Dry vs. dehydrated: the key difference
Dry skin = lacking oil (lipids) → needs richer creams/occlusives.
Dehydrated skin = lacking water → needs humectants (hyaluronic acid, beta-glucan, panthenol, glycerin).
If you only apply cream, you might be treating oil loss while your skin is actually thirsty for water.
The 4 most common mistakes
Skipping a hydrating serum – Without humectants, your cream sits on top and tightness returns.
Over-cleansing or hot water – Strips your barrier and increases transepidermal water loss.
Overusing actives – Retinoids/acids help long-term but can create short-term dryness. Buffer or alternate nights.
Environment – AC, planes, cold or dry seasons pull water out of skin. Add humidity and reapply hydration.
A simple 4-step fix (AM & PM)
Gentle cleanse – Choose a non-stripping cleanser.
Hydrating serum (on damp skin) – 1–2 pumps of HA/beta-glucan/panthenol.
Ceramide moisturizer – Locks hydration and supports the barrier.
Optional occlusive at night – A thin layer of petrolatum on flaky spots to seal everything in.

Final tip
Apply serum and moisturizer to slightly damp skin. With this order, the guesswork ends—and that “still dry after moisturizing” feeling finally fades.
