There are many tools on the market for face washing; brushes, cloths, even rubber devices that claim to be superior. Are any of these gadgets necessary to get clean skin?
The answer depends on your skin type and what you are trying to cleanse at the end of the day; makeup, excess oil, debris, layers of sunscreen.
If you need an extra boost in your daily cleansing routine, consider your habits. Are you willing to keep a gadget charged (or replace the batteries on a regular basis)? Can you commit to changing brush heads when they wear out? All gadgets require maintenance to work properly so investigate before you invest!
The most basic way to get an extra hand cleansing your face is a simple washcloth. Have a few on hand so you can launder them regularly to keep bacteria from growing.
Be gentle when using any tool. Use soft brush heads and light pressure. Applying too much pressure can lead to broken capillaries and other long term damage.
Most importantly, wash your face twice a day!
