The time it takes for each person to see results is different. Some people will see results much faster than others, while some may have to wait a little bit longer. But tests done by the Kerassentials team show that you might not see results for 9–12 weeks.
This is just a guess, not a general rule. Some people may notice a change before the time that is given. If you can, order the 90-day supply of three bottles. This will give you a better chance to try it out.
