Have been using The Unplugged Serum for my uneven skin tone around my mouth area. Its been 3 weeks and I can see some positive results. I can myself feel the area lighten a bit. I even have before and after pics that I sent to the team. I am looking forward to keep using this product and treat my hyperpigmentation. One thing that I would like to put forward is that their team is very proactive in responding. They told me the reasons for hyperpigmentation, how to treat it according to the lifestyle that I live, even some eating tips and of course this product. They do not spam. They send relevant tips once a week to reduce hyperpigmentation. I am totally in love with this brand.
