Spearmint and Peppermint, botanical characteristics.
The green mint carries the botanical name of Mentha spicata L. It is primarily distinguished by its light green, veined leaves. Unlike peppermint leaves, these are lacking a petiole (the narrowed part of some leaves towards the stem). Green mint emits a fragrance that is softer and more subtle than peppermint. It is characterized by its richness in carvone.
Peppermint is identified under the botanical name Mentha piperita L. It is a hybrid species, resulting from the crossbreeding of watermint and spearmint. It is taller than spearmint, with its height reaching up to 80 cm. Its leaves are darker, generally taking on a beautiful dark green color. Peppermint contains more menthol than spearmint, hence its more pronounced characteristic smell.
Peppermint and spearmint share a common geographical origin:theIndia, specifically the province of Uttar Pradesh.
Peppermint in Cosmetics.
This species of mint can be used in three main forms in skin and hair care.
Thepeppermint essential oil (INCI name: Mentha Piperita Leaf Oil)
This essential oil limits imperfections; it is recommended for oily skin as well as acne-prone skin. Indeed, it has a purifying and astringent action.
Its purifying properties also work on the scalp. Peppermint essential oil activates the microcirculation of the scalp and strengthens hair follicles to stimulate hair growth. Furthermore, it helps combat dandruff and seborrheic dermatitis issues. Because of these benefits, you can find it in the scalp scrub PHA 5% + jojoba beads. This pre-shampoo exfoliating gel gently removes dead cells for a healthy and balanced scalp. Peppermint essential oil is also in our scalp treatment purifying Zinc PCA 4% + nettle extract. This treatment regulates sebum production and purifies the scalp to prevent it from becoming too oily too quickly.
Thepeppermint hydrosol (INCI name: Mentha Piperita Flower/Leaf/Stem Water)
Due to its acidic pH, peppermint hydrosol visibly tightens pores. Thanks to its purifying properties, it is also recommended for acne-prone skin. Ourpeppermint hydrosolis obtained through distillation from peppermint leaves sourced from organic farming, grown and harvested in France. This treatment is suitable for combination to oily skin as well as enlarged pores. It is applied morning and evening, after skin cleansing, using a cotton pad or directly with the fingers.
Note! The advantage of floral water compared to peppermint essential oil is that it is not allergenic and can be used by all skin types, as well as by pregnant and breastfeeding women and children.
The peppermint oil macerate (INCI name: Mentha Piperita Leaf Extract)
To obtain this ingredient, fresh peppermint leaves are steeped in virgin sunflower oil. Soothing and refreshing, the peppermint macerate provides a sensation of freshness upon application and a mentholated taste to lip care products. It is thus present in our tinted balm for lips and cheeks.
The role of spearmint in skincare.
In cosmetics, spearmint is present in the following two forms.
Theessential oil of spearmint (INCI name: Mentha Spicata Leaf Oil)
The carvone, predominantly present in this essential oil, aids in healing by promoting skin regeneration after an injury. This substance is thus suitable for all skin types, but particularly for skin with blemishes such as acne scars. Because of this property, spearmint essential oil is included in our skin rebalancing cleanser with nettle. This purifying face and body cleanser is suitable for all skin types, particularly combination to oily skin, prone to imperfections.
Caution, this essential oil is not recommended for babies, children, people with epilepsy, and pregnant and breastfeeding women, as it contains significant amounts of carvone (ketone). This molecule is potentially neurotoxic and abortifacient at high doses. Thus, the IFRA 49th Amendment statement indicates that this essential oil can be used safely up to a concentration of 0.24% for rinse-off products due to the presence of carvone.
The hydrosol of spearmint (INCI name: Mentha piperita Leaf Water)
Similar to peppermint hydrosol, spearmint hydrosol is also astringent and purifying. It sanitizes blemished skin, soothes inflamed pimples, and tightens pores. With its refreshing action, it also affects the micro-venous and lymphatic circulation.
