All the information you need to know about turmeric.

Turmeric is a natural ingredient rich in molecules beneficial for the skin, responsible for the various benefits it provides to the skin and hair. The table below shows the different active ingredients found in turmeric, along with their main associated properties.

The turmeric is a coveted ingredient in cosmetics, due to the numerous benefits it brings to the skin.

• Antioxidant.

  Curcumin, the active ingredient in turmeric, has a protective effect on cellular organelles and defends the skin against the action of free radicals due to its chemical structure composed of double bonds. This allows it to donate an electron to these reactive and unstable molecules and prevent the genetic mutations and oxidative damage they can cause. Thus, turmeric has a photoprotective potential and is an excellent ally for preventing the appearance of wrinkles.

• Antibacterial.

  Curcumin has been studied for its antimicrobial and antibacterial properties. Scientists have demonstrated that it is effective against several strains of bacteria such as Cutibacterium acnes and certain dermatophytes, contributing respectively to the development of acne and eczema. Notably, curcumin inhibits FtsZ, a protein necessary for bacterial cytokinesis, the final stage of cell division. By preventing it from performing its role, curcumin prevents bacterial multiplication.

• Stimulates microcirculation of blood.

  This property of turmeric powder is again due to curcumin. Studies have shown that this molecule is capable of stimulating microcirculation of the blood. This property is beneficial in combating several issues, particularly certain types of dark circles and bags under the eyes, but also in cases of heavy legs.

• Healing.

  Curcumin also acts on the TGF-β1 growth factor and increases its expression. This results in improved tissue epithelialization and promotes angiogenesis, the process of synthesizing new blood vessels. Thus, curcumin accelerates the skin healing process, including in areas affected by acne lesions or psoriasis.

• Anti-inflammatory.

  Curcumin influences various inflammation mechanisms in the body. It first inhibits the induction of the COX-2 membrane protein, a protein that releases prostaglandins, which play a pathological role. Curcumin is also capable of preventing the synthesis of certain pro-inflammatory cytokines, such as interleukins 1α and 6 (IL-1α and IL-6) as well as the tumor necrosis factor (TNF-α). These various actions of curcumin make turmeric powder a valuable ally in cases of redness, pain, or itching.

• Brightening.

  Turmeric is sometimes incorporated into treatments targeting pigment spots, as it contains several active ingredients that act on melanogenesis. These include curcumin, which has an inhibitory effect on the activity of tyrosinase, the enzyme that allows the conversion of tyrosine into melanin, and alpha-turmerone. The latter prevents the synthesis of the hormone α-MSH (α-Melanocyte-Stimulating Hormone), a hormone that activates certain melanocortin receptors. These receptors trigger the production of melanin.

The turmeric is a natural ingredient whose topical application presents almost no contraindications. For example, it is suitable for pregnant women, as well as young children. Caution is only necessary if you have a food allergy to turmeric. This does not necessarily lead to a cosmetic allergy, but it is still recommended to apply a principle of caution and seek advice from a primary care physician in case of doubt.
