I’ve been using ZO or Obagi for a while now. Can you recommend a good day/ night regime for an over 70-year-old? I had regular Hydrafacials in the past as well as Aqua 3, Profhilo and Skinpen treatments. Love all your advice, thank you.

Hi, I’d stick with the ZO/ Obagi products – they are all really good. If you feel they aren’t doing what you’d like for your skin, ask whoever is supplying them to you to tweak your regime.
