Benefits of dry brushing
“Dry brushing unclogs pores in the exfoliation process. It also helps detoxify your skin by increasing blood circulation and promoting lymph flow/drainage,” says Dr. Khetarpal. Also, by unclogging pores, it's easier for the body to sweat and eliminate toxins in your system.
How Often Should You Dry Brush?
Since dry brushing can leave your skin feeling a little, shall we say, raw (it is total-body exfoliation, after all), it's up to you (and the strength of your skin) to decide how often to do it. As a general rule of thumb, It recommends dry brushing no more than one to two times per week. And don't forget to wash your brush with baby shampoo at least twice a month to get rid of all of that dead skin buildup.
If you have ultra-sensitive skin, try dry brushing once every couple of weeks. If you build up a tolerance to it successfully, then transition to one to two times a week.
Are There Risks to Dry Brushing?
In general, exfoliation should be done with caution. If your skin skews extra sensitive or you're struggling with eczema, psoriasis, or other serous skin conditions, steer clear of dry brushing as it can exacerbate your issues and cause further irritation.1 Also, brushing too hard, too often can lead to irritated skin. While you'll notice your skin will redden after dry brushing, skin abrasions aren't the results to expect. Lastly, if you have an open wound on your skin, avoid this area to avoid introducing bacteria and infection.
Post-dry brushing, be sure to take a shower to rinse off all the dead skin cells. And if you plan on heading out for the day, it advises using sunscreen, as the process can make your skin more sensitive to the sun.
