Our take
Is Sodium Succinate a Good Ingredient?
It rates Fair as an effective pH buffer that indirectly supports skin comfort, but direct skin benefits are limited; irritation risk is low though possible at higher concentrations or in very acidic or alkaline systems.
What it does
Skin Benefits
It helps keep formulas comfortable on skin by moderating acidity, which may reduce the chance of sting from actives, though skin benefits here are indirect and mainly formulation-supportive.

Uses in Skincare & Cosmetics
It's used in toners, serums, and cleansers to hold a steady pH in acid-containing or sensitive-skin formulas.
Before you use it
Safety
It's typically low irritation and well tolerated as a buffering salt. It's unlikely to cause issues, but stinging can occur in formulas with strong actives or extremes of pH.
