What are the contraindications for the use of pink grapefruit extract?

The extract of pink grapefruit is rich in antioxidant species that are excellent for the skin. However, this active ingredient has contraindications, and it is important to adhere to usage precautions. Here are the dangers of using pink grapefruit extract.

A closer look at pink grapefruit extract.

Pink grapefruit and pomelo are often confused. In fact, these two fruits belong to the genus Citrus, which includes the majority of citrus fruits. The grapefruit tree (Citrus maxima) produces enormous fruits, the grapefruits. However, this is not the one we consume in Europe! Indeed, it is the pomelo (Citrus paradisi) that is present in our supermarkets, whichis incorrectly called grapefruit.The confusion around the name of these two fruits has been ongoing for a long time and a change in nomenclature is not being considered.

The pink grapefruit, the ancestor of the pomelo, is consumed in the West Indies and Tahiti. Originating from China, it is sometimes sold in France under the name of Chinese pomelo.The pomelo, commonly called grapefruit in France, is a fruit resulting from the natural crossbreeding between the grapefruit tree (Citrus maxima) and the sweet orange (Citrus sinensis). While the grapefruit comes from Southeast Asia, the pomelo is native to the Caribbean.

In dermo-cosmetics, thegrapefruit extract (which is actually pomelo extract) is a powerful purifying and sanitizing ally for the skin.Known by the I.N.C.I. name "Citrus Paradisi (Grapefruit) Fruit Extract", this aqueous extract is obtained by microwave extractionfrom whole fruits derived from organic farming. No preservatives are added to the final product. The recommended percentage of this natural ingredient in a cosmetic formula is 3%.

What molecules does pink grapefruit extract contain?

The aqueous extract of pomelo is composed of the following molecules.

  • Alpha-hydroxy acids, AHA (primarily citric, tartaric, and malic acids): these active ingredients are stimulators of cellular metabolism that provide regenerative, keratolytic, brightening, and hydrating benefits to the skin.

  • Flavonoids (primarily hesperidin): these compounds provide antioxidant protection (UVA protection) and a brightening effect (tyrosinase inhibition), thus anti-spot.

  • Vitamins, sugars (mainly vitamins C and B, sucrose and glucose): these active ingredients provide revitalizing and hydrating benefits.

The extract of pink grapefruit is thus suitable for reactive and sensitive skin, oily to combination skin, as well as for tired, mature, or lackluster skin.

Use of Pink Grapefruit Extract: Dangers and Contraindications.

Despite its numerous benefits in cosmetics, pink grapefruit extract presents some contraindications and precautions.

  • It can cause reactions (redness or skin irritations) in certain individuals who are more or less sensitive. These skin reactions can be attributed to the presence of AHA in this aqueous extract, which can be irritating due to the peeling they cause. Always perform an allergy test. To do this, apply two drops in the crook of your elbow of the care product containing pink grapefruit extract. Wait at least 24 hours, or even 48 hours to observe any possible reaction.

  • It is advisable toavoid any sun exposure immediately after its applicationbecause grapefruit extract contains photosensitizing species (mainly citric acid, tartric and malic). We recommend always pairing the use of a pomelo-based care product with a broad-spectrum sun protection.

It should be noted that oral intake of pink grapefruit extract is not recommended if you are undergoing medical treatment. Indeed, it can either amplify or inhibit the effects of medications. Pink grapefruit extract can be toxic to the kidneys if ingested in high doses over a long period of time. It is intended for adults and teenagers and is not recommended for children under the age of 6.
