PEG-114 POLYLACTIC ACID

Description

PEG-114 Polylactic Acid is a synthetic polymer that combines polyethylene glycol (PEG) with polylactic acid (PLA). This innovative ingredient serves multiple functions in skincare and cosmetic formulations. As a film-forming agent, it creates a smooth, breathable layer on the skin, providing a temporary protective barrier. This property also contributes to its ability to enhance the texture and spreadability of products.

The PEG component of this ingredient acts as a humectant, attracting and retaining moisture to help keep the skin hydrated. Meanwhile, the polylactic acid portion offers potential exfoliating benefits as it can break down into lactic acid over time. This gentle exfoliation may help improve skin texture and tone.

PEG-114 Polylactic Acid is often used in anti-aging formulations due to its ability to temporarily plump and smooth the appearance of fine lines. It can also function as an emulsion stabilizer, helping to maintain the consistency of products containing both oil and water-based ingredients. While generally well-tolerated, individuals with sensitive skin should patch test products containing this ingredient, as the PEG component may cause irritation in some cases.
