Purple Professional offers two essential primers designed to prepare the natural nail and improve adhesion: No Acid Primer and Primer SOS. Although they may look similar, each one is created for a specific nail type and plays a critical role in long-lasting, lift-free nail applications. This guide explains, in detail, the differences between the two primers based on the official Purple Professional chart.
No Acid Primer
The No Acid Primer is an acid-free formulation that prepares the natural nail by reinforcing the adhesion of the product applied afterwards. It is the gentlest primer in the Purple Professional range and is ideal for clients with normal or dry nails.
According to Purple Professional (official image):
- Acid-free formula
- Prepares the natural nail safely
- Strengthens adhesion without causing irritation
- Recommended for normal / dry nails
Primer SOS
The Primer SOS is an acid-based primer that creates maximum adhesion for difficult nail types. It is more powerful than the No Acid Primer and is specifically designed for nails that naturally resist adhesion or tend to lift.
According to Purple Professional (official image):
- Acid-based formula
- Creates strong adhesion for problematic nails
- Ideal for clients with challenging adhesion issues
- Recommended for difficult / sensitive / oily nails
Which Primer Should You Choose?
| Nail Situation | Recommended Primer |
|---|---|
| Normal nails | No Acid Primer |
| Dry nails | No Acid Primer |
| Oily nails | Primer SOS |
| Persistent lifting | Primer SOS |
| Hormonal changes | Primer SOS |
| Sensitive nails | Primer SOS |
How to Apply Purple Professional Primers
- Prepare the nail by removing shine and cleaning the surface.
- Apply a thin layer of Nail Prep.
- Apply a very light amount of primer (No Acid or SOS) — it must not pool or look wet.
- Allow to air dry for 30 seconds.
- Proceed with base gel, builder gel, acrylic, or acrygel.
Common Mistakes to Avoid
- Using Primer SOS on nails that don’t need extra adhesion
- Applying too much primer (causes lifting)
- Touching the skin with primer (risk of irritation)
- Skipping Nail Prep before primer application
- Using No Acid Primer on very oily nails
