Questions & criticism about products & quality at COSLINE

Are the kohl/eyeliner really smudge-proof and waterproof?
Yes, the kohl/eyeliner is smudge-proof and waterproof after 5 minutes. Until then, you still have time (if you want) to correct or blend the color. It is important that you do not apply a lot of cream to your skin shortly before applying makeup, as this makes it difficult for the colors to stay. And it is best not to apply the line directly to the waterline (because it is very moist there) but to the base of the hairs.

Are the products really free from animal testing?
Yes! Since 1998, animal testing on cosmetic products has been prohibited in Germany. In the EU, animal testing for cosmetics has been banned since 2004. In addition, since March 2013, there has been a ban on the introduction of cosmetics and their ingredients tested on animals in the EU.
COSLINE products are manufactured in accordance with the above-mentioned laws and regulations with "Made in Germany" quality. Consequently, our finished cosmetic products are not tested on animals and we do not commission any animal testing for individual raw materials.

Are COSLINE products of poor quality?
No, because we rely on high quality in our production - Made in Germany. It is important to us that you get the best product. If that doesn't work out, you can easily contact our customer service and we will find a solution.

It is important to us that everyone can easily put on make-up without being a make-up professional.

So you can be 100% sure that you only get the best from us. We only include products in our range that we are convinced of ourselves.
