Best Ingredients for Dryness
Dryness is a barrier problem — either the skin isn't holding onto water, or it isn't making enough of its own lipids to seal that water in. Humectants pull water in; barrier lipids keep it there.
Where to start, if you're new to this
Of the 18 ingredients below, Hyaluronic Acid is the gentlest starting point — it's rated the lowest risk tier here and can be used at full frequency from day one, no ramp-up needed. That's not the same as "most effective" — it's the one least likely to need troubleshooting while you're still learning how your skin responds.
How these differ
These aren't interchangeable — they group into 6 real mechanism classes, and which one fits depends on what else is already in a routine.

Questions people ask
Usually two is enough. Skinzy's own routine builder caps a full routine at 4 steps across every concern combined, so stacking more than two for a single axis tends to crowd out something else your skin needs.
Most of them, yes — but a few specific pairs genuinely conflict. Check the "don't combine with" section on each ingredient's own page before combining two you're unsure about.
