During pregnancy, the expectant mother undergoes numerous phases of change, both in terms of her body and her skin. Certain areas, such as the stomach, are specifically stressed during this period. To soothe them, some pregnant women turn to calendula oil. However, is this suitable during pregnancy? Learn more here.

Can calendula oil be used safely during pregnancy?
The calendula oil is a macerate obtained by steeping fresh or dried flowers of this plant in a neutral oil, typically sunflower oil, jojoba oil or sesame oil. This ingredient is primarily known for its soothing properties, which stem from its richness in flavonoids and terpenoids. Several studies have shown that these bioactive constituents are capable of inhibiting certain pro-inflammatory cytokines, such as IL-1β, IL-6, TNF-α and IFN-γ. The use of calendula is particularly recommended for sensitive skin or skin prone to inflammation. However, questions may arise about its safety for pregnant women.
When applied topically, calendula oil is suitable for the skin of pregnant women.
When it comes to oral intake, caution is advised. Indeed, the marigold macerate is suspected of having potential uterine-stimulating effects, meaning it could trigger uterine contractions. These can be dangerous during pregnancy and increase the risk of miscarriage, particularly during the first and second trimesters. That's why the intake of uterine-stimulating substances is contraindicated for pregnant women, except under medical supervision. As for marigold oil, its potential uterine-stimulating action is currently only suspected and there is very little information on this subject in the scientific literature. No hypothesis has been put forward about its possible mode of action.
The benefits of calendula oil for pregnant women?
Calendula oil could be beneficial during pregnancy to prevent stretch marks. Indeed, depending on the carrier oil used during maceration, it can be more or less rich in oleic acid, a fatty acid naturally present in sebum. Calendula oil could therefore strengthen the hydrolipidic film on the skin's surface, thereby protecting the integrity of the skin barrier and reducing water loss. With increased hydration and flexibility, the skin would then be less prone to stretch marks. The calendula oil macerate also has an interesting healing potential, as demonstrated in various clinical studies. It can indeed stimulate fibroplasia, keratoplasia and angiogenesis. This ingredient thus positively impacts the proliferative phases of the skin wound healing process, suggesting that it might possibly have an effect on purple stretch marks.
The potential use of calendula oil for performing perineal massages prior to childbirth has also been explored. These massages help prepare all the muscles of the perineum for childbirth and reduce the need for an episiotomy, a surgical procedure that involves incising the perineal muscles to facilitate the baby's passage during childbirth. A trial involving 234 women experiencing their first pregnancy was conducted. The volunteers were divided into two groups: the women in the first group were instructed to perform a ten-minute perineal massage daily from the 34th week of pregnancy until childbirth using calendula oil, while those in the second group did not perform any massage. The results of the study are compiled in the table below.
| Results | Massage Group | Control Group |
|---|---|---|
| Intact Perineum | 29.8 % | 40 % |
| Episiotomy | 20 % | 18.9 % |
| First-degree perineal tear | 73.3 % | 78.9 % |
| Second degree perineal tear | 26.7 % | 19.3 % |
| Third-degree perineal tear | 0 % | 1.8% |

This study, however, did not demonstrate the benefit of calendula oil in preventing perineal tears during childbirth. Indeed, the results presented above are not significant, meaning they do not show a statistically valid difference between the use of calendula oil in massage and the absence of massage. That being said, the calendula macerate, possessing hydrating, healing, and soothing properties, remains an interesting ingredient for caring for the delicate skin of pregnant women.
