A spice from India called turmeric can be helpful with acne problems and acne scars
Simply mix turmeric and lemon juice. Make a paste out of it and apply it to your face. Leave it on for 15 min and wash off. If you did it correctly your face should have a smooth soft feel to it afterwards. Your face may look a bit yellow after but if you wash your face very well after and wash it when u wake up in the morning it should look normal
For acne scars mix turmeric and water together and apply on problem area for 15 min. Like the acne mixture it will make your face a bit yellow so be sure to thoroughly wash.
I have been using it for about a month or two now. I've had acne since I was 10 and the scars that have been there for years are finally starting to look better! I highly recommend it even though your face may be a bit yellow for a little bit. I also recommend doing it before you go to sleep so your skin will have a chance to be not so yellow.
