## Customer Reviews

### ⭐⭐⭐⭐⭐ Good
*by S***E on 6 July 2026*

100% good little drops works wonders

### ⭐⭐⭐⭐⭐ It works
*by S***K on 29 June 2026*

Improvement is visible within few weeks. I was sceptical about buying it. However I guess I made right decision.

### ⭐⭐⭐⭐ Good serum, hasn’t broken me out, slow results
*by B***L on 10 December 2025*

So far so good, nice consistency, not too runny or sticky. Cloudy serum which has helped to brighten skin over the last 2 weeks. Works well with microneedling, didn’t cause too much irritation. Also hasn’t broken me out or caused any reactions even though I have acne-prone skin. 4 stars because results are very slow…. Hasn’t brightened as much as I would’ve hoped over the last 2 weeks, will see if using for a month makes a difference.
