Are there any contraindications to using calendula?

The calendula (Calendula officinalis) is a small plant belonging to the Asteraceae family. Its yellow/orange flowers are used in the formulation of certain cosmetic products. Considered a universal natural remedy for the skin, it is particularly suitable for people suffering from dry, delicate skin or who blush easily. Although there are not many scientific studies on the benefits of calendula, there are, however, many anecdotal and potential benefits.

• Reducing skin inflammation: Applying calendula oil to the skin could help to soothe redness and inflammation, as well as alleviate feelings of skin discomfort. This is why calendula is a popular treatment and potentially beneficial for people suffering from inflammatory skin conditions, such as psoriasis, eczema and nappy rash.

• Treating minor injuries: Recent studies have shown that the use of a calendula ointment can speed up the healing of wounds in animals. It has even been used in another study among women who have undergone a caesarean section. Thus, calendula would promote healing and prevent wound infection, attributed to an antimicrobial effect. Other topical uses also include the treatment of first-degree burns, insect bites, small cuts, skin ulcers, etc.

• Slowing down the appearance of skin ageing signs: Studies also show that calendula could potentially increase collagen production, but it has not been extensively studied in humans. Incorporating this oil into your skincare routine would also enhance skin hydration, making it more supple and preventing premature ageing.

• Protecting the skin from harmful free radicals: Calendula oil contains a high content of antioxidants (flavonoids, carotenoids, etc.) that can help neutralise free radicals, thereby protecting cells from damage and inflammation. Consequently, calendula may help to reduce the dull appearance of the skin, fine lines and wrinkles.
