Hypoallergenic acid-free primer base eliminates thermal spikes and natural plate thinning.

Lamp burning is an exothermic chemical reaction. When UV or LED light strikes photo-initiators, chemical bonds snap and reconnect in milliseconds, releasing thermal energy. In cheap, mass-market bases, manufacturers overload formulas with inexpensive photo-initiators and volatile acids so the gel cures rapidly even in weak lamps. On thin natural nails, that heat transfers straight into the vascular nail bed, causing acute burn trauma.

Hypoallergenic Acid-Free Primer Base uses high-purity polyurethane oligomers and a dual-photo-initiator blend that meters the reaction rate. The temperature rise is gentle and sustained, staying under 34°C throughout the entire 60-second cycle. Clients feel zero burning or throbbing.

Because it contains 0% methacrylic acid, it does not dissolve the keratin bridges that hold the nail plate to the nail bed. It bonds mechanically by penetrating the microscopic surface texture created by a fine 180/240 buffer.

On clients with hyperhidrosis or naturally oily nail beds, skipping dehydration will cause lifting within five days. However, the solution is not burning the plate with 70% methacrylic acid primer; the solution is disciplined physical prep.

You must cleanse the nail twice with 99% isopropyl alcohol, apply an alcohol-based dehydrator, and allow 30 seconds for complete moisture evaporation. When this acid-free base is applied over a properly dehydrated plate, it achieves 12 to 16 days of adhesion without edge lifting.

Our manicure master, in salon practice since 2022, inspects every lot against manufacturer batch records. We provide dated invoices and product certificates confirming that the acid-free specification is chemically genuine.

No. This base is formulated at a fluid 3,200 mPa·s viscosity specifically to lay down an ultra-thin, flexible bonding coat of less than 0.2 mm. If you try to deposit a heavy architectural bead, it will flow into the eponychium and cuticles before reaching the lamp.

If your client has sensitive nails and also needs structural apex alignment, use this acid-free base as a primer bonding layer, cure it for 30 seconds, and then overlay our Dense Rubber Base ($14 USD per 15 ml). That protocol gives you gentle hypoallergenic contact with the natural plate plus high-viscosity structural strength above.
