Bye Bye Blemish is an acne drying lotion containing sulfur and salicylic acid. It is very similar to the Serious Skin Care Dry-Lo and the Mario Badescu drying lotion at less than half the price. I found mine at Fred Meyer for $8.99. You can purchase it at Ulta or many online retailers for under ten dollars.
It is very important not to shake the bottle and mix the ingredients. This will cause the product to dry up very quickly. Instead, stick a q-tip into the bottle as far down as you can and pull it out and apply to the areas needed. Be careful not to get too close to your eyes because the fumes will sting the eyes. I apply this before I go to bed on my blemish areas. I often cover whole areas of my face that are broken out. In the mornings wash it off with your daily face wash.
The Bye Bye blemish works just as effectively as the higher priced products, but won't break the bank. It also helps that you can find it locally without having to order online.
