Raspberries

Raspberries have an astringent effect on the skin, making them particularly helpful for oily skin and enlarged pores. Their intensely hydrating properties also make them excellent for dry and mature skin and for tackling wrinkles. Raspberries are a rich source of vitamin C, which helps the absorption of iron, essential for beautiful skin, as well as vitamin A, the natural pigment anthocyanin, minerals such as phosphorus, iron and zinc, folic acid and fibre. They contain biotin, the beauty vitamin from the B vitamin complex, which contains sulphur, important for healthy-looking skin, nails and hair. They can protect the skin from sunlight. Raspberries deeply cleanse the skin and tighten pores while nourishing and replenishing it. They also have a preventative effect, as pores gradually tighten, helping to prevent blackheads, inflammation of sebum within the pores and subsequent acne. They help with inflammatory skin conditions. Originally native to Europe, raspberries were gathered as early as the Stone Age, and their healing properties were known to ancient physicians, who used their juice for digestive problems. Today, natural organic extracts are obtained from raspberry stem cells or seeds, often bound to maltodextrin for stability in cosmetics.

Their mechanism of action includes intensive hydration: raspberry stem cell extract increases the amount of hyaluronic acid in the skin and supports collagen production, helping to restore the skin barrier and ceramide production. As a powerful antioxidant rich in anthocyanosides, polyphenols, flavonoids and vitamin C, it protects against free radicals and UV radiation. The AHA acids in raspberries gently exfoliate, cleanse and brighten the skin, while essential fatty acids and vitamin E from the seeds soothe irritation. The astringent effect tightens pores and helps prevent inflammation.

I recommend raspberries for oily skin with enlarged pores and a tendency to acne, dry and dehydrated skin, sensitive skin with eczema or irritation, and mature skin with wrinkles. Suitable for all skin types thanks to their balanced hydrating and sebum-regulating effects. Ideal for those seeking natural protection against ageing and sun damage.

A study published in the Journal of Agricultural and Food Chemistry (2004) demonstrated that raspberry seed extract at a concentration of 1 % inhibits 68 % of hyaluronidase activity, supporting skin hydration and elasticity. Further research in Phytotherapy Research (2011) showed that raspberry polyphenols at a dose of 50 µg/ml reduce inflammatory markers by 45 % in human keratin cells, confirming a soothing effect on acne and eczema.
