What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Contains 15% ascorbic acid with vitamin E and ferulic acid in a well-balanced, pH-appropriate formula under 3.5
- Brightens skin and creates a luminous, plumper appearance without excessive greasiness
- Absorbs quickly and layers well with other products, including gel moisturizers and sunscreen
Reviewers push back
- Dropper bottle packaging exposes the serum to air and light, causing oxidation over time
- Does not minimize breakouts or address acne concerns
- Price point is high for a product in non-airless packaging
A well-formulated 15% vitamin C serum with vitamin E and ferulic acid that brightens and plumps skin, though the dropper bottle allows oxidation and it does not address acne.
