Castor oil to reduce wrinkles?

Wrinkles gradually form over the course of life. The first usually appear around the age of 25 - 30 years, following the decrease in synthesis of collagen and elastin by the fibroblasts. This leads to a loss in skin flexibility and elasticity, as well as its thinning. The epidermis also produces less sebum , which increases skin dryness and promotes the appearance of wrinkles and fine lines.

Skin sagging is also exacerbated by frequent exposure to the sun's ultraviolet rays, which is the cause of photoaging. This leads to an increase in the rate of free radicals in the body, reactive oxygen species that cause damage to DNA, proteins, and cells, and promote skin aging mechanisms. Another aggravating factor is smoking. Indeed, cigarettes themselves contain several free radicals.

Castor oil is a vegetable oil obtained through cold extraction from the seeds of the castor plant. This shrub is native to Central Africa. The use of castor oil dates back to ancient Egypt. It is said that Queen Cleopatra regularly used it as a makeup remover and to brighten the whites of her eyes. Today, castor oil is incorporated into many cosmetic products under its INCI name Ricinus Communis (Castor) Seed Oil. Although this botanical extract has many benefits for the skin and hair, no scientific study to date has demonstrated its effect on wrinkles and fine lines. However, it has several properties that allow it to delay their appearance.

• The vegetable oil of castor aids in the preservation of the hydrolipidic film.

  Castor oil contains several saturated and unsaturated fatty acids, active ingredients that ensure proper skin hydration. These molecules largely make up the composition of the hydrolipidic film , a watery/oily mixture that helps to slow down water loss and protect the skin from external aggressions (bacteria, UV, pollution...). In doing so, the fatty acids in castor oil prevent the appearance of dehydration fine lines. These small superficial streaks appear on the areas of the face where the skin is most fragile and are caused by a weakening of the skin barrier and the hydrolipidic film, leading to the gradual evaporation of water from the epidermis.

• The vegetable oil of castor protects skin cells from oxidative stress.

  Castor oil also contains tocopherols (vitamin E), which are powerful natural antioxidants. These molecules work by neutralizing free radicals through an electron donation before they can damage skin cells (keratinocytes and melanocytes). Therefore, castor vegetable oil has a photoprotective action that delays skin sagging.

How to use castor oil?

• Pure.

  In prevention of skin aging, you can apply pure castor oil to your face or body. To do this, take a few drops of oil and apply them over the entire area. Then gently massage in a circular motion so that the oil is effectively absorbed by the skin. However, it should be noted that castor oil has a rather thick and greasy texture, and it is preferable to use it only in the evening.

• Diluted in a cream.

  You can also use castor oil in synergy with your moisturizing cream. To do this, take a dollop of cream in the palm of your hand and add one or two drops of castor oil. You can then apply the treatment by gently massaging it in.
