Proline
What Proline is & what it does
An amino acid humectant and conditioning agent that hydrates and helps maintain a smooth, supple surface. It is gentle and skin-compatible.
What does Proline do in skincare?
Proline is an amino acid that is commonly used as a skin conditioning agent and humectant. It can help support a hydrated, smooth skin feel and is one of the building blocks naturally found in skin proteins. In formulas it is generally added to contribute to a soft, conditioned surface.
Is Proline safe?
Proline is a naturally occurring amino acid that is widely used in cosmetics and generally considered safe in skincare at typical use levels. It is also found naturally in the body. Individual sensitivity is always possible, so a patch test is reasonable if you have reactive skin.
Is Proline vegan?
Proline used in cosmetics is often produced by fermentation or synthesis and can be vegan, but it may also be sourced from animal-derived materials. Whether a specific product is vegan depends on the supplier and the brand. Check the brand's certification or statements to confirm.
