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?
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."
