([Clinical, Cosmetic and Investigational Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/30858720/))

## What reviewers say

Users consistently describe this toner as a "facial in a bottle" specifically suited for mature, dry, or "devitalized" skin due to its vitamin-enriched formula.

- Liked: Smoother texture (often mentioned)
- Disliked: High price point (often mentioned)

### What does Gluconolactone do for skin with dark spots?

Gluconolactone helps improve skin with dark spots by providing gentle smoothing and renewing benefits that make the skin tone more even and bright. This ingredient is well tolerated by sensitive skin while supporting skin rejuvenation.
Sources: [Cutis, 2004](https://pubmed.ncbi.nlm.nih.gov/15002656/)

You can use this toner with retinol by applying the toner first in your routine and following it with retinol, though it is best to alternate nights or use them at different times of day to keep your skin calm and smooth.
