Stamp and hydrate in one step. A Hydra Stamp is a microneedling tool with a built-in serum chamber designed to apply serum while creating controlled micro-channels in the skin's surface. The Beautimate Adjustable Hydra Stamp features a 10ml refillable glass chamber, 24 stainless steel needles, and an adjustable depth dial from 0.25 to 1.5mm. As you stamp, serum is delivered directly through the needle head — reaching the skin exactly where micro-channels are open. No batteries. No cartridges. Fully manual. Pair with Hyah Serum for face routines. For scalp routines using rosemary oil or thicker serums, apply directly to the skin after stamping. .tabs { margin-top: 20px; } .tab-label { cursor: pointer; font-weight: bold; padding: 10px; border-bottom: 1px solid #ccc; background: #f9f9f9; display: block; } .tab-content { display: none; padding: 10px 0; } input[type="checkbox"]:checked + .tab-label + .tab-content { display: block; } ✓ Adjustable Depth 0–1.5mm ✓ Built-In Serum Reservoir ✓ Works on Face, Eye Area & Lips ✓ No Batteries, No Charging
