Choose the right razor
Choosing the right razor is very important. The razor that you use should be sharp, so that a cleaner shave is ensured. Dull razors can damage the skin, especially when you have acne. Moreover, try not to re-use a razor more than twice if you are shaving skin with acne.
Soften your skin
Before you start shaving, wash your face with warm water to soften the hair and skin. This will result in lower resistance to the razor and lesser chances of damaging or irritating your skin.
Use products that are acne friendly
Another important thing is to use products that are suited to your skin type. You should be using a non-alcoholic shaving cream or gel, as it will not irritate your skin during the shave. Moreover, shaving oil is essential, giving your skin extra protection after you have shaved.
You should shave lightly and very carefully. Make sure you do not cut open any acne bumps. Open acne may cause an infection on your skin and increase the chances of more outbreaks. Shave in a downward motion and apply little pressure. In this case, the sharper your razor is, the less force you will need to use.
