1. It's simple! Take pictures & videos of your eyelashes or eyebrows before applying the eyelash or eyebrow serum.

• The pictures & videos must be in 16:9 format and there must be no watermarks, such as from TikTok or Instagram. Therefore, do it directly via your mobile phone camera.

2. Use the serum until you see really great differences and again take pictures & videos in 16:9 format.

• Pictures & videos where the eyelashes were simply mascaraed do not count. You have to see really great differences without and with mascara.
