- Question: I purchased skin medica Lycra and TNS Serum ... Are use both in the morning and at night. Can I add, or should I add, skin medica retinol (2-4 times a week) and vitamin C daily? Would this be over kill? I’m 37 and looking for overall better complexion, to keep wrinkles at bay and brighten skin.
Thank you for reaching out to us . I would recommend SkinMedica`s Age DefenseRetinol Complex .25 for night, possibly once or twice a week. I would follow with a moisturizer .Stay with the TNS and the Lycra products for day or on the night`s that you do not use your Retinol.Hoppe this helps, have a nice day !
