Hi Sangdoo!
In 7 days.....? Well that's not much time, but here are some
natural things that could help you get started:
Likas Papaya Soap
Black African Soap
Salicylic Acid (aspirin) mask
Some ppl have luck with turmeric powder products topically.
Please let us know if any of these things work for you.
Good luck and welcome!
