I’ve been a dedicated user of the CoverGirl Super Sizer Waterproof Mascara, which has consistently impressed me with its ability to hold my lash curls for longer than most mascaras. Recently, CoverGirl launched a fiber version of their Super Sizer Mascara, which intrigued me enough to test it out. In this detailed comparison, I’ll explore whether the new fiber mascara performs better than the waterproof version.
Overview of the Mascaras

Super Sizer Fibers Mascara
Claims:
- Volume: Promises to provide 400% more volume.
- Fibers: Contains built-in fibers intended to give a false-lash effect by extending the lashes.
- Appearance: The mascara is designed to make lashes look long, dark, and amplified.
Packaging and Wand:
- The fiber mascara comes in a purple tube, distinguishing it from the original.
- The wand is identical to the one used in the waterproof version, featuring a unique brush that helps coat and separate each lash.
Super Sizer Waterproof Mascara
Claims:
- Volume: Also claims to deliver 400% more volume.
- Lash Styler Brush: Uses a patented brush designed to transform small lashes for a fuller appearance.
- Waterproof Formula: Ideal for those who need their mascara to withstand water and sweat. It’s ophthalmologically tested and safe for contact lens wearers. It removes easily with an oil-based makeup remover.
Packaging and Wand:
- Comes in a classic black tube.
- The wand is the same as the fiber version, designed to maximize lash volume and separation.
Performance Test

To evaluate how well each mascara performs, I applied them to each eye under similar conditions:
- Left Eye (Super Sizer Fibers Mascara): Applied as directed. Despite initial application giving some volume, my lashes began to lose their curl almost immediately. Within 10 seconds, the curl was noticeably drooping, and by the end of the day, my lashes had straightened out completely.
- Right Eye (Super Sizer Waterproof Mascara): Applied in the same manner. This mascara held my curl throughout the day without any noticeable drooping. My lashes stayed lifted and maintained their curl much better compared to the fiber version.
Detailed Analysis

Curl Hold
- Super Sizer Fibers Mascara: Did not maintain the curl well. The built-in fibers, while adding some length, seemed to weigh down my lashes. This led to a loss of curl within seconds of application. If you have straight or stubborn lashes that require extra support to hold a curl, this mascara might not be suitable.
- Super Sizer Waterproof Mascara: Excelled at holding the curl. Its waterproof formula is likely a contributing factor, as it offers better support and resistance to drooping. For those with straight lashes, this mascara is more effective at keeping curls intact throughout the day.
Volume and Length
- Super Sizer Fibers Mascara: Provides additional length due to the fibers, which can create a false-lash effect. This mascara is designed to give the appearance of longer and darker lashes. However, the increased length comes at the cost of curl hold.
- Super Sizer Waterproof Mascara: Delivers impressive volume and some length, but its primary strength is in maintaining the curl. While it does not add as much length as the fiber version, it offers a more balanced performance in terms of volume and curl retention.
Wear and Removal
- Super Sizer Fibers Mascara: Like most fiber mascaras, it may require more careful removal to avoid fibers falling into your eyes. It is not waterproof, so it may smudge or run if exposed to water.
- Super Sizer Waterproof Mascara: Designed to withstand water and sweat, making it ideal for long days or humid conditions. It removes easily with oil-based makeup removers, which can be convenient for evening routines.
Conclusion
For those with straight lashes who need a mascara that will hold curls throughout the day, the CoverGirl Super Sizer Waterproof Mascara is the superior choice. Despite their similar appearance and claims of providing 400% more volume, the fiber version did not maintain my lash curls and caused them to droop quickly. The waterproof version, on the other hand, provided excellent curl retention and overall performance.
If you’re looking for a mascara that offers both volume and long-lasting curl, stick with the waterproof option. The fiber mascara may be worth a try if you’re interested in added length, but it may not provide the same level of curl support.
