Skin Aging: Can Turmeric Combat Wrinkles?

Skin Aging: Can Turmeric Combat Wrinkles?

As witnesses of the passage of time, wrinkles are the result of the loss of firmness and elasticity in the skin due to the aging of certain cellular components. While it is not possible to completely erase them once they have formed, certain active ingredients can slow their onset and reduce their appearance. Let's explore the benefits of turmeric against wrinkles.

Skin aging: what are the mechanisms at work?

Wrinkles are the most visible signs of skin aging, particularly on the face. One of the causes of these grooves is the natural decrease in the production of collagen, elastin and hyaluronic acid over time. These molecules indeed allow for the flexibility, elasticity, and hydration of the skin. The cell renewal also tends to decrease over the years. Other factors accelerate skin sagging. This is particularly the case with pollution , UV rays and tobacco which generate oxidative stress in the skin cells. This notably damages the collagen and elastin fibers.

Turmeric powder: its effects on skin laxity.

Recognizable by its yellow color, the turmeric powder is a spice produced from the rhizome of the Curcuma longa, a herbaceous plant belonging to the Zingiberaceae family. This ingredient contains a multitude of compounds such as curcumin, its active principle, alpha-turmerone, campesterol, caryophyllene, and even vitamins. In Asia, turmeric is used as a traditional medicinal plant due to its antioxidant and anti-inflammatory properties. It is also incorporated into various cosmetic treatments, such as creams, gels, masks...

Turmeric is often incorporated into treatments targeting signs of aging. However, it does not directly combat wrinkles, but rather has a preventive action. Turmeric notably possesses antioxidant properties and a protective effect on elastin, conferred by the curcumin it contains.

This molecule indeed protects cellular membranes against peroxidative damage caused by free radicals. Lipid peroxidation is a chain reaction leading to the damage of cellular membranes and the disruption of the hydrolipidic film. Curcumin inhibits this peroxidation thanks to the double bonds present in its chemical structure. These double bonds allow it to rearrange from a structural point of view and donate an electron to free radicals. This electron donation stabilizes and neutralizes these species before they can damage cellular constituents.

It has also been demonstrated that curcumin contributes to blocking elastase, an enzyme that catalyzes the hydrolysis of elastin, meaning its degradation. Curcumin works by stimulating the activity of α1-antitrypsin, a natural inhibitor of elastase transcription. Thus, turmeric protects the skin from loss of elasticity and firmness, which is correlated with the deterioration of elastin fibers.

The radiance mask by Typology to prevent photoaging.

One of the major causes of the appearance of aging signs is exposure to the sun's UV rays, responsible for photoaging. To prevent the proliferation of free radicals, which are responsible for accelerating skin aging, we recommend our radiance mask. Enriched with turmeric powder (INCI: Curcuma Longa Root Extract), yellow clay (INCI: Kaolin), and lemon verbena hydrosol (INCI: Lippia Citriodora Leaf Water), it revitalizes the epidermis and protects it from the effects of oxidative stress, thus having a preventive action on wrinkles. In addition, this mask leaves the complexion even and luminous after application. It also has a "purifying" activity and contributes to refining the skin texture.
