1. How Does the L13 Dual-Ended Lip Gloss Achieve Long-Lasting Wear Without Drying Out Lips?"The L13 Dual-Ended Lip Gloss combines a moisturizing base layer (with hyaluronic acid) and a liquid-powder topcoat that locks in color for 8+ hours.The formula is non-sticky, transfer-resistant, and feels weightless—no flaking or tightness!"2. Can I Use Just One Side of the L13 Lip Gloss, or Do I Need Both for Full Effect?"While each side works alone (the creamy base gives sheer color, the liquid-powder topcoat adds full-coverage shine), combining both creates maximum longevity and dimension.For quick touch-ups, the topcoat alone refreshes color!"3. Is the L13 Gloss Suitable for Sensitive Lips or Under-Lipstick Application?"Absolutely!The hypoallergenic, fragrance-free formula is gentle on sensitive lips.Use the moisturizing base as a primer under lipstick to prevent cracking, or wear solo for a natural tint.(Tip: Avoid the topcoat if you prefer no-pick transfer.)"
