Start by selecting a shade that flatters your lip undertone and a finish that fits your style. Double side lip liners often combine a liner and a filler in one pencil, so look for a formula that glides smoothly and wears well. Check that the product is vegan, halal, and cruelty-free if those values matter to you. For example, the IDA Beauty Edge & Enrich line offers creamy, long-wearing lip liners in brown and red tones with a matte finish.

Waterproof and smudge-proof mean the color resists rubbing and moisture so it stays put through the day. The formula typically combines a creamy base with a durable, matte finish that dries slowly to minimize feathering. In a true double side lip liner, one end outlines while the other can fill in for longer wear and a defined lip shape. Brand examples like IDA Beauty Edge & Enrich emphasize these properties in their 3 g pencils.

Beginner users should apply a light, steady outline along the natural lip line and use the filler end to gently fill in for a soft, clean look. Pro users can refine the edge with precise strokes, then employ the filler to sculpt and lock in color for a bold, defined finish. The dual-ended design helps you switch between lining and filling without switching products. Experiment with browns for everyday looks or reds for statement lips.

Keep the cap on when not in use and store the pencil away from heat to preserve the formula. If your pencil is sharpenable, use a suitable sharpener to maintain a fine tip for accurate lines. Pair it with a compatible lip primer or balm to reduce feathering and help color last longer. Gently remove with a makeup remover to protect your lips and preserve the product.

Brown and red shades are versatile and suit most skin tones, with red-grey offering a cooler option. Look for a reputable line like IDA Beauty Edge & Enrich, which provides a creamy, waterproof, matte finish in a 3 g pencil, and is vegan, halal, and cruelty-free. Choose a shade that matches your usual lip color or lip liner preferences for a cohesive look. Consider staying within the same brand for a coordinated result.

Pair the double side lip liner with a matching lipstick or matte lip color to complete the look. Add a lip primer for longevity and a lip liner sharpener if the pencil is sharpenable. Finish with a clear lip balm to keep lips comfortable, then remove with a gentle makeup remover at the end of the day. Using these tools helps maximize the performance of the IDA Beauty Edge & Enrich lip liners.
