Been using Dose- Alpha Arbutin2% & kojic acid 1% for nearly a year now. I bought it because I had problems with hyperpigmentation. I’m now on my 4th bottle and can certainly see the results. Although the serum hasn’t completely clearly the pigmentation but it is fading. I see them but observers can’t. For a lady of nearly 70 years of age, my skin looks brilliant, no wrinkle at all. I can certainly say with confidence, the serum works. I have also been using Fulvic travel pack of shampoo, conditioner and Mist. Due to age, my hair had started shedding but a year later, it’s grown back. It is still growing this Summer but would like to see how it behaves in Winter because my hair sheds off in Winter. The thing is this travel set has helped stop itchiness and dandruff. When I comb it, there are no loose hairs on the comb. My daughter has been amazed so much that she is going to buy the Fulvic hair set. I am moving into buying the big sizes because this works. Thank you VH for giving us such brilliant products. I must also advise anyone trying these products to persevere. One time use won’t give you the results. You have to keep on and in the end, your efforts will be rewarded.
