【COSNORI】 COSNORI Easy Brow Tone Changer This is a self-use eyebrow bleaching agent. Contains 5 applications. Purchased from COSNORI's official online store. It turns your eyebrows brown in about 3 minutes, and light brown in about 5 minutes. My personal experience: The 9th photo shows an example of use after 3 minutes. Even thick eyebrows became lighter. To protect my skin, I applied Vaseline to the skin before applying the solution. I felt less stinging compared to the famous bleaching agents from Korean cosmetics. When used in conjunction with perms like Hollywood Eyebrow, it puts a strain on the eyebrows, and I felt like the amount of hair decreased. I think it's better to leave some time between uses. This is just my personal opinion, but I hope it helps. COSNORI is a popular brand of eyelash serum in Olive Young, Korea, so I think you can use it with confidence. It comes in single-use packs, so it's also recommended for trying out. 5 applications. Please refrain from requests for price reductions.
