Polyglyceryl-3 Stearate …

Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Crosspolymer is a synthetic polymer derived from glycerin and fatty acids. It functions as both a humectant and skin conditioning agent, meaning it draws moisture into the skin whilst also helping to soften and smooth the skin surface.This ingredient is used in formulations to improve texture, enhance hydration, and create a more pleasant sensory experience. It's a multi-tasking component designed to work alongside other active ingredients in a skincare routine.

As a humectant, this polymer works by attracting water molecules from the environment and deeper skin layers, helping to bind moisture to the stratum corneum (the skin's outermost layer). This can help reduce transepidermal water loss and support overall hydration.Its conditioning properties come from its structure, which can coat the skin lightly, creating a smoother appearance and improving how skincare products feel during application.

This ingredient is typically found in moisturisers, serums, and hydrating products where it works as part of the overall formulation. It's passive in use — simply apply your product as directed and allow it to absorb. It plays well with most other skincare ingredients and has no specific timing or combination requirements.

Generally well-tolerated and considered safe for cosmetic use. Synthetic polymers of this type have a long history of use in skincare without significant safety concerns reported.
