I am 27 yrs old and I have been using Tamanu oil for just 10 days now and I love it. I apply it after each time I wash my face. My skin became clearer and radiant within 7 days. I dont need any makeup anymore and I completely stopped using Retin A. It doesnt break me out at all. I love this oil and I have added it to my essentials. I think it is esp good for dark circles too.
