unit, then try it again. Do not hit the device hard or turn it over and shake it.

Dedicated FLUID is recommended; check the purified-water warranty limit.

Other cosmetics can change spray performance and nozzle condition. Purified water may be used, but faults confirmed after product inspection to have resulted from that use are excluded from warranty coverage.

DOSIÉ recommends FLUID 01 and 02.
Do not add other cosmetics, ampoules, serums, or toner.
Product inspection determines whether purified-water use caused the fault before warranty coverage is decided.
For the first use, avoid custom mixes and start briefly with an official fluid.

FLUID 01 and 02 have different roles.

01 and 02 are not scent or version differences. Choose 01 for a radiance routine on dry or dull-looking days. Choose 02 when texture or tone looks uneven.

FLUID 01 is a radiance routine based on NMN, 24K Gold, and nanodiamond.
FLUID 02 is a soothing and tone-care routine based on PDRN, panthenol, and nanodiamond.
On sensitive-feeling days, use one fluid lightly instead of layering both.

If the spray is weak or stops, tap the body lightly.

Stop use, lightly tap the device body with your fingertips to help the FLUID reach the spray unit, then try operating it again. Do not hit the device hard or turn it over and shake it.

After tapping lightly, try operating the device again.
If there is no improvement, wipe dried fluid from the nozzle and contact area.
Check the FLUID level, charge, and vial fit, then submit a service request through DOSIÉ CARE if the issue continues.
