Repeat purchase loyalty

High repurchase rate in reviews. Users describe it as a staple they consistently return to.

Timeless
Effective and affordable CE Ferulic

Reddit favorite

Consistently ranked among the top vitamin C serums on Reddit. r/SkincareAddiction and r/30PlusSkinCare frequently recommend it as the best value CE Ferulic serum.

Oxidation is the main complaint

Users report the serum darkening within 4-8 weeks, sometimes faster in warm climates. Several recommend buying smaller sizes and refrigerating immediately.

Stinging on initial use

The 20% concentration causes noticeable stinging for most users during the first 1-2 weeks. This typically subsides as skin adjusts.
