Hello, Welcome to healthcare magic Your complexion is usually decided at the time you are born. No treatments can make a person fairer than their original color. In your case you had fairer skin when you were younger, so there is scope for improvement. Sun protection is the key to a lighter skin. As much as possible avoid direct sunlight, wear a sunscreen with an spf of at least 15 every day in the morning half an hour before you go out an re apply it every 3-4 hours. You can use a face wash containing Glycolic acid twice a day. Lightening creams like kojic acid and or vitamin c serums will help. You can go for a cosmetology consultation and cosmetic services like chemical peels can be tried. Even mesotherapy with vitamin c and or glutathione will help. Drink plenty of water, eat fruits rich in vitamin A and C. Hope this helped Take care
