It is possible that you are experiencing a temporary increase in acne breakouts while using Biacna. This can happen for various reasons such as diet, stress, fatigue, or other products you may be using on your face. If this breakout lasts for more than 2 weeks or if you have not seen any improvement after 4 weeks of treatment, it would be a good idea to speak with your pharmacist or doctor about potential alternatives or additional treatments. It is important to communicate any concerns or changes in your condition during the treatment process to ensure the best outcome for your skin.
