Science
Mechanism of Action
It functions by integrating a high concentration of polyunsaturated fatty acids (PUFAs), specifically Linoleic and Alpha-Linolenic acids, into the stratum corneum to reinforce the lipid barrier and prevent trans-epidermal water loss. Additionally, its content of Gamma-Linolenic Acid (GLA) and plant sterols helps modulate inflammatory responses while tocopherols defend against oxidative stress.

Key findings
- 01 Topical application at 0.5%-1.5% in emulsions significantly improved skin hydration and lowered TEWL within 7 days.
- 02 A hemp-based clinical mask trial demonstrated a 65.7% increase in moisture levels and a 12.9% reduction in erythema.
- 03 Gold-standard research confirms high PUFA content effectively alleviates symptoms of atopic dermatitis and chronic dryness.

Dusting Analysis
Because of its marketing appeal, brands often include it at 'trace' levels (below 0.1%). However, clinical data suggests physiological benefits for barrier repair and hydration begin as low as 0.5%.
