- Question: At night I use TNS, Retinol and HA5. In what order should I apply after cleansing?
Thank you for reaching out to us. I would recommend using the TNS with your HA5 for day and the Retinol with your HA5 @ night . On the nights that you do not use your Retinol just apply your TNS with your HA5.
Hope this helps, have a nice day !
