Inglot Extend the life of AMC Gel Eyeliner by closing the lid between uses and keeping the protective foil inside the packaging. Due to its creamy formula that dries quickly, do not apply Duraline directly inside the product; instead, take a small amount on the lid or a professional palette for mixing, where you can experiment and mix products. Additional usage tips include applying directly to the eyelid as a base for intensifying eyeshadows or pigments, mixing with Duraline for precise application, using pearlescent or metallic shades as an eyeshadow across the eyelid, or coloring brows with the desired shade using a brow brush (e.g., brush 14M).
