I have been using this cream for 3 years and I am 35 years old. At the age of 32, I developed acne on my chin and neck. All three dermatologists I visited recommended treatment with pills, which I did not want. Eventually, a friend recommended Ac-Norm Type 1 to me, and in combination with La Roche's Effaclar facial cleanser, I saw results from the first week. Within a month, the pimples were gone. I used it morning and night with proper cleansing before for a year. Now I only wear it during the day for prevention, and at night I use something more suitable for my age. It worked 100% for me, as you can see in the photo of my face. Once, this area was full of internal and surface pimples.
As for the packaging, it is a bit inconvenient because when the applicator doesn't dispense any more cream and it appears to be finished, if you manage to open it, there is enough cream inside for another week.
Other than that, it is an excellent product for me and I recommend it. (Skin type: Combination)
