User Feedback Patterns
Users consistently report visible brightening and improved skin tone within 2-4 weeks. The 15% concentration is effective for most users.
At $55 for 20ml, this is one of the priciest vitamin C serums relative to volume. Users note the small bottle size is a drawback for daily full-face use.
Multiple reviewers report receiving bottles that appear already oxidized (yellow or orange). This is a recurring complaint that the brand has acknowledged.
The booster format is praised for flexibility. Users mix it with moisturizer, sunscreen, or other serums without issues.
Multiple users note this formula does not ball up under other products or makeup, unlike some competing niacinamide serums.
Users with dry or combination skin report this feels more hydrating than pure niacinamide serums with zinc, likely due to the squalane, HA, and lack of zinc.
The squeeze bottle with press-down cap makes it difficult to control how much product dispenses. Some users report buildup around the opening.
Consistent feedback about reduced pore appearance within 2-4 weeks of daily use.
Which Should You Buy?
The Inkey List Niacinamide Oil Control Serum offers great value at a lower price point. Paula's Choice C15 Super Booster may be worth the premium if you want 15% L-Ascorbic Acid.
