I was using coconut oil for my baby girl for two months...it did not darken the skin..i then used olive oil , but found it makes the skin very dry...i researched and found it was true...atleast in climate of india, it didnt seem to be good... Almond oil is really good , made her skin much softer... But right now again moved back to coconut oil as my mom didnt feel good about using almond oil...
PS; I advice you not to keep changing the oil for babies as i did..........
If you using coconut oil, continue using it....atleast for an year or two ....There is no darkening happening...Coconut oil is best
Almond oil is also very good and if you had started with it first , i would tell you to continue with it..
