My goal is Fitzpatrick shade 3. I want to at least get to shade 4. I think I’m currently close to Nina Davuluri’s skintone (1st pic) and I want to at least get to Frieda Pinto’s skin tone (2nd pic). I was the right shade or slightly darker 5 years ago but I got super tanned on vacation and I haven’t been able to fade it. I’m currently using tretinoin .05% face and body everyday for exfoliation and skin cell turnover. For supplements I’m using nac 2000mg vit c 2400mg, astaxanthin 8 mg, pycnogenol 100mg. And I’m planning on using nadinola hydroquinone cream for 10 days every 2 months and alpha arbutin and licorice extract in between to prevent collagen loss. Also using spf a lot and staying out of the sun. Is there anything else I should do? Is my goal achievable in 1 year?
