Is carrot macerate really effective? Discover its benefits for skin and hair.
Known for its golden glow and revitalizing properties, carrot oil macerate has become a staple in natural skincare. But what do we really know about this plant-based elixir? How is it made, and what evidence supports its benefits for skin and hair? Let's take an in-depth look at this ancient ingredient in light of recent scientific data.
What is carrot macerate?
Carrot oil macerate is obtained by prolonged infusion of dried carrot roots in vegetable oil. This preparation allows the extraction of fat-soluble compounds such as carotenoids, including beta-carotene, a powerful antioxidant precursor to vitamin A.
Manufacturing methods: between tradition and innovation
Traditional cold or hot maceration
- Cold maceration The dried roots are immersed in a stable oil (sunflower, sesame, jojoba) at room temperature for several weeks. This slow method allows for better preservation of heat-sensitive molecules.
- Hot maceration When heated between 40 and 60°C, the oil accelerates extraction but requires careful monitoring to prevent beta-carotene degradation.
Extraction with oily solvents
More modern, this technique involves circulating vegetable oil under pressure through the plant material. This method optimizes the release of active compounds and shortens the extraction time. However, it requires specific equipment and technical expertise.
The skin benefits of carrot macerate
1. Antioxidant and anti-aging action
Visit beta-carotene and other antioxidants present in the macerate help neutralize free radicals, which are responsible for premature skin aging. It also stimulates collagen and elastin production.
2. Healthy glow effect
Its natural pigment content gives the complexion a slight tan, enhancing the skin's radiance and evenness.
3. Support for cell regeneration
Thanks to its richness in provitamin A and essential fatty acids, it promotes healing, skin repair, and the reduction of imperfections.
4. Protection of the skin barrier
Vegetable carrier oils provide omega-6 and omega-9 which strengthen the barrier function, limit water loss, and protect against environmental aggressions.
Carrot macerate and acne: moderate hope
Carrot macerate has no proven keratolytic or sebum-regulating properties. However, some of its components, such as’oleic acid exhibit anti-inflammatory activity in vitro, which may moderate the inflammation associated with acne. Preliminary studies also suggest antibacterial potential on strains such as golden staph.
On hair: what are the benefits?
Protection against oxidative stress
The scalp exposed to UV rays, pollution, or heat treatments can suffer oxidative damage. The macerate, rich in carotenoids, could contribute to neutralizing these effects.
Nourishing and firming effect
The fatty acids derived from the carrier oil help to strengthen the hair fiber, smooth the cuticles, and restore suppleness to dry lengths.
Soothing the scalp
Containing flavonoids and oleic acid, it could reduce irritation and redness, especially on sensitive scalps.
Instructions for use and precautions
- On the skin : Use as a night treatment or mix with a moisturizer. Be careful not to use too much on very fair skin to avoid temporary discoloration.
- On the hair : As an oil treatment or scalp treatment before shampooing.
- Texture Viscosity varies depending on the oil used. Some formulas may be too rich for acne-prone skin.
