"L31’s hybrid silicone-wax matrix (48% dimethicone content) prevents dehydration:

Forms a breathable film that slows water loss by 65% (TEWL test verified)
Contains hydrogenated polyisobutene to fill lip ridges (16µm smoothing effect)
pH-adjusted pigments (4.5-5.0) avoid alkaline-triggered flaking
⚠ Key Detail: Apply thin layers – cures fully in 90 seconds for transfer-proof wear."

2. How Does the Glossy Side Give High-Shine Without Sticky Residue?

"L31’s low-viscosity copolymer blend (7,500 cPs at 25°C) creates glass-like reflectivity:

12% lower tack than traditional glosses (ASTM D5725-99 tested)
Refractive index-matched oils (1.485 RI) maximize light bounce
Hydroxylated esters prevent stringiness during application
💡 Pro Tip: Layer over matte side for 3D ombré effect lasting 6+ hours."

3. Why Can L31’s Dual Formula Be Layered Without Pilling?

"L31 uses cross-compatible film formers in both formulas:

Matte side: acrylates/octylacrylamide copolymer (bonds to keratin)
Gloss side: PVP/dimethiconol copolymer (interpenetrates without lifting)
Shared isododecane solvent ensures seamless blending
✨ Viral Hack: Apply gloss only to center of matte lips for illusory plumping."
