"i applied duac on my face as instructed and after 2 days of using it, i noticed that my pimples started to disappear but the problem is my whole face got swollen, itchy and red. i can&#039;t even sleep and go to school for days. so what i did is i visited my doctor again and told me that those were the side effects of the product and told me to stop using it. to relieve the stinging and redness i used an ice pack on my face and put moisturizer non stop. luckily, after a few days the swelling and redness disappeared. thank god my acne disappeared and since then whenever pimples appear on my face, i just applied the gel directly on the pimples."
