Compatibility
Works well with:
Hyaluronic Acid Glycerin Niacinamide Panthenol Sodium PCA Ceramides
Trehalose is broadly compatible with most cosmetic ingredients and is well-suited for use alongside other humectants and skin-conditioning agents. It is stable across a wide pH range and does not typically react with common actives or preservatives. No significant incompatibilities are well-documented in cosmetic formulation literature.
Formulation notes
Trehalose is a naturally occurring disaccharide found in organisms such as fungi, insects, and plants that survive extreme dehydration; it forms a protective glassy matrix around cell membranes and proteins to prevent moisture loss and structural damage. In cosmetics, it functions as a humectant and skin-protectant, helping to maintain skin hydration and reinforce the skin barrier under environmental stress. It is considered well-tolerated with a low sensitization potential, making it suitable for sensitive and reactive skin formulations.
