Recalling the condition of my skin in the past...specifically occasions when I had, no jokes, FLAWLESS skin. One time was when I was having salty baths EVERY day(post drumming/exercise). Another time was when my regular moisturiser was aqueous cream (uses mineral oil rather than based on natural oils).
As OP suggests, an inside out approach is best for overall health.
A couple of posts saying they've reacted badly- prob not letting it soak in long enough or not rinsing well enough.
Stick with it people and the best!! Loves!!
