Most people see that their skin is already improving at the first check in. Some people do not until the 2nd check in. In terms of "real progress" that really depends on the person....by the end of the 3rd month most people should be about 75% clear.
Everyone's skin and body are different. Certain types of acne, such as non-inflamed acne, can take longer to treat and go thru more fluctuations as the products push the blockage up to the surface. The body can inflame non-inflamed acne, so the skin can get worse before it gets better.
Photos submitted in the program are a great way to help the clients see progress, as they often feel they are not making progress or may mark their skin as 'worse'.
