My face has been tanned more compared to my body. I started using lomela cream. I used for like 15 days. I can see my dark pigmentation in my skin is reducing. I have slight irritation when I wash my face. What should I do for it? And how long can I use it? When to stop? In what intervals should I use the cream like daily or weekly twice or thrice? And I use biotic sunscreen in the day time when I go out. On applying it I have a burning feel for like 5 minutes. After that I feel normal. Should I change my sunscreen? What kind of soap do you recommend me to use?
