What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, Paula's Choice C15 Super Booster is one of the more polarizing picks in this roundup. On the positive side, byrdie.com's hands-on review reports smoother-feeling skin texture after consistent use, a high-trust r/SkincareAddiction review calls it a holy-grail product after two months of consistent application with healthy, glowy results, and beautifulwithbrains.com names it a favorite for brightening and wrinkle prevention. On the negative side, a separate high-trust r/SkincareAddiction post titled "regret buying Paula's Choice 15% Vitamin C" reports it did nothing for the user despite the price, and an r/AusSkincare commenter describes a strong metallic smell and a burning sensation on application.
What reviewers liked
- byrdie.com's verified-tier review reports smoother skin texture after consistent use
- 15% L-ascorbic acid plus vitamin E and ferulic acid in a flexible booster format
- r/SkincareAddiction long-term users include strong holy-grail endorsements

Where it falls short
- A high-trust r/SkincareAddiction "regret buying" thread reports no visible results despite the price
- Reviewers describe a strong metallic smell and stinging on application
- 4.2 Amazon average across 3,143 reviews reflects genuinely mixed user experiences
- Booster format makes dosing easy to overdo, per community feedback
- Price per ounce is high relative to comparable LAA formulas in this roundup
Across the reviewers we read, Paula's Choice C15 Super Booster is one of the more polarizing picks in this roundup. On the positive side, byrdie.com's hands-on review reports smoother-feeling skin texture after consistent use, a high-trust r/SkincareAddiction review calls it a holy-grail product after two months of consistent application with healthy, glowy results, and beautifulwithbrains.com names it a favorite for brightening and wrinkle prevention.
On the negative side, a separate high-trust r/SkincareAddiction post titled "regret buying Paula's Choice 15% Vitamin C" reports it did nothing for the user despite the price, and an r/AusSkincare commenter describes a strong metallic smell and a burning sensation on application. A third high-trust thread documents an unexpected result from a half-face test. The 4.2 average across 3,143 Amazon reviews lines up with that split: it works strikingly well for some users and produces underwhelming results for others, which is a pattern common to high-percentage LAA formulas where pH, skin barrier state, and consistency all influence outcomes.
The booster format (designed to be mixed into existing moisturizer or used neat) is the differentiator. It's a useful pick for users who want LAA flexibility without committing to a standalone serum, but expectations should be calibrated to a hit-or-miss community track record.

Very strong smelling, kind of like metal, liquid so it's easy to use too much. It gave me that burning feeling on my skin but most Vitamin C ...
The product did absolutely nothing for me, I recall I had to spend somewhere around $60 for the small vial. Considering the price tag I was very careful.
