ONLYSKY BEAUTY Hydra Needle Fine Touch Derma Stamp 0.25mm - Single-Use Serum Applicator with 5ml Vial

This compact derma stamp combines a micro-needle tip with a 5ml vial and screw-thread design to let you load your own serum and disperse it evenly across targeted areas. The 0.25mm microneedles are ultrafine—thinner than a human hair—and intended for surface-level delivery. The unit is supplied empty; you add your chosen serum, sanitize per instructions, and use once before disposing.

How do I prepare and load the Hydra Needle applicator?

Prepare the device and your skin by following a simple sanitation and filling routine. This ensures the vial is clean and the serum is properly seated against the needle head for smooth delivery.

• Cleanse skin with warm water to remove oils and makeup.
• Soak the top of the vial 5–8 minutes in 75% alcohol, then rinse the vial with alcohol to disinfect.
• Pour your chosen serum into the 5ml vial, tighten the screw cap, and gently shake 2–3 times to distribute.
• Remove the safety cover only when you are ready to use the device on skin.

What is the needle size and how does it affect use?

The microneedles measure 0.25mm in length and are very thin in diameter, designed for superficial delivery of liquids rather than deep penetration. Their small size supports even distribution across the treated area while minimizing superficial disruption to the skin surface.

• Needle length: 0.25mm (surface-level application).
• Needle diameter: ultra-thin, comparable to or thinner than a human hair.
• Designed to transport liquid formulations directly to the skin’s outermost layer.
• Not intended for repeated use—single-use only to maintain hygiene.

How should I use the Hydra Needle during an at-home session?

Use gentle patting motions to work the serum into your skin until it is absorbed. Avoid excessive pressure and follow a routine that targets one area at a time for even application.

• After removing the protective cap, lightly pat the device across the chosen area until the serum is absorbed.
• Work in small sections to ensure even coverage and avoid overworking any spot.
• Dispose of the applicator after one use to maintain safety and hygiene.

Are there special care or safety notes I should know?

Sanitation and single-use policy are key to safe operation. Use only recommended alcohol concentrations for disinfecting the vial and always discard the tool after one application.

• Sanitize vial tops with 75% alcohol before and after filling as directed.
• Do not reuse the applicator; it is a one-time-use device.
• Keep the protective hygiene cover in place until immediately before use.
• Store filled vials upright and follow any storage guidelines for the serum you use.

Who is this for: The ONLYSKY BEAUTY Hydra Needle Fine Touch is suited to people familiar with at-home topical application tools who want controlled, surface-level delivery of serums. It fits well for users who prefer to choose their own active formulas, professionals who need a compact single-use applicator for controlled treatments, and anyone seeking a precise, hygienic way to apply liquids without a bulkier device. Not intended for multiple uses—follow all sanitation steps and manufacturer guidance for safe handling.
