Benefits
Wrinkle score improved about one grade in a 12 week trial
In a randomized double blind placebo controlled trial in 64 women aged 45 to 60 (Boisnic 2019, PMID 31033133), 12 weeks of oral polar lipids from wheat extract oil improved facial wrinkle score by about one grade on the Lemperle scale versus placebo, along with facial hydration and skin roughness. The trial was funded by Robertet, which manufactures this ingredient, and the published paper never names ceratiq. The widely quoted 88% response rate does not appear in any published study cited here, and neither does the claim that wrinkles improved about three times more than placebo. Both should be treated as unpublished company marketing.
Skin hydration measured after 12 weeks or 3 months
No cited study reports a 4 week result. In 51 women with dry skin, 350 mg a day of wheat extract oil for 3 months increased corneometer hydration versus placebo on the arms and legs (Hitex funded, 2011). In 64 women over 12 weeks, facial hydration improved versus placebo (Robertet funded, 2019). A third trial in 72 women over 56 days was run by a different company, Seppic, on its own competing wheat lipid product, and its authors noted the benefit did not last once people stopped taking it. The idea that swallowed phytoceramides rebuild the skin barrier is a proposed explanation, not something these trials measured.
Hydration measured on both face and body skin
The cited trials measured hydration, skin roughness and wrinkle scores. They did not report elasticity, suppleness or radiance, so those specific claims are not supported by the studies on this page. What the trials do show is improved corneometer hydration on body skin, the arms and legs, in the 2011 study and on facial skin in the 2019 study. The lipid matrix explanation is a theory about how that might work, not something the trials tested.
The 95% satisfaction figure is unpublished
The 95% figure does not appear in any published study cited on this page, and no cited trial used a 200 mg dose. The study the page points to, published as a moisturizing trial of a wheat extract food supplement, gave 51 women with dry skin 350 mg a day for 3 months and reported corneometer hydration readings, not a satisfaction percentage. Treat the 95% claim as unpublished supplier marketing rather than a research finding.
Laboratory UVB findings, not human evidence
This is laboratory work in cells and mice, not a human result, and the animal and cell studies described here are not among the references listed on this page, so a reader cannot check them. The closest published data is from the 2019 trial, which separately exposed donated human skin samples to UV light in the lab and found more collagen in those samples. Lab and animal findings often fail to repeat in people. Nothing here shows that taking this ingredient protects your skin from sun damage, and it is not a substitute for sunscreen.
Vegan, non-GMO source vs animal-derived ceramides
Wheat phytoceramides are a plant based option for people who avoid animal derived ceramides. They are similar in structure to human skin ceramides but not identical, and no cited study compared a plant source against an animal source. Because the source is wheat, this ingredient is not appropriate for anyone with celiac disease or a wheat allergy unless the finished product carries gluten free certification.
Mechanism of action
Topping up ceramides that decline with age (proposed)
Ceramides make up a large share of the fatty matrix that helps skin hold water, and skin ceramide levels fall with age, which is one reason skin gets drier. The idea that swallowed plant ceramides travel to the skin and rebuild that matrix is a proposed explanation. None of the cited trials measured skin ceramide levels, so this remains a theory rather than a demonstrated mechanism.
Skin barrier reconstruction
The suggested mechanism is that phytoceramides reach the outer skin layer and help it hold water. The cited trials measured skin hydration with a corneometer but did not measure skin barrier lipids or water loss through the skin, so this pathway has not been confirmed in people. Nothing in the published data supports an immediate or fast acting effect.
Collagen synthesis support (preclinical)
In laboratory work, wheat extract oil has been linked to collagen production, and the 2019 trial reported more collagen in UV exposed pieces of donated human skin tested in the lab. That is not the same as more collagen in a living person's skin, and the cited trials did not measure collagen in participants. Whether collagen has anything to do with the wrinkle score change seen in that one trial is unknown.
Lipid matrix repair
Aging skin loses ceramides and some of the organization of its lipid matrix. Whether oral phytoceramides help reorganize that structure has never been tested in the cited studies, so this is speculation rather than a measured effect, and it does not explain anything that the trials actually reported.
Clinical trials
Randomized double blind placebo controlled trial in 64 women aged 45 to 60, running 12 weeks with an 8 week follow up, testing oral polar lipids from wheat extract oil. Funded by Robertet, the company that manufactures this ingredient, and the published paper does not use the name ceratiq. The dose is not stated in the published abstract. J Cosmet Dermatol 2019, PMID 31033133.
64 women aged 45 to 60 with signs of skin aging. 12 weeks of supplementation plus an 8 week follow up.
Facial wrinkle score improved by about one grade on the Lemperle scale at week 12 versus placebo, and facial hydration improved as well. A separate part of the study exposed donated human skin samples to UV light in the laboratory and found more collagen, which is a lab result and not a measurement in participants. The quoted 88% response rate and the 8 week p<0.001 figure do not appear in the published paper. This is one small manufacturer funded trial and the result needs independent confirmation.
Randomized double blind placebo controlled trial in 51 women with dry skin, published as The moisturizing effect of a wheat extract food supplement on women's skin, Int J Cosmet Sci 2011, PMID 20646083. The dose was 350 mg a day of wheat extract oil for 3 months, not 200 mg, and the paper does not name ceratiq. The study was funded by Hitex.
51 women with dry skin, treated for 3 months.
Corneometer skin hydration increased significantly versus placebo on the arms (p less than 0.001) and on the legs (p equals 0.012). The claim that 95% of participants reported dramatic improvement does not appear in the published paper, and no cited trial tested a 200 mg dose. With 51 participants, a single 3 month run and industry funding, this is a small study.
Cell culture and mouse work on wheat extract oil and UVB damage, described as a conference poster presented at the American Society for Nutrition. A poster is not a peer reviewed publication, and this work is not among the references listed on this page, so readers have no way to check it.
Not applicable — cell culture (human keratinocytes) and animal (hairless mice) studies.
The reported result is that wheat extract oil reduced UVB damage markers in cultured human skin cells and in hairless mice. Animal and cell results frequently do not carry over to people. No human study has tested this ingredient for sun protection, this work does not explain the wrinkle score change seen in the 2019 trial, and nothing here is a reason to use less sunscreen.
