Dairy Sphingomyelin Trial Shows Skin Hydration Gain in Healthy Adults
By Nutranexa News |
A 12-week placebo-controlled study in Japan reported higher upper-arm skin hydration after daily dairy-derived sphingomyelin in healthy women.
Trial Setup
The randomized, double-blind, placebo-controlled study enrolled healthy women aged 30 to 59 years in Japan.
Participants received either a dairy-derived sphingomyelin tablet providing 23.6 mg/day or placebo for 12 weeks, with skin hydration and transepidermal water loss used as primary measures.
What Changed
Among the analyzed participants, the increase in upper-arm skin hydration was greater in the sphingomyelin group than in the placebo group at the end of the intervention.
The study did not find significant between-group differences in transepidermal water loss or subjective hydration perception, and it reported no adverse drug reactions.
Buyer Takeaway
For dairy-lipid and sphingomyelin suppliers, the paper adds another use-case angle outside infant nutrition and cardiometabolic positioning.
The effect reported was specific and limited, so developers will still need to separate measured hydration outcomes from broader beauty or skin-health marketing claims.
