Il siero è ottimo per schiarire le macchie. Dopo qualche settimana, noto un miglioramento chiaro nel tono della pelle.

Best whitening serum for sensitive skin
My skin is very sensitive and is prone to breakouts if there is any trace of harsh ingredients. This serum however did a great job of brightening and whitening my skin while also hydrating my skin without any sensitization. It also has a subtle rose scent which smells nice.
