Precautions for the H2
H12 -0.25 mm:
This length of H2 cartridge is often used for beginners or sensitive skin to help improve dullness, dryness, and mild roughness. It is a popular choice for entry-level hydra pen microneedling.
H12-0.5 mm:
In hydra pen treatment, 0.5 mm can effectively stimulate skin renewal and accelerate the absorption of essence, making it very suitable for users who want to improve skin texture and reduce fine lines.
H12 -1.0 mm:
More suitable for experienced or professional caregivers, not recommended for thinner areas such as the eye area.
Nano-S:
Non-pinhole, ideal for sensitive muscles or first-time hydra pen H2 users.

Used to improve skin texture and slightly polish the surface cuticle. Suitable for dark, rough, and lackluster people's use.
