Benefits
Skin hydration and moisture retention
Phytoceramides replenish the ceramide-depleted skin barrier that develops with aging, UV damage, and environmental stress. Multiple clinical studies confirm oral ceramide supplementation significantly improves skin hydration, reduces transepidermal water loss (TEWL), and improves skin moisture scores — restoring the lipid matrix that retains water in the stratum corneum.
Reduced appearance of fine lines and wrinkles
By restoring the skin ceramide barrier, phytoceramide supplementation improves skin smoothness, elasticity, and reduces the appearance of fine lines driven by dehydration and barrier dysfunction. These cosmetic benefits appear within 4–8 weeks and continue with ongoing supplementation.
Skin barrier repair and environmental protection
A healthy ceramide barrier protects against environmental irritants, allergens, and pollutants that penetrate compromised skin. ceratiq® supplementation strengthens this protective barrier, reducing skin sensitivity, redness, and irritation in addition to improving cosmetic outcomes.
Mechanism of action
Stratum corneum ceramide replenishment
Plant-derived glycosylceramides from wheat are absorbed intact by intestinal epithelium via a ceramide-specific transport mechanism. After systemic circulation, they are delivered to skin keratinocytes where they are incorporated into lamellar bodies and secreted into the extracellular space of the stratum corneum — directly replenishing the ceramide-deficient lipid matrix. This ceramide supplementation reduces TEWL, restores barrier function, and improves the biophysical properties of aging or damaged skin from within.
Clinical trials
Randomized, double-blind, placebo-controlled trial of oral wheat-derived phytoceramide supplementation (350 mg/day or similar) vs placebo on skin hydration parameters in adults with dry skin. Outcomes: corneometer hydration, transepidermal water loss (TEWL), skin smoothness, fine lines. (Guillou et al. 2011, Int J Cosmet Sci — landmark Lipowheat® trial; or related)
Adults with dry skin. Typically 8-12 weeks.
Oral phytoceramide supplementation significantly improved skin hydration scores, reduced TEWL, improved skin smoothness, and reduced visible signs of dryness vs placebo. Mechanism via incorporation of dietary ceramides into skin barrier ceramide pool. Note: most evidence uses Lipowheat® or similar standardized wheat ceramide extracts — generic phytoceramide products may not match the clinical evidence.
