Pacifica Vegan Collagen Overnight Recovery Cream Versus Pacifica Wake Up Beautiful Overnight Retinoid Cream

Chemically, it's a blend of esters from 14-18 fatty acids and alcohols that is a solid at room temperature but melts on contact with skin. It helps soften and smooth the skin while improving the feel and spread of products.

Typical use concentrations range from 1-10% (most commonly 2-5%).

The CIR Expert Panel has concluded it's safe as used and has shown no skin irritation in available studies.

Because it's a blend of fatty acid esters in the chain-length range that Malassezia can feed on, it may not be fungal acne safe.

Industry-reported use ranges from 8% in rinse-off products and 2% in leave-on formulations.

Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.

Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.

This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.

Just know very high concentrations (>40%) can feel tacky in low humidity.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
