I had tried several different creams and lotions, but they either didn’t work at all, or the results were only temporary. I was beginning to lose hope and had given up on ever finding a solution. After use: I started using Zakdavi™ Acanthosis Nigricans Therapy Oil on my dark knuckles, and I can’t believe the difference it has made! After just a few weeks of using the oil twice a day, my knuckles have significantly lightened, and the patches are barely visible. The oil is easy to apply and absorbs quickly, leaving no greasy residue. My knuckles feel smoother and look brighter than ever before. I’m so grateful to have found this product, and I can’t recommend it enough! Step 1: Cleanse the affected area with a gentle cleanser and pat it dry. Step 2: Shake the bottle well before use. Step 3: Apply a few drops of the oil onto your fingertips. Step 4: Gently massage the oil onto the affected area in circular motions. Step 5: Allow the oil to be absorbed into the skin before dressing. Step 6: Use the oil twice daily, once in the morning and once at night, for best results.
