Rubus Idaeus (Raspberry) Fruit Extract

Rubus idaeus (raspberry) fruit extract is popularly known as red raspberry to differentiate it from other types. This fruit gets its red colour from the presence of antioxidant compounds known as anthocyanins.

Raspberry fruit contains a broad mix of antioxidants, including ascorbic acid (vitamin C) beta-carotene, glutathione, quercetin, and vitamin E.

Raspberry is also a source of a type of polyphenol known as ellagitannins, such as those from antioxidant ellagic acid. This group of tannins does not possess an astringent quality.

Applied to skin, red raspberry can inhibit enzymes in skin that lead to signs of discolourations and loss of firmness. Of course, these benefits also rely on daily use of broad spectrum sunscreen to protect skin from exposure to UV light.Speaking of UV light, research has also shown topical application of red raspberry extract helps skin defend itself in the presence of UVB light.

Raspberry fruit extract works through its polyphenol content, which acts as an antioxidant to neutralise free radicals in skin cells. This helps protect against oxidative stress, which can contribute to premature ageing and skin irritation.

The astringent action comes from compounds that temporarily tighten and tone the skin, potentially helping to refine pore appearance and create a more refined skin surface. The extract also appears to support the normal function and survival of both keratinocytes (outer skin cells) and fibroblasts (deeper connective tissue cells).

Rubus Idaeus Fruit Extract is typically used as a supporting ingredient within broader formulations rather than as a standalone treatment. It works well in toners, essences, and hydrating serums where its astringent and antioxidant properties complement other actives. Use as directed by the product instructions, usually once or twice daily as part of your regular skincare routine.
