About this ingredient
Diethyl Succinate (INCI: Diethyl Succinate) is an ester that works as a solvent. In a formula it helps dissolve poorly soluble actives and improves the product's texture and spread. Place it as a functional component, not a skincare active. It does not treat wrinkles, pigmentation or redness; its job is formula support, helping other ingredients stay stable and well dispersed. In that role it is reliable. Applied topically it has no systemic relevance, so it can be used during pregnancy and breastfeeding. Tolerance is good, with low irritation and allergy potential. It does not clog pores and suits sensitive skin. As with any solvent, its behavior depends more on the full formula than on the ingredient itself.
