Questions, Feedback & Criticism about COSLINE
Before choosing a product, you want to be sure: Does it deliver what it promises? That’s exactly why you’ll find answers to frequently asked questions here, open responses to criticism, and an insight into how we handle feedback – transparently and directly.
Questions & Feedback on Products & Quality
Yes – our eyeliner pencils become smudge- and waterproof after about 5 minutes. This gives you time to correct the color or gently blend it at first. For the best results: avoid applying heavy cream to the skin beforehand and draw the line lightly along the lash line instead of directly on the waterline. This way, the color lasts especially long.
