Phytoceramides (Oral or Topical)
Plant-derived ceramides — the lipid building blocks of skin's barrier layer. Oral phytoceramides (from wheat or rice) improve skin hydration from within; topical ceramides reinforce barrier from without.
Moderate evidence for oral phytoceramides improving skin hydration and elasticity (Ceramosides trials). Strong evidence for topical ceramides in barrier repair, atopic dermatitis, and dry skin. Effects: 4–12 weeks.
Ceramides are the lipid mortar between skin cells that lock moisture in and keep irritants out. Levels decline with age and in conditions like eczema and atopic dermatitis. Phytoceramides — derived from wheat or rice — are structurally similar enough that the body uses them to rebuild ceramide content in skin. Oral phytoceramide RCTs show measurable improvements in skin hydration, smoothness, and barrier function (Ceramosides is the well-studied form). Topical ceramides are now in nearly every barrier-repair moisturiser (CeraVe leads the category).
