Sea Buckthorn for Skin Health

Finding: Both pulp oil (p<0.01) and paraffin oil placebo (p<0.001) groups improved symptomatically; seed oil group did not reach significance (p=0.11). No clear advantage of sea buckthorn over paraffin placebo for dermatitis symptoms; pulp oil did raise HDL (1.38 to 1.53 mmol/L). Yang B is lead author (commonly mis-cited as Yang 2014; PubMed indexed 2004).

Finding: Seed oil slightly increased docosapentaenoic acid (DPA) and decreased palmitic acid in skin glycerophospholipids; pulp oil increased palmitoleic acid (omega-7). No clinical dermatitis severity endpoint reported. Mechanistic/biomarker study underpinning the Yang 1999 trial.

Finding: Active formulation produced statistically significant improvements in skin hydration (p=0.0003) and TEWL (p=0.0087) vs placebo over 12 weeks in healthy volunteers. Very small sample (n=13), topical not oral, healthy not diseased — pilot/early-phase evidence only.

Finding: Healing period was significantly shorter in the sea buckthorn cream arm vs 1% silver sulfadiazine (p<0.001). Active comparator (not placebo), single-center, modest sample — supports a topical wound-healing signal but not generalizable to consumer 'skin health' supplementation.

Finding: Authors conclude that despite compelling preclinical data on omega-7/vitamin-rich anti-inflammatory effects, human RCT evidence for skin endpoints is sparse, small, and heterogeneous; they explicitly call for large, multi-center, double-blind RCTs to validate efficacy, particularly for moderate atopic dermatitis. No quantitative meta-analytic pooling was possible.
