Yes, saffron helps in whitening skin tone to some extent. It is due to the active compounds in saffron like crocin that help reduce hyperpigmentation from the skin. Some studies also suggest that saffron can reduce melanin production in the skin. You can either apply saffron soaked in milk directly to your face or drink it daily for better results. However, consult a doctor before oral consumption if you have a medical condition or are on blood thinners.
