This product it's good. I feel like if I go without it for a day or two, I start breaking out again. It did took a while to see a difference on my skin. I would say like 2-3 weeks but it definitely does work. I'm down to my last drop so I'll be ordering more. I was disappointed at first when I received the bottle because it's so small but it did last me throughout the entire month. Overall I recommend.
Excellent serum!! This was amazing. My 15 year old son uses this as he has acne on his forehead. After using this for just 5 days he has noticed clear skin and softer complexion. I am his mom and I use it to and this is the best stuff. Better than prescription medicine for acne at least we experienced it for our selves. Very much worth the price I paid
