It is important to know about up and coming personal care ingredients, so you are able to best answer potential client questions and know what works and what doesn't.
Laboratoires Expanscience has sourced sunflower seeds organically to optimize barrier function. Soline Bio (INCI: Helianthus Annuus (Sunflower) Seed Oil Unsaponifiables) was designed to promote the synthesis of key epidermal lipids in dry, atopic and mature skin.
Ceramides are the largest polar lipid class of the epidermis and play a major role in the regulation of the epidermal barrier, particularly in dry skins and in atopic dermatitis where ceramide concentrations are reduced. Cholesterol and cholesterol sulfate are the largest neutral lipid class of the epidermis and they play a role in the cohesion-dishesion properties of the epidermal horny cells and in the desquamation process.
The company reports that an emulsion containing 2% of the ingredient significantly increased the neosynthesis of cerebrosides, ceramides and cholesterol; led to a significant improvement of the moisturization of skin's outer layers with both immediate and long-lasting effects; and could positively and specifically modulate the epidermal lipid pattern ex vivo.
