Thank you for your question. If you are already using a good retinoid in your night cream, that product is already speeding up your skin cell turn over and keeping the epidermis nice and compact. I therefore would not advise the use of a exfoliating device on top of that, as this could cause excessive exfoliation which comes with its own set of problems. It may result in sensitivity or inflammation which will in turn cause pigmentation and this is not a good outcome at all. So I would not advise this. If you really want a deeper exfoliation, rather have a peel that is compatible with the products you are using, and make sure you follow the correct prepping procedure to stop your retinoids in time and then re-introduce them slowly again after your treatment as per the protocol for the peeling procedure (which your therapist or doctor needs to explain to you). If you would like some more advice or consider some peel options, have a look on www.skinrenewal.co.za.
