I've gone through many jars of this and consider this my faithful partner in combatting acne. It helps minimize active pimples and expedites the healing process. I always have multiple jars as backup.
I've gone through a few bottles of this ampoule and I likely won't repurchase going forward. I'm not sure if it does anything for my skin anymore now that I stopped using tret. Before, it did a nice job in soothing some of the irritations from tret and reduced some redness.
