A Mixture of Water-Soluble Polysaccharides Reduces Caspase-1 and IL-1β Inflammatory Responses by in vitro in Reconstructed Human Epidermis (RHE).

Introduction: It is well established that () is a common skin commensal microorganism that has been linked to acne. In acne flare-ups, can be found in abundant levels within the inflammatory lesions (called comedones) associated with the skin disease. Recently, it was reported that 3D reconstructed human epidermis (RHE) treated with viable cultures of can elicit β-defensin antimicrobial peptide responses in the skin and can weaken the skin barrier of the RHE after three days of exposure to .

Passive Enhancement of Retinol Skin Penetration by Jojoba Oil Measured Using the Skin Parallel Artificial Membrane Permeation Assay (Skin-PAMPA): A Pilot Study.

Introduction: Retinol is known to have positive benefits on the skin including enhancements in barrier function, increased epidermal thickness, reductions in fine lines and wrinkles and reductions in hyperpigmentation. Improved methods to enhance the penetration of retinol are desirable.

Methods: A study was conducted to examine if addition of natural jojoba () oil might help passively enhance the penetration of retinol through the skin's lipid barrier.
