The most common and standard use of succinic acid is as a pH regulator and cell metabolism enhancer in dietary supplements, and as an anti-inflammatory and antibacterial active ingredient in cosmetics for problematic skin.
In practice:
In dietary supplements, it supports the Krebs cycle and improves oxygen and energy utilization in cells, resulting in greater vitality and resistance to oxidative stress.
In cosmetics, especially those for acne-prone, oily or mature skin, it helps reduce inflammation, promotes skin regeneration and has an exfoliating effect, improving skin texture and tone.
It is also a mild preservative and buffering agent, so it often appears as an ingredient that promotes the shelf life and stability of formulations.
