Soft FX vs. Glycerin: Which Should Be in Your PMU Toolbox?
If you’ve ever struggled with pigment that’s too thick, drying too fast, or just not implanting the way you want—it might not be your technique. It might be time to customize your pigment’s consistency with the right product. So what’s the difference between Soft FX and Glycerin, and when should you reach for each? Let’s break it down.
What Is Soft FX?
Soft FX is a specially formulated pigment dilution solution created by the Li Pigments Lab to work seamlessly with all Li Pigments—and other professional pigment brands.
✅ Made for machine and microblading artists
✅ Thins pigment without compromising safety
✅ Designed to help create a soft, powdery effect
✅ Compatible with brow, lip, eyeliner, and areola pigments
A few drops of Soft FX will thin out thick pigments and gently soften the overall intensity. If you're going for that whispery, airbrushed healed result, especially in powder brows or lip blush, this is your secret weapon. It’s ideal for creating sheer washes of color or adjusting pigment flow based on the area you’re working on.
💡 Pro Tip: Add Soft FX gradually and mix thoroughly—don’t over-dilute.
What Is Glycerin?
The Glycerin sold at the Girlz Ink Store is also made by Li Pigments, sourced from high-quality, Vegan and Kosher ingredients and tested for purity.
✅ Keeps pigment wetter longer
✅ Great for microbladers doing pigment soaks
✅ Doesn’t change pigment intensity—only consistency
If you notice your pigment is drying out too quickly during a procedure—especially in drier environments or slower sessions—Glycerin is the fix. It keeps pigment moist longer, which is critical when doing masking, shading, or soaking techniques.
🧴 Use 2–3 drops to adjust consistency—without shifting color.
