why we use hydroxyacetophenone

A Multi-Functional Antioxidant and Soothing Agent

Hydroxyacetophenone is a powerful antioxidant and calming ingredient known for its free radical-scavenging abilities and its role in enhancing skincare formulations. As a phenolic antioxidant, it works synergistically with other antioxidants, boosting their efficacy while protecting the skin from oxidative stress. This helps to neutralise environmental aggressors, such as pollution and UV radiation, which contribute to premature ageing and skin damage.

Skin-Soothing and Anti-Irritation Properties

Beyond its antioxidant power, hydroxyacetophenone acts as a soothing agent by inhibiting cyclooxygenase-2 (COX-2), an enzyme linked to inflammation and skin irritation.1 By modulating the inflammatory response, it helps to reduce redness, sensitivity, and discomfort, making it particularly beneficial for reactive and stressed skin.

Preservative-Boosting and Stability Support

In addition to its skin benefits, hydroxyacetophenone plays a key role in enhancing formulation stability. It supports the efficacy of preservatives, helping to maintain the mildness and integrity of cosmetic formulations. This ensures that skincare products remain safe and effective while minimising the microbial burden. This preservative-boosting benefit may also lead to a reduction in the concentration of additional preservatives required.

Nature-Identical and Sustainably Sourced

While hydroxyacetophenone is synthetically manufactured for purity and consistency, it is also found naturally in cloudberries. This nature-identical composition ensures that it delivers the same potent antioxidant and soothing benefits, while allowing for a sustainable and controlled production process.
