Face serum is a lightweight, rapidly-absorbing topical skincare product formulated with high concentrations of active ingredients such as antioxidants, vitamins, and peptides. These ingredients work to correct specific skin concerns such as signs of ageing, dehydration, dullness, blemishes and hyperpigmentation. Their lightweight nature means serums have a smaller molecular size than other products, like moisturising creams or facial oils. This allows them to be absorbed more easily which means the high amount of active ingredients can be delivered rapidly and deeply to the skin. As a result, visible results can often be seen in a shorter amount of time compared to other skincare products. Examples of active ingredients in serums include: Encapsulated retinol: An anti-ageing all-star, encapsulated retinol targets signs of ageing, hyperpigmentation and blemishes. The encapsulated delivery system reduces the irritation commonly experienced by new retinol uses. Hyaluronic acid: Delivers a big drink of water to thirsty skin cells. Hyaluronic acid is a molecule that physically binds water in the skin for a plump, dewy looking complexion. Niacinamide: Works to reinforce the skin barrier while calming inflammation. Vitamin C: Diminishes the signs of hyperpigmentation and uneven skin tone for a more radiant, unified complexion. Vitamin C can also stimulate collagen production to increase firmness and neutralise free radical attacks which accelerate signs of ageing.
