Moisturisers usually contain three types of ingredient. Humectants (e.g. glycerin, hyaluronic acid) attract and bind water. Emollients (e.g. skin-identical lipids) soften and smooth the surface. Occlusives form a layer that slows moisture loss.
A good moisturiser balances all three. Barrier-friendly care favours ingredients compatible with the skin's own lipids over heavy foreign occlusives like mineral oil.
Zeitschild's skin-identical lipids approach follows this: slowing moisture loss without clogging the barrier, using ingredients suited to the skin's natural structure. Consult a physician for a moisturiser texture suited to you.
