What are the benefits of succinic acid for the skin?

The succinic acid possesses antimicrobial properties, making it an effective ingredient in cosmetic formulations. At concentrations as low as 0.1%, it can inhibit the growth of bacteria such as Streptococcus mutans and Cutibacterium acnes, which are often involved in the development of skin blemishes, by more than 99.9%. By limiting the proliferation of these microorganisms, the succinic acid helps to improve the appearance of blemish-prone skin. However, to confirm this observation, in vivo studies would be necessary to demonstrate the clinical efficacy of succinic acid on skin blemishes.

In addition to its antimicrobial effects, succinic acid is suggested to possess anti-inflammatory properties. Studies have indicated that it may play a role in the modulation of inflammatory responses, as observed in conditions such as sepsis, where elevated levels of succinic acid are linked to a modified immune response. This acid has been shown to contribute to the reduction of redness and inflammation, which is particularly interesting for skin prone to irritation and blemishes.

However, it is important to note that more specific research is needed to establish the effectiveness of succinic acid in skincare. For instance, a recent study on amber teething necklaces revealed that there was no solid evidence that the succinic acid has anti-inflammatory effects when applied topically to the skin. Moreover, tests on macrophages showed that succinic acid did not lead to a reduction in inflammatory cytokines and could even be toxic at high concentrations. Understanding these mechanisms of action and their clinical implications can help to better define the role of succinic acid in skincare and establish connections with other skin concerns.

Research shows that succinic acid can contribute to skin hydration. By strengthening the skin barrier, it helps to seal in moisture and soothe inflammation, while improving skin elasticity. These hydrating properties are essential for maintaining healthy, radiant skin, particularly for sensitive skin or skin prone to dryness.

Succinic acid plays a crucial role as an antioxidant, protecting the skin from free radicals that are responsible for premature ageing. By neutralising these harmful agents, it helps to shield the skin from external aggressors, while also enhancing the stability of formulations. However, it would be pertinent to conduct clinical studies to assess the impact of these antioxidant properties on skin tone and elasticity.

Research suggests that succinic acid could inhibit the degradation of collagen, a vital protein for maintaining skin firmness and elasticity. As a regenerative ingredient, it is used to prevent the onset of skin ageing signs. It would be interesting to further explore the mechanisms of action at the cellular level, particularly how succinic acid interacts with fibroblasts to support collagen synthesis.

Succinic Acid promotes the regeneration of skin cells by increasing their energy through the stimulation of mitochondrial activity. This mechanism can have beneficial effects on skin tone and improve overall appearance. However, it would be essential to investigate whether clinical trials have demonstrated an improvement in skin tone and appearance due to this property.

Succinate, a derivative of succinic acid, plays a fundamental role in the inhibition of hyperproliferation of skin cells by activating mitochondrial respiration. This property is particularly relevant for treating skin disorders such as hyperkeratosis. Clinical studies could help establish a correlation between this regulation and an improvement in skin conditions.
