Hello, Welcome to healthcare magic. The dark colour of lips in a non smoker could be familial. It is also common in individuals who have a dark complexion. It is difficult to lighten the inherent colour of your lips. You could use a sunscreen in the morning and afternoon and a moisturiser containing elovera at bedtime. Q switched Nd- Yag laser is also being used recently but with variable results. The possibilities of the dark spots on your nose could be melasma, freckles, lentigenes and lichen plan us pigmentosus. Use a broad spectrum sunscreen every 4 hours. Use a lightening agent containing 2% kojic acid, arbutin, liquorice and niacinamide at bedtime for 2-3 months. The cream which you have mentioned does not seem to have any steroid or harsh ingredients. It seems to have natural extracts for skin lightening . But since it is not a prescription drug , I cannot give you any medical evidence about its efficacy. Hope this helps you. Take care.
